DESCRIPTION
"This attribute is a vector of five traffic parameters whose meanings
are defined by the trafficDescType attribute. The values of peak cell
rate (PCR), sustained cell rate (SCR) and requested shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MBS and CDVT are used for connection admission control
(CAC). The value of CDVT is only used for connections where the
atmServiceCategory is constantBitRate. For all other values of
atmServiceCategory, CDVT is ignored. The values of PCR, SCR
and requested shaping rate are used to determine the actual shaping
rate where traffic shaping is enabled.
When trafficDescType is 3, parameter 1 represents the PCR for CLP
equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When trafficDescType is 6, parameter 1 represents the PCR for CLP
equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP
equal to 0 and 1 traffic; parameter 3 represents the MBS for CLP
equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2, and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5 must either be zero (unused) or greater than or equal to parameter
2.
When trafficDescType is 7, parameter 1 represents the PCR for CLP
equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP
equal to 0 with cell discard; parameter 3 represents the MBS for
CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2, and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5 must either be zero (unused) or greater than or equal to parameter
2.
When trafficDescType is 8, parameter 1 represents the PCR for CLP
equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP
equal to 0 traffic with cell tagging; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2, and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5 must either be zero (unused) or greater than or equal to parameter
2.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate.
For trafficDescType 3 the traffic is shaped at the next rate less than
the PCR.
For trafficDescType 6, 7, and 8, the traffic is shaped at the highest
available rate which is between PCR and SCR. However, if there is
no available shaping rate between PCR and SCR, traffic is shaped at
the next rate above the PCR."
