Group Bandwidth Limit Policy – Operation
The NSE maintains a collection of all installed group bandwidth policies. The collection is
indexed by the bandwidth policy ID provided by the RADIUS server. The collection can store
as many policy records as the number of licensed subscriber devices. All subscriber devices
sharing the same group bandwidth policy ID belong to the same group. A subscriber device
can participate in only one bandwidth-limiting group at a time.
When a login is performed to an account that returns a bandwidth policy ID that does not yet
exist in the NSE, a new policy record is created and inserted into the aforementioned
collection. The subscriber authorized by the Access-Accept is associated with the newly
installed bandwidth policy ID, and the bandwidth limits returned are invoked.
When the Access-Accept for a subscriber contains a bandwidth policy ID already present on
NSE, the subscriber is associated with the existing group policy. All subscribers that are now
members of the group share the total bandwidth allocated to the policy.
If at some point a login is performed to an account that returns the policy ID for an existing
policy, but also returns bandwidth values different than those currently allocated for that
policy, the policy will be updated with the new values found in the Access-Accept. Thus, the
latest Access-Accept determines the current rates for the entire group.
The lifetime of a group policy record in the collection is determined by the session time of the
authorized (i.e. VALID) subscribers participating in the group. Group policy records are
removed from the collection when the last subscriber device belonging to the group is logged
out of the NSE regardless of the reason (e.g. session timeout, idle timeout, deletion of the
subscriber by an administrator, etc).
The NSE does not support the ability to enforce both per-subscriber and group bandwidth rates
simultaneously for the same subscribers. The RADIUS server must specify either per-
