  • Patent number: 10575239
    Abstract: In a WLAN with many concurrent users, a wireless access point is configured with information relating to a set of priority devices and when network utilisation exceeds a particular threshold, the wireless access point is arranged to identify a priority device connected to the WLAN, determine a policy for reconfiguring the WLAN to enable better performance to the priority device, and offer the improvements to the priority device. The changes to the WLAN are only applied if a user of the priority device opts to apply the changes thereby changing the WLAN performance in accordance with user requirements.

  • Patent number: 10574743
    Abstract: As data processing requirements of individual client systems A to K change over time, they are allocated service from physical datacentres X, Y, Z according to the existing capabilities of the data centres requirements of the client systems, thus transferring client systems between cells controlled by individual data centres. This avoids the complex process of adapting the individual physical datacentres' capabilities to the changing requirements of the client systems to which they were originally allocated: thus the capabilities, and not the mappings, are maintained and the mappings, not the capabilities, are dynamic, so as to optimise the allocation of client systems to cells. It also minimises the number of clients having to work to more than one datacentre, which leads to delays in processing as the datacentres need to communicate with each other.

  • Patent number: 10567937
    Abstract: An application deployment manager 8 associated with an associated Mobile Edge Computing server receives a notification (step 222) of a newly-attached terminal, and queries a database 60 (step 223) to identify any computing applications the terminal is associated with, and interrogates an application platform 12 and an update record 72 to determine whether the current version of each required service is currently hosted on the platform 12 (steps 225, 250). The application deployment manager 8 then retrieves any programme data not already hosted on the application management system (step 227) for installation ready for use by the terminal 2.

  • Publication number: 20200053082
    Abstract: A computer implemented method for access control for a consumer accessing a restricted resource in a network connected computer system, the method: including receiving a continuous sequence of data records relating to use, by the consumer, of the restricted resource, the resource being accessed by the consumer over an access network; continuously comparing the data records with an access control policy for the restricted resource; in response to a determination that the behavior is non-compliant with respect to the policy, generating and communicating a shared secret to the consumer, the shared secret being communicated via a communications channel other than the access network; receiving a response to a challenge from the user via the access network; and notifying the computer system that access to the resource by the consumer should be precluded based on a comparison of the response to the challenge and the shared-secret.

  • Publication number: 20200044734
    Abstract: An optical network including a processing device configured to receive from photodetectors, information indicative of a time period between loss of light received through a first optical fiber and loss of light received through a second optical fiber. The first optical fiber has a first latency and the second optical fiber has a second latency. The first optical fiber and the second optical fiber extend along a common path through the optical network: a first end of the path being defined by the photodetectors and a second end of the path being defined by a second location in the optical network. The processor is configured to calculate, based on the timing information and a difference in latency between the first optical fiber and the second optical fiber, a distance along the common path from the photodetectors to an event resulting in the losses of light.

  • Patent number: 10554300
    Abstract: The present invention provides a method of indirectly determining the optical signal-noise ratio of an optical fibre communications link. In a test environment, the relationship between OSNR and pre-FEC BER (forward error-corrected bit error rate) is determined for a particular type of optical transponder. When a transponder of that type is connected to an optical communications link then the pre-FEC BER can be measured and the OSNR inferred from the pre-determined OSNR-BER relationship. The OSNR value can then be used to select a transponder modulation format or other transmission parameters.

  • Patent number: 10554578
    Abstract: Method and systems for managing QoS models for traffic flows in a network are described. In particular, the method includes storing the QoS models and analyzing at least one of the QoS models to determine whether the QoS model satisfies a suitability test. One or more QoS models are then selected based on the analysis and these selected models are offered to a client for use with a traffic flow in the network. In one embodiment, the method may be implemented based on a query from a client requesting reservation of network resources for a traffic flow. The analysis may be based on a characteristic of the or each QoS model, of the client, of a query received from the client requesting reservation of network resources for the traffic flow or of the network or an operator of the network.

  • Patent number: 10531363
    Abstract: A method of controlling wireless Internet access is disclosed. A problem with conventional wireless Internet access is that users of wireless Internet access devices such as smartphones, tablets and laptop computers are often presented with an indication of the availability of an Internet connection, but find when they try to use that connection that it is of a disappointing quality. In some cases, the disappointing quality is caused by a poor radio link between the wireless device and an access point. In order to alleviate the problem in those cases, a method of controlling wireless Internet access is disclosed in which the attachment of a wireless device to a wireless network triggers the access point providing that wireless network to send the wireless device a series of test frames.
