  MULTI-CASTING

Multi-casting is the method by which packets are sent to a 'host-group'. This group may consist of zero or more hosts identified by a single IP address. Due to the transmission methods of IP routing for a group of hosts, it is not guaranteed that every member in the group will recieve intact datagrams. As such delivery for multicast destinations is known as 'best-effort' reliability.

IP Multicasting is therefore a bandwidth conserving technology that reduces traffic by simultaneously delivering a single stream of information to thousands of recipients. It delivers to multiple receivers without adding any additional burden on the source oor the receivers whilst using the least network bandwidth. Multicast packets are replicated in the network by routers.
