Vodafone and Huawei say they have conducted a successful field trial of fixed access network slicing, which partitions a physical FTTH network into multiple virtual network slices, creating multi-tenancy virtualization of the access network.
The trial was carried out at Vodafone Ireland with specialist Huawei teams supporting the joint initiative. Separate consumer and enterprise virtual network slices were created on a live FTTH network. The consumer slice carried broadband internet and Vodafone TV services whereas the enterprise slice carried OneNet business services including voice.
Fixed access network slicing gives flexibility and full control for different operations teams – whether they’re from different departments in the same company or from different service providers – to independently manage their own customers, even if there is only one physical access network.
For example, consumer and enterprise customers plus mobile backhaul connections can be securely provisioned and dynamically configured by their own respective operating teams. This allows converged operators to optimize their business practices and operational processes across different business areas. It also has the potential to facilitate new joint-venture and co-investment partner models for operating FTTH networks.
“Vodafone has deployed several FTTH networks around the world and many of these are with partners,” said Matt Beal, Director of Strategy & Architecture, Vodafone Group Technology. “Virtualization of the fixed access network will help us build and fill FTTH networks in a more cost-effective way that takes advantage of new operating models where both Vodafone and its deployment partners are able to differentiate their services over the shared fiber infrastructure.”
The architecture and equipment requirements for fixed access network sharing (FANS) were recently standardized by the Broadband Forum in its TR-370 Technical Report.
The virtual access network trial was carried out on Huawei’s MA5800 next-gen optical line terminal (OLT). The MA5800 uses a distributed architecture similar to a core router, which can partition a physical OLT into multiple logically-independent virtual OLTs. Different logical OLTs have independent hardware resources and software systems, and can be separately managed and configured.
“The solution can provide independent operation and maintenance management for multi-services bearing, and it can help to improve equipment efficiency, reduce operation and maintenance costs and achieve business success,” said Jeff Wang, President of Huawei Access Network.
