Editor’s Perspective

FACE Special Edition

Welcome to the 2023 FACE Special Edition, which covers the technology and development efforts behind The Open Group Future Airborne Capability Environment (FACE) Technical Standard. This magazine is the second of what is an annual issue, highlighting editorial content on FACE from the pages and website of Military Embedded Systems Magazine, together with the products aligned and certified conformant to the technical standard – all put together exclusively by our staff.

This issue is similar to our SOSA Special Edition, published in August each year covering the technology and innovation behind The Open Group Sensor Open Systems Architecture (SOSA) Technical Standard.

Both FACE and SOSA are examples of a Modular Open System Approach (MOSA) strategy, mandated by the U.S. Department of Department of Defense (DoD) for all new program designs and refreshes. A 2019 memo signed by the secretary of each service called MOSA a “warfighting imperative” and stated that “development of a modular open systems approach (MOSA) in areas where we lack them is vital to our success.” The missive mentioned FACE, SOSA, and other standards by name as examples of MOSA.

While FACE, founded in 2010, is a more mature standard than SOSA, they both share the goal of enabling commonality across multiple platforms through an open architecture approach that reduces long-term life cycle costs. Both the FACE and SOSA consortia also share industry and government members, demonstrating the support for these efforts.

“The founders of the FACE Consortium deserve credit for establishing a strong foundation and incorporating the MOSA principles,” said Joe Carter, Joe Carter, System Engineering Lead, U.S. Army PEO

[Program Executive Office] Missiles and Space and former Chair of the FACE Steering Committee, in a Q and A in the 2022 FACE Special Edition.

The success of FACE is seen in its adoption by major military platforms such as the Army’s UH-60V Black Hawk helicopter and the C-130J transport aircraft. For FACE procurement examples, visit: https://www.opengroup.org/face/ procurements

New platforms are also turning toward a MOSA process, with one example being the Army’s Future Long-Range Assault Aircraft (FLRAA) program. Bell Textron Inc., a Textron company, won the FLRAA development contract based on Bell’s V-280 Valor tiltrotor aircraft that was developed and tested as part of the Joint Multi-Role Technology Demonstrator (JMR TD) program. (See cover photo).

“Bell and its industry partners have systematically validated the V-280 aircraft and their [MOSA strategy] in collaboration with the Army,” according to Bell.

“Virtually every presentation from the U.S. armed services is driving a Modular Open Systems Approach (MOSA), and includes acronyms such as FACE, SOSA, and other open capability standards,” writes Ian Ferguson, Vice President of Marketing for Lynx Software Technologies, in an article titled “Lynx and RTI: The art of driving down mission-critical system costs” in the April/May Avionics issue of Military Embedded Systems.

“It is vital for the ecosystem of partners that are supporting the efforts of the military and aerospace industries to collaborate, so that our customers can reduce time-to-market, costs, and program risk for the next generation of best-in-class platforms,” he continues. “This means aligning behind and investing in solutions that conform to the important standards.”

Lynx is also the latest FACE member to achieve conformance certification. “Thanks to the expert guidance of our FACE Verification Authority (VA), LDRA, Lynx has just completed the conformance certification of our real-time operating system, LynxOS-178 to the FACE Technical Standard, Edition 3.1 for the FACE Operating System Segment (OSS) General Purpose Profile for PowerPC, Arm and Intel processor architectures,” Ferguson states.

Other certified FACE conformant suppliers include Collins Aerospace, Honeywell, L3Harris, Raytheon, Textron, ADLINK, RealTime Innovations, Inc.  (RTI), Skayl (DSDM), Ansys, Hanwha Systems, BlackBerry QNX, DDC-I, DornerWorks, Green Hills, and Wind River.

In addition to the certified conformant members, the consortium boasts more than 90 member organizations from industry, academia, and government. For a full member list, see page 10 of this issue.

MOSA approaches like FACE and SOSA continue to gather momentum and we’ll continue to cover them like we’ve covered open standards for 40 years at OpenSystems Media, dating back to our first publication – VMEBus Magazine – still published today as VITA Technologies.

Helping bring this issue together were Alicia Taylor, Reggie Hammond, and their colleagues at The Open Group. A big thank you as well to Chip Downing, who helped in his role with the FACE Outreach Subcommittee.

In this Q and A, Alicia Taylor, Program Director, The Open Group FACE Consortium, discusses the FACE approach, how FACE enables modularity across the acquisition life cycle, and expanding participation in FACE outside of the U.S.

