摘要
TCP是因特网上最通用的传输层协议之一，其核心是拥塞控制机制。文中在介绍TCP基本机制的基础上。对TCP拥塞控制的改进机制进行了讨论，这些改进包括：避免不必要的重传超时、撤销不必要的拥塞控制、显式拥塞通知和数据损伤通知等。
TCP is one of the most widely used transmission layer protocols, and congestion control is the core of TCP. This paper first introduces the basic congestion control mechanism of TCP, and then discusses several changes of TCP congestion control. The changes in TCP include avoiding unnecessary retransmit timeouts, undoing unnecessary congestion control, explicit congestion notification, and data corruption notification.
