We are looking at getting an additional transit connection. In the past, we have used fixedorbit.com and the like and "guesstimated" our best transit choices. (Other factors came into play as well, of course, such as price...) Anyway, does anyone have a suggestion for determine our next best transit? Essentially, I am looking for techniques of: 1. Gathering our current traffic patterns and subtotalling source/destination IP by ASN. 2. Gathering our BGP views into a useful form for analysis. 3. Using #1 and #2 to analyze which new AS would make the most sense to connect to for transit. The goal would be for the new transit to reduce the number of AS we must transit given our customer's actual usage. I could probably hack something together on my own, but before I go reinventing the wheel, I'm interested in getting feedback from the list. We use all cisco's in our backbone, so a cisco-centric solution is fine. (Note to sales-droids on the list: this is not an invite to send me sales messages. Please.) Thanks! John

There's a number of tools available (search for 'netflow' on freshmeat.net) to collect flow data and produce aggregated reports pr source/dest AS. Your problem is with #2 and #3 above. I don't know any open-source solution that will combine the data from #1 with the AS-PATH from #2. What you want to look for in #3 is the AS'es of your potential transit providers in the AS-PATHs in the final report.

I've done exactly this kind of reporting in the past as an ISP engineer to use as input to peering discussions, but don't have any of the old code available. There's a relatively new tool called Stager (http://software.uninett.no/stager/index.php?page=stager) designed for various forms of reporting on network traffic data, including netflow. It is supposed to be relatively easy to customise and may provide the hooks you need to add the "AS to AS-PATH" relation. //Per

Subject: Re: Choosing new transit: software help?
A remarkably large list of netflow tools is maintained at: http://www.switch.ch/tf-tant/floma/software.html It distinguishes between free and commercial software.
