Abstract:
A method for controlling a data transfer rate at which coded data are transferred in an asynchronous transfer mode, comprising the steps of:forming said coded data for an ATM adaptation layer;calculating an insertion timing for insertion of a NULL packet;inserting said NULL packet into said coded data of said ATM adaptation layer in consonance with said insertion timing, obtained by the calculation, for said NULL packet; andtransferring, in said asynchronous transfer mode, said coded data of said ATM adaptation layer into which said NULL packet has been inserted,wherein insertion timing P for said NULL packet to be inserted is acquired fromP=.alpha.y/(.alpha.y-x),where .alpha.=47/53, x denotes a coded bit rate for said coded data and y denotes an available bit rate for an asynchronous transfer mode layer.
