I believe the work is important to help quantify requirements both on
the PE/P side of the problem and the CE side. Understanding how much
cache is required on a CE device with standard customer loads will
help sizing the memory/cache/speed of CE devices.

The same should be applied to the PE/P devices... how much more
RAM/SRAM/TCAM/... is required for large provider boxes?
