What is the difference between peering and IP Transit?

Peering, better stated as IP peering is the agreed-upon exchange of data between two ISPs and the amount of data exchanged is generally very close to equal. IP transit is when one entity pays another for the right to transit its upstream network. This removes the need for either party to pay a third party.

In most cases, the relevant ISPs do not charge for this agreement because both parties will share the benefit of the arrangement so this procedure is termed “Settlement Free.” It is a basic agreement by both parties to establish a no-charge exchange.

IP Transit
In the activity of IP Transit, a designated service ISP enables traffic to move through their network to its final destination. No matter how your business connects to the Internet, you will need to use IP transit to some degree.

Breaking it down
In terms of a peering lifecycle, a helpful point of view is from a routing standpoint. In specific terms, the routing network exchange between routing peers. Moving through the lifecycle. the received routes become more concise as the destinations become more concise.

You must be very careful to maintain routing equipoise because of the potential for several types of peering based on data flows to discrete destinations. Entities must remember that peering is a mutual agreement so collocation and IX providers are in place to allow for a connection. That said, organizations should keep in mind that these connections must be of mutual agreement so a fair amount of research into each entity is recommended.

The Internet is made up of over 25,000 independent systems that autonomously route the movement of traffic. Peering is often utilized as a conduit for the interaction and synergy of traffic to move over the Internet from one end-user to another end user.

When enterprises are connected, peering is essential for all Internet Service Providers, Content Delivery Networks, and backbone service providers.