Q: What is the Open Group FACE Consortium?

TAYLOR: The Open Group FACE Consortium is a government, industry, and academia collaboration that encourages innovation in refining business processes and developing vendor-neutral open standards which enable software portability, reusability, and interoperability. The two FACE Consortium software standards are the FACE Technical Standard and the Open Universal Data Description Language Standard (UDDL).

Q: What is the FACE Technical Standard?

TAYLOR: The FACE Technical Standard defines a reference and data architecture intended for the development of portable software components. The architecture is based on over 60 recognized

industry standards. The FACE Reference Architecture uses standardized interfaces and provides requirements for developing software components that will reside in architectural segments. The FACE Data Architecture describes the data and its semantics.

The open standards specified within the FACE Technical Standard allow use without payment or other obligation to the standards owners. Additionally, neither the FACE Technical Standard nor the FACE Conformance Certification Process require or prohibit a software supplier to relinquish rights to technical data or computer software within the software, the business logic, the presentation logic, or any other logic whether in the application or the software computing environment.

Q: Tri-Service leadership issued a mandate in 2019 to have a MOSA [Modular Open Systems Approach] strategy implemented for all new platforms and upgrades. Why have open architectures strategies become so important to the DoD?

TAYLOR: An open systems approach is not new and neither is modularity. The DoD started using MOSA in 2004 as a way to address rising costs and the need to get products to the warfighter faster. MOSA enables a modular architecture and an open business model to add, modify, or replace components across the acquisition life cycle.

This approach also facilitates technology refresh through the delivery of new capabilities or replacement technology without changing all components in the entire system. MOSA also sparks innovation by enabling operational flexibility to configure and

FACE

reconfigure available assets to meet rapidly changing operational requirements.

A MOSA strategy importantly enables cost savings/cost avoidance through the reuse of technology/components from any supplier across the acquisition life cycle. The FACE Technical Standard is an example and the FACE ecosystem addresses all five MOSA principles.

Q: How does FACE enable the modularity you mention?

TAYLOR: Typically, aircraft are built with platform-unique requirements by a single vendor where the capabilities are tightly coupled to the avionics, sensors, and operating system. The resulting software is unique to that aircraft, and without a modular approach and standard interfaces, each time we add a capability to the fleet we create new software for each aircraft type.

The FACE Approach changes this software architecture paradigm. The FACE Technical Standard created an open, layered architecture that allows any FACE software component to move from one aircraft platform to the next with minimal integration complexity on any desired hardware platform.

Q: What does being FACE conformant mean?

TAYLOR: FACE Conformance ensures proper use of the defined FACE Interfaces and adherence to the FACE Reference Architecture. In addition to conformance, the FACE ecosystem addresses other practical business concerns such as contracting (FACE Contract Guide), value proposition and business drivers (FACE Business Guide), and product registry (FACE Library documents).

Q: There are some common misconceptions regarding the FACE Technical Standard: One is that it is only for U.S military aircraft.

TAYLOR: The biggest potential for growth for the FACE Technical Standard

is outside of airborne platforms – from ground-control systems, to ground vehicles, to autonomous systems assisting dismounted soldiers, to supply chains to loyal wingmen. It is even being looked at for commercial aircraft platforms.

The FACE Approach also includes business processes, technical practices, and an open component-based software standard that can be used in almost any software environment. Over the last 12 years we were focused on the aviation software domain, but good software engineering is good software engineering regardless of the application domain.

Q: Is the FACE Technical Standard subject to export regulations or does it contain any U.S.-controlled information?

TAYLOR: Absolutely not! This is a common misunderstanding. The FACE Technical Standard is an open, nonproprietary specification that is publicly available without restrictive contracts, licensing terms, or royalties.

Q: What are some other misconceptions?

TAYLOR: One is that the FACE Technical Standard documents are proprietary. They are not. On our website, if you visit the docs and tools pages, you can download anything we have listed and use it freely.

Another is that the FACE Technical Standard is complex and cost-prohibitive. Also not true, as there is a long-term cost savings associated enabled by software reuse. We have proven through Technical Interchange Meetings (TIMs) and other integration events that using the FACE Technical Standard actually saves integration time.

Q: The FACE Consortium recently announced that it is opening membership and participation to companies and individuals outside the United States. Who is included in this expansion and what does it mean for the acceptance of the FACE Technical Standard?

TAYLOR: In November 2022, we announced that membership to the FACE Consortium is open to participation from companies and organizations in Australia, Canada, New Zealand, and the United Kingdom.

