Hosted System Bandwidth And Cac Calculations - Lucent Technologies Stinger Compact Remote Getting Started Manual

Hosted system bandwidth and CAC calculations

For a general description of CAC and how the system uses guaranteed bandwidth
values for CAC purposes, see the Stinger ATM Configuration Guide. For details about
each CAC setting, see the Stinger Reference.
Following are the LIM and trunk CAC parameters, shown with default settings:
[in SLOT-STATIC-CONFIG/{ shelf-M slot-N 0 }]
allow-guaranteed-up-stream-bandwidth = 42500
port-cac-enable = no
port-over-subscription = 10
slot-cac-enable = yes
slot-over-subscription = 10
[in HIGH-SPEED-SLOT-STATIC-CONFIG/{ shelf-1 trunk-N 1 }:trunk-cac-config[1]]
enable = yes
over-subscription = 10
Parameter
allow-guaranteed-up-
stream-bandwidth
port-cac-enable
port-over-subscription
slot-cac-enable
slot-over-subscription
enable
over-subscription
With the default CAC configuration, for an RLIM-to-trunk PVC connection request,
the system performs bandwidth calculations in the sequence shown in Figure 5-3:
1 RLIM slot bandwidth
2 Trunk port bandwidth
3 OLIM slot bandwidth

Setting
Guaranteed upstream bandwidth. The system uses this
value for CAC purposes. For information about
allocating LIM bandwidth, see the Stinger ATM
Configuration Guide.
Enable/disable CAC on the LIM's ports.
Factor (from 0 to 10,240) by which a LIM port allows
oversubscription to the port PHY bandwidth. A value of
zero disables port CAC.
Enable/disable CAC on the LIM slot. Slot-level CAC is
enabled by default with this new setting.
Factor (from 0 to 10,240) by which a LIM slot allows
oversubscription to its provisioned guaranteed
upstream bandwidth. A value of zero disables slot CAC.
Enable/disable CAC on the trunk port. Trunk port CAC
is enabled by default.
Factor (from 0 to 10,240) by which a trunk port allows
oversubscription to its PHY bandwidth.
