Minor nitpick--an IXP never 'produces' bandwidth;
it facilitates movement of data between entities,
but the IXP itself shouldn't be producing bandwidth.
It's the allocation of ports and cross connects from
members into the IXP that produce the bandwidth,
and that would be the case even if the IXP were
removed from the picture and the ports were
cross-connected back-to-back.

(I suppose if an IXP switch fabric were compromised,
someone could use it to generate traffic that did not
originate from any member port, but that would be
a very unusual circumstance indeed...)

Thanks!
