Multicast Congestion Control Based on Multi Token Barrels

IP multicast is an effective data transmission,over the past few years,the multicast transmission mechanism has become an active area of research.However,it is very difficult to realise reliability and to achieve in multicast congestion because of its characteristics,multicast congestion control issues have not been able to get a good solution,it has become a bottleneck in its development.The increasing deterioration of the UDP data stream aggravates the ability of TCP congestion control,and it is one of the reasons to cause high packet loss rate.It presents a way to assign a fixed IP on the LAN bandwidth expansion token bucket algorithm,extends the number of token bucket,a token bucket control of an IP,eliminating the shortcomings of shared bandwidth,and through the design of circuits,modeling and simulation results show it can control the access of multicast and ensure the Qos of network and the design of the circuit occupies less hardware resources,which can be used in high speed circuits.
