What is the difference between peering and settlement free peering?
Peering. Occasionally the word "peering" is used to describe situations where there is some settlement involved. In the face of such ambiguity, the phrase "settlement-free peering" is sometimes used to explicitly denote pure cost-free peering.
What is ISP peering?
ISP peering is the business relationship ISPs engage in to reciprocally provide access to each others' customers using their networks. A key characteristic of an ISP peering relationship is that it is settlement-free peering.
What is the meaning of peering?
In computer networking, peering is a voluntary interconnection of administratively separate Internet networks for the purpose of exchanging traffic between the users of each network. The pure definition of peering is settlement -free, also known as "bill-and-keep," or "sender keeps all," meaning that neither party pays the other in association ...
What is private peering and how does it work?
Private peering is the direct interconnection between only two networks, across a Layer 1 or 2 medium that offers dedicated capacity that is not shared by any other parties. Early in the history of the Internet, many private peers occurred across "telco" provisioned SONET circuits between individual carrier-owned facilities.
What is paid peering?
Paid peering is the relationship where two networks exchange traffic with payment. • Paid peering provides access to another network without having to pay a third party.
What is peering agreement?
A peering agreement is an agreement between two network administrators to share data routing responsibilities across multiple networks. Peering is a mainstay of the global Internet and large data mobility systems.
Does peering cost money?
Usually, the smaller of the two pays fees to the larger, who maintains the infrastructure. If the two users are exchanging an equal amount of traffic, fees may be waived. Internet peering allows an exchange of traffic in both directions for free. Peering networks have hundreds of members.
What is the purpose of peering?
Peering is a process by which two Internet networks connect and exchange traffic. It allows them to directly hand off traffic between each other's customers, without having to pay a third party to carry that traffic across the Internet for them.
What is an example of peering?
She leaned down; peering through the soot smudged glass on the stove door. He rubbed his eyes and sat up, peering at the clock. Rhyn rose and crossed to the small cave, peering into its depths.
What is a peering issue?
Peering issues can also be specific between carriers and not across all of the peering paths. For example, a new release of software for routers in Carrier A has an issue with the router software in Carrier B. The result is a significant degradation in capacity and latency across the peering connection.
Is public peering free?
Most traditional peering arrangements are settlement-free. This is not to say peering is without costs—some fixed costs are always involved, including peering ports, colocation, power, and various equipment costs.
What is the difference between private and public peering?
Public Versus Private Peering Public peering is usually carried out through an Internet Exchange Point (IXP), where one network can peer with multiple other networks through a single connection. Private peering is when two or more networks agree to exchange their traffic at a private facility.
What is the difference between transit and peering?
Peering: when two or more autonomous networks interconnect directly with each other to exchange traffic. This is often done without charging for the interconnection or the traffic. Transit: when one autonomous network agrees to carry the traffic that flows between another autonomous network and all other networks.
What is the difference between peering and interconnect?

What is a peering location?
ExpressRoute locations (sometimes referred to as peering locations or meet-me-locations) are co-location facilities where Microsoft Enterprise Edge (MSEE) devices are located.
What is direct peering?
What is Direct Peering? As the term suggests, direct peering is a voluntary interconnection of two separate networks for the purpose of exchanging traffic directly between the users of each network.
What is peering in data centers?
Peering is the exchange between two independent networks for the benefit of both networks.
What is peering in AWS?
Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you've defined. A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses.
What does it mean to peer at something?
intransitive verb. If you peer at something, you look at it very hard, usually because it is difficult to see clearly. I had been peering at a computer print-out that made no sense at all. countable noun. Your peers are the people who are the same age as you or who have the same status as you.
What does peering eyes mean?
1. verb. To look intently and fixedly: eye, gape, gawk, gaze, goggle, ogle, stare.
How does peering reduce costs?
Reduced costs — ISP Peering can reduce the costs of routing traffic between individual networks. For example, if an ISP exchanges a significant amount of customer traffic with another ISP, rather than sending that traffic up through its transit provider and into the other network through their transit connection, the two networks could peer at a shared facility, and each eliminates the transit cost for that traffic exchange.
What is peering ecosystem?
The global Internet peering ecosystem is a loosely coupled set of these Internet Regions each with its peering ecosystem.
Why is ISP peering important?
Reduced costs — ISP Peering can reduce the costs of routing traffic between individual networks.
What happens when two ISPs peer?
In the peering case, two ISPs only exchange the routes of their downstream customers and neither can see the other's upstream routes over the peering connection. If an ISP peers with another ISP, the two agree to exchange traffic only between their endpoints and the endpoints in their customers' networks. This is in contrast to IP transit, ...
Why do ISPs peer?
ISP Peering Benefits. Network operators may be motivated to peer for a variety of reasons, both business and technical. The motivations for peering networks can include: Network reachability — Any network is not particularly useful if no one connects to it or those who connect to it cannot reach each other. Increased redundancy — ISPs strive ...
What is ISP peering?
