QIR
The transmit Quiescent Information Rate (QIR)
parameter. Also known as Initial Cell Rate (ICR),
the rate at which a source should send initially
and after an idle period. The following
configurations apply:
• Units: cells per second
• Applicable connection types: ABRSTD,
ABRFST, ATFST
• Range: MCR-PCR
• Default: 50
• Dependency: ICR >= MCR, VSVD = enable (1)
• Applicable cards: BXM, ASI-T3/E3
% Utilization
The channel percentage of bandwidth utilization.
Bandwidth allocation based on percent utilization
depends on the connection types. The following
configurations apply:
• Units: % percentage
• Applicable connection types:
- UBR: default = 1%
- CBR: default = 100%
bandwidth allocation = PCR(0+1) * % Util
- VBR, ATFR:
default = min (120* (SCR/PCR), 100%)
bandwidth allocation = PCR (0+1) * %Util
- ABR, ABRFST, ATFST:
default = 100%
bandwidth allocation = MCR * %Util
CBS
The Compliant Burst Size (CBS.) Also known as
Maximum Burst Size (MBS.) The following
configurations apply:
• Units: cells
• Applicable connections types:
- VBR, ATFR
- ABRSTD, ABRFST, ATFST: VSVD = enable
(1)
• Default: 1000
• Range:
- BXM: 1-5000000
- ASI: 1-24000
IBS
The Initial Burst Size (IBS.) The following
configurations apply:
• Units: cells
• Applicable connection types: ATFR (1-107
cells), ATFST
• Default: 1
CCDV
The Compliant Cell Delay Variation (CCDV.) Also
known as CDVT (0+1,) Cell Delay Variation
