Andrew, The Princeton SOSP paper, "Building a Robust software-based router using NPs" has some measurements for forwarding rate from the IXP to the host PC. But this system is not linux based, if that is what you are looking for. There was some discussion regarding this on this mailing list sometime earlier which you can get in the archives. Also, I think Georgia Tech group had presented some numbers at the IXA 2002 workshop on moving packets between the IXP and host, I think. -- abhijeet On Tue, 28 Jan 2003, Andrew Putra Jauri wrote:
Hi,
I was wondering if anyone has looked into passing the packet from ixp board from and to the host linux kernel through the pci bridge? I know it seems ridiculous since that will waste all the resources we have in the ixp board, anyway I'm just curious.
