3. Kernel features for complex network solutions (netgraph, carp, ipfw).

The niche for routers & traffic analysis is still ours. It would be nice to take e.g. pfSense and agree with some vendor (Netgear, D-Link, etc) to put on sale hardware with FreeBSD inside.

What about 10G routing? Here are reports about full-bandwidth 10G routing on modern Intel NICs with Linux (and multi-core server), but I didn't see any such data for FreeBSD, and somebody says, that Intel drivers and network stack is not so good parallel in FreeBSD.

With regards to high speed packet forwarding and routing, check out this work by Luigi Rizzo: http://info.iet.unipi.it/~luigi/netmap/

Yep, I know this work, but it is rather special, not out-of-box (ok, maybe with some changed tunables) routing solution with routing tables, some firewall, etc.

I think we need to refocus on what would give the most benefit. At least as far as I can see:

- port/package management: most users would benefit - improved virtualisation support: a lot of users would benefit - improved driver support: a lot of users would benefit - KMS/GEM for better graphics card support: a lot of users would benefit

Can you honestly say the same about handling line rate packet forwarding for multiple 10G cards?

I suspect I would rank true multipath storage support above 10G routing, for example.
