Mechanism of dependable adaptive dynamic service based on Enterprise Service Bus

The idea of service-oriented architecture is always used for modern software system designing. SOA offers methods for system development and system integration. In order to meet the demand of dynamic business, improve the quality of service and quality of experience, this article increases the dynamic service execution engine on the integration layer based on industry standard architecture model of S3. We propose a Dependable Adaptation Dynamic Enterprise Service Bus(DAD-ESB) and design Dependable Service Select Algorithm(DSSA). At last, a performance evaluation experiment between static and dynamic dependable service composing is tested. The experimental results show that the dynamic dependable service composition has the high advantages, and with the dependability increasing, the success rate of calling is much higher.
