Miao Zhao, Hui Wang · Jisuanji gongcheng · 2012
In view of the traditional Transmission Control Protocol(TCP) control protocol efficiency in heterogeneous network,this paper gives the definition of the cognition of the network status,proposes and constructs a network cognitive model which makes the length of bottleneck link queue as the target parameter.This model uses TCP-L transmission control protocol to finish simulation experiments.Experimental result shows that this model can more accurately estimate the dynamic change trend of bottleneck link queue's length,and its estimate can be more accurately located in the gathering area of true values.Under different background flow conditions,the TCP-L protocol can stabilize sending window,round trip transmission delay and queue length,reduce congestion and improve throughput and transmission efficiency.
