Networking HistoryNetworking History
Started with 56Kbps lines for the institutes
Collaborated with CANARIE as a test-bed application for the new CA*net II (OC3 ATM lines @ 155Mbps), with Nova Scotia being the first site in the world connected to a national advanced network
![Page 5: The Canadian Bioinformatics Resources – An Overview](https://reader030.vdocument.in/reader030/viewer/2022033018/568160e8550346895dd01cd5/html5/thumbnails/5.jpg)

Networking PresentNetworking Present
In 1998 CANARIE was mandated to create the first national optical Internet network
CA*net 3 uses wavelength multiplexing over fiber to each province’s gigabit point of presence (GigaPoP) Cisco 12008 router
Nova Scotia was the first province connected to CA*net 3, and our CBR servers now run Gigabit Ethernet

Networking FutureNetworking Future
By the end of 2000 all CBR servers should be on the gigabit backbone
Currently CA*net 3 runs two OC48 (2.5Gbps) wave lengths, preparing to increase to eight OC192s (total 80Gbps)

Who uses it?Who uses it? Internal NRC users and their industrial
collaborators use CBR-I terminal access. Members of not-for-profit, research
organizations use CBR-II. Basic Web access is free, terminal and SeqWeb access come with the $195 registration.
