Abstract:
Process for spacing ATM cells travelling through an ATM switch and emitted by ATM sources multiplexing diverse profiles destined for one or more networks of specified bit rate, characterized in that it consists: in aggregating the sources emitting cells destined for the same network and in giving the sources a standardized global profile of the type with constant bit rate CBR or of the type with variable bit rate VBR, the sources being assigned a specified priority,in taking into account the priorities of each of the sources so as to allow specified qualities of service,in combining sources multiplexing CBR and VBR profiles so as to obtain a source having a globally VBR or CBR profile, whilst also preserving the characteristics of the sources with CBR profile in the case of a globally VBR profile,in sharing the passband of the physical link supporting the streams of outgoing cells, between the VBR and CBR profiles, and in allotting the remainder of the passband which is not used up by the above VBR and CBR profiles to so-called complementary sources of undefined bit rate profile UBR, andin adapting the bit rate of the sources with globally VBR or CBR profile to the bit rate of a specified physical link through which the outgoing cells must travel in order to access a specified network.
