CA*net 2

The second main CANARIE (Canadian Network for the Advancement of Research, Industry and Education) initiative, CA*net 2, soon followed as the replacement Research and Development national backbone network. It was based on the ATM (Asynchronous Transfer Mode) and SONET facilities operated by Canada's Telecommunications carriers. Average speeds were to be 155 Mbps, the fastest and largest national network in the world (at start-up time).

CA*net 2 is connected in each province to Regional Advanced Networks (some provinces have more than one connection to their RAN), via GigaPoPs (Gigabit Point of Presence). A list of Regional Advanced Networks is shown in Table 1.2, based on October 1997 data.

CA*net 2 would connect to the US ``vBNS" (very high-speed Broadband Network Service) and ``Internet 2" initiatives. CA*net 2's European connection was done via the Halifax GigaPoP.

NRC was connected to CA*net 2 via an ONet GigaPoP located in building M-60 of the Ottawa Montreal Road Campus. The Canadian Bioinfomatics Resource (CBR) based in the Institute for Marine Biology in Halifax, was the driving force behind that connection.

CA*net 2 would be replaced by CA*net 3.
