摘要： The invention provides a method and apparatus for detecting communication channel delay asymmetry between transmission line protection devices. The method comprises: calculating, repeatedly, clock disparity between clocks of the protection devices and communication delays at different paths of the communication channel; comparing the latest calculated clock disparity and communication delays with previously calculated clock disparities and communication delays, respectively; determining a channel switching has happened if a change of the calculated clock disparity exceeds a first threshold, or a change of the calculated communication delays for any path exceeds a second threshold; and determining the channel delays as asymmetrical if a difference between the calculated communication delays of the different paths after the channel switching exceeds a third threshold.

摘要： Methods and arrangements are provided for handling, within a communications system comprising a distributed domain (301) and a central domain (303), electronic records that contain predictions of the outcome of a certain incident. Within the distributed domain (301) there is generated (304), before the outcome of the incident is known, a multitude of electronic records that contain predictions of the outcome of the incident. The electronic records are conveyed (305) from the distributed domain (301) to the central domain (303). After the outcome of the incident is known, the central domain (303) finds out (306) which of the electronic records, if any, contain correct predictions of the outcome of the incident. Each of the electronic records is furnished (304, 401, 502, 902, 1202, 1911), within the distributed domain (301), with a cryptographically protected proof of a certain moment of time associated with the generation of the electronic record. The central domain (303) accepts (306, 1430, 2011) only those of the electronic records conveyed thereto as valid for which the cryptographically protected proof of a certain moment of time associated with the generation of the electronic record shows that said certain moment of time was not later in time than a certain time limit.
