摘要:

多播通信已经成为可缩放RT-DVS的一个重要支撑技术。针对IP多播部署的局限性和现有应用层多播系统的不足,本文提出了适用于分布式实时仿真的应用层多播系统DVSCast 。DVSCast综合考虑了广域网组通信中的可靠性、时延争端到端的流量控制等需求,在层叠网路由算法、可靠多播和端到端的拥塞控制方面具有良好的可伸缩性,可支持大规模组应用。

关键词: 应用层多播 可靠多播 端到端拥塞控制 分布式实时仿真

Abstract:

Multicasting is playing an important role in scalable applications of RT-DVS. Due to the limitations of the deployment of Ip multicast and the shortco mings of current overlay multicast solutions, this paper presents aaccount Internet-wide QoSs such as reliability, latency, and end-to-end flow control. DVSCast is more scalable in overlay routing, reliable multicastin , and end-to-end congestion control environments, and it can support large-scale group applications.
