TRAFFIC SHAPING AND METERING SCHEME FOR OVERSUBSCRIBED AND/OR CASCADED COMMUNICATION DEVICES

摘要

A method for shaping traffic in an oversubscribed environment, supporting multiple queues and classes of service and extending this approach to cascaded devices is disclosed. The invention permits use of oversubscribed line-interface devices without adversely affecting high priority traffic and allowing the use of lo cost networking devices such as network processor units.
