Description
Peak Cell Rate
The cell rate that may never be exceeded by
the source. After negotiation in the network,
the PCR is constant for each connection and
may be supervised by policing.
Minimum Cell Rate
The cell rate that the source may send at any
time.
Inititial Cell Rate
The cell rate at which the source may send at
start time and after a long inactive time,
defined by the global constant ADTF (ACR
Decrease Time Factor).
To configure, see
Transient Buffer Exposure
The number of cells the source may send
without receiving BRM cell feedback. Must be
adapted to match the buffer space allocated to
the VC in the first downstream switch.
Used in ICR and CRM calculation, see formula
in
Fixed Round Trip Time
The estimated delay on a full round trip, from
sending FRM until receiving BRM, including
propagation and queueing delays.
Used in ICR and CRM calculation, see formula
in
Rate Increase Factor
Used in the ACR calculation for the relative
rate marking mechanism.
