Abstract
In a network including an optical link transporting packet streams of successive optical packets separated by voids, the station includes a transmission device (13) coupled to the link at an insertion point in order to inject optical packets into the link. At a detection point on the link, upstream of the insertion point, a detection device (11) observes the packet streams transported to this detection point. As a function of this observation each packet awaiting transmission and transmitted by the transmission device (13) causes the formation at the insertion point of a downstream packet stream containing the transmitted packet interposed between first and second packets delimiting a void of the upstream stream. The detection device (11) forms a transmission control signal (ACK) such that in the event of transmission as a function of this control signal, any transmitted packet is attached to at least one of the first and second packets.
