通信的新趋势，特别是多播和实时音频/视频流应用的部署，可能会增加互联网中非tcp流量的百分比。这些应用程序很少以tcp友好的方式执行拥塞控制；它们不能与构建在TCP上的应用程序（如Web浏览器、FTP或电子邮件客户端）公平地共享可用带宽。Internet社区非常担心当前的发展可能导致拥塞崩溃和TCP通信的匮乏。由于这个原因，正在开发对TCP友好的协议，这些协议对共存的TCP流的行为是公平的。我们介绍了目前TCP友好性的研究方法，并讨论了它们的特点。研究了单播和组播拥塞控制协议，并对不同的方法进行了评估。
New trends in communication, in particular the deployment of multicast and real-time audio/video streaming applications, are likely to increase the percentage of non-TCP traffic in the Internet. These applications rarely perform congestion control in a TCP-friendly manner; they do not share the available bandwidth fairly with applications built on TCP, such as Web browsers, FTP, or e-mail clients. The Internet community strongly fears that the current evolution could lead to congestion collapse and starvation of TCP traffic. For this reason, TCP-friendly protocols are being developed that behave fairly with respect to coexistent TCP flows. We present a survey of current approaches to TCP friendliness and discuss their characteristics. Both unicast and multicast congestion control protocols are examined, and an evaluation of the different approaches is presented.
