Abstract :
In this paper, we introduce WNET/WSIP, a web service enabled converged communication infrastructure that is integrated with VoIP SIP (Session Initiation Protocol). WNET/WSIP consists of a network of WSIP node and it is based on two-way, full duplex web service interaction. WSIP is a new class of IP communication endpoints. Each WSIP node is both a SIP endpoint that communicates in the SIP world through SIP signaling, and a web service SOAP node that provides an application protocol layer alternative to SIP and a generic service integration environment for binding SIP based communication in web services. From service perspective, WNET/WSIP is an application layer protocol overlay for resilient and versatile communication services over IP. It allows dynamic service discovery and binding that integrate SIP services as a SOA component in business transactions. It separates service integration/extension environment from SIP signaling. The ubiquitous service integration nature of web service provides a disciplined solution to monitor the WNET/WSIP network. It supports dynamic service monitoring, provisioning, endpoint discovery and update, etc. In particular, we introduce the approach of using WSSecurity [12] to provide end-to-end message level security over IP in WNET/WSIP. These new capabilities are essential to the success of reliable communication services. The proposed approach was implemented in a prototype research system. Advantages of WNET/WSIP were realized and observed.
