组播拥塞控制策略设计与仿真研究

组播是一种高效率的点对多通信方式,在过去几年中组播传输机制己经成为一个活跃的研究领域。针对组播在Internet上进行大规模应用所面临的拥塞控制问题,将主动网络的技术应用到组播拥塞控制中,提出了通过主动节点主动检测拥塞和调整发送速率,实施hop-by-hop的拥塞控制的"主动"式的拥塞控制策略。在NS2平台上进行了大量网络仿真分析表明:该策略不仅对组播通信具有良好的拥塞控制能力,而且具有很好TCP友好性。

Design and simulation of multicast congestion-control strategy

Multicast is an efficient one-to-many communication method.In the past few years,the research on multicast transport mechanisms has been a hot topic.Aiming at the problem of congestion control when multicast is widely applied in Internet,the active network technology was applied to the multicast congestion-control strategy.When the active node detects congestion,it changes the send-rate and takes the congestion control hop-by-hop.Simulation results in NS2 show that the strategy has a good ability to control...
