Device for detecting congestion in e.g. communication network for e.g. communication unit, has analysis unit determining whether time difference data satisfies rule for determining whether communication network is subject to congestion

摘要

The device (D) has a control unit (MC) that is utilized for storing messages that are transmitted periodically. The control unit stores time difference data of a periodic message part. An analysis unit (MA) is utilized for determining whether time difference data satisfies a rule for determining whether a communication network (R) e.g. vehicle area network, is subjected to congestion when a storage area comprises time difference data of periodic messages of associated group.
