Editing Internet exchange point (section)

===Technical operations ===
A typical IXP consists of one or more [[network switch]]es, to which each of the participating ISPs connect. Prior to the existence of switches, IXPs typically employed [[fiber-optic inter-repeater link]] (FOIRL) hubs or [[Fiber Distributed Data Interface]] (FDDI) rings, migrating to [[Ethernet]] and FDDI switches as those became available in 1993 and 1994.

[[Asynchronous Transfer Mode]] (ATM) switches were briefly used at a few IXPs in the late 1990s, accounting for approximately 4% of the market at their peak, and there was an attempt by [[Stockholm]]-based IXP [[NetNod]] to use [[SRP/DPT]], but [[Ethernet]] has prevailed, accounting for more than 95% of all existing Internet exchange switch fabrics.  All Ethernet port speeds are to be found at modern IXPs, ranging from 10 [[Megabit|Mb]]/second ports in use in small developing-country IXPs, to ganged 10 [[Gigabit|Gb]]/second ports in major centers like Seoul, New York, London, Frankfurt, Amsterdam, and Palo Alto. Ports with 100 Gb/second are available, for example, at the AMS-IX in Amsterdam and at the DE-CIX in Frankfurt.{{Citation needed|date=August 2021}}
