Tolerant Networks was founded in April 2010 by Stephen Farrell and Kerry Hartnett. The company was spun out of an EU FP7 funded project called N4C in which we used Delay Tolerant Networking (DTN) to enable Internet-like communications in very remote communities. We have successfully completed a range of projects in the area of DTN deployment, educational DTN projects and DTN usage for the European Space Agency.

Dr. Stephen Farrell is a research fellow in the Distributed Systems Group of the School of Computer Science and Statistics at Trinity College Dublin, (academic home page) where he teaches and researches on security and delay/disruption-tolerant networking (DTN), and in 2006 co-authored the first book on the latter topic. Stephen has been involved in Internet standards for more than a decade - currently (Feb 2017) he is just finishing up six years as IETF security area director. Prior to returning to academia in 2002, Stephen had 15 years experience in industry, working for Siemens and Baltimore Technologies amongst others.

With over 20 years experience in IT Kerry Hartnett is an experienced and versatile senior IT professional. Kerry worked with Intel for 15 years in all aspects of IT. Commercially aware and results-orientated with a wide range of technical abilities, Kerry's planning and organisational skills have enabled him to repeatedly deliver complex integration projects to schedule. Kerry has a BSc. in Information Systems and is currently working on contract as a research engineer on the N4C project. Kerry's current focus is on new technology deployment in networks and research.
