Dynamic rate control mechanism for large scale sessions

The network environments of the Internet Multicast session performance are various. The size of Internet community gets bigger and bigger and the variety gets deepening. This paper suggests to build a barrier on every link to restrict the amount of data flowing into the network. Each link has threshold value to specify the requirement for the packets. Multimedia stream is encoded into multiple layers and each layer has its own TTL value. The lowest layer has the largest TTL and the highest layer has the smallest TTL. The threshold is modified according to the traffic of the network and that of the link. It helps the network and the links avoid congestion and make full use of available network capacity
