Abstract

The sustainable cell rate (SCR) was introduced by the ATM Forum as a means of characterizing the statistical activity of ATM VBR connections. The SCR traffic descriptor (SCR-TD), composed of the sustainable cell rate 1/T_SCR and the intrinsic burst tolerance τ_IBT, is defined with respect to an algorithmic characterization, the generic cell rate algorithm (GCRA). This method makes source parameter enforcement straightforward. Unfortunately, the current specification of the SCR-TD is incomplete, leaving the source with an infinite number of (T_SCR, τ_IBT) couples to choose from, This ambiguity could bear a negative impact on network efficiency. The authors investigate the issues involved in selecting suitable SCR-TD values for a given source, both from a user´s perspective and from a networking point of view
