摘要
面向可靠组播中的多媒体流传输业务,讨论了目前组播拥塞控制面临的主要挑战,提出了一种路由器辅助基于速率的组播拥塞控制算法。算法保证了多媒体业务的有效传输,很好地改善了丢失路径多样性问题。仿真表明,算法具有良好的公平性、有效性和可扩展性。
This paper discusses the main challenge of multieast congestion control and proposes a router-assisted rate-based congestion control algorithm for real-time multimedia streams in reliable multieast.The algorithm guarantees the efficiency of multimedia streams application in temporary congestion and improves the loss path muhiplieity problem.The results of the simulated experiments show that the algorithm has good fairness,friendliness and sealability.
