Based On The Tree Priority Application Layer Multicast Technology

Because of the few deployment of IP multicast in the Internet today,some researchers propose a new approach,Application Layer Multicast,to implement wide-area multicast services.This paper introduce Multicast and Application Layer Multicast technology .In this paper, a comprehensive survey on multicast arithmetics and schemes is given, the advantages and application range of these arithmetics or schemes are discussed respectively, also the shortcomings and problems existed are anatomized in depth, and then a comprehensive comparison is given. Based on these, This paper have proposed to be FEC foundation -based tree Application Layer Multicas scheme.This kind of scheme can solve reliability problems and meet delay time, shake request higher demand to network.
