Open the CIPO recordAbstract From the Canadian patent
A system determines that a frame relay connection exists between an interface on a first interface device and an interface on a second interface device for , example by comparing addresses resident in routing tables of the interface devices. The system then queries each of the first and second interface devices, to determine the amount of traffic that is communicated by each channel of each of the two interfaces. This data is then correlated to determine the relative amount of data by each channel on each of the two interfaces, and the pair of channels having the best correlation are determined to represent an actual connection.

Why it's free to use
- Filed March 18, 1998 and granted December 31, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 18, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 18, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
