LINX enhances its network with Transmode WDM installation

SEPTEMBER 15, 2009 -- The London Internet Exchange (LINX) has installed systems from Transmode to improve its network connectivity. Transmode TM-3000 units have been installed at four of LINX's London exchange sites to enable new high-speed WDM services that will help reduce the traffic pressure on LINX's network.

LINX is a mutual, not-for-profit organization whose 330 members include almost all UK Internet service providers (ISPs) and network operators plus many others from around the world. It was formed in 1994 when five ISPs recognized that there were considerable operational benefits to exchanging traffic between their networks at the same tele-hotel where they all had facilities. LINX has a network of 10 sites around London, seven in London's Docklands, plus one in the City, and two in West London, where it hosts a number of large Ethernet switches.

Transmode says that when it started discussions with LINX, the organization was considering the installation of WDM in the London network to enable it to cope with the demand for increased capacity. The decision was made to install an initial four Transmode TM-3000 units to support its highest traffic members that needed to pass through the exchange at rates up to and beyond 10 Gbps. The Transmode equipment installation was completed and then activated by early June 2009.

Mark Burton, Transmode sales director UK, commented, "Prior to the installation, Transmode provided a demonstrator at three key sites offering both 10G and Gigabit Ethernet services. Over the trial period, LINX performed comprehensive testing to observe how Transmode's systems functioned. LINX is very much focused on Ethernet over dark fiber so transport was a familiar domain to them."

Mike Hughes, LINX's CTO added, "We needed a way to handle the increasingly large traffic flows members pass between LINX sites. With some of these requiring multiple 10-Gbps links it was clear that offering an alternative to our Ethernet platform would benefit the exchange and our members.

"Following the installation of the Transmode equipment, LINX will be able to offer an extended range of services. The WDM approach will meet our members' requirement for increased capacity and flexibility," Hughes concluded.
