【摘要】 网络拥塞是由于网络业务流不可预测的流量突发现象造成的.文章从考虑网络业务流突发现象产生的特点出发,采用可用带宽测量技术和流量整形技术,提出了一种针对传统网络拥塞控制算法的改进算法(TCP-Shape).改进后的拥塞控制算法能够快速地探测到网络链路中可用剩余带宽并能够有效地消除网络业务流中的突发现象.使得在网络业务流的吞吐量和数据报文段的丢失率等性能上,更加优越于传统拥塞控制算法所获得的性能.更多还原

【Abstract】 Network congestion is caused by the unexpected burst.According to characteristic analysis of network traffic burst,the paper proposes a renovation method of congestion control algorithm(TCP-Shape) against the traditional congestion control algorithms,which uses dummy data segment probe to probe the available bandwidth in a TCP path and use flow shape techniques to make the flow look like more smoother.The experiments also show that the new congestion control algorithms can do better on data segment drop and throughout performance against the traditional congestion control algorithms.更多还原
