Editing London Internet Exchange (section)

==Technology==
In [[London]], LINX operates two physically separate networks, or [[network switch|switching platforms]], on different [[Computer architecture|architecture]]s using equipment from different manufacturers ([[Extreme Networks]] and [[Juniper Networks]]<ref>{{Citation |title=London Internet Exchange (LINX) and Juniper Networks: Moving Traffic at 2 Terabits Per Second |url=https://www.youtube.com/watch?v=2NbYUks0AjI |language=en |access-date=2022-06-09}}</ref>). These networks are deployed over ten locations, each connected by multiple [[100 Gigabit Ethernet]] or [[10 Gigabit Ethernet]] connections over [[Optical fiber|fibre]] networks.<ref name=LINX>{{cite web|title=LINX Network Topology|url=https://www.linx.net/tech-info-help/network-topology|publisher=London Internet Exchange|access-date=13 January 2017|archive-date=15 February 2017|archive-url=https://web.archive.org/web/20170215123512/https://www.linx.net/tech-info-help/network-topology|url-status=dead}}</ref>

The LINX Engineering team restructured its secondary LAN in London, LON2, in 2018 using software and hardware from two different suppliers.

LINX data center facilities are found at sixteen locations throughout London, including:

*[[Telehouse North]]
*Telehouse North 2
*[[Telehouse East]]
*[[Telehouse West]]
*[[TelecityGroup|Equinix Harbour Exchange]] (ex. TeleCity)
* Digital Realty, Bonnington House, Millharbour (ex. TeleCity)
*[[TelecityGroup|Digital Realty, Sovereign House]], Marsh Wall (ex. TeleCity)
* Equinix Powergate, Acton
*[[Equinix]], Slough
*[[Interxion]] London City
*Virtus, Hayes (Transmission PoP)
*Colt Data Centre, London West (Transmission PoP)

Connecting is also possible from remote locations via the 'LINX from Anywhere' scheme<ref>{{cite web|title=LINX Anywhere|url=https://linx.net/join/linxanywhere.html|access-date=26 October 2013|archive-date=29 October 2013|archive-url=https://web.archive.org/web/20131029205828/https://linx.net/join/linxanywhere.html|url-status=dead}}</ref> via a range of layer 2 service/MPLS carriers.

Redundancy of the network is managed using rapid-failover protection mechanisms such a VPLS service over an MPLS core (MPLS/VPLS) from Juniper and Extreme's [[Ethernet Automatic Protection System]] (EAPS). These restore connectivity within tenths of a second in the event of the loss of a network segment.

In addition to the main peering infrastructure, LINX provides managed private interconnections (via [[Single-mode optical fiber|Single Mode Fiber]]) between LINX members, and works with a number of fibre carriers to provide rapid connection between LINX members for private circuits. These PI circuits may be used for any purpose, but are mainly intended for [[Peering|Private Peering]] arrangements between members. Private Peering is sometimes more appropriate for managing large flows of traffic between ISPs and/or Content Providers.

Telehouse hosts the vast majority of internet peering traffic from LINX.<ref name=":0">{{Cite web |title=Telehouse opens $177 million London Docklands data center |url=https://www.datacenterdynamics.com/news/telehouse-opens-177-million-london-docklands-data-center/ |access-date=2019-03-29 |website=www.datacenterdynamics.com |language=en}}</ref>
