Patent number: 8737416Abstract: One or more virtual access nodes manage multiple physical links connecting a digital subscriber line access multiplexer and an intelligent network interface device by logically bonding physical ports together into a group. Physical ports bonded in a logical group have equal priority with respect to one another. Thus, no master-slave relationship exists between the physical ports in the logical group. Traffic associated with a site is transmitted over physical links associated with the logical group of physical ports to a customer premises network interface device. The customer premises network interface device subsequently aggregates the received traffic and provides an increased bandwidth to the site over the physical links. The quality of communication is based on the number of operational physical links associated with the logical group. As long as at least one physical link associated with the logical group remains operational, communication will be enabled.Type: GrantFiled: December 4, 2007Date of Patent: May 27, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: Richard T.

Patent number: 8654776Abstract: A system and method is provided for scheduling transmissions from a plurality of services operating over a widely distributed communications network. A headend communications device (such as a cable modem termination system) arbitrates bandwidth among a plurality of cable modems configurable for bi-directional communications. The headend grants a bandwidth region to a specified cable modem or assigns contention regions for a group of cable modems. Each cable modem contains a local scheduler that sends requests for bandwidth according to local policies or rules. Upon receipt of a grant from the headend, the local scheduler selects packets to be transmitted to best serve the needs of the services associated with the cable modem. Accordingly, a service requesting bandwidth may not be the service utilizing the grant corresponding to bandwidth request. Nonetheless, the local scheduler manages bandwidth allocation among its local services such that all requesting services eventually receive bandwidth.Type: GrantFiled: May 5, 2011Date of Patent: February 18, 2014Assignee: Broadcom CorporationInventors: Dolors Sala, Ajay Chandra V.

Patent number: 8553707Abstract: The present disclosure provides systems and methods for administrative boundaries in a single domain optical network such as emulation of an External network-network interface (ENNI) using an Internal-Network to Network Interface (INNI). For example, in a single monolithic domain, a network and associated network elements may discover network elements, build topology, compute paths, establish new calls, etc. A user may identify/mark specific links as emulated “ENNI” links with the specific links actually being INNI links. As a call traverses this emulated link, a new call is initiated (much in the same way a new call segment would be created for a call). Signaling proceeds as normal. When the call set-up is fully complete, instead of a single call segment, many call segments exists. Advantageously, this allows use of INNI control plane features while allowing a network operator to future-proof their network by installing call segments at future boundary points.Type: GrantFiled: March 1, 2011Date of Patent: October 8, 2013Assignee: Ciena CorporationInventors: Gerard L Swinkels, Darek Skalecki, Manuel Damas

The first network switch may be rated to handle, for example, a greater data rate than the second network switch. The first cable may not be able to be used as a cable for the second PHY, and vice versa.Type: GrantFiled: December 28, 2006Date of Patent: August 20, 2013Assignee: Broadcom Israel Research, Ltd.Inventors: Eliezer Aloni, Uri Elzur, Predrag Kostic, Klaus Friedrich

Patent number: 8477625Abstract: The method of selecting a wireless access telecommunication network in a global link between a first terminal (18) and a second terminal (12) comprises the steps of furnishing context information related to a set of at least one terminal (12, 18) called context taken from the first and second terminals, and in determining the network selected from context information from the set of context terminals (12, 18) by following a set of predetermined rules. The context information of at least one reference terminal taken in the set of context terminals includes information related to a local environment of the at least one reference terminal (12) and the determination of the selected network depends on information related to the local environment of the at least one reference terminal (12).Type: GrantFiled: July 6, 2007Date of Patent: July 2, 2013Assignee: France TelecomInventors: Usman Javaid, Djamal-Eddine Meddour, Toufik Ahmed

Patent number: 8467403Abstract: Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with the coordinated updating of forwarding information bases (FIBs) in a multistage packet switching device, which performs at least lookup operations on multiple different FIBs in determining how to forward a packet. One embodiment uses lookup operations on two different FIBs, with these being an ingress FIB on an ingress line card and an egress FIB on an egress line card. In response to a change in the forwarding information for a stream of packets, the egress FIBs are first updated to include both the old and new forwarding information. After all egress FIBs have been updated, the ingress FIBs are updated to use the new forwarding information. This update procedure is designed to eliminate loss or duplication of packets induced during the updating of these FIBs to use the new forwarding information.Type: GrantFiled: April 29, 2010Date of Patent: June 18, 2013Assignee: Cisco Technology, Inc.Inventors: Yuri Tsier, Parag Kumar Jain, Clarence Filsfils, Sami Boutros, John H.

Patent number: 8437360Abstract: A CMTS or other data aggregation component having a DHCPv6 relay agent extracts a Media Access Control (MAC) address of an end device from a data packet received from an end device. A DHCPv6 data frame is created for transmission to a DHCPv6 server. The MAC address may be inserted into a specific option of the DHCPv6 data frame, where data in the option may not be processed by the server and are echoed back to the aggregation component or CMTS. The DHCPv6 data frame is transmitted to the DHCPv6 server. The component receives a response message from the server that may contain the MAC address or similar client hardware address as it was sent to the server by the network component. The network component may determine an outgoing port interface from which the response message should be sent, utilizing the MAC address and an interface bundling table. In this manner, interface bundling may be enabled.Type: GrantFiled: November 14, 2007Date of Patent: May 7, 2013Assignee: Cisco Technology, Inc.Inventors: Hemant Singh, Madhu Sudan, Shengyou Zeng

Patent number: 8428511Abstract: A network architecture for underground communication using redundant interconnected communication systems utilizes an aboveground master control station to send a status request message to a belowground gateway. The gateway may then, in turn, broadcast a status request message to a plurality of communication hubs located throughout an underground region using each of a plurality of potentially available communication systems. In the event that one of the communication hubs fails to respond over the then-current communication system, the master control station may switch the current communication system being used to a truly available system.Type: GrantFiled: August 10, 2007Date of Patent: April 23, 2013Assignee: Nextel Communications Inc.Inventors: Don Gunasekara, Tom Wilson

Patent number: 8396084Abstract: Systems and methods for point-to-multipoint communications with CAS are provided. In one embodiment, a line unit comprises: an interface to communicate with a node using a first frame structure comprising timeslots, the frame structure transporting signaling bits in an x'th timeslot; the unit coupled another line unit via a communication link, wherein the other unit communicates with another network node using a second frame structure comprising timeslots, the second frame structure transporting signaling bits via its x'th timeslot. Payload timeslots for a first frame received from the other line unit are mapped from the second frame structure to payload timeslots of a second frame using the first frame structure and transmitted via the interface. The x'th timeslot for each of the first and second frame structures are formatted in a multiframe structure comprising a schedule of signaling bit locations allocated to signaling bits corresponding to a designated payload timeslot.Type: GrantFiled: March 5, 2012Date of Patent: March 12, 2013Assignee: ADC DSL Systems, Inc.Inventor: Joe Polland
