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/TSCR and the intrinsic burst tolerance τIBT, 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 (TSCR, τIBT) 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
