PPT-Multicast in the Data Center Overview

Mike McBride Helen Lui IETF 84 Vancouver July 2012 m boned charter Receive regular reports on the current state of the deployment of multicast technology Create practice and experience documents that capture the experience of those who have deployed and are deploying various multicast technologies. 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.. Junxiao. Shi . 2015-02-11. Problem. Two routers and a laptop is in the same multicast group or broadcast media..
