Although 5G standardization has not yet started, Nokia already has demonstrated several proof of concepts related to SDN. Meanwhile, the vendor says it is taking a holistic approach to operators' future 5G architecture needs. Its programmable 5G architecture overcomes the "rigidity of legacy networks," the company says. "Operators will be able to offer network functions to any kind of industry under a Network-as-a-Service business model."
The company outlined five key architecture functionalities it is delivering, including: network slicing, dynamic experience management (DEM), service-determined connectivity, fast traffic forwarding and mobility on demand.
Peter Merz, head of Radio Systems for Nokia Networks' Technology & Innovations group, points out that 5G is not just about the radio -- it's about the architecture and all the other things, including transport, where SDN comes into play. "This is part of our overall holistic approach" to 5G, he toldFierceWirelessTech.
U.S. operators may be particularly interested in the DEM, where automatic Quality of Experience (QoE) optimization of each application session provides "superior customer experience" even under high network load using up to 30 percent fewer resources. DEM can be deployed already in today's networks.
That's achieved using a self-organizing network (SON) for transport solution in combination with a multivendor SDN fabric control that acts across SDN domains. The network control doesn't need to talk to every SDN controller because a single Rest Application Programming Interface (API) is used.
Nokia also is introducing programmable APIs to the virtual core network elements in order to adapt core network behavior in run time. "This is a clear step forward as today's elements require hours or even days to be re-configured," Nokia said in its release. "As a result, the core network can adapt to dynamically changing needs such as the creation of new network slices or mobility profiles either immediately or on demand."
