摘要 提出了一种新的适用于分层多播拥塞控制方案中的往返时间(RTT)估算方法。该估算方法中,分层多播会话中未被抑制的接收者进行RTT测量,被抑制接收者进行单向延时测量来估算RTT值,同时该方法采用优先级因子将经常被抑制的接收者和具有较大RTT的接收者考虑在内。仿真结果表明该算法是可行的。 A new RTT(Round Trip Time) estimation algorithm for layered multicast congestion control is presented. Non-suppressed receivers in layered multicast session use round trip estimation to get an accurate RTr, suppressed receivers use one-way measurement to get an estimation of RTT, and the algorithm takes the frequently suppressed receivers and receivers with large RTT into consideration using a priority factor. Simulation results show that this algorithm is feasible.
