This invention defines a routing method which allows to determine best paths from link weights in situations where these weights are not additive, but the characteristic of a concatenated path is determined mainly by single "bottleneck" links. To be compatible the, metric must be chosen from a specific set of metrics called bottleneck metrics in this description. The new widest-path method has some characteristics in common with the known Dijkstra method for additive weights. Implementations in communication networks are disclosed which lead to new nodes, new networks and new network protocols. The widest-path method however, can solve many other routing, problems not necessarily related to …

Why it's free to use
- Filed December 24, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 24, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 24, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
