Abstract

In a digital communication system in which the information is transmitted by successions of bits termed packets, stations may be called upon to perform the function of a relay between other stations. The stations which may be called upon to perform the function of a relay comprise: a checking device which merely checks the address code of a packet received; an eliminating and switching device which either destroys the packet (doubtful address code) or orients the packet toward receiving means pertaining to the station (address code identical to the code of the station) or toward the station corresponding to the address code by passing through a transit memory; and information producing means for producing packets within the station. The contents of the transit memory are transmitted in priority by the station. The packets produced within a station are transmitted in the gaps between the packets coming from the transit memory and in an order which is a function of a classification between the priorities allocated to the information producing means of the considered station.
