The process of transferring the network traffic of small ISP to the larger internet is known as IP transit. IP transit is made up of two packaged services. The first thing is to broadcast the network routes to all the other ISPs, so that every node of the first network can receive traffic from them.
The second task is exactly the opposite, so that the first network can send network traffic to others after receiving the network routes. Tier 1, Tier 2 and Tier 3 IP transit supplier means agents or companies that provide the service in respective network structures. The bandwidth prices for this service are paid as per megabit per second for each month. In general the customers of this service have to pay for a minimum amount of bandwidth over a fixed amount of time. Different regions have different bandwidth prices.
Using a tier 1 network for IP transit is called a Tier 1 IP transit. All tier 1 networks are known as settlement-free peering because they can reach every other network without paying for IP transit or data transit. To elaborate, in a way all Tier 1 network is transit free as long as they interact with other Tier 1 network. It does not mean that just because a network is transit free, it must be a Tier 1 network. An ISP can become transit free by peering. If the business agreements of a network are not set as public information, it is hard to tell whether or not it is paying settlements. Often when the information is not public the network has a non-disclosure agreement. The peering community consists of peering coordinators from the internet exchanges. The list of all Tier 1 networks is not formally published. All Tier 1 networks out there has minor alterations from the original definition. Tier 1 networks are more commonly known as networks without explicit settlements in the business world.
A network that is involved in both peering and purchasing for example IP transit redbus is classified as a Tier 2 network. To be more specific, it may be an ISP that does both peering and overt settlements. When two networks perform data transit or exchange each other's network traffic it is called peering. In peering the networks do not need to pay each other but generate revenue from their respective customers. Since the term peering is used in the business world extensively, it has somewhat lost its technical meaning. The technical term of peering is as simple as swapping the network traffic of two networks.
These networks are much more common than Tier 1 networks because of its benefits. For ISPs it is much easier than Tier 1 networks because of the settlement issue. A Tier 3 network purchases IP transit for all networks. A Tier 3 network typically is a single computer that gets its access from a local ISP.
