International ClassesH04L 012/28H04L 012/56 AbstractA mechanism for providing point-to-point and point-to-multipoint connections in an ATM network converts VPI/VCI information at an ingress ATM device on incoming cells from a source endpoint to internal VP/VCI information that is used to switch the cells through an ATM network to an egress ATM device. At the egress ATM device, the internal VPI/VCI information is converted back to the source VPI/VCI information for transmission of cells to the destination endpoint. In such a manner, an ATM switch network is able to provide point-to-point connections without requiring individual configuration of VPI/VCI information at the ingress and egress ATM devices.Other References
