Abstract
Abstract A telecommunications network is provided for establishing communication between at least one originating station and at least one destination station. The network includes a plurality of IP switches for addressing and routing data in accordance with an Internet protocol and an ATM protocol. A server, which is coupled to at least one of the IP switches, receives at least one service attribute requested by the originating station in communication with the IP switch. A network control point (NCP) is employed to provide data, in response to a request from the server, pertaining to the service attribute. At least one address database is associated with each of the IP switches. The address database includes a subset of the data available in the NCP.
