Grey correlation and fuzzy evaluation method and system for multipath transmission network performance

Abstract

The invention relates to a grey correlation and fuzzy evaluation method and system for multipath transmission network performance. The method comprises the following steps: acquiring multi-path transmission network information to be evaluated; wherein the multi-path transmission network information comprises network quantity information and network evaluation index information; calculating a membership vector value of each evaluation comment corresponding to each network in the multipath network according to the network quantity information, the network evaluation index information and a pre-established network performance evaluation model; wherein the pre-established network performance model is established by analyzing the established multi-path transmission network by adopting a grey correlation analysis method and a fuzzy comprehensive analysis method, and is used for recording a relationship between network evaluation indexes and membership vectors of evaluation comments; selecting an evaluation comment corresponding to the maximum membership vector value as a final evaluation result of each network; and determining the performance of each network in the multipath network according to the final evaluation result. According to the network performance analysis method, the evaluation accuracy can be greatly improved.

Description

technical field [0001] The present application relates to the field of network transmission technology, in particular to a gray correlation and fuzzy evaluation method and system for multi-path transmission network performance. Background technique [0002] In recent years, with the continuous development of network technology, video services have developed rapidly, and various types of videos have emerged, such as OTT (Over The Top) videos, live broadcasts and other videos. In the video service, video transmission is a key link, which directly affects the effect of video playback. MPTCP multi-path parallel transmission technology means that in the process of video transmission, video data can be transmitted simultaneously through multiple paths, aggregated bandwidth, and improve network transmission rate. Although the multipath transmission technology has many transmission advantages, it is necessary to evaluate the transmission performance (such as efficiency, etc.) of th...

Problems solved by technology

Among them, the fuzzy analytic hierarchy process and the linear weighting method both use subjective methods to determine the weight, which will cause subjective bias; while the principal component analysis method solves the problem of determining the evaluation weight, but it will cause information loss; the fuzzy comprehensive evaluation method cannot solve the evaluation problem. The evaluation problem of fuzzy and random correlation in the process; the BP neural network method and the improved support vector machine method both use the fuzzy comprehensive evaluation method to obtain the evaluation value and then train and build the model, and the quality of the model is limited by the fuzzy comprehensive evaluation method

But these models cannot be used for multipath networks

Therefore, there is currently no established method to measure or evaluate the network quality under the multi-path transmission network and verify it through the actual network environment, so as to evaluate the user experience of watching videos to a certain extent
