Huangfu Da-e · Jisuanji fangzhen · 2013
The delay tolerance of the network congestion avoidance optimization algorithm. In the network delay tolerance in the custody transfer mechanism,lead to network resources limited sexual depletion and form a network congestion. The traditional TCP congestion control algorithm in the control end there quick feedback under the premise of node,the slow start,fast retransmission congestion control strategy,but tolerance network does not exist fixed control end,up and down link bandwidth asymmetry,it is difficult to establish accurate congestion acknowledgement of receipt,thereby control the effect not beautiful. In order to avoid the defect,the article puts forward a method based on network congestion state parameter optimization of the network delay tolerance of congestion avoidance optimization algorithm. According to TCP protocol data feedback mechanism,can estimate delay tolerance of network bandwidth. According to the data transmission waiting time difference value,can calculate the length for data transmission. Using network congestion state parameter optimization method,which can achieve the delay tolerance of the network congestion avoidance optimization. The experimental results show that this algorithm using delay tolerance network congestion avoidance optimization,can improve the efficiency of data transmission.
