Abstract:

Internet video playback consumes a lot of bandwidth.The multicast technology can reduce the bandwidth usage of video playback and the load of video servers.At present,only some expensive hardware routers have the function of multicast.This paper proposes a solution by using the rapid developing emerging technologies of virtualization and software routing to set up a multicast network consisting of multiple software routers on the virtual machine to build the multicast video server.The feasibility of the program is proved by testing the effect of the multicast network.
