Adaptive CBT/Anycast routing algorithm for multimedia traffic overload

Abstract

According to the social demand to the expansion of internet use and construction of ultrahigh speed network, the realtime and the maximized capacity multimedia data service gets exceeding the infra level of communication. As a response to the communication condition, multicast service provides effective use from various resources and corresponds actively to high-speed data transmission. For these reasons, multicast service is considered as a major internet solution for the next generation. Thus in this study, various multicast routing methods are proposed and an analysis for CBT routing method based on CBT routing protocol from the existing multicast routing protocol is made. As a result, there happens traffic congestion to a core router because of structure problem of CBT protocol, thus performance of the whole routing declines as a consequence. The AIMD (Additive Increase Multiple Decrease) algorism applied Anycast routing method that is suitable for traffic dispersion in high bandwidth according to increment of traffic load from CBT Shared Tree Routing Method is strongly suggested in this thesis. © Springer-Verlag Berlin Heidelberg 2004.
