Multicasting. Multicast communications refers to one-to-many or many-to-many communications. . IP Multicasting refers to the implementation of multicast communication in the Internet. Multicast is driven by receivers: Receivers indicate interest in . Gossiping. Steve Ko. Computer Sciences and Engineering. University at Buffalo. Recap. Available copies replication?.

Switched . ethernet. is good. Besides switching needed to join even multiple classical . ethernet. networks. Routing is expensive, learning switches seem cheaper. Flooding in a network with a cycle of switches is bad (why?). n Models: Summary. Ken Birman. Cornell University. . CS5410 . Fall 2008. . Snapshot: Replication “models”. By now we’re starting to see that “replication” comes in many flavors. No model: UDP multicast (IPMC), Scalable Reliable Multicast, TCP. Often called “best effort” but not always clear what this really means. In practice, loss occurs on sockets, not network.
