Private peering is the direct interconnection between two networks. This connection leverages a medium OSI, layer 1 or 2, with dedicated bandwidth. Private peering is not shared by any other network or third party. Nowadays, most private interconnections are established at carrier hotels or carrier-neutral collocation facilities called meet-me rooms. These are facilities in which a direct cross-connection can be provided between participants that are located in the same building or at the same data center campus. These network-to-network interconnects usually have much lower costs than telecommunication circuits.
