摘要： Path characterization information is provided to a data sender relating to a network characteristic such as congestion experienced by data units traversing a path across a data network from the data sender towards one of a plurality of data receivers. The data units have associated therewith information indicative of the network characteristic. The path is traversed by the data units having at least a first path portion between the data sender and a proxy node along which data units may traverse conveying a measure indicative of the network characteristic that is representable by any of a first set of codepoints. The data receivers are operable to provide data acknowledgement units in respect of data units they receive via a second path portion in which information indicative of the network characteristic may only be representable using codepoints of a second set of codepoints having less codepoints than the first set.

摘要： A network channel is used as a waiting channel, wherein members of a group other than a first member join the waiting channel while performing an action or process, and then leave the waiting channel once the action or process has been performed. Once all of the members have left the waiting channel the first member of the group then performs an action or process. In order to indicate to the first member that all of the other members have left the waiting channel, a protocol such as the Multicast Source Notification of Interest Protocol (MSNIP) may be used.

摘要： The invention relates to data networks, to nodes making up parts of data networks, and to information relating to the characterisation of paths taken by data travelling between nodes in the networks. Path characterisation 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 characterisation 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.

摘要： Flow in a data network is policed by determining a measure of greediness of a flow through a node, comparing the measure of greediness with a measure indicative of acceptable greediness dependent on the expected greediness of a compliant flow experiencing substantially similar path conditions, and designating the flow for possible sanction in the event that the greediness is not in accordance with the acceptable greediness. Such allows for the policing of a data network when one or more fields in a data packet that carry information relating to a characterization of an end-to-end path and/or a downstream path of the data packet are used in order to police the data network.
