Definition: A Tier 1 ISP is an ISP that has access to the entire Internet Region solely via its free and reciprocal peering agreements. Definition: An ISP is entity that provides (usually sells) access to the global Internet.

In practical terms, a tier 1 network is one of the few networks that are large enough that they do not need to pay other tier 1 networks in order to use their networks, and charge smaller networks for access to their network. A tier 1 network is not to be confused with a T-1 line. The Tier 1 networks, in combination, form the backbone of the internet. They are large enough to support peering agreements amongst themselves, so internet traffic can go across any of their networks. Whenever possible, though, a Tier 1âs own network traffic has the highest priority on its own network.
