Patent number: 9154422Abstract: Apparatus and methods for policing flows of data units (15) along a path in a data network in dependence on congestion indications associated with said data units indicating whether or not said data units have experienced, or are expected to experience, congestion on the path, said apparatus and methods allowing for a high but not unlimited short-term burst rate (wST) of data units having congestion indications associated therewith, the short-term burst rate being high when compared with a long-term average rate (wLT) at which data units having congestion indications associated therewith may be forwarded without the data units being subjected to a policing action such as dropping, delaying or marking for possible sanction.Type: GrantFiled: March 25, 2010Date of Patent: October 6, 2015Assignee: British Telecommunications PLCInventors: Arnaud Jacquet, Tobias Moncaster, Robert J Briscoe

Patent number: 9130768Abstract: Methods and apparatus for providing path characterization information relating to a network characteristic such as network congestion to nodes in a data network using data units being forwarded from a source to a destination via a plurality of nodes in the network, the method comprising: receiving, at a first proxy node, data units from a source, each data unit comprising a destination indication indicative of an intended destination; identifying, in respect of an intended destination indicated, a second proxy node in the network to which data units may be forwarded before being forwarded to the intended destination; and forwarding a first and at least one subsequent data unit from the first to the second proxy node via ‘one or more intermediate nodes; the method further comprising assigning conditions to path characterization metrics in respect of data units traversing a path across the network from the first to the second proxy node, the initial condition being dependent on information received by the firstType: GrantFiled: March 16, 2010Date of Patent: September 8, 2015Assignee: BRITISH TELECOMMUNICATIONS PUBLIC LIMITED COMPANYInventors: Tobias Moncaster, Arnaud Jacquet, Alan P Smith, Robert J Briscoe

Patent number: 8880681Abstract: Methods and systems for assigning information indicative of a network characteristic to one of a plurality of data units traversing a path across a network, said data units having associated therewith values indicative of said network characteristic, said path having at least one portion passing through a lower-capability region and at least one portion passing through a higher-capability region, said lower-capability region being a region in which information indicative of said network characteristic may be represented by values having a first resolution, and said higher-capability region being a region in which information indicative of said network characteristic may be represented by values having a second resolution, said second resolution being greater than said first resolution, said one data unit being a data unit entering said higher-capability region.Type: GrantFiled: January 14, 2009Date of Patent: November 4, 2014Assignee: British Telecommunications public limited companyInventors: Tobias Moncaster, Robert J Briscoe, Arnaud Jacquet, Alessandro Salvatori

Patent number: 8755282Abstract: 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.Type: GrantFiled: March 16, 2011Date of Patent: June 17, 2014Assignee: BRITISH TELECOMMUNICATIONS public limited companyInventors: Alan P Smith, Arnaud Jacquet, Robert J Briscoe, Andrea Soppera, Stephen C Appleby, Tobias Moncaster
