Study of coordinative service bus based service execution platform

Enterprise Service Bus (ESB) is a promising tool to solve the problem of service composition at the background of service integration. Traditional ESB is not efficient enough for dynamical composition; and do not have the coordinative distributed execution feature, which can provide both effective and rapid service composition. This paper proposes a Coordinative Service Bus based Execution Platform at the basis of service coordination and service bus. Through creating Execution Binding Map (EBM), the platform uses a method of pre-binding optimal services to improve efficiency of service selecting and invoking. In addition, it uses a method of Multi-level Request Scheduling with Feedback to ensure the overall efficiency of the platform and to reduce the possibility of failure of partial services.
