100Gbit Deployment
There is no source cited, and based on news articles, this happened in 2009/2010, not April 2011. "In April 2011 Verizon helped Janet upgrade 4 central locations to run at 100Gbit/s - the first national research and education network in the world to do so." What about Internet2? I see on their wiki page that they had 100gbit in the backbone as early as 2006. —Preceding unsigned comment added by 68.36.29.67 (talk) 00:12, 19 April 2011 (UTC)
 * There were trials of the 100Gb/s technology in 2009/2010, and it was deployed on the production network in 2011. I believe that Internet2's 100Gb/s links were bundled 10Gb/s circuits, these refer to single 100Gb circuits. Jamesd (talk) 11:19, 22 June 2011 (UTC)

Backwards domain names
So what I remember about Janet, circa 1993, is the backwards domainnames you had to use: uk.co.bbc, uk.co.archive. Perhaps it was just the UK ones. But does anyone else remember this. If so is it worth a note on this page? Preferably with a reason - which escapes me - to why this was. --Ooblick 21:41, 28 February 2006 (UTC)


 * It was so mandated by Coloured Book. I've added a note to this page. The Wednesday Island 17:34, 13 June 2006 (UTC)


 * there called UNC path names, they were used on Novell Networks


 * No mention of the Rape of JANET then ? Or isnt there anyone here remembers it, the most brilliant  hack of its day? 82.21.207.51 (talk) 21:13, 24 May 2011 (UTC)
 * I think the reverse-ordered domain names were a legacy of the JANET nomenclature. In 1986 I tried sending an email from a UK University to an Australian one and soon found myself caught in an exchange between sysadmins. The Australians had followed the US system (ARPANET?) and complained about “bass-ackward UK system.” The UK sysadmin countered that JANET had “always” used this system.
 * Emails between Australia and the Uk must have been pretty routine at the time, so I was staggered that my attempt caused so much annoyed (electronic) correspondence. I should have paid for a stamp. 124.168.248.86 (talk) 23:09, 23 September 2023 (UTC)

Relation to Alvey would be useful
The relation to Alvey especially when intellectual property was concern needs to be detailed. -- enm 23:30 18 Aug 2006 (UTC)
 * The only reliable source I can find about relationships between JNT and Alvey are with regards to funding of the initial US/UK/JANET/NSFnet link, and a contribution to the JANET Rainbow Books Jamesd (talk) 12:36, 22 June 2011 (UTC)

Gigabit Ethernet
When did the Janet backbone abandon ATM and swich to Gigabit Ethernet. -- Petri Krohn 03:02, 6 March 2007 (UTC)
 * ATM disappeared around the time of SJ4, before my time though I'm afraid. Jamesd (talk) 12:26, 22 June 2011 (UTC)

Content fork
Any reason for having Janet and Janet(UK), shouldn't they be merged? Khu kri  17:19, 12 March 2008 (UTC)
 * The former is a network, the latter is the organisation running it.--Jotel (talk) 17:22, 12 March 2008 (UTC)

What helped make Janet successful?
This section looks like original research. Please provide reliable sources, see WP:NOR and WP:SOURCES —Preceding unsigned comment added by 85.214.22.8 (talk) 17:30, 15 March 2008 (UTC)

Links
Is "Socialism" really a valid link from this page? It is a government-funded entity, but to link to "Socialism" seems rather political... —Preceding unsigned comment added by 90.203.226.6 (talk) 00:14, 16 November 2008 (UTC)


 * Agreed - I've removed the link.  [ジャム] [talk] 00:32, 16 November 2008 (UTC)

Was Janet a backronym?
I have a memory of Janet being named after a secretary at, I think, the JNT and it was reverse engineered to be the Joint Academic Network. Apepper (talk) 19:20, 7 May 2009 (UTC)
 * I've seen various "sources" that say it was the name of the founder's secretary, yes. I don't know if there are any reliable sources around to back this up though.  [ジャム] [ t  -  c  ] 19:32, 7 May 2009 (UTC)
 * The official line is that it's from the Joint Academic NETwork, and that it was merely an amusing coincidence that the JNT secretary at the time was Janet. See http://www.ja.net/documents/publications/janet-history/janet-the-first-25-years.pdf page 75. Jamesd (talk) 12:32, 22 June 2011 (UTC)

On the other hand, Roland Rosner stated in his retirement speech that it was actually down to the secretary's name. Maybe someone could ask him? — Preceding unsigned comment added by 194.169.1.75 (talk) 13:19, 24 October 2019 (UTC)

Did it really start that late
I started using an X25 network in 1981-2 and I am sure it was Janet. I was at Reading uni doing a PhD and there was a large cube of a computer a GEC4040, if I remember correctly, in the physics dept that was a node for Janet. I had a 2.4kbaud link to that machine from my office. I think that Janet was available in 1981 and certainly 1982. I used to link up to a DEC10 in Glasgow Strathclyde university using a program called ESP in the ABACUS dept.

 * Possibly you're remembering SERCNet Jamesd (talk) 12:29, 22 June 2011 (UTC)

The Rape of Janet
I remember reading an article many years ago about an attack on JANET, being the first successful modern hack, which became know as The Rape of janet. This was about the same time or slightly before someone hacked into Prince Charles CEEFAX accountin the 90's, does anyoen have further information ?

84.234.16.202 (talk) 12:26, 15 February 2010 (UTC)


 * Cornwall/Sommer's publication "The Hackers Handbook" 1994 edition covers the Rape of JANET on p109-110. He appears to have uploaded that edition to his site at
 * 81.132.149.194 (talk) 08:12, 30 April 2021 (UTC)
 * And there is a BBC article on the hack of the Duke of Edinburgh's Prestel account. Whizz40 (talk) 14:55, 14 September 2022 (UTC)

Mid-80s backbone speed
We'll need a source for the "In the mid-80s the backbone was upgraded to 2 Mbit/s" content, as Janet's own https://www.jisc.ac.uk/janet/history page says that JANET backbone upgraded to 256Kbits/s in 1986 - scruss (talk) 14:38, 14 September 2022 (UTC)
 * Best corrected then. Whizz40 (talk) 14:53, 14 September 2022 (UTC)
