The history of the Janet Network
The Janet Network has gone through a huge transformation since it went live on 1 April 1984.
1984 - JANET launches
JANET connects the UK's universities and research councils. At the time, it's the fastest computer network in the world using X.25 with a 48Kbit/s core and 9.6Kbit/s to sites.
JANET backbone upgraded to 256Kbits/s.
Native IP links added to JANET.
SuperJANET ATM network expands to 14 sites.
JANET CERT created.
JANET starts to serve further education colleges.
X.25 is turned off.
SuperJANET III begins service.
SuperJANET 4 begins service at 2.5Gbps.
SuperJANET 4 backbone upgraded to 10Gbps.
Backbone becomes native IPv4/IPv6 dual-stack.
Wide-scale launch of LIN (location independent networking), eduroam’s precursor.
SuperJANET 5 begins service.
JANET Lightpath service launched.
Aurora begins operation.
Tests of 100Gbps on JANET core.
More investment lead to JANET reaching speeds of 100Gbit/s.
Janet6 launches - one of the the world's most advanced computer networks at the time.
eduroam, a roaming service for education users, reaches 95% of universities and is working on 500,000 devices.
Govroam service launches.
400Gbit/s optical technology deployed on Janet backbone.
First 100G member connection.
Janet access programme is launched.
