A Patchwork of Multicast . Regions. Pub/sub transport. Pub/sub over WAN has plethora of modern uses. 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. Recap. Consistency models. Linearizability. Sequential consistency. Causal consistency. Eventual consistency. Depending on application scenarios, one consistency model makes more sense that others.. 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.. WiMAX. Networks. Guan-. Hsiung. . Liaw. , Yu-. Ren. . Shen. , Chia-Ho Lee. I-. Shou.

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?). Reliability. How do I answer these questions?. i.e. How reliable is this source ....?. Balance. Most sources chosen are reliable in some ways but not others.. Comments on origin. Who produced it? In what circumstance? For what purpose? Did they have a motive to mislead? How might this affect reliability?. Piyush Harsh & Richard Newman. Why do we need multicast!. No Universal Deployment? . Text. Text. Text. Text. IP Multicast has been around for a long time. It is just not used much! Why?. Why do we need a multicast session directory?. Reliable Sources = TRUSTWORTHY SOURCES. Written by experts in that particular field. Unreliable Sources = SOURCES THAT CAN BE ALTERED BY ANYONE . sources, such as Wikipedia, are not reliable because the authors may not have a thorough knowledge or full understanding of a topic.
