Abstract :
A crucial parameter in the design of QoS (quality of service) routers is the periodicity with which the nodes have to broadcast messages about possible changes in the bandwidth availability of the links. A simple method for the adaptive control of this broadcast process in QoS routers is presented. In particular, the method modifies the triggering condition of the update process with the aim of stabilising the overload provoked by the update messages. The benefits of the method are shown in a realistic network in terms of bandwidth loss probability and update rate.
