介绍了一种基于UDP的高性能数据传输协议UDT,并分析了UDT的拥塞控制机制。UDT是面向连接的流数据传输协议,结合了窗口流量拥塞控制和速率控制两种控制方法,采用了新的DAIMD速率控制算法和带宽估计算法,支持高速广域网上的海量数据快速传输。
This paper introduces a UDP-based high-performance data transmission protocol UDT, and analyzes the congestion control mechanism of UDT. UDT is a connection-oriented streaming data transmission protocol that combines window traffic congestion control and rate control with a new DAIMD rate control algorithm and bandwidth estimation algorithm to support the rapid transfer of massive data over high-speed wide area networks.
