    IP protocols have been used to distribute compressed media over pri-vate and public networks for a number of years. Recently the broadcast sector has started to adopt IP technologies to transport real time media within and be-tween their facilities during production. However, the high bitrate of uncom-pressed media and its sensitivity to latency and timing variations requires care-ful design of the network in order to maintain quality of service. Connectionless protocols are commonly used, which means that packet loss is of particular concern and redundant paths must be provisioned with mechanisms to switch between them.
    This project develops and critically analyses a method for measuring the effec-tiveness of first hop redundancy protocols for broadcast video production net-works. The aim extends previous work [1] to recommend particular configura-tions to optimise networks and to provide a method that broadcast engineers can use to verify performance.
    Cisco’s HSRP is recommended with static routes configured for redundant paths. It is recommended that the network is tested using a synthetic RTP stream with a low complexity packet sniffer and NICs with hardware timestamps. Further work is identified including ways to improve the accuracy of the results and to consider the impact of more complex networks.
