Well, you'd have to re-design the networking code to support NUMA architectures, with a fairly fine granularity. I'm not sure you'd gain anything except possibly for the forwarding fast path. A cheaper, and probably more useful possibility is hardware assistance for specific operations. E.g. hardware-accelerated packet classification looks interesting. I'd also like to see hardware-assistance for shaping on other media than ATM. - Werner -- _________________________________________________________________________ / Werner Almesberger, ICA, EPFL, CH Werner.Almesberger@xxxxxxx / /_IN_N_032__Tel_+41_21_693_6621__Fax_+41_21_693_6610_____________________/ |
