Abstract
The invention relates to a communication device and a method of sending data over a communication network. The communication device includes a controller for accessing the network using contention type access mechanism based on computation of back-off values, and includes a plurality of traffic queues for serving data traffic at different priorities. The controller includes a plurality of back-off engines, each associated with one traffic queue and configured to compute a back-off value in accordance with the priority of the associated traffic queue. One or more back-off engine may be adjusted to prevent the back-off value of such back-off engine to reach zero. When an access to the network is obtained for the device. a traffic queue may be selected based on its associated back-off value, and data may be transmitted from the selected traffic queue.
