A Tier 1 carrier is a telco or ISP that is at the top of the telecommunications peering and settlements food chain.

Although there is no formal definition, the following generally holds

  • Tier 1 operators have operations in more than one country
  • Tier 1 operators own and operate their own physical networks, and either own or part-own their submarine international links.
  • Tier 1 operators have revenue-neutral peering agreements with other Tier 1 operators, and generally do not pay for transit.
