基于自拥塞理论的传输控制算法设计与实现

Design and Implementation of Data Transmission Algorithm Based on Self-congestion Theory

对可用带宽测量算法SLOPS进行分析,针对其探测流量过大,测量结果易受背景流量影响等缺陷,设计实现了一种基于自拥塞理论的数据传输控制算法DTCA(Data Transmission Control Algorithm)。该算法通过发送轻量级的探测报文来探知当前网络状态,进而调整数据发送速率,以达到充分利用带宽资源的目的。测试结果表明,该算法能够自适应的调整数据发送速率,提高带宽利用率。

The available bandwidth t SLOPS is analyzed. Aiming at its requirement for too much detect-traffic and the shortcoming that the final result is easily to be affected by the cross traffic, a new Data Transmission Algorithm DTCA is presented. DTCA dynamically sends light-weight packets to detect the state of the network, and adjusts the sending rate to approach the available bandwidth. The experiment later shows its efficiency.
