Using PTP for Time & Frequency in Broadcast Applications - Part 3: Network design for PTP

This third part of the series of articles focuses on the IP network design specifics or the transport of PTP over broadcast networks.

As described in the previous parts of this series, the IEEE 1588 Precision Time Protocol (PTP) plays a significant role in new systems designed around an IP centric transport model, especially those that are based on the SMPTE ST 2110 document series. 

Since there are several different requirements linked to content production, infrastructure topologies may vary significantly from one use case to another. Therefore, the network requirements are addressed as a series of parameters to be taken into consideration during the design phase. This approach will allow for tuning the network model to best fulfil the use case requirements.
