多路径 TCP (MPTCP) 是 TCP 的新演进，它使单个 MPTCP 连接能够对应用程序透明地使用多个 TCP 子流。每个子流独立运行，允许在端点发生变化时保持连接；在动态网络中至关重要。区分拥塞延迟和切换引起的延迟是传输层协议忽略的一个重要区别。需要修改协议来缓解不断发展的移动文化中由切换引起的问题。在本文中，介绍了有关当前部署网络中传输层切换问题的研究结果。讨论了 MPTCP 作为解决切换和移动相关服务连续性问题的潜在解决方案。最后，设计并评估了一种切换感知的跨层辅助MPTCP（CLA-MPTCP）拥塞控制算法。
Multi-Path TCP (MPTCP) is a new evolution of TCP that enables a single MPTCP connection to use multiple TCP subflows transparently to applications. Each subflow runs independently allowing the connection to be maintained if endpoints change; essential in a dynamic network. Differentiating between congestion delay and delay due to handovers is an important distinction overlooked by transport layer protocols. Protocol modifications are needed to alleviate handoff induced issues in a growing mobile culture. In this article, findings are presented on transport layer handoff issues in currently deployed networks. MPTCP as a potential solution to addressing handoff- and mobility-related service continuity issues is discussed. Finally, a handoff-aware cross-layer assisted MPTCP (CLA-MPTCP) congestion control algorithm is designed and evaluated.
