Abstract:
Multicast is an efficient technique for point-to-multipoint (P2M) and multipoint-to-multipoint (M2M) communications because it exploits a tree, instead of disjoint paths, in the routing of group traffic. Current multicast standard on Internet, i.e., PIM-SM, employs a shortest-path tree to connect the clients in a multicast group. Traffic engineering is difficult to be supported in a shortest-path tree due to the fixed routing of the tree. With the emergence of Software-Defined Networks (SDN), flexible routing for traffic engineering now becomes promising, but at the same time the scalability problem appears to be the major stumbling block during the deployment since the traffic is difficult to be aggregated. In this talk, we will first present the scalabilityand traffic engineering problems for multicast and then introduce our approximation algorithms to solve the above problems efficiently and effectively. Implementation result on Youtube multicast traffic engineering in SDN will also be presented.