We are already seeing benefits of opening membership in terms of an increased desire to work together to find solutions to common problems and to better align standards. Many of our new members were already working in some capacity with our current members, but now we are starting those conversations about how to not only strengthen those relationships, but also to use new ideas to continue to evolve and improve the FACE Technical Standard and Ecosystem.

Q: The FACE Consortium has been around for more than 12 years; do you see (new or other) opportunities beyond current activities that may help accelerate adoption of the FACE Technical Standard, in a broad sense?

TAYLOR: People tend to push back on anything new. When the FACE Approach was developed, the rumor was that it was too complicated or too difficult to implement. As the Technical Standard and FACE work products matured, people started to realize the benefits of adopting open standards. The DoD is placing a greater emphasis on implementing open standards (FACE, SOSA, HOST, VICTORY, etc.) and industry is also seeing the benefits, not just in contracts, but in how software is developed.

SPECIAL EDITION
www.opengroup.org/face FACE Special Edition 2023 | 7

I believe that we as members of the FACE Consortium have to continue telling our “good news” story about the benefits of using the FACE Technical Standard. Opening up to international participation will have multiple benefits, to not only our current membership organizations who have international offices, but it will also allow greater participation and promote cooperation and synergy.

I believe we are going to have to look closely at how technology is transforming the way code is developed, automated, and integrated. Digital Engineering and Model based System Engineering are increasing the use of models and linking data together through those models to promote better collaboration. Our tool vendors are already taking advantage of some of those innovations by auto generating code and supporting the conformance process.

Q: What recommendations or advice would you share for new members to gain the greatest ROI from the FACE Consortium?

TAYLOR: The first FACE Consortium meeting I ever attended was in December 2015. I remember I was so lost. I did not even know enough to ask a question. I remember attending something called FACE 101 and even felt lost in the introductory overview. It felt like drinking from a fire hose. I tried reading the Technical Standard and the RIG –nothing really made sense. Fortunately, Terry Carlson and Joe Carter (then-chairs of the FACE Steering Committee) and others answered my questions and gave me the support I needed to increase my knowledge level. Over the years I have tried to use that experience in shaping how the IWS and the FACE Consortium supports new members, educates our members, and removes barriers. The FACE Consortium now has Overviews covering Business, Technical, Data Architecture, and Conformance. There is a Getting Started

QUESTION: HOW DOES THE FACE™ TECHNICAL STANDARD BENEFIT MILITARY AVIONICS SYSTEMS?

Standards: An essential first step but not the end

There are three challenges expressed to us by our customers every day, namely;

1. Driving down system costs to be competitive

2. Opening up systems to a broad spectrum of solutions and breaking apart vendor lock

3. Shifting from single-use software and hardware platforms to rapidly enable reuse

Fundamentally, this comes down to radically improving time to market for the next generation of industry-leading platforms and subsequent generations. This must be achieved despite rising system complexity as we shift from closed “black boxes” to “systems of systems,” whereby systems are constructed out of multiple connected subsystems. These subsystems are either inside an armored vehicle or a plane or, like the vision of the Connected Battlefield, a set of discrete, connected, distributed platforms that share information securely in real-time.

Aligning to standards is an essential first step. It is indeed exciting to see the increased momentum of companies rallying around the Future Airborne Capability Environment™ (FACE) Technical Standard to help

fuel the cadence of innovation. But as an ecosystem, we have a lot more we need to accomplish to support the higher-level objectives. Open system initiatives’ benefits hinge on engineers’ ability to reuse system components effectively. Today, we cannot simply insert a software component into a mission-critical system as easily as inserting a VPX card into a chassis. That is because standards

• Lack descriptions of expected behavior and side effects that can inform real-time and hazard analysis

• Do not account for the system information that’s needed to build, integrate and configure a comprehensive system to behave correctly

• Do not cover software components that reside in the operating system itself, such as drivers and health monitors

So, this is where we believe the ecosystem that services this category of use cases should be focused. And we must realize this vision together!

www.Lynx.com

Advancing the FACE™ Technical Standard

Throughout the years, TES-SAVi and TES-i have championed the implementation of each version of the Future Airborne Capability Environment™ (FACE) Technical Standard by constructing FACE PCS and PSS components, real-time operating system interfaces, and building FACE development and modeling tools like AWESUM® and FAME. During these endeavors, we have often discovered potential improvements to the standard, which we actively address through the FACE working groups. We now find ourselves deeply immersed in developing and integrating various FACE components for deployment on multiple aircraft. As a result, we have identified challenges that necessitate a stronger focus on real-world system development and integration support. Specifically, we see the need to:

• Expand mandatory Transport Service Segment (TSS) requirements to enhance compatibility and portability of PCS & PSS components.

