Patent number: 11290362Abstract: Diagnostic test results are obtained in respect of local area networks (LANs), the LANs having user-devices located therein having interfaces and being operable to communicate via those interfaces and via a LAN gateway device with remote devices in a communications network outside their respective LANs. A method comprises comparing performance measures obtained in respect of communication flows with a performance threshold whereby to identify communication flows whose performance measures are indicative of performance below a predetermined level, and for any such communication flows, obtaining a diagnosis in respect of the LAN in question in dependence on a comparison of the performance measure obtained in respect of the identified communication flow and performance measures obtained in respect of other communication flows, the diagnosis being obtained in dependence on respective portability levels and network interface types determined in respect of the user-devices involved in said communication flows.Type: GrantFiled: September 6, 2018Date of Patent: March 29, 2022Assignee: BRITISH TELECOMMUNICATIONS public limited companyInventors: Alan Smith, Trevor Burbridge
