RE: Choosing new transit: software help?

  • From: Sam Hayes Merritt, III

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.
Flowscan will do this. Origin and path.

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 know most nanog responses seem to go off list immediately
but I'd be interested in this as well for traffic engineering.

A top AS and top prefix talkers would be really useful.
Flowscan will do the top AS, out of the box.
It could be hacked to go further.
