Embodiment Construction

[0093] The technical solution for realizing the present invention is as follows: firstly assign transactionality to Web services, then analyze the composition problem of transactional required services, and then analyze the performance problems of compositional services with transactional attributes, and finally, according to the performance comparison of transactional compositional services, propose A service selection method based on a combination of transactions and QoS. Specifically include the following steps:

[0094] Step 1. When selecting the current component service, obtain the candidate component service that meets the transactional requirements according to the transaction characteristics of the suitable component service that has been selected above, and in accordance with the rules of the transaction composition service.

[0095] The second step is to evaluate the performance of each candidate component service, considering the QoS and transactional requirements ...

Abstract

The invention relates to the technical field of computer networks and especially relates to a transactional and QoS (Quality of Service) combination based service quality performance predication method and device. The method includes enabling Web service to be transactional and analyzing a combination problem of the service with transactional demands; analyzing a performance problem of service with transactional attribute combination; and according to performance comparison of the transactional combination service, proposing a transactional and QoS combination based service selection method. The invention also includes a service quality performance predication device employing the above method. The device also includes an extraction module, a processing module, an extraction module and a determining module.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a service quality performance prediction method and device based on a transaction and QoS combination. Background technique [0002] Web service is a technology for automatic interaction between businesses. Enterprises can publish their internal business processes as a service, and then provide their services on the Web. With the deepening of the application, the business process may contain one or more business functions. Since these businesses may call Web services from different organizations, they need to be combined in a certain way to work together, and to ensure the reliability of their operation and the consistency of results. sex. In a complex network environment, service composition may become very complex due to the following problems: component services may run for a long time, service environments are loosely matched and self-asynchronous, the composition ...
