提出了一种基于方程的单播拥塞控制机制。当前Internet中的大多数尽力而为流量都由占主导地位的传输协议TCP提供良好的服务。然而，诸如尽力而为单播流媒体的流量可以用于TCP友好的拥塞控制机制，该机制避免响应于单个分组丢弃而将发送速率降低一半。使用我们的机制，发送方显式地调整其发送速率作为丢失事件的测量速率的函数，其中丢失事件由在单个往返时间内丢弃的一个或多个数据包组成。我们使用模拟和实验在互联网上探索performance.We认为基于方程的拥塞控制的组播流量的拥塞控制的一个有前途的发展途径，所以这项工作的另一个动机是奠定了良好的基础，组播拥塞控制的进一步发展。
This paper proposes a mechanism for equation-based congestion control for unicast traffic. Most best-effort traffic in the current Internet is well-served by the dominant transport protocol, TCP. However, traffic such as best-effort unicast streaming multimedia could find use for a TCP-friendly congestion control mechanism that refrains from reducing the sending rate in half in response to a single packet drop. With our mechanism, the sender explicitly adjusts its sending rate as a function of the measured rate of loss events, where a loss event consists of one or more packets dropped within a single round-trip time. We use both simulations and experiments over the Internet to explore performance.We consider equation-based congestion control a promising avenue of development for congestion control of multicast traffic, and so an additional motivation for this work is to lay a sound basis for the further development of multicast congestion control.
