PPT-1 Multicast Routing

2 Multicasting Multicast communications refers to onetomany or manytomany communications IP Multicasting refers to the implementation of multicast communication in the Internet Multicast is driven by receivers Receivers indicate interest in . and . multicast. . routing. A superb presentation from . Joakim Lundmark and Martin Neuman. What. is . broadcasting. and multicasting?. Broadcasting. Send. to . every. . user. in a . network. 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.

Multiple tunnels terminate at MAG, possibly transporting duplicate traffic. Inherent to the PMIP base solution. The Story So Far. 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?).
