LINX Builds High-Performance Network Architecture with Juniper Networks to Manage Exploding Traffic Levels

PTX Series Packet Transport Switch Slated to Power One of the World’s Largest Internet Exchanges with a Converged Supercore for Scale, Simplicity & Efficiency

London Internet Exchange Ltd. (LINX) and Juniper Networks (NYSE: JNPR), the industry leader in network innovation, today announced that LINX, a mutually-owned membership association for operators of Internet Protocol networks and one of the world’s largest Internet Exchanges, is building a new network based 100 percent on Juniper Networks technology. The network, being built in two phases, will enable LINX members to interconnect and share video, cloud and other content-rich traffic reliably, rapidly and cost-effectively across fixed and mobile offerings.

The first phase of the new architecture will comprise Juniper Networks® MX Series Ethernet Services Routers, and Junos® Space, Juniper Networks' programmable network application platform. Junos Space Network Activate, an MPLS network automation application, is also being deployed within the first phase. Network Activate is designed to enable LINX to automate the configuration, monitoring, management and trouble-shooting of its MPLS services, making it highly responsive to user and application requirements. The second phase, scheduled for deployment in the first half of 2012, is slated to include Juniper Networks PTX Series Packet Transport Switches and will run on Junos OS, Juniper’s single operating system in common with the phase 1 deployment.

"We believe a huge proportion of the UK’s traffic passes across our infrastructure with LINX passing approximately 1.5 Terabits per second of traffic at peak, and our members expect consistent, reliable throughput. The architecture will allow us to offer a sophisticated carrier platform from which we can launch new services such as VLAN tagging and 100G ports," said John Souter, LINX’s chief executive officer. "We've chosen Juniper as our desire to build a layer three platform led us to a vendor with a reputation for robust, carrier-grade networks, and their ability to provide high-performance at scale. Traffic levels are only going in one direction – next year we have to factor in even more growth resulting from the Olympics bringing the world to London – so our investment in Juniper enables us to build a fast, cost-effective platform for the long-term good of our members and their customers."

The LINX infrastructure comprises 10 Points of Presence (PoPs) across London, from Docklands in the East to Slough in the West. The MX Series will be deployed within these PoPs and in the core. The PTX Series is designed to create a Converged Supercore™, uniquely able to combine native MPLS packet switching and optical transport capability end-to-end within a single network layer. It can help organizations like LINX to manage evolving traffic patterns effectively and economically. End user demand for high-quality content across an array of devices and access technologies puts increasing pressure on LINX members to deliver richer, faster services while facing falling revenues. The new platform will help LINX remain one of the few areas of their members’ business where operational costs will continue to fall rather than rise.

The LINX deployment is being facilitated by Juniper Networks' local partner, Telindus Ltd.

"This is a significant opportunity to showcase the relevance of Juniper's new network innovation at the sharp end of the carrier industry, at a time when user experience, cost reduction and data complexity are creating a 'perfect storm' for the service provider community," said Sean Dolan, senior vice president EMEA, Juniper Networks. "By utilizing strategic elements of our carrier portfolio—MX Series and PTX Series—LINX can enhance its service and transport capabilities from end to end. Juniper's Trio and Express silicon technologies, from Edge to Converged Supercore, are designed to help LINX transform the experience and economics of networking for its members."
