[e2e] Papers on router performance

[Filipe Abrantes]

Does someone know any papers or practical studies on router (hardware) 
performance limitations - specially about its performance when they have 
to examine certain fields on IP or network header on a per-packet basis.

For instance, what is the maximum output bandwidth when it has to 
examine the TOS field in each incoming packet.

Hope I could make my self clear and
Thanks for your help

Filipe
