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 existing problems of congestion control in wireless Internet, a TCP congestion control strategy supporting multipath load balancing is proposed. The strategy mainly includes two parts: congestion detection and congestion control. The congestion detection method based on bandwidth estimation can effectively distinguish between error packet loss and congestion packet loss. After detecting the congestion, congestion control strategy based on multi-path load balancing technology is adopted and multi-path packet allocation based on delay estimation Strategy to alleviate the congestion at the same time avoid the multi-channel communication packet disorder, effectively improve the throughput and reduce end-to-end delay.
