Um, something like "a metric shitload". :-) The overall FTTH experiment is basically posing the question "what could we use networks for if we took away the capacity limits?". > What is the layer-3 architecture for the CCZ?

Traffic between homes is taken care of without going further. There is a 1Gbps link out of the switch to the ISP. We mirror the port that connects the switch to he outside world. So, we have no visibility of traffic that stays within the CCZ. > Have you considered isolating the data samples which are from CCZ and > to CCZ, and then tried to predict which flows might involved 802.11b > or g final hops? We have not done that. allman ----------ma736-1 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (Darwin) iEYEARECAAYFAlDvAuAACgkQWyrrWs4yIs5YPQCfUGX8iWe/CnS6MDPSwL4SI2wP 4LUAn3T6mbOfirW+BNxsBCoqvNNBtXPG =Shog -----END PGP SIGNATURE----- ----------ma736-1--
