Why Shaping Traffic at the Sender is Important

Chuck Meyer, Chief Technical Officer, Production

To manage this risk in advance, broadcasters should consider how the buffers in the switch work and ensure that data senders behave in such a way that the buffers never become too full. This practice is known as sender traffic shaping. To ensure pre-compensating for this adverse effect is efficiently applied to IP, broadcasters must follow one rule: the network must be designed and managed for the desired traffic load.

Shaping sender traffic is important for system reliability, and it is equally important to consider its impact for low latency and jitter in live production systems. To ensure the optimal workflow and performance, use the proposed SMPTE 2110-21 standard as a way to design the system, and then verify this, as well as system performance requirements, with your router vendor."
