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.
【技術實現步驟摘要】
【技術保護點】
一種基于模糊綜合評判的異構網絡丟包區分方法，其特征在于： （１）將包對探測幀的單向傳輸時延和平均丟包率作為模糊綜合評判的因素集參數； （２）在發生丟包時，利用所述平均丟包率和所述單向傳輸時延分別進行評判，得到兩個所述因素集參數對 當前網絡狀況的評判值； （３）分別計算與所述平均丟包率和所述單向傳輸時延相關的動態權重分布函數，并對兩個動態權重分布函數做歸一化處理，確定所述平均丟包率和所述單向傳輸時延的相對權重值； （４）對所述相對權重值進行模糊變換，獲得綜 合評判，從而對丟包原因進行區分。
