Abstract:
A method of establishing an S-PVC (soft private virtual connection) connection in a PNNI (private network-network interface) network of a plurality of peer groups, each of which includes at least an ATM (asynchronous transfer mode) switching apparatus as an ATM node, comprising the steps of:(a) setting a first identifier and first designated route data associated with said S-PVC channel in each of said plurality of peer groups; (b) in said ATM node in each of said plurality of peer groups, receiving a call originating request including second designated route data and a second identifier; (c) comparing said first identifier and said second identifier; (d) generating a next call originating request containing third designated route data as said second designated route data and said second identifier for a next node based on said first and second designated route data and said second identifier when said first identifier and said second identifier are coincident with each other; (e) transmitting said next call originating request to said next node; and (f) repeating said steps (b) to (e) over each of said plurality of peer groups.
