Abstract From the Canadian patent

A method for flexible inverse multiplexing for ATM and for link grouping (106) of communication links (103, 104, 105) with different transmission rates and delay. The method of the present invention supports links which use a portion of the link bandwidth for one QoS objective (e.g. low delay) and another portion for another QoS objective (e.g. low cell loss). The method involves servicing each of a number of multiplexed flows (300) with a predetermined number of cells. Cells (309) are assigned to each flow (302 304, 306) during , a number of cycles which make up an ATM frame. The number of cells assigned to each flow during each cycle is dynamically adjusted based upon the …

Why it's free to use

  • Filed February 7, 2000 and granted April 12, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 7, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 7, 2022.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
