Problems solved by technology

The problems of this method are as follows: first, it only considers the situation that the QoS attribute of the service is an exact real number; second, the analysis of user preference is limited to the setting of subjective weight; third, it does not filter candidate services, but Sorting all candidate services, the decision-making efficiency is relatively low
However, this method is relatively rough in the research on service ranking after service set reduction.

Embodiment Construction

[0070] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0071] A dynamic QoS service selection method oriented to user requirements, comprising the following steps:

[0072] Step 1: From the perspective of user needs, the evaluation indicators are divided into hard demand indicators and non-hard demand indicators, and services are initially screened by setting tolerance thresholds for hard indicators;

[0073] For different users, due to their different personal needs, the importance of different indicators is also different. In general, user preferences are based on the user's understanding of the decision-making problem,...

Abstract

The present invention proposes a user-oriented dynamic QoS service selection method and its system. The method divides the evaluation index into rigid demand index and non-hard demand index, initially screens services according to the rigid demand index, and determines the candidate service set; The QoS attribute of the service and the QoS requirement of the user are converted into the QoS attribute interval of the candidate service and the QoS requirement interval of the user, and the relative advantage degree is calculated; the candidate service is reduced based on the Skyline method, and the Skyline service set is determined; the Skyline service set is determined based on the TOPSIS method. The service set sorts the services to determine the optimal service. The invention improves the reliability and efficiency of service selection.

Description

technical field [0001] The invention relates to network data communication technology, in particular to a dynamic QoS service selection method and system oriented to user requirements. Background technique [0002] In recent years, with the rapid development and wide application of Internet and cloud computing technologies, more and more software services with similar functions and different performances are deployed in the cloud platform, which makes the number of services increase exponentially and makes it difficult for users to choose services steep rise. Since different users have different service requirements, how to efficiently and accurately select a service that meets user needs from numerous services has become a crucial step in the service selection process. [0003] Quality of Services (QoS) has nothing to do with the functions implemented by services, and is a comprehensive indicator to measure service performance. The service selection method based on QoS at...
