ESB Infrastructure's Autonomous Mechanism of SOA

Service-oriented architecture (SOA) is the architecture of software or information system, as well as a concept of coarse-grained components and loosely coupled framework. But SOA is generally believed as a simple Web service integration. This paper deeply discusses some concepts on SOA, insists that SOA is a developing methodology rather than a specific technology. Moreover, the paper expatiates on the topology of enterprise service bus (ESB) model. In this model, ubiquitous-autonomous mechanism to union ESB infrastructures is introduced. Mechanism is designed from the inspiration of routing protocols and grid resources finding calculation. By designing, many functions are supported, including service dynamics, the load-aware self-adaptation and fault tolerance. In the end, the performance of mechanism was evaluated through simulations and applications. Experimental results show that this pervasive mechanism has low bandwidth, fast convergence and the ability to recover from emergencies quickly.
