Questions tagged [multicast]
Multicast is the mechanism using which data traffic is reduced thoughout the network if a certain number of receivers are interested in the same data from the same source. This increases the efficiency of the network as less packets needs to be processed by the intermediate routers in the network. An inverted(spanning)tree like traffic path is formed for multicast data. This ensures that packets are replicated only when necessary.
