Internet Exchange Points

The term “Internet Exchange Point” (IXP or IX) is often used interchangeably with ‘Exchange Point’ (EP), “Internet Peering Point” (IPP), and “Network Access Point” (NAP). While there are no formally agreed definitions for these different terms, the most commonly
used are IXP, IX or ‘peering point’. NAP is an older term, originally used for the original four exchange points in the US which provided access to the Internet backbone operated by the National Science Foundation (NSFNET), prior to the global development of the
Internet.

Internet Exchange Points are a vital part of this system. Without them, the Internet would not function efficiently because the different networks that make up the Internet would need to directly interconnect with every other network in order to be able to exchange
traffic with each other. For Internet providers and users, there are many advantages to local routing of Internet traffic via a common exchange point:

  • Substantial cost-savings are made by eliminating the need to put all traffic through the more expensive and often slower or more congested long-distance links to the rest of the world.
  • More bandwidth becomes available for local users because of the lower overall costs of capacity.
  • Local links are much faster (often up to 10 times) because of the reduced latency in the traffic which has to make fewer hops to get to its destination.
  • New local content providers and services that rely on high-speed low-cost connections become available, further benefiting from the broader user-base available via the IXP.
  • More choices for Internet providers become available via the exchange point to send their upstream traffic to the rest of the Internet, making the wholesale transit market smoother and more competitive.
