Matthew Kaufman, is making a bad analogy. The phone network
is completely static routed, there is current VERY high
level of aggregation. There is NO capacity to
reroute connections on the fly. Backup paths
exist, but if you trunk gets cut, your circuit will go out.
The phone network is source routed. The source switch
finds a path to the destination number.
So Justin wants Cisco to redisgn the Internet, and take
out all of the "good" features of connectionless, active
routing networks.
And as someone else remarked, the CA PUC will for its nexct trick
make PI equal to 3.
And I'll bet anyone on this list, a nice lunch, that
the number protablity will be based on phone companies selling each other
"minutes" and settling out the money.
Of course Bob Metcalf, might just like for the Internet
to be run this way.