ISP peering is the business relationship ISPs engage in to reciprocally provide access to each others' customers using their networks. A key characteristic of an ISP peering relationship is that it is settlement-free peering. However, the costs are not zero, because there are costs associated with private co-location, ...
Is peering cost zero?
However, the costs are not zero, because there are costs associated with private co-location, the power to the routers and switches, cross-connects that are consumed to implement the peering connectivity.
What is paid peering?
The concept of paid peering is similar to transit in the sense that one network operator is paying another for access, but while a transit purchase enables access to the whole internet via the transit partner’s network, paid peering only grants the customer access to that provider’s network.
Where can peering take place?
This can be done in privately-owned telecom facilities, where a circuit can link directly from one network’s point of presence (PoP) to the other’s. Private peering can also take place in a public location such as a colocation facility.
Why is public peering important?
Public peering is particularly well suited for interconnections between minor peering partners, because the IX enables connected ISPs to exchange traffic with a wide range of operators via a relatively small number of ports.
What happens when traffic volumes between peering partners become unbalanced?
If the traffic volumes between peering partners become unbalanced, with one side sending the other a disproportionate amount of traffic, the parties can agree to migrate to a paid peering arrangement.
Is peering settlement free?
Most traditional peering arrangements are settlement-free. This is not to say peering is without costs—some fixed costs are always involved, including peering ports, colocation, power, and various equipment costs.
Why is "settlement free peering" used?
In 0.02% of cases the word "peering" is used to describe situations where there is some settlement involved. Because these outliers can be viewed as creating ambiguity, the phrase "settlement-free peering" is sometimes used to explicitly denote normal cost-free peering.
What is public peering?
Public peering is accomplished across a Layer 2 access technology, generally called a shared fabric. At these locations, multiple carriers interconnect with one or more other carriers across a single physical port. Historically, public peering locations were known as network access points (NAPs). Today they are most often called exchange points or Internet exchanges ("IXP"). Many of the largest exchange points in the world can have hundreds of participants, and some span multiple buildings and colocation facilities across a city.
What is peering in computer networking?
In computer networking, peering is a voluntary interconnection of administratively separate Internet networks for the purpose of exchanging traffic between the "down-stream" users of each network. Peering is settlement -free, also known as "bill-and-keep," or "sender keeps ...
Why is public peering important?
Since public peering allows networks interested in peering to interconnect with many other networks through a single port, it is often considered to offer "less capacity" than private peering, but to a larger number of networks. Many smaller networks, or networks which are just beginning to peer, find that public peering exchange points provide an excellent way to meet and interconnect with other networks which may be open to peering with them. Some larger networks utilize public peering as a way to aggregate a large number of "smaller peers", or as a location for conducting low-cost "trial peering" without the expense of provisioning private peering on a temporary basis, while other larger networks are not willing to participate at public exchanges at all.
What is peering in a network?
By definition, peering is the voluntary and free exchange of traffic between two networks, for mutual benefit . If one or both networks believes that there is no longer a mutual benefit, they may decide to cease peering: this is known as depeering. Some of the reasons why one network may wish to depeer another include:
What is a donut peering model?
The "donut peering" model describes the intensive interconnection of small and medium-sized regional networks that make up much of the Internet. Traffic between these regional networks can be modeled as a toroid, with a core " donut hole " that is poorly interconnected to the networks around it.
Why do some networks use public peering?
Some larger networks utilize public peering as a way to aggregate a large number of "smaller peers", or as a location for conducting low-cost "trial peering" without the expense of provisioning private peering on a temporary basis, while other larger networks are not willing to participate at public exchanges at all.

I Introduction
Internet access providers (IAPs) have constructed massive network platforms to make end-users access the Internet and obtain data from content providers 1 1 1 We use the term ‘content provider’ in a broad sense that it includes Internet companies, e.g., Facebook [ 4] and Netflix [ 5], content delivery networks (CDNs), e.g., Akamai [ 1], and transit ISPs, e.g., Sprint [ 6].
Ii Network Model
In this section, we model a network platform built by an IAP, which transmits data traffic between CPs and end-users. In particular, the IAP can offer CPs two types of peering agreements, i.e., settlement-free peering and paid peering.
Iii Peering Schemes under Optimal Strategies
In the previous section, we constructed a network model under which the IAP can offer CPs differentiated peering types. Based on this model, we explore the optimal strategies that maximize the IAP’s profit or end-users’ welfare in this section.
Iv Sensitivities of Optimal Strategies
In the previous section, we analyzed the profit-optimal and welfare-optimal strategies, especially their corresponding peering schemes under certain network conditions. With the rapid development of the Internet, characteristics of the market participants, i.e., users, IAPs, and CPs, are continuously changing.
Vi Conclusions
In the paper, we model a network platform under which an IAP can offer CPs the paid and settlement-free peering to choose from and charge CPs of using paid peering and end-users. We capture the data delivery qualities of the peering types by their levels of network congestion and derive an endogenous system congestion in an equilibrium.
