Networking - Describe how the multicast protocol works

Describe how the multicast protocol works.

Multicast protocol or Internet protocol delivers a singles message to multiple machines. One packet from the source is replicated and sent to the destination. Every multicast message requires a multi case group. The group defines the addresses which will receive the message. The group is defined by the class D address. Different routing protocols are used to find the multicast groups and build routes for them. Distance Vector Multicast protocol is one of them. The receiver, to whom the multicast packet is sent to, needs to ‘join’ the group. Joining the group is enabled and managed by IGMP. Multicast routers are used to transmit the messages from one network to another.

Describe how to control the scope of multicast transmissions - Controlling the scope of multicast transmission restricts the range of group members. TTL (Time To Live) is one of the mechanisms to limit the scope.........
