Liberty Global Selects Benu Networks’ Dual Stack Solution for Seamless Migration to IPv6


Benu Networks’ Virtual Service Edge Platform Will Help Future Proof Liberty Global’s Network

BILLERICA, MA. (BUSINESS WIRE) – February 22, 2018 – Benu Networks, a leading provider of innovative virtual network solutions that enable service providers to rapidly create and deliver next generation IP services, today announced that Liberty Global, the world’s largest international TV and broadband company, has purchased Benu Networks’ IPv6 Dual-Stack (DS-Lite) solution.  Benu Networks’ Virtual Service Edge (VSE)  platform is the foundation of the DS-Lite solution which allows broadband service providers, such as Liberty Global, to transition to IPv6 without impacting existing subscribers’ use of IPv4 Internet or applications.

In addition, Liberty Global and Benu Networks partnered with ARRIS International plc. (NASDAQ: ARRS), for strategic architectural design expertise, integration, and deployment of the Benu Networks’ DS-Lite solution by the ARRIS Global Services team.

he DS-Lite solution provides a standards-based Address Family Transition Router (AFTR) capability per the IETF RFC6333 standard deployed on Benu Networks’ latest, high-performance, x86 Multiservice Edge Gateway (xMEG) platform.  In addition to standard AFTR functions, the solution supports a robust provider edge routing feature set (e.g. MP-BGP, 6PE, MPLS) for tighter integration while also helping to future proof Liberty Global’s network.  Utilizing a software upgrade, the VSE platform running the DS-Lite solution can easily transition to a virtual customer premises equipment (vCPE) solution to deliver Managed Business Network or Managed Home Network services. This supports Liberty Global’s GIGAWorld initiative announced in November 2016, which aims to accelerate the digital revolution in Europe.

Benu Networks’ IPv6 DS-Lite solution offers an innovative architecture with robust capabilities. Based on proven technology that is readily available to Liberty Global, and which integrates with their broadband customer premises equipment (CPE) (e.g. cable modems, xDSL modems), the Benu Networks’ solution:

  • Provides dual-stack to users without requiring any public IPv4 address to be assigned to the CPE, thus streamlining the deployment and management of IPv4.
  • Employs IPv6 in the access network to ease the IPv4 exhaustion issue and simplify the management of the access network.
  • Supports native IPv6 traffic in the ISP core network which further promotes the adoption of IPv6.
  • Delivers a future proof network which does not require new hardware to enable new network functions/services such as a Virtual Services Gateway.

“Liberty Global selected Benu Networks’ DS-Lite solution for its technical, operational, and commercial fit.  Even more compelling was the solution’s ability to support the creation of different network service slices on the same platform,” stated Andrew Grotzke, Vice President of Core Networks, Strategy and Engineering, Liberty Global.  “This capability will empower Liberty Global to easily and rapidly launch additional managed services in the future. The team at Liberty Global is glad to again partner with Benu Networks on enabling a mission critical network service that will assist us with our transition from IPv4 to IPv6.”

“ARRIS collaborates with Liberty Global across the operator’s global operations giving us the insights and expertise to seamlessly integrate Benu Networks’ DS-Lite solution,” said Steve McCaffery, President of International Sales, ARRIS. “This deployment is testament to our leadership in designing and transforming today’s broadband networks, leveraging innovative technology from strategic partners, and ARRIS’ world-class engineering bench.”

“Benu Networks is pleased to continue our collaboration with Liberty Global and ARRIS to provide a cost effective and powerful IPv6 DS-Lite solution,” stated Mads Lillelund, CEO, Benu Networks.  “At the heart of the DS-Lite solution is Benu Networks’ Virtual Service Edge (VSE) software platform which supports the creation of different network service slices on the same, single platform. This empowers Liberty Global with the flexibility to utilize the same VSE platform used to address the seamless transition from IPv4 to IPv6, to enable the delivery of other additional applications such as Managed Business Network services.”
