Agreed. While I'd personally hope that one would up-level the current
topologies to routing by the AS number alone, it doesn't seem to be
the case now, by far (this goes back to the evolution vs revolution
argument). But as you say, this makes only the fact more convincing
that scalability benefits w/ AS-level abstraction may not be
2) your comment #2:
i'm not sure what you mean. do you mean this other 'real'
topology from the previous point? we simply point out that
for the *real AS-level* topology, the routing table size
of the TZ scheme is ~50 entries of ~log(n) bits each, which
means that the average DFZ routing table size is below 100
bytes per node (that's why this type of routing is called
Either would be interesting. If the size of table is something like
50 entries, it should be something folks could examine (much better
than the current topology of 10,000+ entries..) and understand better.
I for one certainly would be interested in seeing what it would look
like (also in comparison with the current routing table).
