摘要
首先阐述了TFRC算法的基本机制,并分析了TFRC算法在VoIP应用模式下产生的问题,提出利用增强虚拟包方法修改丢失事件率的计算,同时在算法中考虑包头对小包分组的影响,以消除原有方法的不适用性。最后,通过ns-2仿真实验表明了改进算法的有效性。
This paper illuminates the basic mechanism of TFRC algorithm. Then, it studies the problem of TFRC algorithm for VoIP application mode, and provides a new method of computing loss event rate and considering the effect of packet overhead in small packet for applicability. At last, an experiment of simulation on re-2 verifies the new algorithm.
