摘要： 目前针对多路径传输控制协议(MPTCP)算法的评估多基于仿真环境,无法有效验证其在实际环境中的性能。为此,根据MPTCP的约束原则建立基于真实环境的实验平台,实现机会相关增长算法(OLIA)、平衡连接适应算法(Balia)、多路径TCP Veno算法(MPVeno)和加权Vegas算法(wVegas),并设计多种实验场景验证这4种拥塞控制算法在吞吐量、负载均衡和公平性方面的性能。实验结果表明,MPVeno的吞吐量性能最优,在子流链路拥塞状况不同时能更有效地利用网络资源,而Balia和wVegas则比MPVeno和OLIA表现出更好的公平性。

Abstract: As existing approaches for verifying Multipath Transmission Control Protocol(MPTCP) performance are based on simulation environment,which cannot effectively verify the performance of MPTCP in realistic network,an experimental platform is constructed in this paper based on real network environment according to the constraint principles of MPTCP.Moreover,it implements OLIA,Balia,MPVeno and wVegas and conducts a variety of experiments scenarios based on the proposed platform to evaluate the performance of the above-mentioned four congestion control algorithms in throughput,load balance and fairness.Experimental results show that,MPVeno performs best in throughout.And with different subflow link congestion,MPVeno can acheive more effective usage of network source.As for the fairness index,Balia and wVegas perform better than MPVeno and OLIA.

Key words: Multipath(MPTCP), experimental platform, congestion control algorithm, throughput, load balance, fairness
