"Feeding" via some bigger peer networks oder classic transit
You have made the assumption that their choice is peering with your network or sending it out transit. They may in fact peer with your upstream. That makes their choice peer with you, or peer with your upstream. Peering with your upstream may allow them to reach many people like you for cost of managing only a single peering session, as compared to maintaining a few dozen. Also, many networks have minimum volume amounts for peering relationships. They may be able to get settlement free peering with your upstream by having some minimum traffic level that they would not have if they peer with some of the individual customers behind that upstream. Peering with you may drop them below the threshold, causing them to pay for transit on 10's of Gigs of traffic. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
