FACTORS TO CONSIDER WHILE DESIGNING AN IP MEDIA FABRIC
FOCUS AREAS SDI vs IP Legacy SDI Constraints IP Core Topology System Documenta2on Op2cs
SDI vs IP SDI • • • •
Determinis2c Latency Reliable, Fixed Bandwidth One Cable = One Signal Rigid Circuit Provisioning
• Large Physical Footprint • Logical Topology IS Reflec2ve of Physical Topology • Requires Specialized Hardware to Interface with COTS
IP • • • •
Non-‐determinis2c Latency SoPware Provisioned Bandwidth One Cable = Many Signals Agile Circuit Provisioning
• Lightweight Physical Footprint • Logical Topology NOT Reflec2ve of Physical Topology • Na2ve Compa2bility with COTS*
Legacy SDI Constraints Monitors Set Technology A/V Graphics Master Control External Feeds
IP Core Topology Non-‐blocking and Blocking Architectures Centralized Model Distributed Model Workgroup Model Diagnos2cs
System Documentation Network Topology Endpoint Inventory Switch Port Alloca2ons IP Address Assignments Source Maps Audio Maps Network Address Transla2on (NAT)
Optics Mul2mode (OM4) or Singlemode (OS2) MPO and LC PC and APC SFP, SFP+, and QSFP Ac2ve Op2cal Cables (AOC) Twinaxial Cables
