In recent years, network transmission carries big data of various types and sizes, which often have different transmission requirements. Transmission of data brings challenges to traditional transport layer protocols; meanwhile, performance improvements at endpoints and networks provide opportunities for new transport protocol design. Among the new designed transport layer protocols, multipath TCP is a promising one that provides better performance with multiple paths transmitting data simultaneously. However, when dealing with different types and sizes of data, MPTCP does not always work well, as all data streams are processed based on the same transmission strategy, which is simple but not always optimal. To fill this gap, in this article, we first give optimal strategies for different data flows, and propose a cross-layer solution for MPTCP, named FSA-MPTCP, to automatically provide flexible and optimal transmission strategies for different data flows. Finally, we conduct some experiments, and the results show that FSAMPTCP adaptively provides better performance for different kinds of flows.

MPTCP满足大数据：针对各种数据流定制传输策略

近年来，网络传输承载着各种类型和大小的大数据，这些数据通常具有不同的传输要求。数据传输给传统的传输层协议带来了挑战。同时，端点和网络的性能改进为新的传输协议设计提供了机会。在新设计的传输层协议中，多路径TCP是一种很有前途的协议，它可以通过多路径同时传输数据来提供更好的性能。但是，当处理不同类型和大小的数据时，MPTCP并不总是能正常工作，因为所有数据流都是基于相同的传输策略进行处理的，这很简单，但并不总是最佳的。为了填补这一空白，在本文中，我们首先针对不同的数据流提供了最佳策略，并提出了MPTCP的跨层解决方案，名为FSA-MPTCP的应用程序，可以为不同的数据流自动提供灵活，最佳的传输策略。最后，我们进行了一些实验，结果表明，FSAMPTCP可以自适应地为不同类型的流提供更好的性能。
