Speaking as a small ISP with 10 to 20 Gbps peak traffic. We are heavy inbound as a pure eyeball network. We use the route servers. We only maintain direct BGP sessions with a few large peers. Think Google, Netflix, Akamai etc. The reason for this is simply administrative overhead. Every BGP session has to be configured and monitored. We know that it will not move a large percentage of our traffic. We simply do not have the ressources currently when the gain is so little. Anyone who wants to pass traffic efficiently to us can either use the route server or they can peer with Hurricane Electric. The later option will get the traffic to us almost as efficiently as peering directly with us. In this sense we outsourced the peering to them.

Hello,
Newbie question, what criteria do you look for when you decide that you want to peer with someone or if you will accept peering with someone from an ISP point of view.
Thanks.
