Abstract
To manage band allocation as a function of occupancy loading on a local network with high quality of service, the invention proposes a decentralized management protocol distributing allocation at all times by adapting the load of application streams to be transmitted to the bandwidths available on the network. According to the invention, the management method which includes token bucket filters as an output interface between the application stations and the transmission bus, comprises the steps of each network element broadcasting to each other network element, by connections through the protocol, reserved bandwidth parameters for best effort mode and for privileged modes concerning data streams; the network element establishes a parameter measuring the bandwidth available for its connection on the basis of a table of parameter values transmitted in the preceding step; and the network element concerned by the measurement parameter adjusts the value of its best effort parameter as a function of the variation in its available bandwidth parameter so as to preserve a positive or zero value therefor.
