A Tier 1 network is an Internet Protocol (IP) network that can reach every other network on the Internet solely via settlement-free interconnection (also known as settlement-free peering). [1] [2] Tier 1 networks can exchange traffic with other Tier 1 networks without paying any fees for the exchange of traffic in either direction. [3]
They are widely used in the data center, ISP and cloud computing industries as part of the engineering design for high availability systems. The standard data center tiers are: [1] Tier I: no redundancy; Tier II: partial N+1 redundancy; Tier III: full N+1 redundancy of all systems, including power supply and cooling distribution paths
Tier 2 ISPs depend on Tier 1 ISPs and often have their own networks, but must pay for transit or internet access to Tier 1 ISPs, but may peer or send transit without paying, to other Tier 2 ISPs. Tier 3 ISPs do not engage in peering and only purchase transit from Tier 2 and Tier 1 ISPs, and often specialize in offering internet service to end ...
Internet service providers (ISPs) participate in Internet backbone traffic through privately negotiated interconnection agreements, primarily governed by the principle of settlement-free peering. The Internet, and consequently its backbone networks, do not rely on central control or coordinating facilities, nor do they implement any global ...
A Tier 2 network is an Internet service provider which engages in the practice of peering with other networks, but which also purchases IP transit to reach some portion of the Internet. [ 1 ] Tier 2 providers are the most common Internet service providers, as it is much easier to purchase transit from a Tier 1 network than to peer with them and ...
A transit free network uses only peering; a network that uses only unpaid peering and connects to the whole Internet is considered a Tier 1 network. [1] In the 1990s, the network access point concept provided one form of transit. [2] Pricing for the internet transit varies at different times and geographical locations. [3]
NSFNet Internet architecture, c. 1995. Internet exchange points began as Network Access Points or NAPs, a key component of Al Gore's National Information Infrastructure (NII) plan, which defined the transition from the US Government-paid-for NSFNET era (when Internet access was government sponsored and commercial traffic was prohibited) to the commercial Internet of today.
There are many arguments between ISPs, who traditionally support tiered services, and network neutrality proponents. ISPs state that tiered services are necessary to keep and maintain network performance. Also, tiered pricing schemes provide ISPs with an incentive to upgrade their networks and provide better service.
