Abstract
A network element is deployed in a network of interconnected elements. The network element includes a shared buffer multiplexer connected to a link, a set of regulators connected to the shared buffer mulitplexer, and an admission control unit communicatively coupled to the set of regulators and the shared buffer multiplexer. Each of the set of regulators has an input traffic flow. Each traffic flow has a varying flow rate. In order to control admission of the traffic flow to the link in the network element, the admission control unit evaluates the traffic flowing into each regulator. For each traffic flow, the admission control unit receives an envelope of the flow input to the regulator. The admission control unit maximizes the entropy of a distribution of the rate of flow over all time scales. The admission control unit determines the maximum-entropy distribution for the flow using information derived from the traffic envelope, including bounds of the mean rate, the minimum rate, and the maximum rate. The admission control unit approximates the rate variance of the maximum-entropy distribution for a given maximum rate. The admission control unit makes an admission control decisio…
