For approximately eight years starting in the mid-1980s, a seminar series called the “Australian Teletraffic Research Seminar” was run on an annual basis. In 1993 the last of those seminars was conducted at RMIT University, Melbourne Australia and at that point, Telstra management felt that there were three seminars in Australia that attracted similar people and that they would only support a combined conference which brought together the three seminars titled “Australian Teletraffic Engineering Research Seminar”, “Australian Multi-media Communications, Applications & Technology Workshop” and “Australian Broadband Switching & Services Symposium”. Each of these had their own separate seminar series that had been supported by Telstra and were run in Australia.
From this amalgamation, ATNAC was born and the first one was held in Melbourne in 1994 with General Chair Paul Kirton from Telecom Research Labs. Several ATNAC conferences followed after that until it was delivered as a joint conference with the International Switching Symposium in Sydney in 1996.
The next ATNAC conference was held in 2003 in conjunction with the re-formation of the Australian Telecommunications CRC. The Australian Telecommunications CRC CEO, Leith Campbell, suggested that ATNAC be revived as a flagship of Telecommunications research in Australia. This new revitalised series began in 2003 and has continued uninterrupted ever since.
In 2007, a minor name change occurred but did not alter the name “ATNAC”. The first ‘A’ in ATNAC was originally “Australian” but was changed to “Australasian” and the first ATNAC held outside Australia was held in Christchurch New Zealand in 2007. The idea being to host one in every three conferences in New Zealand for the foreseeable future.
ATNAC 2013 was held in Christchurch, New Zealand with General Co-Chairs Dr Mark A Gregory and Prof Richard Harris. It was held in conjunction with the 22nd ITC Specialist Seminar on Energy Efficient and Green Networking, with General Co-Chairs Prof. Krys Pawlikowski and Prof. Phuoc Tran-Gia.
ATNAC 2014 was held in conjunction with the Engineers Australia Convention 2014 in Melbourne, Australia with General Chair Dr Mark A Gregory between 26-28 November 2014.
In 2015 the name to be changed to "International" in response to a funding requirement in some countries that conferences include "International" in the title. Whilst the change in the name meant that the abbreviation "ATNAC" has become "ITNAC" this was considered to be a small change if it meant the conference would continue to attract high quality papers from around the world.
ITNAC 2015 was held at University of New South Wales in Sydney, Australia with General Co-Chairs Dr Mark A Gregory and Associate Professor Vijay Sivaraman between 18-20 November 2015.
