Public Peering

Definition: Public Peering is Internet Peering across a shared (more than two party) peering fabric.

Most Internet Exchange Points offer some form of public peering, typically using ethernet as the layer 2 fabric. In some cases, private peering is a reasonable alternative or complementary service.
