Peering Request - basic principles
When a network gets to a certain size, it is worth to start peering. As a rule, no money changes hands in a peering relationship. All over the globe there are Internet Exchanges (IXes) that help people who want to peer connect to each other.
Smaller networks commonly want to peer with everyone, but big networks only want to peer with other big networks. The goal of the peering request is to make it easy for the other party to say “yes” as possible. Key to successful establishment of peering partnership is respecting peering request etiquette.
The first rule to respect when emailing peering requests is using a subject line like this: “Peering request from Me (AS65700) to You (AS64939)”. Your message must explain who you are and why peering with you is a good idea.