• Reduce software code required for each UoC message by implementing methods such as grouping UoC interfaces.

• Minimize memory copies needed for sending and receiving messages, enforced by the multiple injectable interfaces in the TSS.

ADVERTORIAL

• Refine the Integration Model by incorporating an Action Language for specifying data conversions, transformations, and integrations.

• Implement UDDL and FACE DA proposals to bolster the usability and specificity of data models.

• Update the normative programming languages to reflect current standards.

While numerous FACE improvements can be addressed through FACE tooling, some challenges stem directly from the standard and cannot be “fixed” without modification. None of these changes or additions are “earth-shattering”; however, we must persist in enhancing and supporting the growing ecosystem of developers, integrators, and tool vendors, making the FACE approach a reality. The most striking revelation might be that besides these tweaks, there are no major additions needed for the FACE Technical Standard to support real deployments.

Q.WHAT IS THE KEY IMPETUS FOR THE FACE™ CONSORTIUM OPENING MEMBERSHIP TO THESE 4 COUNTRIES?

Our world is getting smaller and smaller. Cooperation between countries has increased including the development of standards. The United States (U.S.) Department of Defense (DoD) is calling for more cooperation with allies. Over the past several years, many organizations in these countries have inquired about joining the FACE™ Consortium. In addition, many existing FACE Consortium member organizations are international corporations, and have expressed a desire to enable their employees from other countries to participate. Since the US already has an alliance with these countries, the initial recommended international expansion was approved for this scope. Note: We do acknowledge that while there is an existing intelligence alliance among these countries, this is simply a coincidence, and has no relevance on membership in The FACE Consortium.

Q.HOW WILL INTERNATIONAL EXPANSION BENEFIT THE FACE™ CONSORTIUM OVERALL?

International expansion broadens participation in the FACE™ Consortium, allowing a more diverse group of members to create and evolve FACE Consortium work products that benefit the expanded market. It also brings in new ideas and expertise, allowing current members to learn from new members and vice versa. The expectation is a new synergy within the FACE Consortium.

Q.IS THE FACE™ TECHNICAL STANDARD SUBJECT TO EXPORT REGULATIONS OR DOES IT CONTAIN ANY U.S.-CONTROLLED INFORMATION?

Absolutely not! This is a common misunderstanding. The FACE™ Technical Standard is an open, non-proprietary specification that is publicly available without restrictive contracts, licensing terms, or royalties.

FACE in military avionics systems: Now let’s integrate it

It’s hard to escape the headlines around the Modular Open Systems Approach (MOSA), open standards, and individual initiatives such as those from The Open Group FACE Consortium, the creators of the Future Airborne Capability Environment (FACE) Technical Standard. In 2004, the Open Systems Task Force published a Program Manager Guide titled “A Modular Open Systems Approach (MOSA) to Acquisition.” Since then, the industry has seen a progression in policy guidance that raised the profile of MOSA and its applicability within military systems to enable success on the battlefield while lowering acquisition costs and promoting innovation.

The MOSA [Modular Open Systems Approach] strategy made its way into the National Defense Authorization Act language that was first signed into law for fiscal year 2017. In turn, this has flowed into requirements at the program manager level under the now-famous Tri-Services Memo: “MOSA for our Weapon Systems is a Warfighting Imperative,” issued by the U.S. Department of Defense (DoD) in 2019.

The FACE [Future Airborne Capability Environment] Technical Standard – as one of the named open standards endorsed by U.S. policy – was recently described by U.S. Army Brigadier General Rob Barrie as “integral to MOSA success by enabling modularity and promoting software reuse.” Programs such as the U.S. Army’s Future Vertical Lift call out the FACE standard as a requirement.

In today’s digitized avionics, most of the functional capability is implemented in software. Anywhere from 70% to 90% of that functionality depends on the selected equipment and how extensively it relies only on displays for the human-machine interface. The reality is that software development is hard; testing and certifying the safety of that software is hard. The need for greater functionality and adaptation of that

software to new situations is constant. The reality is that the old way of getting that software into aircraft fleets – which traditionally took years if not decades –now needs to be completed in weeks or days, sometimes hours.

