What Is Internet Peering?

The Internet Peering Playbook

The monthly transit bill increases even though the unit cost of transit decreases. One of the main drivers for pursuing an Internet Peering strategy is the decreasing of the absolute cost of Internet transit. The traffic to that destination is what is important to observe.

The control plane is connected to the data plane. The content providers that started peering all said that the end- user experience was the primary driver for peering, and that control over the route was the means to accomplish that. Hurricane Electric highlights all of the points across the globe in its marketing literature.

The marketing message is that the company takes responsibility for traffic all the way to the access networks and that it uses peering to provide better performance for customers. The first step is to identify the potential peering targets. The internet service providers determine where their traffic goes and where it comes from.

They are looking for peering partners that should be similarly incentivized to directly connect their network, to save money, to improve performance, etc., as shown in Figure 4-5. The relevant information is what peering requests need to include. Peering will be delayed or prevented if the e-mail messages fail to include the necessary information.

Including too much information is a problem, and it may be perceived as too burdensome. A real-world example of a poorly worded peering request is shown in Figure 8. The Internet Peering Playbook is available on the iPad at the Apple Store and on the Amazon Kindle.

Peering with Multiple Networks

Peering does not indicate how two networks are connected. The process could be started by running a circuit from one facility to another, but that method is inefficient when there are multiple peers. Public peering and private peering are two more efficient types of peering.

DE-CIX is a large Internet exchange. They can move almost 50 terabytes of traffic per second through their 18 locations. In 2015, Sandvine reported that 37% of all internet traffic in North America was from Netflix.

Private Peering: A New Method for Providing Free Traffic Exchange

Peering is a voluntary exchange of traffic between administratively separate Internet networks for the purpose of exchanging traffic between the "down-stream" users. Peering is settlement-free, also known as "bill-and-keep," or "sender keeps all," meaning that neither party pays the other in association with the exchange of traffic, instead each derives and retains revenue from its own customers. The Internet is a collection of networks that are autonomously connected, each with a unique set of global addresses and a BGP policy.

Public peering allows networks to connect to many other networks through a single port, which is often considered to offer less capacity than private peering. Many smaller networks, which are just beginning to peer, find that public peering exchange points are an excellent way to connect with other networks. Some larger networks use 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 private peering, while other larger networks are not willing to participate at public exchanges.

Private peering is a direct connection between two networks that is not shared by any other parties. Private peers occurred across the SONET circuits between the individual carrier-owned facilities. Most private interconnections are done at carrier hotels or carrier neutral facilities, where a direct cross connect can be done between participants within the same building, for a much lower cost than the telco circuits.

Peering with a Route Server in Netnod

Netnod has route server at its internet exchanges. A route server is used to facilitate peering arrangements. You can replace some or all of your BGP sessions with one single session towards the route server if you connect to the route server. It is easier for networks to manage peering arrangements with a route server, and it is also easier for new peers to start exchanging traffic at the exchange point.

Peering Service: A New Approach to Internet Access for Enterprise Users

Peering Service is a service that will provide public internet access to Microsoft for its enterprise customers. High throughput connections to Microsoft and HA connections are included in enterprise grade internet. The user traffic is designed to be fast to the nearest Microsoft Edge.

Direct Connection to the Internet Exchange

The switches that connect the networks are located at the heart of the Internet Exchange. Many networks have large ports that can transmit up to 400 Gigabits per second, and most networks have more than one to ensure redundantness. Through the simultaneous, direct connection to anywhere up to several hundred networks, connected networks can avoid congested transit routes and transmit data cost efficiently. The quality of the networks connected to the Internet Exchange can be improved through direct transmission and shorter routes.

Exchange Points: A Bad Place to Find Complete Internet Connection

Internet exchange points are not internet service providers. Exchange points are not a good place to find complete Internet connections. They are one of the building blocks that make up the internet.
