Re: Agenda for next NANOG
Randy, There is a cluster of closely-related variants on the issue you raise:  to what extent does a given exchange point (NAP/MAE/etc) constrain the performance that a user sees (in what a user thinks of as end- to-end). For example, an FTP could flow at 800 kb/s for a given pair of users, except that MAE-north is congested, so the FTP can only flow at 400 kb/s.  to what extent does a given exchange point constrain the performance that a provider sees (in what a provider thinks of as end-to-end). For example, a given pair of backbones could sustain 20 Mb/s over a private interconnect with acceptable packet loss, but can only sustain 10 Mb/s over the Altoona NAP.
