How multicast protocol works

Question

Explain how the multicast protocol works.

Answer 1

Multicast protocol delivers a single message to multiple machines. One packet from the source is replicated and sent to destination. Each and every multicast message needs a multi case group. The group states the addresses which will obtain the message. The group is stated by the class D address. Various routing protocols are employed to determine the multicast groups and make routes for them. Distance Vector Multicast protocol is one of the example. The receiver, to whom the multicast packet is sent to, requires to ‘join’ the group. Joining the class is enabled and managed by IGMP. Multicast routers are employed to transmit messages from one network to the other.
