Visualizing BGP paths

Mailman List Mirror (Read Only)

I have been working on a project to better illustrate for our manages
the provider path data takes when it flows from one of our customers to
our datacenter. I have tried to use trace routes to illustrate the
number of hops data takes, but when I try to show many sources on one
page, it gets fairly messy quickly. I am also less concerned with the
number of hops, and more concerned with the number of providers.
Does anyone know of a toolset that will take a list of source IP's and a
destination IP and show graphically which as numbers the packets need to
traverse to reach our datacenter? I am thinking of something like this:
http://www.robtex.com/as/as19629.html#graph, but instead of all the
upstreams it would show something like AS16150 -> AS1239 -> AS209 ->
AS19629.

I like BGPlay:

I use BGPLay for showing our connected status, but it doesn't let me put in a source IP/AS and a destination IP/AS. BGPlay is very helpful though.

At least in Debian and Ubuntu Linux there is a traceroute utility that
gives path ASN's. It is ironically called traceroute-nanog. If I do a
`traceroute-nanog -AO $destination` I get all the ASN info.

I find Perry Lorier's traceroute mesh server (http://tr.meta.net.nz) in "Grouped by AS" mode (do a "Full Traceroute" first to find the Grouped by AS option) pretty useful as a general "how do other people reach us?" tool. I don't think it's exactly what you want, but could possibly be something to start with?
