Problems solved by technology

The advantage of this method is that it has less impact on the composite service itself. The disadvantage is that when restarting the composite Web service, some atomic services that are unnecessary to restart will be restarted, the system has a large additional overhead, and the efficiency of fault recovery is low.

Abstract

The invention discloses a fast recovery method for composite Web service failure. Including the following steps: 1) setting a fault checkpoint in each atomic service of the composite Web service, the fault checkpoint monitors the atomic service where it is located, and sends monitoring information to the outside; 2) Sets a detection agent M-Agent at the server end of the composite Web The agent M-Agent receives the monitoring information sent by the failure checkpoint, and obtains the actual execution topology of the composite Web service; 3) The detection agent M-Agent locates the failed atomic service of the composite Web service; 4) Sets multiple R‑Agent, a level recovery agent, restarts failed composite Web services using a micro-restart-based recursive recovery method. By adopting the failure fast recovery method of the combined Web service of the present invention, the failure recovery of the combined Web service can be quickly and efficiently completed, and the reliability of the combined Web service can be improved.

Description

technical field [0001] The invention relates to the field of computer networks and applications, in particular to a fast recovery method based on Web service failure. Background technique [0002] Distributed computing based on Web services is the main trend in the development of the Internet. The rapid development and wide application of Web services have promoted the prosperity of Web service composition technology. Web technology is characterized by high interoperability, cross-platform, and loose coupling. Collaboration between services enables large composite services. However, the network environment where Web services are located is an unreliable and heterogeneous dynamic environment. Network failures, service denial attacks, infrastructure failures, atomic service updates and upgrades may cause service operation failures, or even unavailability and loss of response. , hindering the application and promotion of Web service composition technology. Therefore, how to q...
