Van Jacobson gave a Google Tech Talk on some of his ideas of how a modern, global network could work more effectively, and with more trust in the data which changes many hands on its journey to its final destination. Watch the talk on Google's site The man is very smart and his ideas are fascinating. He has the experience and knowledge to see the big picture and what can be done to solve some of the new problems we have. He starts with the beginning of the phone networks and then goes on to briefly explain the origins of the ARPAnet and its evolution into the Internet we use today. He explains the problems that were faced while using the phone networks for data, and how they were solved by realizing that a new problem had risen and needed a new, different solution. He then goes to explain how the Internet has changed significantly from the time it started off in research centres, schools, and government offices into what it is today (lots of identical bytes being redundantly pushed to many consumers, where broadcast would be more appropriate and efficient).
