Hi, Stuart.

] So you believe that the edges of the net are smaller, bandwidth-wise,
] than the core?

This was certainly the case in my previous life at a large hosting
provider.  We had GigE LANs, used providers with OC192 backbones,
but had only OC3 to OC12 links to our providers.  Like most edge
networks, we had CIRs on those uplinks that were considerably
lower than the pipe size.  A full OC12 turned out, at the time, to
be darn expensive.  :)

Our choke points were always our peering or transit links.  This
was the case for our (large) enterprise customers as well.

Thanks,
Rob.
