A Future Internet Where Cisco Is Meaningless

Martin Casado once worked with a U.S. intelligence agency. He won???t name the agency, but he says he worked with what he believed to be the most secure computer networks ever built. The trouble, he says, was that building these networks was next to impossible, and if you ever wanted to change them, your problems started all over again.

???What was really shocking to me was that, at the time, market forces had totally failed to create networking equipment that the government could use. The government, which has incredibly deep pockets, couldn???t go out and buy what it wanted,??? Casado says. ???It was extremely difficult to make these networks secure, and once you did, you had a really horrible management nightmare on your hands. Moving just one comptuer, for example, meant you had to make eight different configuration changes. You couldn???t move anything ??? you couldn???t touch anything ??? unless you put a tremendous number of people to work.???

Once you bought a piece of networking hardware, says Shenker, you didn???t really have the freedom to re-program it. ???Stuff had to be coded directly into the switch or the router. You would buy a router from Cisco and it would come with whatever protocols it supported and that???s what you ran.???

An interesting article about a company trying to take the “smarts” out of the network hardware and put them in the software.