By codifying a modular architecture, standard interfaces, data models, and conformance criteria into a common operating environment and reusable components, there now exists the means to share capabilities not only across platforms but also across the military services and avionics vendors.

The business benefits: Customers need not redo the development of a capability just to place it on a different aircraft. Components from different programs can be reused, with new components obtained

from a wider variety of suppliers. This approach increases competition and the delivery of innovative solutions.

Modularity and interchangeability: the vision of FACE

In short, this standardization of approaches for using open standards within military avionics systems promises to lower implementation costs, accelerate development, ensure robust architecture and consistently high-quality software implementation, and maximize opportunities for reuse. The FACE standard embraces these ideals by providing a modular reference architecture based on segments that can be integrated to meet final system requirements. (Figure 1.)

The content of each of those segments can and will vary depending on the preference of the system architect and the demands of the system under development. Despite those variations, modularity is ensured because the FACE standard defines the logical interfaces between the segments.

Each segment consists of one or more components. Each of those components must be shown to be fully conformant to the FACE standard applicable to the segment to which it contributes.

A FACE conformance test suite is used for that purpose, with a certification of conformance awarded following successful reviews by a FACE verification and certification

authorities. That successful review is then recorded on the FACE registry with the FACE library administrator.

Any component that has been certified in this way is known as a “Unit of Conformance” (UoC).

FACE operating system segment

The foundational system services reside in the FACE operating system segment (OSS). These services are provided by OSS UoCs and include the control of access to the computing platform, support for the execution of all FACE UoCs, and the hosting of operating systems interfaces. (Figure 2.)

The OSS is where the foundational element of FACE conformant systems is laid out. The platform software that resides directly on hardware runs here. The benefit of writing this code using FACE APIs is that it becomes far easier to migrate this code between different systems and different hardware. When the FACE standard was being defined, the consortium chose to harness existing standards such as POSIX and ARINC, both of which have withstood the test of time.

From a security perspective, the use of built-in CPU virtualization features to isolate hardware security functions and separate application runtime services from hardware control interfaces goes a long way toward assuring system robustness. Such design techniques eliminate commonly exploited threat vectors that result in security policy bypass, privilege escalation and loss of CPU control altogether.

The ability for software partitions to be fortified and controlled with greater fidelity at the hardware level aligns perfectly with FACE ideals. Figure 3 introduces the notion of a hardware partitioning segment fulfilled by a hypervisor to the FACE reference architecture. The depiction shows a hypervisor isolating two sets of software on two different CPU cores, with each set configured with FACE conformant components. Each set of software is granted greater partitioning properties over a single OS-hosted design in which the

device drivers and internal service are separated.

Conformance: An example

The fact that the FACE conformance certification process is conducted using an independent assessment is the best way to assure customers that a product conforms to the requirements found within the FACE Technical Standard. The answer to preventing the “what could go wrong” using the FACE standard comes down to assuring 100% conformance to its requirements. Otherwise, the potential strongly exists for reuse to be denied and integration costs to rise because an interface mismatch can occur.

Collins Aerospace is committed to FACE conformance and earned the industry’s first FACE conformance certification in 2016. The company has found that these certificates provide an outstanding marketing vehicle to show proof that it is an open system software provider that adheres to MOSA.

The Tactical Combat Training System (TCTS) Increment II program (Figure 4) is one important example of using open standards to provide multidomain live, virtual and constructive (LVC) training capabilities to modern warfighters. The underlying system – called the Joint Secure ACMI System (JSAS) – uses an open systems architecture leveraging FACE and other industry interface standards to enable interfacing with a variety of monitoring and debriefing systems.

Proof of FACE lies in its ability to win business

Mandatory FACE conformance requirements have flowed down for nearly every applicable military program since the publication of FACE 2.0.

Ultimately, the proof of the principles lies in the ability to win business through their application. That ability is ably demonstrated, in one instance, by the success of Collins Aerospace’s Tactical Combat Training System (TCTS) Increment II program, whose underlying system uses an open systems architecture incorporating FACE and other industry interface standards. ■

MOSA systems: The benefits of deploying a datacentric architecture

A Modular Open Systems Approach (MOSA) – the method recommended by the U.S. Department of Defense (DoD) for the implementation of open systems – uses a decoupled system architecture that enables components to be incrementally added, removed, or replaced throughout the life cycle of a platform, providing opportunities for enhanced competition and innovation.

