The Sustained Cell Rate Margin Factor (SCRMF) is used in
Connection Admission Control (CAC) of VBR connections to
vary the weight given to the difference between Sustained
Cell Rate (scr) and Peak Cell Rate (pcr) specified in the
traffic contract. When calculating the equivalent bandwidth
offered by a connection, SCRMF is used as follows:
eqBw = scr + ((pcr - scr) * rcacVbrScrmf) / 100
