Patent ID: 7957419

Claim:
A method for managing bandwidth in a synchronous communications network comprising a plurality of nodes, said network implementing a first clocking which defines a data-processing cycle comprising a determined number of virtual channels corresponding to time slots, said data-processing cycle being defined by a current data-processing frequency, said plurality of nodes comprising at least one transmitter node associated with at least one generator application generating data that has to be transmitted to at least one destination node, each generator application being associated with at least one virtual channel for transmitting its data, said method comprising the following steps, performed for a given generator application: a) determining a set of virtual channels, within said data-processing cycle, for transmitting the data of the given generator application according to the first clocking defined by the current data-processing frequency, the set of virtual channels determined being filled one by one from a first to a last virtual channel; b) determining a rate of use of the last virtual channel of the set of virtual channels determined for transmitting the data of said generator application; c) adjusting said current data-processing frequency, as a function of said rate of use of said last virtual channel, enabling an adjusted data processing frequency to be obtained; and d) allocating an integer number of virtual channels for transmitting the data of said generator application, as a function of said rate of use of said last virtual channel.
