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 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.
