LINX adopts disaggregated network architecture using EVPN on open hardware

The London Internet Exchange (LINX) migrated its LON2 platform to a new disaggregated network model that uses EVPN technology. The new architecture became fully operational on 5th June following an extensive testing, proof of concept, and migration process lasting nearly two years.

LINX is believed to be the first IXP globally to implement EVPN in its production fabric.

LINX said its new LON2 architecture employs EVPN over VXLAN, leaf-spine topology, full automation and is 100G ready.

LON2 is using IP Infusion’s OcNOS network operating system in concert with switch hardware from Edgecore Networks.

LINX is one of the world’s largest Internet Exchange Point (IXP) operators connecting over 820 networks from over 75 countries. It operates a dual-LAN infrastructure in London with regional exchanges in Manchester, Cardiff and central Scotland. It also operates an exchange in Northern Virginia, USA.

“By introducing a disaggregated platform, LINX members will benefit from increased flexibility plus continued value from their investment,” said Richard Petrie, LINX CTO. “The EVPN technology allows LINX to deliver long-term innovative technology to our members, a commitment to ever-greater levels of service quality and to allow us to provide services at a greatly reduced cost base.”

LINX Lead Architect, Flemming Heino, added, “With EVPN everything is programmed. Switches talk to one another, they are synchronised and ultimately more predictable and stable. The system offers many benefits and the flexibility for more features to be added such as multi-homing.”

George Tchaparian, CEO, Edgecore Networks, said, “There are many operational and cost benefits of the new architecture model and Edgecore are extremely proud to have worked with LINX on this ground-breaking project. We’ve clearly demonstrated that open network systems are ready outside of data centre applications and are viable solutions for mainstream telecom service providers."
