What is an Internet exchange?
The Internet is the sum of all the individual networks around the world that interconnect to allow their users to exchange information with each other. These networks transfer data in one of two ways:
- IP Transit: A network operator pays to use the network of another operator to exchange Internet traffic.
- Peering: Two network operators agree to exchange traffic with one another for free.
Internet exchanges are locations that allow network operators to peer with one another. They are nearly always located in carrier-neutral data centres, where network operators can securely colocate in immediate proximity to the exchange’s IT infrastructure.
