If your CCTV system uses multicast transmission over a redundant ring, then even if your ring redundancy protocol is able to activate backup paths in a fraction of a second when a disconnection occurs, it could still take more than 2 minutes for your multicast video streams to recover. This is because a number of different protocols—including IGMP (Internet Group Management Protocol) and PIM-DM (Protocol Independent Multicast - Dense Mode)—are implemented to transmit your video packets around the network, and these standard protocols are not designed for mission-critical applications. In this white paper, we show how implementing an appropriate non-standard proprietary protocol can optimize your network for video stream transmission, and in this way overcome IGMP’s sluggishness.
