  • Method and apparatus for shortest path bridging of multicast traffic
    Patent number: 9455900
    Abstract: Methods, system and apparatus for determining shortest path bridging (SPB) within a communications network.
    Type: Grant
    Filed: April 8, 2014
    Date of Patent: September 27, 2016
    Assignee: Alcatel Lucent

  • Method and Apparatus For Gateway Selection In Multilevel SPB Network
    Publication number: 20150036508
    Abstract: A manner facilitating automatic selection of active gateway for communication between nodes in levels of a multilevel SPB network that adapts automatically to changes in network topology and allows autonomous operation within levels. When more than one node is eligible to act as the gateway, selection criteria, for example, a metric representative of the cost associated with choosing a node as gateway is used to select the active gateway.

  • Route selection for path balancing in connection-oriented packet switching networks
    Patent number: 6195354
    Abstract: In a methodology for route selection for path balancing in a connection-oriented packet switching network, a comparison is made of the measures of utilizations of a network resource by at least two links of a link group in the network, and at least one link is identified as a candidate for carrying traffic path based on the comparison. Network traffic path on the link is then moved to the candidate link to reduce variation in the utilization of the network resource by each of the links.

  • Bandwidth correlation means for paths in connection-oriented packet switching networks
    Patent number: 5848055
    Abstract: An alternate path can be established in a connection-oriented packet switching network by correlating the bandwidth reservation of this alternate path with the bandwidth reservation of an active path on trunks through which both paths pass. The alternate path that is established can have one or more of a number of different attributes that vary from the attributes of the active path. The alternate path is established in a connection-oriented network with bandwidth correlation in three stages: a keying stage, a correlation stage and, a transfer stage. An alternate path may be established without a double reservation of bandwidth, thus making efficient use of limited network resources.
