The process of transferring the network traffic of small ISP to the larger internet is known as IP transit. Two things are generally done IP transit. The first service is all about sending the network routes to all similar smaller networks (ISPs), so that the former network can receive the network traffic of the latter.
The second service is the reverse of the first; here all the other networks send their network routes so that the first network can send its network traffic. 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 are formulated as per megabit per second for every month. The customers of this type of service usually have to fix the amount of bandwidth use over a period of time for payment. Different regions have different bandwidth prices.
Tier 1 IP transit is the process of IP transit on a Tier 1 network. 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. Do not get confused that all networks that are transit free are also Tier 1 networks; they are not. Sometimes transit free is achieved by agreeing to settlements and 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. If one follows the exact definition of Tier 1 network then no Tier 1 network can be found. This is why in the business world Tier 1 networks are known as networks without explicit settlements.
A network that does both peering, IPtransit redbus and also purchases some settlements is known as Tier 2 network. More specifically it is an ISP that does both peering and explicit settlements. The term peering means two networks exchanging each other networks traffic or is conducting data transit. Here the networks generate income from its own customers rather than from each other. The word peering has some misconceptions due to its extensive use in the business world where it is referred to as settlement free. The technical term is as simple as swapping the network traffic.
Tier 2 networks are much more common on the net due to their versatility. Most ISPs go for Tier 2 network because in Tier 1 they have purchase IP transit even after peering. Tier 3 network is a network that pays to other networks to gain access to the internet. A Tier 3 network typically is a single computer that gets its access from a local ISP.
