Of course it isn't. You can *approach* 10gb/sec with multiple cores and minimum packet sizes, granted. > You don't need to handle more packets than you can possibly receive over your > interfaces. Yes, you do, because forwarding 64-byte packets at 'line-rate', whilst very important, isn't the only metric. I know all about the forwarding capabilities of modern general-purpose CPUs, ring-buffers, et. al. I know what is possible, and what isn't possible. And please, no more from the Vyatta crowd, et. al. - they're like the s/Flow shouters, only more so. ----------------------------------------------------------------------- Roland Dobbins <rdobb...@arbor.net> // <http://www.arbornetworks.com> Luck is the residue of opportunity and design. -- John Milton
