摘要 针对无线互联网中拥塞控制存在的问题,提出了一种支持多径负载均衡技术的TCP拥塞控制策略。该策略主要包括拥塞检测和拥塞控制两个部分。其中基于带宽估计的拥塞检测方法,能有效区分差错丢包和拥塞丢包;在检测到拥塞发生后,采用基于多径负载均衡技术的拥塞控制策略,并使用基于时延估计的多径分组分配策略,在缓解拥塞的同时避免了多路通信的包乱序问题,有效的提高吞吐量,减小端到端时延。 Aiming at the congestion problem in wireless networks, a TCP congestion control strategy based on multi-path load balance is proposed. This strategy includes two parts: the congestion detection and congestion control. The congestion detection, based on band-width estimation, can effectively distinguish from error-based packet loss from congestion-based packet loss. When congestion is detected, the congestion control strategy based on multi-path load balance and the mechanism of multi-path packet distribution are used to solve this problem, thus avoiding the 0-0-0 (Out Of Order) problem. This strategy effectively raises the throughput and reduces the end-to-end delay.
