Yesterday, after 6 years, was my final day as chair of REANNZ (Research & Education Advanced Network New Zealand Limited). REANNZ has been a fantastic business to be part of. It is a highly specialised national and international telecommunications company with a very particular technological advantage. In layman's terms, REANNZ moves heaps and heaps of data very, very fast. We're talking truly huge data flows - astronomically large files (literally). Normal telcos are optimised to move lots of small packets of data. REANNZ (like its partner R&E networks around the world) moves data in a different way. A normal network might need to re-transmit 1 out of every 100 or 1000 data packets. REANNZ has a packet loss rate of 1 in hundreds of millions. That has huge performance implications for large discrete data flows over long distances. What REANNZ moves in an hour can take days or even months on a conventional network. That means researchers...
