Sad but true, we have had to turn off signups outside the US because of 
that very problem. Yes, I am sure we lose some sales, but in general it is 
not worth the fraud costs.

Have you thought about Infiniband? Dual 10 gig cards cost about $50 and 24 
port switches about $1200 on ebay. Infiniband has just a fraction of the 
latency of ethernet (even 10 get eth). You get the lowest latency if your 
application supports Infiniband, but if not you can run IP over IB.

can't get additional space on the server itself so I am looking for

be best for Gbps speeds .


I have done this two ways in the past, first is the simple way, LSI raid

to use Gluster, over a large number of hosts with infiniband connecting

Hello Group,

I was wondering if anyone could share their experience with any route 
optimization approaches, methodologies or platforms, either open source or 
commercial (Internap FCP), that can actively adjust BGP parameters based on 
latency and number of layer 3 hops to a network rather than AS hops.  We have 
upstreams all over the country and we would like to automate optimization to 
take the best egress path.


We were using Internap, but ended up writing our own so that we could look 
at larger number of speakers. The technology is not that complicated, you 
basically take netflow data and send it to a host that has tunnels over 
each one of your BGP peers that you care about. It then uses a combination 
of traceroute and ping to collect its data that is then injected back to 
the router over BGP.

Once you've got the ethernet -> interface problem addressed, you need to
examine bottlenecks in interface->bus and particularly bus->disk.


One good open source solution on the disk side is Gluster with 10 gig 
infiniband on the back end. Gluster allows you to build a distributed 
storage over many servers. You can find 10 gig infiniband cards on ebay 
for around $50 and a good 24 port topspin/cisco switch will cost you about 
$1K.

The reporting is not bad and it does an ok job. We ended up building our

believe the overall idea can provide a lot of value, it just was not the 
best solution for our needs.
