摘　　要：保证组播通信的可靠性是许多Internet上的组播应用的前提。针对IP组播在Internet中难以规模化部署的现状,提出了一种使用组播网关将IP组播岛与应用层组播(ALM)区域连接起来的可靠组播(RM)体系结构,对组标识、组播网关、组管理、差错控制和拥塞控制等关键问题给出了解决方案,并设计了组播网关竞争算法。该结构能够屏蔽底层组播技术差异,从而支持Internet上统一化的可靠组播服务部署。Guaranteeing the reliability of muhicast communication is the premise of many applications based on muhicast in Internet. Since it was difficult to deploy IP multicast on a large scale in Internet, the authors presented a Rehable Multicast （RM） architecture, which utilized multicast gateways to interconnect IP muhicast islands and Application Layer Multicast （ALM） domain. Solutions to key points in the architecture, such as group identification, muhicast gateway, group management, error control, and congestion control were also proposed. At the same time, a competitive algorithm for muhicast gateway was designed. This architecture could shield the difference existing in underlying multicast techniques and thereby support uniform deployment of reliable muhicast services in Internet.
