Abstract
Across the entire broadcast chain from production to distribution, real-time digital workflows are now commonly being distributed over Internet Protocol (IP) networks. Many deployments are leveraging IP multicast to optimise the delivery from a source to a set of diverse end points (receiver) such as video servers, mixers, quality control units, video monitoring, time & synchronisation slaves, etc. These devices require reliable and deterministic network behaviour to ensure an optimal operating environment. Technology developments in multicast-related protocols and architectures such as Source Specific Multicast, transport virtualisation, Fast Convergence, inline video monitoring metrics, combined with multicast hardware replication improvements in routers and switches, have significantly increased the reliability of the network layer transport for digital workflows. By preventing bandwidth duplication or centralised congestion points, reducing outage duration by using dual paths between source and receivers, combined with protocol, hardware, monitoring and security improvements, the overall reliability of IP multicast networks has dramatically increased in the last decade.
