目前，TCP/IP通信被限制为每个连接只有一条路径，但对等体之间往往存在多条路径。将这些多条路径同时用于TCP/IP会话将改善网络内的资源使用，并因此通过更高的吞吐量和改进的对网络故障的恢复能力来改善用户体验。多路径TCP提供了在对等设备之间同时使用多条路径的能力。本文档提供了一组对传统TCP的扩展，以支持多路径操作。该协议向应用程序提供与TCP相同类型的服务(即，可靠的字节流)，并且它提供在可能不相交的路径上建立和使用多个TCP流所必需的组件。本文档为互联网社区定义了一项实验协议。
TCP/IP communication is currently restricted to a single path per connection, yet multiple paths often exist between peers. The simultaneous use of these multiple paths for a TCP/IP session would improve resource usage within the network and, thus, improve user experience through higher throughput and improved resilience to network failure. Multipath TCP provides the ability to simultaneously use multiple paths between peers. This document presents a set of extensions to traditional TCP to support multipath operation. The protocol offers the same type of service to applications as TCP (i.e., reliable bytestream), and it provides the components necessary to establish and use multiple TCP flows across potentially disjoint paths. This document defines an Experimental Protocol for the Internet community.
