BUFFER DIMENSIONING FOR DELAY-SENSITIVE AND LOSS-SENSITIVE TRAFFIC

Multiplexing of delay- and loss-sensitive traffic requires a common an alytical framework for buffer dimensioning, buffer sharing schemes, as well as buffer entry and exit priorities. This paper performs a relev ant study by employing discrete-time queueing techniques, appropriate for the small buffer sizes envisaged in ATM technology. The model, sol ution method and relevant metrics are presented. The numerical results are critically reviewed. These give rise to a buffer dimensioning alg orithm. Loss requirements are primarily satisfied. However, an accepta ble upper bound for the delay of the delay-sensitive traffic can also be accommodated.
