摘要
The invention relates to a method to ensure the quality of preferred (communications) services, especially voice services, in a local data network with different types of services, where data congestion or data collision on a shared transmission medium is treated by a collision detection method and by application of re-transmission rules after detection of data collisions, wherein depending on the type of service, the corresponding data packets are subject to different re-transmission rules and wherein the different re-transmission rules each define a set of different parameters for an algorithm to randomly calculate the backoff time, that a station has to wait after a collision detection, before it re-transmits a data packet affected by the collision, the different sets of parameters comprising each at least the mean of said backoff time, as well as to a local network, a station, a local network controller and a program module therefor.
