US Patent:
6385193, May 7, 2002
Filed:
Apr 4, 2001
Appl. No.:
09/825651
Inventors:
Seyhan Civanlar - Middletown Township Monmouth County NJ
Don Richard Coffield - Locust NJ
James J. Mansell - Fair Haven NJ
Vikram R. Saksena - Freehold NJ
Assignee:
ATT - Basking Ridge NJ
International Classification:
H04L 1266
US Classification:
370352, 370466, 379 8817
Abstract:
In one embodiment of the invention, an apparatus is provided for establishing a communication session between first and second terminals in communication over a plurality of networks that employ differing transmission standards. The plurality of networks are selected from among a circuit switched network (e. g. , a telephony network), a connectionless packet switched network (e. g. , the Internet) and a connection-oriented packet switched network (e. g. , an ATM or frame relay network). The apparatus includes a call set-up translator for translating among call set-up protocols associated with the circuit switched network, the connectionless packet switched network and the connection-oriented packet switched network. An encoding format translator is provided for translating among encoding protocols associated with the circuit switched network, the connectionless packet switched network and the connection-oriented packet switched network. Also provided is an address database for storing a plurality of addresses in different formats for each registered terminal, which includes the first and second terminals.

US Patent:
6483832, Nov 19, 2002
Filed:
Apr 14, 1998
Appl. No.:
09/060292
Inventors:
Seyhan Civanlar - Middletown Township, Monmouth County NJ
Don Richard Coffield - Locust NJ
Rustom K. Masalawala - New York NY
Vikram R. Saksena - Freehold NJ
Assignee:
ATT Corp. - New York NY
International Classification:
H04L 1228
US Classification:
370390, 370432
Abstract:
A method and a system for forwarding multicast data packets across a plurality of telecommunications subnets interconnected by routers in which a data packet is received within a subnet of the plurality of telecommunications subnets. When the data packet is a multicast data packet, a multicast IP address for the multicast data packet is determined. A multicast forwarding database is accessed for determining a LAN Emulation Client associated with the multicast IP address, and a Broadcast Unknown Server associated with the multicast IP address for the multicast data packet is determined. The multicast data packet is sent to the Broadcast Unknown Server associated with the multicast IP address for the multicast data packet through the LAN Emulation Client using a point-to-point connection. The Broadcast Unknown Server sends the multicast data packet inter-subnet to each router associated with the multicast IP address for the multicast data packet using a point-to-multipoint connection, with at least one multicast host being connected to a subnet that is different from the subnet in which the multicast data packet was received.
