Open the CIPO recordAbstract From the Canadian patent
For assigning bandwidth in a constrained topology ethernet network there is presented a function that creates and manages a ledger of bandwidth requests over the ethernet network. The function a bandwidth manager, tracks the total bandwidth of each link in the network and the bandwidth that has been reserved on each link. When traffic is granted reserved bandwidth the bandwidth manager notes this allocation in the ledger. The header of the traffic packets indicates that the traffic is of highest priority when the traffic has been given reserved bandwidth. In this manner the bandwidth manager can track and limit the amount of high priority traffic on the network.

Why it's free to use
- Filed November 29, 2001 and granted January 11, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 29, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 29, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
