Patent ID: 7613166

Claim:
A method for routing circuits through a telecommunications network using dynamic self-adjusting weights assigned to links in the network, each said link having an administrative weight, the telecommunications network including a plurality of telecommunications switches, the method comprising (a) an individual one of said telecommunications switches calculating respective new administrative weights for the links, (b) said individual one of said telecommunications switches calculating a route for an individual one of the circuits using the new administrative weights, (c) wherein a new administrative weight for a link is given by new administrative weight=administrative weight+ Y *administrative weight, where Y = U − T if U > T, Y = 0 if U < T, U is the fraction of the link's bandwidth that is in use, and T is a number between 0 and 1, and (d) said individual one of said telecommunications switches communicating information about the calculated route to at least one other one of said telecommunications switches along the calculated route.
