Virtual Network for Development and Execution of Service-Oriented Applications

Service-oriented computing represents an emerging paradigm where software functionalities are delivered to consumers as services rather than products. Service-oriented applications consist of services available on the Internet and the coordination logic that binds independent services into the application-specific workflow. Execution of distributed applications in shared and dynamic Internet environments faces two open issues: security of service invocation and dependence of coordination logic on physical distribution of services. In this paper, we propose a model for development and execution of service-oriented applications based on a virtual network. Virtual network provides the environment for secure execution of service-oriented applications independent of the physical network configuration. Virtual network is based on service-oriented architecture, which enables run-time management of virtual network by users and distributed applications
