Abstract

In the vast majority of mobile applications, the Transmission Control Protocol (TCP) is still leveraged at the transport layer of the Internet’s protocol stack. But, in many cases, the performance of TCP over mobile networks has been proven sub-optimal in practice, thus causing substantial bottlenecks. Quick UDP Internet Connections (QUIC) is a new protocol, currently being standardized by the Internet Engineering Task Force (IETF), that aims at solving some of the inherent problems of TCP. The purpose of this paper is to provide a comprehensive overview of QUIC and compare the performance of QUIC and TCP in wireless networks. To compare QUIC with TCP under various transmission scenarios over LTE networks, the ns-3 network simulator has been employed. The simulations performed showed that 1) under good or average transmission conditions, QUIC is characterized by a better steady state throughput at the same time achieving quite lower file download times; and 2) under poor transmission conditions, the two protocols exhibit a similar performance.

QUIC与TCP:基于NS-3的LTE性能评估

在绝大多数移动应用程序中，传输控制协议(TCP)仍然被用于互联网协议栈的传输层。但是，在许多情况下，TCP在移动网络上的性能在实践中被证明是次优的，从而造成了严重的瓶颈。快速UDP互联网连接(QUIC)是一种新的协议，目前正在由互联网工程任务组(IETF)进行标准化，旨在解决TCP的一些固有问题。本文的目的是提供QUIC的全面概述，并比较QUIC和TCP在无线网络中的性能。为了比较QUIC和TCP在LTE网络各种传输场景下的性能，我们使用了ns-3网络模拟器。仿真结果表明:1)在良好或平均传输条件下，QUIC具有较好的稳态吞吐量，同时实现较低的文件下载时间;2)在较差的传输条件下，两种协议表现出相似的性能。
