Vint Cerf on the Future of the Net
johnd writes "The internet is set to become the basis for just about every form of communication, according to net pioneer Vint Cerf, and he should know what he is talking about. Not terribly in depth, but an interesting read all the same."
We should all ask ourselves: The internet was not designed for this, wouldn't it be better to use something that was?
The Internet was not designed, period.
The Internet grew into what it is now from a large variety of smaller networks. The protocols that make the Internet as we know it work were designed, to be sure, but most of them weren't even designed together. DNS, for example, is an essential factor in today's Internet, but it was designed independant of TCP/IP. The same can be said of SMTP, FTP, HTTP, etc. These things came about to fill needs as they arose.
And the Internet will continue to grow and evolve. Even IP, the net's fundamental building block, will change as IPv6 is implemented.
The Internet is a fantastic example of the power of bottom-up design. Implicit in your comment is the notion that we'd be better off usign a top-down design, where we sit around and think up all the things we want the net to do, and then try to design a big system that has facilities for all those different things. I think that if we did that, we'd either fail miserably, or we'd end up with something that looks very much like today's Internet.
