CORRECTING and REPLACING IXLeeds Selects Cumulus® Linux® Operating System to Power Upgraded Internet Exchange Point

In the fourth paragraph of release dated March 24, 2014, the parenthetical hyperlink for R-Com has been updated.

The corrected release reads:


Open ecosystem where businesses can choose between various industry standard networking gear, network operating systems and network applications gains further industry support

Cumulus Networks, the company bringing the power of Linux to networking, today announced that IXLeeds, a not-for-profit Internet Exchange Point (IXP) based in Leeds, UK, has selected the Cumulus Linux operating system for the company’s upgraded Internet Exchange Point. The successful deployment followed a three-way bid, with the company being selected over Extreme Networks and Juniper Networks.

IXLeeds ( was launched in September 2010 in order to allow public peering in the north of the United Kingdom. It aims to help its members — including companies such as Akamai — to increase their network resilience and reduce overall traffic backhaul costs towards London.

The company began evaluating new solutions in late 2013 when their existing Brocade BigIron RX-8 system, which was first installed when the project began, could no longer meet their requirements. After a review of the system, which uncovered a lack of support combined with a lack of automation tools and high levels of power consumption, the IXLeeds team decided to upgrade the Internet Exchange Point.

Cumulus Networks’ solution includes 1G Quanta and 10G Edge-Core Ethernet switches both of which are provided by R-Com ( and Hammer plc ( The no-compromise solution was a clear advantage as Cumulus Networks’ disaggregated model allowed for the optimal selection of hardware and software at a fraction of the cost compared to traditional networking options.

In addition, by selecting Cumulus Linux, the industry’s first fully-featured Linux operating system for networking hardware, the company can now run the latest Linux applications and automation tools, delivering new levels of agility, scalability and flexibility to the network.

Thomas Mangin, IXLeeds Technical Director, who led the selection process, commented: “Cumulus Networks was able to develop and deliver a solution that exceeded our expectations. Their strong involvement during the tendering and design stage has been invaluable. Their team has been unparalleled in terms of responsiveness and expertise. We were able to select a hardware combination that fits with our current and planned requirements. The open nature of the product will allow us to use a variety of tools to gain automation at the exchange itself. Incredibly, the solution not only surpassed all requirements but also came under budget.”

“We’re delighted with the success of the solution we have been able to offer IXLeeds. It is a fantastic example of how the Linux networking model is being embraced by companies across the globe,” said Reza Malekzadeh, Vice President of Business, Cumulus Networks. “The open approach we take means customers get the right degrees of freedom, transparency and choice when selecting networks. We are seeing tremendous demand for this type of offering, as illustrated by recent announcements with Dell and Hammer, and we look forward to continued success.”
