Broadcast media transport facts Some challenges Exceptionally dynamic and scalable architecture needed Mix of very high and low bitrate flows Thousands of multicast flows needing to be live-switched PTP is mission critical Realtime audio/video for TV production Realtime audio for Radio production Playout File based applications Office applications Management Data Center applications Wide area networking …. Which applications can run on the same network? Enterprise & broadcast networks are different {F5AB1C69-6EDB-4FF4-983F-18BD219EF322} Enterprise networks Live broadcast networks Payload Data Video + audio + data Streams Mostly < 10Mbps Up to 12Gbps (4K video), many over 1.5Gbps Access interface 1Gbps 10/25Gbps Connection Client-server Peer-to-peer Transmission Unicast Multicast (> 10,000 flows) Profile Variable and bursty Constant Protocol TCP UDP Timing Often not required PTP (media flow synchronization) is mission critical Architecture options Studio Control room Data Center Studio Advantages: Similar to traditional MCR Non-blocking network No signal routing overhead No SDN / Broadcast Controller Challenges: Fiber management Redundancy must be handled by edge devices Centralized Resilient (Monolithic) Architecture options Advantages: Similar to traditional MCR Simple signal routing Challenges: No signal aggregation Fiber management Expensive for low bandwidth ports Tie-line management Redundancy must be handled by edge devices 9/11/2022 12 Dual Star (Red-blue network) Architecture options Advantages: Signal aggregation at the Leaf Simpler fiber management Cost effective edge ports for all bandwidths Built-in network redundancy (red/blue per stream) No endpoints blocked due to loss of single Spine Challenges: Blocking/Non-blocking depends on Utilization of Leaf-Spine links More complex signal routing Scalability dependent on amount of Uplink interfaces on Leaf 9/11/2022 13 Studio Control room Data Center Studio Architecture options True Spine-Leaf (Purple network) style.visibility style.visibility Options for traffic control Automatically routed IP networks Routing intelligence is built in to the network components Software Defined Networking Routing intelligence is centralized Choosing the right switch depends on the required combination of features Confidential A few examples of features to consider ( although not all strictly required for 2110): Any Questions?
