PPT-Multicast

Qi Huang CS6410 2009 FA 102909 Basic idea same data needs to reach a set of multiple receivers Application What is multicast How about using unicast Senders overhead grows linearly with the group size. Multicast. . is the delivery of a message . to . a group of . receivers . simultaneously in a single transmission from the . source. The source sends a . message to a group. The message then is delivered to all members of the group. Gossiping. Steve Ko. Computer Sciences and Engineering. University at Buffalo. Recall: Passive Replication.
