Changes to NTP 241-9501-301 Vector Management Interface User
Guide
This section provides changes to the NTP 241-9501-301, Vector Management
Interface User Guide, chapter 4, "Connection admission control for SVCs",
section, "Aggregate maximum bandwidth for all switched virtual circuits",
page 82, must be read as follows:
For each Quality of Service (QoS) setting, bandwidth added to the aggregate
SVC maximum bandwidth is as follows:
•
•
•
•
•
•
for a CBR SVC connection, its peak cell rate (PCR) is counted in this
parameter
for a VBR SVC connection, its "equivalent bandwidth" is counted in this
parameter
for a UBR SVC connection, its representative bandwidth is counted in this
parameter
this aggregate bandwidth must be larger than the maximum bandwidth
parameter for each SVC
the aggregate SVC maximum bandwidth can be provisioned a different
value for each of the users-to-network and network-to-user directions
the pre-configured maximum aggregate bandwidth for all the SVCs is
compared against:
equivalent
bandwidth
admitted (in case of a UBR connection, it will
equal
the
+
bandwidth)
SVC connections (in case of a UBR connection, each
SVC connection will consume 3 cells per second)
number of active UBR connections on the fabric
UBR representative bandwidth
If the maximum pre-configured aggregate bandwidth is reached or
exceeded no additional SVCs can be admitted.
