  • Treatment of data in networks
    Patent number: 8797887
    Abstract: Data networks, nodes making up parts of data networks, and information are related to the characterization of paths taken by data travelling between nodes in the networks. Path characterization information is arranged to be conveyed to nodes such that it may be used by nodes subsequently forwarding data. In particular, the invention relates to nodes receiving such path characterization information from upstream nodes, deriving therefrom information indicative of characteristics of a path downstream of said nodes, and using such information to make informed decisions such as routing decisions when forwarding data onward in data networks.
    Type: Grant

  • Networks
    Patent number: 8391152
    Abstract: Data networks and nodes making up parts of data networks are arranged to derive information relating to the characterization of paths taken by data travelling between nodes in the networks. Path characterization information is fed back from a receiver of data to a provider of data, and informs nodes subsequently forwarding data of characteristics of the downstream path. Also described are routing and related controlling nodes and methods for using such path characterization information to make informed routing and other decisions when forwarding data in a data network.
