Open the CIPO recordAbstract From the Canadian patent
A facility for mapping a plurality of different Virtual Circuit Channels (VCC) into a single VCC is provided for use in a data network. In operation the facility assembles, in turn, data cells each having a data payload and appropriate header identifying a respective VCC into a series of data cells. The series is then segmented into a predetermined number of data payloads and a header identifying a common connection over the network is then appended to each of the payloads. The result is then transported over the data network via the common connection.

Why it's free to use
- Filed July 29, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 29, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 29, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
