Abstract

Provided are a Web service Quality of Service (QoS) distributed measurement system and method. The Web service quality distributed measurement system is provided with a center node and a plurality of measurement nodes. The Web service QoS distributed measurement method is characterized in that network coordinates of user hosts, the plurality of measurement nodes and Web service deployment hosts, namely service deployment nodes, in an abstract network coordinate system are respectively calculated by aid of the network positioning technology according to a Web service QoS estimation model, and similarity of the user hosts and the measurement nodes is calculated so as to estimate QoS attribute values capable of being obtained by users. The Web service QoS distributed measurement method and system can fast and accurately estimate Web service QoS capable of being obtained by the user sides in different regions and / or different network environments, and the Web service QoS includes response time and reliability. The Web service QoS distributed measurement method has strong instantaneity and does not depend on historical QoS data of the users, dost not add additional load to the users, and is transparent in the estimation process. The Web service QoS distributed measurement method and system are characterized in that the network system is mapped into the multi-dimensional coordinate system, response time and reliability of Web service and capable of being obtained by the user sides can be estimated by combining similarity of the user hosts and the measurement nodes, and true and credible data can be obtained.

Description

technical field

[0001] The invention relates to a distributed QoS measurement system and method for Web service quality, in particular to a method and system for Web service quality measurement based on a distributed architecture, and belongs to the technical field of computers and network communications. Background technique

[0002] Web service is a service-oriented architecture (Service-Oriented Architecture) technology. It provides services through standard Web protocols to ensure that application services on different platforms can interoperate. Its communication protocol is mainly based on SOAP, and UDDI is used to discover and obtain services. metadata. Due to the dynamics and unpredictability of the Internet, the rendering results of the same service on different clients are quite different. At the same time, there are many Web services with the same or similar functions in the network. How to choose the appropriate service for users in different regions and differen...
