The internet, as we know it today, was shaped by a relatively small number of engineers who saw past the limits of a small network and imagined something far grater. Dr Robert E Kahn was one of those people. Along with Vinton Cerf, Kahn was the co-invetor of TCP/IP - the network protocol that underpins the internet. Add the physical layer, ethernet, that Bob Metcalfe created and Tim Berners-Lee's world wide web, and much of what we rely on today came from the work of just a few pioneers. I had the opportunity to hear Dr Kahn speak on what he sees as the next big thing when it comes to the digital world.