The U.S. Department of Defense (DoD) recognizes the importance of data and considers data as a strategic resource. A datacentric architecture is uniquely able to accomplish this goal because it not only enables systems to be decoupled and independent from each other, but also focuses the systems on the data itself. This approach supports both MOSA [Modular Open Systems Approach] and DoD data strategies. A datacentric architecture makes data the common element for systems to act on and consume, while also producing data that other systems can use such as

uncrewed aircraft system (UAS) payloads generating ever increasing amounts of intelligence, surveillance, and reconnaissance (ISR) data.

A datacentric architecture can be achieved by using open standards, which are at the core of MOSA. Current DoD standards, including the Future Airborne Capability Environment (FACE) Technical Standard, already embrace a datacentric architecture by emphasizing the importance of data. For example, the FACE approach encourages the use of a data model and requires FACE Units of Conformance (UoCs) to have a well-defined data model that can provide the structure to communicate through the Transport Services Segment (TSS) of the FACE architecture.

A datacentric architecture is an excellent use case for a publish-subscribe architecture, based on the open Data Distribution Service (DDS) standard, which also emphasizes the importance of data. Individual systems declare the intent to subscribe to data or advertise the data they have to offer. The publish-subscribe protocol then

matches publishers and subscribers with each other and makes sure the data gets to the right place at the right time. New participants can join at runtime without the need for code modifications, enabling rapid updates and technology refreshes using the existing data architecture.

Datacentricity and the system

Most software developers and system architects take an application-focused view on defining systems. They start off with defining the applications which are needed in a system (e.g., a GUI, processing, and the like). The next step is defining what the interfaces should be, and what is needed by each application. The interfaces keep evolving as new functionality is added and in most cases requires additional information. However, what really matters is the data, not the application; the application is

simply a way to display the data of interest. The same data is as important if it is displayed in a different application. For example, revenue numbers can be viewed in Excel, Word, Notepad, Vi, etc. The way the application displays the data may make it easier for the user to understand; however, the data – and not the application – has the key information and not the application. The information is in the data. (Figure 1.)

In contrast, datacentricity puts data at the center of the architecture; in other words, data is the primary asset of the system. (Figure 2.)

Realizing the importance of data, FACE requires a data model which provides a standard method for defining the data format and meaning for information-sharing between software components (e.g., FACE Unit of Portability (UoP)). The FACE data

FIGURE 2 | A datacentric approach to architecture is shown.

architecture is a key component of the FACE approach and is essential to designing systems and developing interoperable UoPs.

The DoD is rapidly transitioning to a datacentric enterprise. Datacentricity enables decision dominance at the speed of war and supports DoD efforts such as Joint AllDomain Command and Control (JADC2) that integrates sensors to command and control (C2) to effector systems across different operational commands, from the tactical edge to the cloud. This aligns exactly with the DoD Data Strategy announced in September 2020 that directs DoD leaders to evolve all DoD assets into datacentric assets that treat data as a weapon system.

In a datacentric system, the design starts with the data model. What data do I need, and how will it be represented? Different components can access shared data and communicate through shared data. Access rules can be put in place so only allowed and authenticated users can access the data. Since the data scheme is defined and all applications act on the same data, integration of new components is minimal and in most cases no data transformation is required. An example of a datacentric architecture is a database architecture. A common database schema is created and accessed through a defined protocol. Another advantage of this approach is that there are no dependencies between applications as the applications do not directly communicate with each other. All communication is done through accessing (reading or writing) data.

For a real-time system, it is not practical to exchange data by writing and reading data into a central database. In addition to the latency, the database server would be a single point of failure. To facilitate communication in a real-time system, the DDS standard, managed by the Object Management Group (OMG), was developed. DDS not only

supports a datacentric architecture; it also uses a simple publish-subscribe paradigm. As was established earlier, a datacentric approach focuses on data and has a data model. DDS requires a data model and is aware of the data being exchanged. In addition, the publish-subscribe paradigm with the discovery feature allows new applications to subscribe or publish any of the data defined in the data model.

The benefit of the publish-subscribe system is that the application does not need to know where to send the information or from where to request the information. To illustrate this, look at a classic message system similar to email: As a participant, I must email a status report every week, I need to know whom to send it to, and I need to list all the recipients. If there is a new person who is also interested in the weekly status email, that person needs to let me know so I can add the address to the future status-report emails.

