| 摘 要： | 针对当前多媒体流分层组播拥塞控制方案的不足,提出一种改进的接收者驱动的分层组播拥塞控制算法,并给出了详细的设计方案。算法借助AIMD算法具有的良好TCP兼容性保证组播流与TCP流的友好性;利用基于历史记录动态调整接收端加入某层等待时间的策略解决因过多失败的“加入”尝试带来的网络拥塞和振荡问题。通过实验证实了算法的有效性。

| Abstract: | Due to shortcomings of current congestion control for multimedia layered multicast,an improved receiver-based congestion control algorithm for multimedia layered multicast is presented and discussed in detail.The algorithm insures TCP-friendliness between multicast and TCP by making use of the AIMD algorithm,which is proved to have good TCP-compatibility.The algorithm avoids the network congestion and vibration due to high frequency of "add" test by choosing the best time to begin the "add" test.Experimental results show that this algorithm can achieve good result. |
