Here is a qoute from the above document:

"Committed Information Rates (CIRs) increase network control by providing a mechanism for prioritizing end user data on a per-PVC basis across a given UNI. A CIR allows a sustained throughput at a chosen rate."


By contrast, a burst rate is a maximum unsustainable rate.
