TCP friendliness has been proposed and used as a fundamental design principle for traffic control in the best-effort Internet in the last few years. The current notion of TCP friendliness is well suitable for applications that can adapt their rates to network congestion. However, a significant fraction of Internet traffic is multimedia streaming traffic, which inherently has limited rate adaptability. As a result, the current notion of TCP friendliness considerably restricts the design space of traffic control protocols for multimedia streaming.The goal of this project is to develop stochastic TCP-friendliness as a new fundamental design principle for traffic control in the best-effort Internet with the following two major research components: 1) developing a stochastic TCP-friendliness framework to qualitatively measure the statistical impact of a traffic control protocol on TCP performance, and to relatively compare the statistical impacts of two different protocols and 2) designing and evaluating a new class of stochastically TCP-friendly traffic control protocols for multimedia streaming, with the aim to considerably improve both TCP and UDP performance when compared with existing TCP-friendly protocols.Broader Impacts: Stochastic TCP-friendliness as a new fundamental design principle will enable other researchers to develop many other new protocols better tailored to their specific needs. It is an important step on the path to move the Internet from a world dominated by TCP users to a world shared among diverse users. This project also includes a strong education component to attract more undergraduate students, and to engage both undergraduate and graduate students into research.

在过去几年中，TCP 友好性已被提出并用作尽力而为互联网中流量控制的基本设计原则。当前 TCP 友好性的概念非常适合能够根据网络拥塞调整速率的应用程序。然而，互联网流量的很大一部分是多媒体流流量，其固有的速率适应性有限。因此，当前 TCP 友好性的概念在很大程度上限制了多媒体流的流量控制协议的设计空间。该项目的目标是开发随机 TCP 友好性作为尽力而为互联网中流量控制的新基本设计原则具有以下两个主要研究组成部分：1）开发随机 TCP 友好性框架，以定性测量流量控制协议对 TCP 性能的统计影响，并相对比较两种不同协议的统计影响；2）设计和评估新一类的用于多媒体流的随机 TCP 友好流量控制协议，与现有的 TCP 友好协议相比，旨在显着提高 TCP 和 UDP 性能。 更广泛的影响：随机 TCP 友好作为一种新的基本设计原则将使其他研究人员能够开发许多其他新协议更好地适合其特定需求。这是将互联网从 TCP 用户主导的世界转向多元化用户共享世界的重要一步。该项目还包括强大的教育成分，以吸引更多本科生，并让本科生和研究生参与研究。
