SOA system reliability evaluation method based on complex network theory

Abstract

An SOA system reliability evaluation method based on a complex network theory comprises four steps, belongs to the technical field of complex system reliability and aims at solving the problem that an SOA system is complex in structure and function and a traditional reliability analysis method is difficult to implement and even cannot be implemented and putting forward a methodology for effectively analyzing the reliability of the complex SOA system. The SOA system reliability evaluation method is characterized in that the method is innovatively integrated with the complex network theory, objects in the SOA system and the mutual effect of the objects are abstracted to be nodes and connecting lines in a complex network so as to establish a complex network failure model, a cascading failure model for the SOA system is put forward, and reliability analysis work is completed by utilizing a Monte Carlo simulation experiment on the basis so as to find key software and a weak structure influencing the system reliability. The SOA system reliability evaluation method is not limited by system scale, and increase of the system scale does not enable the calculation complex degree of the method to be remarkably improved. The SOA system reliability evaluation method is clear in physical significance and easily operated and implemented by engineers.

Description

technical field [0001] The invention proposes a SOA system reliability evaluation method based on complex network theory, which belongs to the technical field of software reliability. Background technique [0002] Service-Oriented Architecture (Service-Oriented Architecture--SOA) is a coarse-grained, loosely coupled software architecture, which integrates different functional units of applications, namely services, through well-defined interfaces and contracts between services ( contract) to complete the business requested by the user. This concept was first proposed by Gartner in 1996, and it is believed that SOA will become an absolutely dominant software engineering method in the future. However, only a few companies such as BEA, Microsoft, and IBM have used this architectural approach experimentally. Throughout the development history of the software industry, from the initial process-oriented and object-oriented development to the current popular component-oriented an...

Problems solved by technology

Research has found that the failures of complex systems usually appear suddenly, most of which are caused by seemingly small events, and quickly have a large-scale impact on the entire system like a "butterfly effect"; due to the extensive and close connections between system objects, the system Each object often has a strong fault correlation, causing faults in the system to spread easily; and the fault propagation methods are diverse and there is no deterministic law
