TCP传输层协议专为在发送方和接收方之间通过一条路径的连接而设计。但是，在一些环境中，一个连接可以同时使用多条路径。我们考虑支持在多条路径上运行的条带连接的问题。我们提出了一种端到端的传输层协议，称为pTCP(并行TCP)，它允许连接享受由多条路径提供的聚合带宽，而不考虑路径的单独特征。通过在三种不同环境中的实例化，我们证明了pTCP可以具有不同的应用范围：(A)多宿主移动主机上的带宽聚合；(B)使用纯端到端机制的服务区分；(C)基于端系统的网络条带化。在每一种应用中，我们通过仿真结果展示了pTCP的适用性以及它与现有方法的有效性比较。
The TCP transport layer protocol is designed for connections that traverse a single path between the sender and receiver. However there are several environments in which multiple paths can be used by a connection simultaneously. We consider the problem of supporting striped connections that operate over multiple paths. We propose an end-to-end transport layer protocol called pTCP (parallel TCP) that allows connections to enjoy the aggregate bandwidths offered by the multiple paths, irrespective of the individual characteristics of the paths. We show that pTCP can have a varied range of applications through instantiations in three different environments: (a) bandwidth aggregation on multi-homed mobile hosts; (b) service differentiation using purely end-to-end mechanisms; (c) end-systems based network striping. In each of the applications, we demonstrate the applicability of pTCP and how its efficacy compares with existing approaches through simulation results.
