[LINK] Google's Expresso routing the Internet

[Jim Birch]

"Let’s start with a little history. A problem that we were facing was that
standard, existing routing protocols, primarily Border Gateway Protocol or
BGP, which is used for all pairing among different networks, is focused on
individual boxes, and essentially what this means is that they have to take
a very local view about connectivity. As soon as they can find a path
between a source and a destination, two computers that want to talk to each
other across the network, then BGP is happy. It doesn’t try to find the
*best* path, and it doesn’t try to do dynamic optimisation."
