RETN deploys metro fiber-rings in London

London, United Kingdom – 22 October 2020 – RETN announces today it deployed metro fiber-ring topology in London to support incremental traffic growth to the key data centres on their metro area network and facilitate migration to 100G technologies. RETN customers will broadly benefit from the new ring-based architecture ensuring a greater resilience and availability of high-capacity IP-transit service delivered in shorter timeframes.

The network has developed from a single ring linking Equinix LD8 to Telehouse East, Global Switch, Interxion/Digital Realty, Equinix LD4/5/6/7 and back again into a dual ring architecture: Equinix LD8-Telehouse North 2-Equinix LD7 to bridge the main carrier hotels with a contiguous Infinera FlexILS platform connecting into mainland Europe, and Equinix LD8-DRT Docklands Campus-Interxion-Global Switch-Telehouse East to provide local access to major data centres across London (see diagram). The upgraded network is deployed using the Infinera FlexILS equipment and Juniper’s routers MX10003, MX204 and QFX switches on top.

“The recent development of our metro network in London allows us to more evenly distribute traffic between the nodes, vastly increasing the performance at each site, and thus combat technical limitations to facilitate up to 19 Tbps of 100G capacity on our metro network. Using the latest technology, we are providing our customers with the most resilient and cost-effective solution, so that they can get the best of the connectivity from Europe and locally even with the highest loads and increasing traffic demands,” – comments Andrey Gazizov, CTO and Managing Director of RETN in London.
