基于多穴主机的延迟探测算法的仿真研究

Simulation Study on Delay Probe Algorithm for Multihomed Host

通过对单路径传输的缺点和随机多路径传输的不足的研究,提出了一个针对多穴主机的基于延时探测的网络层并发多路径传输算法,此算法能够动态适应链路性能的变化并且可以充分利用多个可用路径进行并发传输。NS2仿真实验表明,本算法获得了合理的吞吐量,延时和抖动性能。

Based on the comparison with conventional single path transmission and random CMP （Concurrent Multi-Path） transmission, a novel Delay Probe Transmission （DPT） algorithm in network layer for multihomed host was proposed, and this algorithm can adapt to the changing of link performance dynamically and makes full use of multiple paths to transmit simultaneously. NS2 simulations prove that DPT algorithm obtains reasonable performances of throughput, delay and jitter.
