Towards the Service Composition Through Buses

Bus model is a kind of service integration model that is responsible for integrating heterogeneous services. Buses not only store the messages exchanged between services, but also coordinate the service executions. Recently, the bus model has been widely used in engineering field to manage interactions between services and support a given choreography. In this paper, we propose the formal design of services compatible with the bus infrastructure, and make some analyses of bus composition patterns. The service model is formalized on three levels and a composition approach is proposed to describe the composition patterns with the bus infrastructure.
