Description
AVT-VS/VD configure
Table 3-53
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.

configure
Minimum Cell Rate
The cell rate that the source may send at any
time.
AVT-VS/VD configure
Table 3-53
TPi
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 Section 3.5.1.9
configure Transient Buffer Exposure
in
The number of cells the source may send
connection without receiving BRM cell feedback. Must be
handler adapted to match the buffer space allocated to
SW
the VC in the first downstream switch.
Used in ICR and CRM calculation, see formula
in Section 3.5.1.9
configure Fixed Round Trip Time
in
The estimated delay on a full round trip, from
connection sending FRM until receiving BRM, including
handler propagation and queueing delays.
SW
Used in ICR and CRM calculation, see formula
in Section 3.5.1.9
AVT-VS/VD 1/32768
Table 3-53
Rate Increase Factor
Used in the ACR calculation for the relative
rate marking mechanism.
