The invention provides a method for discriminating packet loss in heterogeneous network based on fuzzy comprehensive evaluation. In this method, the first packet one-way delay factors on the detection of the frame and the average packet loss rate as fuzzy comprehensive evaluation parameter set; in the packet, using one-way delay and average packet loss rate respectively to make independent judgment, two factors were set parameters on the current network status evaluation value; the dynamic weight distribution function with the one-way delay and average packet loss rate were calculated and normalized to two dynamic weight distribution function, to determine the relative weight of one-way delay and average packet loss rate of the value of the relative weight value; fuzzy transformation, obtain comprehensive evaluation, so as to distinguish the cause of packet loss. Experiments show that this method is better than the current TCP version and the existing methods.

一种基于模糊综合评判的异构网络丢包区分方法，其特征在于： （１）将包对探测帧的单向传输时延和平均丢包率作为模糊综合评判的因素集参数； （２）在发生丢包时，利用所述平均丢包率和所述单向传输时延分别进行评判，得到两个所述因素集参数对 当前网络状况的评判值； （３）分别计算与所述平均丢包率和所述单向传输时延相关的动态权重分布函数，并对两个动态权重分布函数做归一化处理，确定所述平均丢包率和所述单向传输时延的相对权重值； （４）对所述相对权重值进行模糊变换，获得综 合评判，从而对丢包原因进行区分。