Publish-subscribe works more like social media, where I post my status and whoever follows me receives the update. If a new person is interested in the status, that person can follow (subscribe) to my status and automatically get the updates. I do not need to know how many followers I have. All I do is post (publish) my status update. DDS has another advantage: Since it is datacentric, I can apply filters on any of the data elements. Instead of getting a notification of every new status report, I now get updates only when a filtering criteria is met. Instead of getting every status report, I only get the status reports which have relevant information. The filter criteria can be changed at any point if the data of interest changes.

The Data Distribution Services (DDS) standard

Let’s take a closer look at DDS. The DDS standard is a set of standards which define the application API as well as the real-time publish-subscribe (RTPS) wire protocol that enables a transportagnostic, open standards-based capability to rapidly connect applications from a wide range of programming languages, operating systems, and computing platforms. DDS enables the user to separate transport from the application logic. The DDS standard currently includes the following:

› High-performance, scalable, secure, and datacentric publish-subscribe abstraction.

› Completely decentralized architecture with dynamic discovery service that automatically establishes communication between matching peers.

› Rich quality of service (QoS) characteristics for control over every aspect of data distribution, such as data availability, resource usage, reliability, and timing.

› Interoperable data sharing, platform-independent extensible data modeling, encoding, and representation.

› Recent extensions for remote procedure calls (RPC), security, resource-constrained devices, web integration, and OPC UA integration.

DDS provides data-sharing that is controlled by QoS policies. Applications communicate by publishing and subscribing to DDS topics identified by their topic name. Subscriptions can specify time and content filters and receive a subset of the data being published on the topic. Different DDS domains are completely independent of each other, as they do not share any data communication. In the case of UDP, this is achieved by using separate ports for each domain. There is no data-sharing across DDS domains. Figure 3 is an example of DDS communication using a single domain.

DDS participants can be on the same machine or across a network. In either case, the application uses the same DDS API for communications. Because there is no need to know or configure IP addresses or consider the differences in machine architectures, the process of adding additional communication participants on any operating system or hardware platform becomes an almost trivial task.

How DDS and datacentricity support MOSA

MOSA is a technical and business strategy for designing affordable and adaptable systems. The five principles of MOSA are:

1. Establish an enabling environment

2. Employ modular design

3. Designate key interfaces

4. Use open standards

5. Certify conformance

The first principle of establishing an enabling environment is really a business practice which supports the program manager in deploying MOSA throughout the acquisition life cycle.

MOSA requires a system architecture that allows several major system components at the appropriate level to be incrementally added, removed, or replaced throughout the life cycle of a major system platform, to afford opportunities for enhanced competition and innovation. Using a datacentric approach addresses principles two and three. A datacentric architecture inherently enables a module design as all components access a common set of data which also serves as the interface description. Creating a data model or using a standard data model is the foundation of a successful datacentric MOSA system. This can be a separate domain-specific data model or can be part of a specification (e.g., UMAA [Unmanned Maritime Autonomy Architecture] or ROS [Robot Operating System libraries]).

www.opengroup.org/face FACE Special Edition 2023 | 21
FIGURE 3 | A diagram shows the datacentric Publish-Subscribe approach.

Using open standards is another key principle. With open standards, application developers are not locked into a specific technology or vendor. The market decides which technologies are the most viable. Open standards establish protocols and building blocks that can help make applications more functional and interoperable which streamlines product development. Many of the open standards have multiple revisions and have improved from lessons learned over time. Using open standards is much more cost- and time-effective than new development. DDS is an example of an open standard that fits perfectly in many of the MOSA applications. The DDS standard has an active and vibrant community continuously working to extend its applicability. (Figure 4.) The DDS standard currently includes the following:

› Core specification (DDS, RTPS, DDS- XTypesTM, DDS-SECURITY)

› Language mappings

› APIs: C, C++, Java, and others

› Gateways (XRCE, Web, OPC)

DDS is also used in many other standards including FACE, UMAA, ROS, and GVA. Figure 5 shows some of the standards where DDS is used.

DDS use cases

DDS and RTPS packets are used for mission-critical applications, connecting embedded systems as a reliable communication layer between sensors, controllers, and actuators. DDS runs many of the most complex systems in the world: It powers the largest energy plants in North America, connects perception to control in autonomous vehicles, coordinates combat management in defense systems, drives a new generation of medical robotics, controls hyperloop and flying cars, provides 24/7 medical intelligence for hospital patients and emergency victims, and more.

