RESEARCH ON A RELIABLE AND SCALABLE MULTICAST CONTROL MECHANISM

Reliable and scalable multicast is an active research field of multicast in recent years. A hypercube based reliable ＆ scalable multicast control mechanism is presented to solve the contradiction problem of multicast reliability and related scalability, which combines the hypercube geometric character of multicast reliable solution and the localization of multicast scalable solution. The mechanism is implemented by embedding the 1 dimension tree topology into n dimension hypercube topology and applying the local ARQ recovery to the hypercube topology. The experiments and tests are based on the MS Windows platform and 100M Ethernet LAN. According to the theory analysis and experiment results, the hypercube based reliable ＆ scalable mechanism shows efficient reliability and high scalability （the reliablility will increase with the scalability of node numbers in the hypercube,which can achieve over 90% reliability with only 4 nodes.）, which can fulfil the requirement of reliable ＆ scalable multicast in different network environments.
