Abstract

Method for the control of the cell flow in a telecommunication system in ATM technique, according to the so-called 'Leaky Bucket' principle, where to each active connection (VC/VP) a current value (VLB) is associated, increased by a first quantity (INC) and decreased by a second quantity, following the arrival of an information cell relating to the connection. Said value (VLB) is compared with a reference threshold (S) to decide if the cell has to be sent or not. The decrease is equal to the product of a third quantity (DEC) and the difference between the absolute time (CLK) and the time (LST) of the previous updating of said current value (VLB). The method is implemented by means of one unit (PU) including two control units (CC, MC), an arithmetic unit (AU), a register file (RF) and an input/output unit (I/O).
