DATA NETWORK AND METHOD FOR SCHEDULING DATA TRAFFIC IN DATA NETWORK

A data network, particularly on board of an aircraft such as a cabin network or a cargo bay network, comprises at least one network communication line, a plurality of network devices connected to the at least one network communication line, and at least one traffic scheduler interconnected between at least some of the plurality of network devices and the at least one network communication line. Each of the plurality of network devices is configured to feed communication messages into the at least one network communication line. The at least one traffic scheduler includes a plurality of message queues, a message valuation module and a queue dispatcher coupled to the plurality of message queues. The message valuation module is configured to assign a message value parameter to communication messages received from the at least some of the plurality of network devices and to queue up the communication messages to respective ones of the plurality of message queues depending on the assigned message value parameter. The queue dispatcher is configured to dispatch the communication messages in the plurality of message queues depending on a priority assignment of each of the plurality of message queues.
