OK, I think I know a lot. In fact, I know I know a lot, but every once in a while something comes up behind me and hits me in the back of the head and I am surprised. In this case, I am talking about an article about "stupid networks" by David Isenberg.
This may sound silly, but the Internet is a stupid network. The old telephone network (well, the network that we still use for voice calls, or at least most of us do) is an "Intelligent Network". Follow me so far? The whole point of this discussion is that the Internet takes the control of routing, the destination and the transmission of data away from the network and puts it in the hand of the user or the "client" as computer people put it.
Think of the Internet as a system of highways with cars on it. Drivers decide when and where to enter, where to go and there to get off. Think of the old network at a railroad, with the trains routed by the network from start to end. Railroads are intelligent networks, highways stupid networks.
Well, enough of that analogy. Read the article linked to above if you want his take on this. It is from 1997, over 10 year ago. This came up when reading an article on the Economist about Internet neutrality. What goes around comes around... or something like that.
