System and method for monitoring quality of Web services (QoWS) in end-to-end manner

Abstract

The invention discloses a system and method for monitoring quality of Web services (QoWS) in an end-to-end manner. The monitoring system comprises a registration module, an SNMP (simple network management protocol) proxy module, a monitoring module and an evaluation module. The monitoring method comprises the following steps of: A, registering; B, generating parameters and parameter values of theagreed quality; C, sending the agreed quality parameters; D, obtaining the service session information; E, obtaining the management information of the service session; F, obtaining the delivered quality parameter values and perceived quality parameter values corresponding to the agreed quality parameters; G, sending the delivered quality parameter values, the perceived quality parameter values and the transmitted quality parameter values to the evaluation module by the monitoring module; and H, evaluating and counting the quality information of the service by the evaluation module. The systemand method disclosed by the invention are simple and effective, have relatively low overhead, and can objectively and comprehensively reflect the quality information of the service session so as to provide an objective basis for the service selection.

Description

technical field [0001] The invention belongs to the field of Web service combination, and in particular relates to an end-to-end Web service quality monitoring system and method. Background technique [0002] The software service technology represented by Web service is developing rapidly, and its excellent characteristics of loose coupling and platform independence are very suitable for the interoperability and integration of heterogeneous applications in the Internet environment. With the increasing number of Web services (hereinafter referred to as services) with the same or similar functions, users usually have multiple candidate Web services to choose from when using Web services or creating composite services. On the basis of satisfying user functional requirements, Quality of Web Services (QoWS) has become a criterion for evaluating candidate Web services, and has also become an important factor affecting the development of Web services. What the service provider pro...

AI Technical Summary

Problems solved by technology

Monitoring the quality of Web services at the service provider can reflect the actual delivery quality of the service, but cannot reflect the actual perceived quality of the user; similarly, monitoring the quality of the service at the user can reflect the actual perceived quality of the customer. quality, but cannot objectively reflect the quality delivered by the service provider

However, the existing web service quality monitoring system either takes the service provider's delivery quality as the monitoring standard, or the service user's perceived quality as the monitoring standard, and lacks a real, objective and comprehensive monitoring mechanism
