  • Assisted determination of data flows in communication/data networks
    Patent number: 8423633
    Abstract: In one embodiment, a method of determining data traffic flow in a network includes: (a) selecting a location within the network for providing a data collector adapted to process data pertaining to the network data traffic flow; (b) determining the expense or level of data capture that would result from providing the data collector at the selected location; and (c) providing the data collector at the selected location dependent on the determination in step (b) and predetermined expense or data capture targets.

  • Traffic flow determination in communications networks
    Patent number: 8194546
    Abstract: A method of determining traffic paths between one or more source-destination node pairs in a communications network, comprising starting from a first set of paths between said source-destination node pairs, determining a second set of paths between said source-destination node pairs while taking into account a set of constraints, such that said second set of paths emulates said first set of paths.

  • Method and system for constraint-based traffic flow optimisation system
    Patent number: 7920468
    Abstract: A method of calculating traffic values in a communications network (1), the communications network comprising a plurality of nodes (2,4), the nodes being connected to one another by links (24), the method comprising: (a) obtaining traffic data measurements (102) through said nodes and/or links in an initial scenario as input data; (b) deriving a traffic flow model for a modified scenario using a plurality of constraints describing the interdependency of said initial to said modified scenario (116); and (c) calculating values and/or upper and lower bounds of traffic values for said modified scenario from said traffic flow model using said input data (118).

  • Estimating traffic values or intervals for network topology and network behaviour
    Patent number: 7802012
    Abstract: A method of estimating traffic values or intervals in a communications network, the network comprising a plurality of nodes being interconnected by links, the method comprising the steps of (a) obtaining traffic data through the nodes or links as input data; (b) obtaining network data relating to the network topology and network behaviour; and (c) estimating the effect of a modification of the communications network and/or its behaviour be calculating traffic information between a selected first and a selected second node of the network using the input data.
