The invention discloses a method and apparatus for assigning link "distance" metrics that result in near optimal routing for a network formed of nodes (routers) and links, where each link has a capacity associated with it and where, source-destination flows are given. The routing optimality is measured with respect to some objective function (e.g. average network delay).

Why it's free to use
- Filed June 2, 1994 and granted August 25, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 2, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 2, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
