This paper presents the novel integrated LOBS/GMPLS network testbed. Dynamic interworking technologies between GMPLS network and LOBS network and potential survivability schemes in this multilayer network are investigated by experimentally evaluating the TCP and popular streaming media service performance over an integrated LOBS/ GMPLS testbed.展开更多

As a workflow is the composition of a series of interrelated web services which realize its activities, the interoperability of workflows can be treated as the composition of web services. To address it, a framework for interoperability of business process execution language （BPEL）-based workflows is presented, which can perform three phases, that is, transformation, eonformance test and execution. The core components of the framework are proposed, especially how these components promote interoperability. In particular, dynamic binding and re-composition of work-flows in terms of web service testing are presented. Besides, an example of business-to-business （B2B） collaboration is provided to illustrate how to perform composition and conformance test.展开更多
