STMB:a New Multi-layer Structure Service Composition Model
Anfeng Liu · Journal of Chinese Computer Systems · 2010
Since there are considerable network communication cost in the service composition model presently. A new multi-layer structure model called STBM(Spanning Tree Based Model) has been proposed in this paper. STBM includes three abstract layers,the service registration layer,the virtual service layer and the service supply layer. The service composition platform can be constructed for the clients with the orthogonal function supplied collectively by each layer. Firstly,the service registration layer is to register the distributed service and index; Secondly,the SVCN(Services Virtue Composition Networks) can be constructed by the service composition relationships of different spanning trees ,which is structured with the functional relationships of the virtual service layer. STBM,with the same service composition effect,has the lower average network communication stream than Spidernet dramatically by the theoretical analysis.
