Question about ip accounting

Hello 

I'm in a six months placement at Gitoyen http://www.gitoyen.net/
(a small 
opensource-based LIR)

Gitoyen is a Local Internet Registry. The current routing
solution is 
based on Linux with Quagga running OSPF and BGP. All routers
runs 
Linux from USB flash drives but we think that FreeBSD could
be much better 
with OpenOSPFD and OpenBGPD. My mission at Gitoyen is to be
able to route 
about 2Gbps at 190 kilo packets per second using opensource
softwares...

Can you give me some advices on IP accounting? It must be
lightweight to let 
openbgpd working fluently. If informations could be
retrieved by snmp it 
would be great too.

I found two ways of doing this: using pf or netgraph
(particularly the ports 
ipaccounting_ng) so the questions are: 
- Is there a best way to do this? 
- Wich solution is the "lightest" for a router? 
- Is there a other ways to do IP accounting?  

Thanks for your help,

Regards,

Vincent Mialon

First of all Quagga, OpenOSPFD and OpenBGPD only handles
routing 
information. Packet forwarding is done in the OS. (But if
you have lots of 
routing updates the routing software could matter)
A way to higher performance under linux could be:

Anyone looing at supporting the netfpga card on FreeBSD?
I would love to do that project myself, my time is scarse
right now.

I believe there was some interaction between other XORP
members and the 
NetFPGA people, although I don't know if this resulted in
any outcome.

It's on my "sometime" list..
BTW people ha ve been having trouble getting the expected
throughput 
with those cards in some systems according to teh mailing
lists
so there are some traps for young players in there..
