Coriant Study Finds New Capacity and Service Delivery Requirements are Driving the Evolution of Mobile Backhaul

Heavy Reading White Paper Reveals Findings from a Survey of Mobile Network Operators

NAPERVILLE, Illinois, 23 February 2015 – A new white paper – New Drivers and Roadmaps for Mobile Backhaul Evolution – prepared by Heavy Reading, on behalf of Coriant, reveals that mobile operators are keenly focused on new ways of improving the performance of mobile backhaul (MBH) networks to deliver better service. Based on a survey of 75 mobile operators around the world, the findings highlight the key trends and attributes transforming mobile backhaul networks including Software Defined Networking (SDN), continued use of IP/MPLS, and increased use of fiber.

SDN is seen as a promising means of addressing backhaul network challenges such as congestion that directly impact end-user Quality of Experience. Sixty-three percent of respondents identified different types of optimized network routing as the lead use case for SDN in the backhaul. Nearly three quarters expect to hold trials of SDN in the backhaul in the next two years and a full 85% expect live deployments in the 2018-2019 timeframe.

The survey shows that mobile operator respondents expect greater use of IP/MPLS and that this will have a substantial impact on the backhaul. As highlighted in the white paper, key drivers for deployment of IP/MPLS include increased traffic volumes, user demand for Layer 3 VPN services, and use of mesh-based architectures in the backhaul, as well as increasing requirements for Quality of Service and advanced phase synchronization.

The exploding demand for mobile services also prompted nearly two thirds of mobile operator respondents surveyed to state that their company will need unbundled fiber access services (either wavelengths or dark fiber) to serve cell sites. Similarly, over half of respondents also predicted continued or increasing demand for routers at cell sites to extend IP/MPLS intelligence to the network edge.

"This survey reveals that operators are positive about the potential of SDN in the backhaul and that optical networks are central to the next phase of backhaul evolution," said Patrick Donegan, Chief Analyst, Heavy Reading. "The coming years will also see specific services begin to drive backhaul network evolution."

"Mobile operators will require advanced IP/MPLS and SDN solutions to transform the mobile backhaul network to support LTE-Advanced and new services," said Paul Smelters, Senior Vice President of Data Networks, Coriant. "Coriant continues to shape the evolution of mobile backhaul with our scalable portfolio of 8600 Smart Router solutions and innovations in SDN that create the foundation for highly programmable and service-aware networks."
