显式拥塞控制研究

The Summary of Explicit Congestion Control

随着互联网络技术的发展,高带宽延迟积的高速网络成为主流网络,TCP拥塞控制算法因为协议固有的设计缺陷,无法理想地处理高速网络中的拥塞问题,显式拥塞控制协议有效地克服TCP的设计缺陷,较为理想地解决这些问题。论述显式拥塞控制的工作流程以及三种显式拥塞控制协议XCP、EMKC和JetMax。

With the rapid development of Internet, high speed network with large bandwidth- delay product becomes common. Because of the intrinsic limitation in the protocol design, TCP congestion control is unable to deal with the congestion problems in the high speed network ideally. Free from the constraint of the TCP, explicit congestion control protocol resolves the congestion problems efficiently. This paper presents the principles of the explicit congestion control, and describes three explicit congestion control protocols named XCP, EMKC and JetMax.
