Abstract
A 'per flow' flow monitor is operatively associated with each ingress port of the switch of the data network, for monitoring the arrival data flow on each flow in defined traffic constraint envelopes containing frames. An eligibility time computation mechanism computes an eligibility time at which arriving frames on each flow will be conformant to the defined traffic envelope to the ingress port given past frame arrivals on that same flow. A holding mechanism holds the arriving frames on each flow until the eligibility time is reached. A release mechanism releases the arriving frames on a flow at the eligibility time. The flow monitor, computation mechanism, holding mechanism, and release mechanism cooperate to provide an 'per flow' traffic shaping function in conformance with delay and delay-jitter bound, frame loss probability, and bandwidth provisioning requirements, thus allowing the switch to enforce the traffic constraint envelope for each flow.
