We used it in a previous life, in the same way we used Cisco's QPPB to
track utilization data associated with specific routes. That was during
a time where there was a large delta between national and international
traffic.

When CDN's began to flood local markets and became part of the national
traffic, it made little sense for that use-case. But I'm sure there are
others who are using this for other purposes.

I've not seen any performance or scaling issues, across the older DPC
and newer MPC line cards.

Mark.
