Flow control of packet based traffic by window is known.

The description also shows how the flow control mechanism can be constrained to a maximum rate. The configured numbers will assure that the connection can always run at a minimum rate but not more than a maximum rate.

Why it's free to use
- Filed September 30, 1998 and granted July 8, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 30, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 30, 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.
