摘要
利用多宿主设备的多个接口实现多路径传输、获取更多的网络吞吐量是因特网协议研究的热点。IETF所关注的MPTCP协议是当前比较成熟、关键的多路径传输协议。为了测试MPTCP在当前已部署的网络环境中的性能,分别在本地测试床、Internet环境测试场景和大规模多宿主系统Nor Net测试床中对MPTCP多路径传输实际吞吐量性能进行了测试和分析,测试结果表明MPTCP相对TCP虽能获得吞吐量的提高,但在非相似带宽链路的场景中其性能仍然不完善,其路径管理和传输调度策略仍需要进一步改进。
Achieving multipath transport and getting more network throughput by using multiple interfaces of multi-homed device is a hot topic in Internet protocol. MPTCP is a mature and key protocol for multipath transmission, also in the focus of the IETF. This article presents the behaviors of MPTCP multipath transmission in the local test-bed scenario, Internet scenario and Nor Net test-bed scenario. Results show that MPTCP protocols can significantly increase throughput. Meanwhile its path management and scheduling strategy for transmission are still not perfect and need further improvement in dissimilar path scenario.
