What is Multicast and how does it work?

Multicast is an IP technology that allows for streams of data to be sent efficiently from one source to many destinations. Instead of setting up separate unicast sessions for each destination, packets are replicated at router hops where the paths to different destinations diverge. e-Watch can use multicast to efficiently route video streams to multiple viewing stations.
