Patent ID: 8213454

Claim:
A method of managing the transmission of data streams generated by a terminal of a multiple-access shared communications network, the communications network including a plurality of terminals connected to a single channel that passes all data streams generated by the plurality of terminals, said data streams being structured in data frames and comprising at least one priority data stream and at least one non-priority stream, wherein the method comprises the steps of: monitoring, by said terminal, of said multiple-access shared network to detect data frame collisions of data frames transmitted by said terminal in the single channel; determining a congestion state of said multiple-access shared network based at least in part on a rate of data frame collisions detected by said terminal in the single channel and a number of priority data frames retransmitted more than N times by said terminal during a collection period, where N is a predetermined natural number; and managing the transmission by said terminal of said priority and non-priority data streams as a function of said congestion state such that a rate at which said priority data streams are transmitted is determined at least in part by a first method and a rate at which said non-priority data streams are transmitted is determined at least in part by a second method, the second method being different from the first method.
