ABSTRACT:
A method and system provide an Internet protocol (IP) session between an originating end-system and a destination end-system through a switched virtual circuit (SVC) short-cut across an asynchronous transfer mode (ATM) network. A first interworking function (IWF) device inserts its ATM address into a transport network hop (THOP) extension object of a resource reservation protocol (RSVP) path message, which may also contain quality of service (QoS) and reverse charging extension objects. IP routers forward the path message through an IP network, without modifying the objects, to a second IWF device, which retrieves the ATM address of the first IWF device. The second IWF device initiates an ATM setup message, including a responsive RSVP reservation request message. The setup message is sent through the ATM network to the first IWF device, which establishes the SVC with the second IWF device, according to the QoS parameter.
