Bandwidth Policies
Bandwidth policies are bandwidth limitations defined for any set of frames, specifying the
guaranteed bandwidth rates. A bandwidth policy is often based on a rate structure whereby a
Web host or co-location provider could charge a customer for bandwidth utilization. There are
three rates that are configured: a Committed Information Rate (CIR)/Reserved Limit, a Soft
Limit, and a Hard Limit, as described below.
A queue depth is also associated with a policy. A queue depth is the size of the queue that holds
the data. It can be adjusted to accommodate delay-sensitive traffic (such as audio) versus drop-
sensitive traffic (such as FTP).
