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.
From different perspectives, each of these notions of end-to-end has
meaning. Would you want to consider one or the other or both in the
panel?
