Minimum cell rate allowed. The PCR and the MCR define the allowable cell
rate (ACR) range. The MCR is the rate at which the source is always allowed to
send. The MCR shall include bandwidth occupied by both data cells and the
inrate RM cells.
Range: 10–38328 cps
Peak cell rate allowed. The PCR and the MCR define the allowable cell rate
(ACR) range. The PCR shall include bandwidth occupied by both data cells and
the inrate RM cells.
Range: 10–38328 cps
Initial cell rate is the rate to which a source should send initially and after an
idle period.
Range: 10–38238 cps
Rate increase factor controls the amount by which the cell transmission rate
may increase upon receipt of an RM cell. The additive increase rate
AIR=PCR*RIF. RIF is a power of 2, ranging from 1/32768 to 1.
Range: 1–32768
Rate decrease factor controls the decrease in the cell transmission rate. RDF is
a power of 2 from 1/32768 to 1.
