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. 2. 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 . Junxiao. Shi . 2015-02-11. Problem. Two routers and a laptop is in the same multicast group or broadcast media.. The laptop sends an Interest to the multicast group, which is forwarded by both routers to the Internet.. Qi Huang. CS6410 2009 FA. 10/29/09. Basic idea: same data needs to reach a set of multiple receivers. Application:. What is multicast?. How about using . unicast. ?. Sender’s overhead grows linearly with the group size. draft-schmidt-multimob-fmipv6-pfmipv6-multicast-04. Thomas C. Schmidt, Matthias Wählisch, Rajeev Koodli, Gorry Fairhurst. Motivation of this work. Context transfer is mainly an issue between Access Routers . Dmitry Basin. Ken . Birman. Idit. . Keidar. Ymir. . Vigfusson. LADIS 2010. Multicast is Important . 2. Replication is used in data centers and clouds:. to provision financial servers of read-mostly requests. 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?). Ken Birman. Cornell University. CS5410 Fall 2008. . Mission Impossible…. Today, multicast is . persona non-grata. in most cloud settings. Amazon’s stories of their experience with violent load oscillations has frightened most people in the industry. 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. SRM uses . Presented by Tom . Ternquist. CS 6410. 10/28/10.
