Description
Summary: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, composed of the sustainable cell rate 1/ T SCR and the intrinsic burst tolerance TIBT , is defined with respect to an algorithmic characterization, the generic cell rate algorithm (GCRA). This method makes source parameter enforcement straight forward. Unfortunately, the current standards of IMS did not include this SCR concept. In this paper, we investigate the issues involved in QoS parameters and suggest the SCR in SDP.
