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.
Claims23
A telecommunications network for establishing communication between at least one originating station and at least one destination station, comprising:
- a plurality of IP switches for addressing and routing data in accordance with an Internet protocol and an ATM protocol;
- a server, coupled to at least one of the IP switches, for receiving at least one service attribute requested by an originating station in communication with the IP switch;
- a network control point (NCP) for providing data in response to a request from the server for providing said at least one service attribute;
- at least one address database associated with each of the IP switches, said at least one address database including a subset of the data available in the NCP.
A method for establishing communication between at least one originating station and at least one destination station over a network including a plurality of IP switches for addressing and routing data in accordance with an Internet protocol and an ATM protocol, said method comprising the steps of:
- receiving an IP packet from the originating station addressed to the destination station;
- identifying an entry in an address database, that includes a subset of data available in a Network Control Point (NCP), for providing data in response to a request for information, the database containing address correspondence data for routing the IP packet to the destination station;
- identifying, by launching an inquiry to the NCP, at least one service attribute associated with transmission of the IP packet to the destination station;
- routing the IP packet to the destination station in accordance with the service attribute.