At the TSOA-ID 2022 conference, RTI demonstrated interoperability between different native DDS applications (e.g., Unity and Epic Games Unreal Engine) and standards using DDS (e.g., FACE, ROS). The demonstration consists of two

drone simulators: one using the Unity gaming engine, and the other using the Epic Unreal Engine gaming engine. These drone flight simulators publish location, video, and lidar using the Sensor Open Systems Architecture (SOSA) Interaction Binding and publish data through a SOSA aligned plugin. The lidar data is displayed using the RVIZ, a ROS 2 application, while location is fed into different cockpit display systems (CDSs). Figure 6 shows the architecture of the demonstration. The integration of all those components was made possible by using a common data model. New components can easily be added, and variations of the demo have been demonstrated at different trade shows.

MOSA: No more vendor lock

MOSA recognized that to reduce cost, time to market, and to develop better, more flexible solutions, it must embrace open architectures. The era of black box and vendor-locked technologies has ended, and the industry must embrace open standards in all types of software ranging from commercial off-the-shelf to open source. MOSA is not just an

innovative idea, it is a legal requirement – specifically, Title 10 U.S. Code 2446a.(b), Sec 805 of DoD Acquisition Regulations – to achieve the development of affordable, adaptable systems.

It has been a few years since the DoD Data Strategy was created, and the DoD continuously makes strides toward its goal of transforming into a datacentric agency. To support that transition, new systems also need to embrace a datacentric strategy. Open standards such as DDS will become an essential part in supporting the DoD’s transition to a datacentric world. A datacentric open standard such as DDS enables the fundamental step for designing, developing, and deploying next-generation, distributed mission-critical systems and supports the MOSA principles of achieving lower life cycle costs in deployment and maintenance, faster time to market, and improved reliability during deployment in crewed and uncrewed systems. ■

LynxOS-178 is a native POSIX, hard real-time partitioning operating system developed and certified to FAA DO-178C DAL A safety standards. It is the only commercial off-the-shelf (COTS) OS to be awarded a Reusable Software Component (RSC) certificate from the FAA for reusability in DO-178C certification projects.

LynxOS-178 is the primary host for real-time POSIX and Future Airborne Capability Environment™ (FACE) Technical Standard applications within the LYNX MOSA.ic™ development and integration framework. LynxOS-178 native POSIX implementation satisfies the PSE 53/54 profiles for both dedicated and multi-purpose real-time as well as FACE™ applications.

LynxOS-178 has passed the conformance testing for version 3.1 of the FACE specification for the x86, Arm, and PowerPC platforms. It is based on open standards and is designed specifically to fulfill the stringent needs of multithread and multiprocess applications in safety-critical real-time systems, providing security and safety through strict, hardware-enforced isolation between real-time processes, applications, and the RTOS kernel services and drivers. Our partnership with Adacore/Ferrous brings a reliable Rust toolchain into the Lynx developer environment, which enables customers to create applications in Rust for deployment on LynxOS-178 and/or the Lynx Unikernel.

LynxOS-178 provides previously certified software and artifacts in order to fully satisfy, right out of the box, the DO-178C level A requirement that every line of software in the system be verified with Modified Condition/ Decision Coverage. The DO-178C certification process is so time- and laborintensive that vendors may experience an output of just 125 lines of code per man-month. Testing of complex code could quickly add up to millions of dollars.

LynxOS-178 RSC is more than just a set of DO-178C artifacts. The docu-

mentation set includes a detailed partitioning and interface analysis that focuses on time, space and resource partitioning as well as timing margin analysis so developers can allocate budgets to use operating system services. The set of RSC guidance documentation includes requirements, design data, test suites and coverage analysis to meet DO-178C requirements.

LynxOS-178 has been deployed in certified commercial and military avionics systems that have flown hundreds of millions of hours.

The FACE Approach

The Future Airborne Capability Environment™(FACE) Approach is a Government-industrydeveloped software standardand business strategy withthe

goals to:

• Increase the affordability of capabilities

• Improve time-to-field, delivering new capabilities to the warfighter faster

The FACE Approachintegratestechnical andbusiness practices thatestablish a standard commonoperatinn---..... environment to support portable capabilities across avionics systems.

The FACE Technical Standard defines the requirements for architectural segments and key interfaces that link thesegments together. This enables the reuse of capability-basedsoftware componentsacross different hardware computing environments.

The ideais to avoid "reinventing the wheel" for every new platform system. It also enables rapid replacement of older softwareand insertion with new andimproved capabilities throughout the system lifecycle. The FACE Approach is relevant to both enduring systems and future systems, including new system designs, system-level upgrades, and component upgrades.
