  • Publication number: 20180152507
    Abstract: A method includes receiving profile information for a network. The method also includes determining a network configuration based on at least a constraint associated with at least one of a network session or a hardware capacity of a hardware platform of the network and a number of sessions that the network configured based on the network configuration can support. The method also includes configuring the network based on the network configuration.

  • Patent number: 9634847
    Abstract: A method and system for multicasting IPTV channels includes using both a designated and a redundant network routing device. When the designated routing device detects that an MCDN network connection to an IPTV multicast source is unavailable, the designated routing device reduces its designation priority to a lower value. A message is sent to the redundant routing device with an instruction to increase its designation priority to a higher value. After the designation priorities have been modified, the designated routing device may serve as a new redundant routing device, while the redundant routing device may serve as a new designated routing device. The routing devices may remain in the new configuration, even after interrupted network connections are restored.

  • Patent number: 9571895
    Abstract: A method and system for multicasting Internet-protocol television (IPTV) channels is disclosed. In order to receive desired IPTV channels, a first-hop router (FHR) may send a join message to a last-hop router (LHR) establishing multiple paths across a backbone network. The join message may specify mapping at least one virtual IPTV channel to a plurality of multicast channels, along with the desired IPTV channels. The multicast channels may then be transmitted in a round-robin manner over the multiple paths from the LHR to the FHR. A number of virtual IPTV channels may be modified in response to determining a loading profile over the multiple paths to maintain a balanced load among the multiple paths.

    Abstract: Systems, methods, and articles of manufacture to determine connectivity are disclosed. An example method includes identifying a radio network controller serving a NodeB, identifying a first connection between the NodeB and an integrated access device, identifying a virtual circuit communicatively coupling the integrated access device and a mobile service node, identifying a second connection between the integrated access device and network termination equipment, identifying a third connection between the network termination equipment and an Ethernet aggregation node, identifying, with the processor, that a pathway between the radio network controller and the NodeB includes the first, second, and third connections, and storing the pathway between the radio network controller and the NodeB.

  • Patent number: 7937483
    Abstract: A system and method of routing data packets is disclosed. In a particular embodiment, the method includes receiving a first Internet Protocol (IP) data packet at a first access port of an access line card within a data router. The method also includes transmitting the first IP data packet from the first access port to a network line card within the data router, via a first trunk port of the access line card. The first access port is coupled to the first trunk port and not coupled to at least one other access port. The method further includes receiving a second IP data packet at a second trunk port of the access line card from the network line card. In addition, the method includes transmitting the second IP data packet from the second trunk port to a second access port of the access line card.

  • Patent number: 7586844
    Abstract: Virtual circuits are dynamically established in a telecommunications network. A cache duration is adaptively determined based on at least one characteristic of the telecommunications network. A virtual circuit is established for a connection between a source and a destination. The virtual circuit is cached when the connection between the source and the destination terminates. The cached virtual circuit is reused when a new connection request occurs during the cache duration. The cached virtual circuit is released after the cache duration when no new connection request occurs during the cache duration.
