ServiceOn Network Manager Network Management Layer
General
Key benefits
The ServiceOn Network Management system is a multi-technology system for SDH and PDH enabled networks. It integrates element management data to provide a clear network view and allows total network control. Able to support to support huge networks from a single platform it consolidates a number of ServiceOn Element Management systems into a single seamless network view.

Faster customer service provisioning Service Level Agreement support including performance reports Resilient server platform solutions available Reduced network operating costs and increased service availability. Automated trail routing and path restoration. Network fault and performance data correlated to affected services.
Solution Architecture
Scalability
The ServiceOn NMS is the software platform supporting network wide management of the Microwave and Optical Broadband product set carrying SDH, PDH and Ethernet services. It supports end to end circuit provisioning and management for services from 2Mbit/s to 40Gbit/s from a single screen. With a comprehensive feature set enabling configuration of network resources through to analysis of fault and performance data against services, it aids the operator in fast efficient provisioning and rapid fault resolution minimizing down time and loss of revenue.
Ericsson can tailor the solution to meet the operator’s requirements for both small and large networks. For instance, for small network configurations, the ServiceOn Network Manager can be hosted on the same platform as the ServiceOn Microwave or ServiceOn Optical Management Systems.
Based on a modular software design and employing scalable server platforms the ServiceOn Network Manager can cost-effectively from tens to thousands of network elements. As a scaleable solution, operators can deploy the system in a cost-effective way, minimizing first-in costs and then growing with the network. The ServiceOn Network manager provides a range of interfaces enabling external applications access to network and element information. Ericsson has extensive competence in the integration of the ServiceOn portfolio with CoTs products such as IBM with Netcool, Cramer, Axiom, Syndesis, Metasolv, HP Temip, Metrica and customer specific management applications.

With larger networks, the Network Management system is hosted on its own server linked by the Ethernet management DCN to multiple Element Management platforms. In this way the ServiceOn Management solution can grow to support large network deployments, but is still able to provide an integrated whole network view from a single network management screen. The software operates on both Linux and Unix based hardware platforms enabling very cost effective management solutions to be designed. The ServiceOn Network Manager offers future extendibility to cope with the challenges of multitechnology networks by adding support for products from the Ericsson Access portfolios.

System Description
Features
The ServiceOn Network Manager application is hosted on selected platforms from the HP ProLiant and HP Itanium server families.
Service Provisioning Automatic trail routing is one of the key features provided for service provisioning. From the GUI operators use the icons and pull down menus to quickly and easily configure new services. Automatic routing is supported by optimized routing features for Optical and Microwave subnetworks ensuring the most efficient use of the available resources. This capability is also available to external provisioning systems over the northbound interface. External planning systems can extract detailed network level inventory data on network topology, circuits and connectivity through the network information interface.
High-availability solutions for are supported at platform level by the use of disk mirroring and duplication of hardware such as LAN and disk interfaces. Application level protection is supported by use multiple platforms and Geographical redundancy software for Warm standby operation. Itanium based solutions can also be protected through the use of the HP ServiceGuard software for hot standby solutions. The Warm and Hot standby solutions can be combined to offer increased availability. User access is supported through the use of Windows based PC platforms and suitable access software. The user interaction is supported through a windows based GUI where menus and dialog boxes assist the operator in carrying out tasks. The GUI features a consistent style across the managed technologies, providing access to the full range of element and network level features including: Fault, Configuration, Performance and Security management. A continuing program of software development ensures that the ServiceOn Network Management system features are enhanced to keep pace with technology and operational requirements.
Alarm Reporting The ServiceOn Network Management System maps alarms to customer circuits, allowing operators to quickly locate service affecting problems and associated network element or link failures. The real-time alarm monitor presents a scrolling list of alarms as they are raised and cleared enabling instant tracking of network problems. The alarm and fault information can be exported to external applications via the northbound interfaces. Architecture The Network management system stores and displays performance statistics. The graphical display of the service performance enables the network operator to quickly understand the status of a given customers quality of service.
Data Summary General The ServiceOn Network Manager is designed to meet the appropriate sections of ITU-T recommendations M.3010 and M.3400. Fault Management Provides effective surveillance of network-wide alarms: • Real-time alarm monitoring • Alarm supervision • Alarm correlation and filtering • Alarm threshold settings • Alarm reports Configuration Management Enables the user to install and configure network elements, to create traffic paths across the network and dynamically protect services: • Provision and configure elements and subnetworks • Create customer services • Separate optimized Auto-routing engines for: o Optical Networks o Microwave Networks • Protect SDH and WDM circuits, rings and sections • Control service restoration features Performance Management • Performance management in accordance with ITU-T G.826 • Performance reports from the network can be enabled to provide 15-minute and 24hour reports • Performance monitoring and control at element and network level • Performance data analysis and display Security management Restricts access to the network management system, as determined by the system administrator. • User name and password • Defined user profiles • Domain partitions
External Interfaces Provides a number of interfaces to export data to service level systems: •
•
Practical service-to-business interface (CORBA)-enabling an external system to provision circuits that can be scheduled manually or automatically. Export of service-affecting fault data. TMF 814 conformant interface supporting: o Element and Network level fault management o Element and Network level configuration management o Scheduling of performance data o Retrieval of performance data
