摘要
分析了Padhye's TCP吞吐量模型存在的缺陷,提出一种新的基于动态TCP吞吐量模型的流媒体拥塞控制机制,它能够保证动态环境下的TCP友好性,并对网络状态的变化有很好的响应性。详细阐述了该拥塞机制的原理并给出了动态TCP模型的吞吐量公式。最后,通过NS模拟,验证了该拥塞机制的优越性。
The flaw of the Padhye's TCP throughput model used in this congestion control is analyzed and a novel TCP-friendly congestion control scheme for streaming based on dynamic TCP throughput model is proposed . The proposed scheme can ensure its TCP-friendliness in dynamic network condition and has prompt responsiveness to the change of network conditions. The principle of the proposed scheme is expatiated on and the equation of the dynamic TCP throughput model is given in this paper. In the end, the advantage of the scheme is validated by simulation in NS.
