摘要
多路径 TCP（MPTCP）是领先的传输层协议之一，可通过多路径传输提高网络性能。然而，由于链路拥塞，MPTCP 的吞吐量可能会下降，从而导致网络容量利用不足。我们为 MPTCP 提出了一种基于软件定义网络（SDN）的新链路拥塞检测方法，它能检测并绕开链路拥塞，从而实现稳定的 MPTCP 性能。测量结果表明，所提出的方案能最大限度地降低链路拥塞的影响，从而实现高效的数据包传输。此外，建议方案与 SDN 监控相结合，可根据建议的链路拥塞检测实现动态流量控制。
MPTCP-based link congestion detection and traffic control scheme in software-defined networks
Multipath TCP (MPTCP) is one of the leading transport layer protocols that enables multipath transmission to improve network performance. However, MPTCP can experience throughput degradation due to link congestion, which causes underutilizing of the network capacity. We proposed a new link congestion detection based on Software-Defined Networking (SDN) for MPTCP that detects and detours link congestion to achieve a stable MPTCP performance. Measurement results show that the proposed scheme enables efficient packet transmission by minimizing the effect of link congestion. Moreover, a combination of the proposed scheme and SDN monitoring enables dynamic traffic control based on the proposed link congestion detection.
