  • Patent number: 9276849
    Abstract: A new type of data transport service which uses a frame relay layer 2 data link connection identifier (DLCI) to select among various service types, feature sets, and/or closed user groups (CUGs). A layer 3 address may be extracted from a layer 2 frame, and the layer 3 address information may be used to route a data packet over a packet-switched network according to the service classes, feature sets, and/or CUGs selected. At the destination, the layer 3 data packet may again be enclosed in a layer 2 frame with a DLCI indicating the service classes, features sets, and/or CUGs. Because the use of conventional permanent virtual circuits (PVCs) is not required in aspects of the invention, new methods of measuring and managing network traffic are presented.

  • Patent number: 6483832
    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.

  • Patent number: 6385193
    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.

  • Patent number: 6298120
    Abstract: A method is disclosed for establishing communication between an originating station and a destination station over a computer network such as the Internet, for example. In accordance with the invention, at least one service attribute requested by the originating station is received over a signaling path. A communication path is then established between the originating and destination stations in conformance with the requested service attribute. The signaling path is an out-of-band signaling path with respect to the communication path.

  • Patent number: 6252857
    Abstract: A method and apparatus for providing provisioned and dynamic QoS in a communications network. In one embodiment, provisioned QoS is provided in a network using RP by deciding to establish an SVC for a sender and receiver. An NHRP resolution reply containing QoS information is received in response to an NHRP resolution request. An appropriate SVC is then established using the QoS information. In another embodiment, dynamic QoS is provided in a network using RSVP. A first RSVP multicast connection tree a first QoS is established in response to an RSVP request. When a second RSVP request is ived, a new tree is created if the QoS in the second RSVP request is not within a threshold e from the QoS of the first tree. If the QoS in the second RSVP request is within the threshold range, a new branch is added to the first tree and no new RSVP connection tree is required.
