Patent ID: 7570588

Claim:
In a telecommunication network having a plurality of interconnected switches, a method of adjusting a committed information rate of traffic for a virtual circuit comprising the steps of: a) obtaining statistical data for the plurality of interconnected switches, wherein the statistical data relates to respective amounts of data that pass through the switches; b) identifying for each of the plurality of interconnected switches, virtual circuits that make excessive use of the network; c) adjusting the committed information rate of traffic to form a modified committed information rate of traffic, wherein a probability model is used to determine the modified committed information rate of traffic, wherein the probability model includes a discrete probability model; and d) computing a value for m, which represents a number of samples exceeding a first threshold value R 1 ; and e) if m n ⁢ > _ ⁢ R 2 , where n represent a number of samples, then for each sample, S i , having red traffic over the threshold R 1 computing a revised capacity C i , such that an estimated amount of red traffic will be below a first target threshold, T 1 .
