Abstract
A process for spacing ATM cells traveling through an ATM switch and emitted by ATM sources multiplexing diverse profiles destined for one or more networks of specified bit rate. First, the sources emitting cells destined for the same network are aggregated and given a standardized global CBR or VBR profile, the sources being assigned a specified priority. Next, the priorities of each of the sources are taken into account so as to allow specified qualities of service, and the sources are combined by 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. Sharing the passband of the physical link supporting the streams of outgoing cells, between the VBR and CBR profiles, then takes place, and the remainder of the passband which is not used up by the above VBR and CBR profiles is allotted to so-called complementary sources of UBR profile. Lastly, sources with globally VBR or CBR profile are adopted to the bit rate of a specified physical link through which the outgoing cells must travel in order to access a specified network.
