  • Patent number: 10320648
    Abstract: Methods and apparatus are disclosed for analyzing network performance of a network comprising network nodes. The method may comprise: obtaining probe measurements by sending probe test-messages via a path from a testing node to a first target node, and also by sending probe test-messages via a path from the testing node via the first target node to a subsequent target node, the probe measurements relating to a network performance characteristic in respect of the paths taken by the probe test-messages and probe response-messages associated therewith and being dependent also on local processing of the probe test-messages at the respective target nodes; comparing the probe measurements; in dependence on the comparison, assigning a weighting in respect of the first target node indicative of whether it is deemed likely to be providing reliable or unreliable results; and determining a network performance analysis measure dependent on the probe measurements and on the weighting.

  • Patent number: 10320647
    Abstract: Information received from disparate individual monitors that are concurrently measuring a predetermined property of a predetermined resource in a network are compared in a reliability computation engine to compute a metric of the degree of similarity between their measurements, and thus to determine a measure of the reliability of one or more of the individual monitors. This information can be used by a provisioning engine to select or reject individual resources for use in meeting service requirements on the basis of the reliability of the reports of their performance, as well as the reported performance itself. Monitors identified as unreliable can also be reported to a fault diagnosis function.

  • Patent number: 10320444
    Abstract: An optical network is disclosed which includes an optical fiber shared by a plurality of transmitters using code division multiple access techniques. The transmitters are connected by tributary optical fibers to the shared optical fiber. In code division multiple access techniques, each communication is encoded with a distinctive code which enables a receiver to extract the communication intended for it from amongst communications intended for other receivers. It is found that synchronizing the communications on the optical fiber improves the ability of a receiver to extract the communication intended for it. Injecting an optical pulse signal into the optical network, and using the tributary optical fibers to carry the clock signal to the transmitters provides an inexpensive method of synchronizing the transmitters which feed signals onto the optical fiber. The technology is of use in optical networks, and other transmission line networks, and is well-suited to use in local area networks.

  • Patent number: 10320770
    Abstract: An access control system is provided to provide a core server to authenticate the permissions of users to access services provided by other operators. The provision of a single core server allows many-to-many access agreements to be mediated and maintained for effectively than by operating individual one-to-one access permissions. This allows updates to access permissions to be handled by the operator responsible for the user or service in question, without the need to directly co-operate which each and every service involved. When an access attempt is made through a user interface (10) to access a service provided by another user (20), the service provider (21) refers the request to a core server (30) for authentication, and the core server (30) instructs the user to identify an identity provider (32) with which he is authenticated (step 63). Details provided by the user may be stored by the core server (30) for one or more subsequent uses.

  • Patent number: 10305716
    Abstract: In a method of transmitting data between a transmitter and a receiver via two pairs of wires in a differential mode, the method comprises transmitting, from the transmitter to the receiver, related signals onto the two pairs of wires in respect of each tone in a first subset of tones and processing the received signals in dependence upon estimated channel transfer functions associated with both direct and crosstalk channels. The method further comprises transmitting, from the transmitter to the receiver, unrelated signals onto the two pairs of wires for each tone in a second subset of the tones, the unrelated signals being vector precoded before transmission and wherein a cut-off frequency and/or tone demarcates between the first and the second subsets of tones.

  • Patent number: 10284920
    Abstract: There are described methods and systems for distributing content in a network, in particular a multicast network. One method includes delivering content from a source to a destination in a content delivery network. A request for an item of content is received and a first multicast stream is identified or established, the first multicast stream comprising a first copy of the content. At least one second multicast stream is also identified or established, the second stream comprising a second copy of the content. The second copy of the content is time-shifted by a time, M, from corresponding portions of the first copy of the content. The content is then delivered to the destination using both the first and the second multicast streams.

  • Patent number: 10277272
    Abstract: This invention relates to a method of managing a digital subscriber line, where classification for a potential fault on a line is generated. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, the line is flagged as experiencing a potential fault. Further measurements from weather sensors are gathered, and correlated with the SNR margin characteristics. The resulting correlation is used to generate a classification of a potential fault on the line. This can then be used to more specifically direct diagnosis and further testing.
