  • Method and apparatus for applying uniform hashing to wireless traffic
    Patent number: 9270561
    Abstract: A method, computer readable medium and apparatus for hashing wireless traffic are disclosed. For example, the method hashes the wireless traffic uniformly by a plurality of probe servers based on at least one first key to provide a plurality of streams, and hashes at least one output stream of each of the plurality of probe servers uniformly based on at least one second key to provide a plurality of output streams. The method then provides the plurality of output streams to at least one aggregator server.
    Type: Grant
    Filed: May 20, 2014
    Date of Patent: February 23, 2016
    Assignee: AT&T Intellectual Property I, L.P.

  • System and method for deriving traffic demands for a packet-switched network
    Patent number: 7796619
    Abstract: The present invention is directed to a method and system for deriving traffic demands for a packet-switched network. A novel model of defining traffic demands as a volume of load originating from an ingress link and destined to a set of egress links enables support for traffic engineering and performance debugging of large operational packet-switched networks.

  • Traffic engineering system and method
    Publication number: 20020103631
    Abstract: The present invention is directed to a novel system and method for traffic engineering in a packet-switched network, such as an Internet Protocol (“IP”) based backbone network. A global view of the network is constructed utilizing a network data model that can be readily constructed from the balkanized network information associated locally with the individual elements in the network. The data model, in turn, can be utilized to support useful traffic engineering tools such as routing modeling and visualization.
