SDN, NFV PoC includes Nokia, Aalto University, Coriant and EXFO
Nokia Networks has partnered with Finland’s Aalto University and vendors Coriant and EXFO on a proof of concept designed to tap software-defined networking and network function virtualization platforms to add agility and reduce costs associated with mobile backhaul services.
The entities said they have developed a European Telecommunications Standards Institute Industry Specifications Group for NFV proof of concept that shows a virtualized LTE network applying SDN technology to the mobile backhaul, transport and core network functions. The SDN-based platform is said to increase network economies due to the ability to use hardware for multiple functions.
Details of the PoC describe the transport and packet core being handled by standard switches and managed by centralized SDN controllers; all control software, including subscriber data and mobility management, running on generic data centers; and the LTE base stations remaining the only specific hardware component.
The platform is said to be using a Nokia LTE emulator that was created from a virtual evolved packet core with SDN technology, an LTE base station and terminals. Aalto University worked on integrating the virtualized LTE network components, while Coriant provided SDN switches, and EXFO provided probes for measurement and analysis.
The concept is being used as a platform to experiment in finding solutions that are in full compliance with the needs of mobile networks and the business impact of SDN for the “on-demand provisioning of new services.”
Infonetics Research released a report last year that found mobile operators are looking toward SDN and NFV to “provide greater backhaul flexibility and cost savings.”
The survey of 25 telecom operators across Asia, Latin America, North America, Europe, the Middle East and Africa, found 29% of respondents are deploying or plan to deploy SDN into their backhaul network “at some point.” A majority (63%) said they are evaluating the prospects, though have not yet set a timetable.
