Abstract
There is assigned to each virtual circuit a period (pm) corresponding to the theoretical minimum period between two consecutive cells of the virtual circuit and a maximum time limit (dm). The imaginary time of emission on the output multiplex of the last cell belonging to each virtual circuit is stored, and, upon the arrival of a new cell of a virtual circuit, a threshold time calculated by adding its actual time of arrival and the maximum time limit is compared with the imaginary time of emission expected of the new call in the course of being processed, the time being calculated by adding the imaginary time of emission of the last cell emitted and the minimum period (pm). If the result of this comparison shows that the threshold time is earlier than the imaginary time of emission expected (tde+pm), the incoming cell is not re-emitted, whilst, if it shows that the threshold time is later than the imaginary time of emission expected (tde+pm), it is emitted on the output multiplex, the imaginary time of emission of the incoming cell then being calculated, then stored in relation to the virtual circuit to which the incoming cell belongs.
