适用于分布交互仿真的分布式可靠多播协议

Distributed Reliable Multicast for Distributed Interactive Simulation

在大规模分布式应用中,可靠的多播协议是非常重要的。这些应用需要通信协议支持:广泛的数据分布、及时的报文丢失检测和恢复、低延迟的报文传输、最小的报文标头以及细粒度的多播分组。迄今为止,很少有协议能完全支持以上特性。本文介绍了分布式可靠多播协议,论述并评估了使用该协议支持高性能仿真程序的优化方法,最后讨论了如何把该协议移植到更广泛的网络应用。

Reliable multicast communication is important in large-scale distributed applications. To date, proposed protocols have not supported these applications' requirements, which include wide-area data distribution, low-latency packet loss detection and recovery, and minimal data and management over-head within fine-grained multicast groups, each containing a single data source. In this paper, we introduce the notion of distributed reliable multicast communication, and we describe and evaluate a collection of log-based receiver reliable multicast optimizations. We argue that these techniques provide value to a broader range of applications and that the receiver-reliable model is an appropriate one for communication in general.
