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? -chris On Wed, Nov 19, 2008 at 1:45 PM, Eliot Lear <[EMAIL PROTECTED]> wrote: > Dimitri, > > I've done some work in this space, but the best data I know of still is the > work done by Iannone & Bonaventure: > >
