Hi All,
Sorry if this is a repeat topic. I've done a fair bit of trawling
but can't
find anything concrete to base decisions on.
I'm hoping someone can offer some advice on suitable hardware and
kernel
tweaks for using Linux as a router running bgpd via Quagga. We do
this at
the moment and our box manages under the 100Mbps level very
effectively.
Over the next year however we expect to push about 250Mbps outbound
traffic
with very little inbound (50Mbps simultaneously) and I'm seeing
differing
suggestions of what to do in order to move up to the 1Gbps level.
It seems even a dual core box with expensive NICs and some kernel
tweaks
will accomplish this but we can't afford to get the hardware purchases
wrong. We'd be looking to buy one live and one standby box within
the next
month or so. They will only run Quagga primarily with 'tc' for
shaping.
We're in the UK if it makes any difference.
Any help massively appreciated, ideally from those doing the same in
production environments.
Give Click a try - it is an alternative forwarding plane for Linux,
that ran much faster than regular Linux forwarding a few years ago,
and I imagine would still do so.
The XORP routing suite supports various different FIBs, including Click.
