本文介绍了可扩展可靠组播（SRM），一种用于轻量级会话和应用层分帧的可靠组播框架，该框架的算法高效，鲁棒，并且可以将web扩展到非常大的网络和非常大的会话，SRM框架已在wb中原型化，wb是一种分布式白板应用程序，已在全球范围内使用，会话范围从几到几百个参与者。本文描述了指导SRM设计的原则，包括IP组播组交付模型、端到端、基于接收器的可靠性模型和应用层帧协议模型。与单播通信一样，可靠的组播交付算法的性能取决于底层拓扑和操作环境，我们通过分析和仿真来研究这种依赖性。并演示了一种自适应算法，该算法使用先前丢失恢复事件的结果来调整用于未来丢失恢复的控制参数。通过自适应算法，我们的可靠多播传输算法在广泛的底层拓扑上提供了良好的性能。
This paper describes Scalable Reliable Multicast (SRM), a reliable multicast framework for light-weight sessions and application level framing, The algorithms of this framework are efficient, robust, and scale web to both very large networks and very large sessions, The SRM framework has been prototyped in wb, a distributed whiteboard application, which has been used on a global scale with sessions ranging from a few to a few hundred participants, The paper describes the principles that have guided the SRM design, including the IP multicast group delivery model, an end-to-end, receiver-based model of reliability, and the application level framing protocol model, As with unicast communications, the performance of a reliable multicast delivery algorithm depends on the underlying topology and operational environment, We investigate that dependence via analysis and simulation, and demonstrate an adaptive algorithm that uses the results of previous loss recovery events to adapt the control parameters used for future loss recovery, With the adaptive algorithm, our reliable multicast delivery algorithm provides good performance over a wide range of underlying topologies.
