AWS could not miss the Mobile World Congress. On the occasion of the Barcelona fair, the cloud giant unveiled its novelties, all focused on the world of telecommunications. Collaboration with Nokia for Cloud RANs; the one with Aira, Juniper and VIAVI for a RAN Intelligent Control solution; the new services for monetize 5G networks.
AWS and Nokia join forces on Cloud RAN
At MWC Nokia and AWS presented a solution that leverages the power of the cloud from Amazon and the SmartNIC Cloud RAN of the Finnish company. Three objectives: reduce complexity; ensure top level performance carrier-grade on a single server; simplify the configuration and maintenance of radio access network (RAN) solutions.
As regards the reduction of complexity, it is necessary to start from the assumption that lately the telephone companies have abandoned the old approach to networks, and today use hardware and software from different manufacturers, so as to have more flexibility and be able to innovate faster. This approach is inevitably more complex to manage than hardware and software provided by a single manufacturer. Nokia and AWS plan to address this issue via a solution that allows Nokia RAN Containerized Network Functions to be performedvia Amazon EKS, on the AWS infrastructure installed on the data centers of the providers. The solution will be pre-validated and tested, saving CSPs months of testing.
More power and less consumption with Nokia In-Line Cloud RAN SmartNIC and Graviton3 CPUs from AWS
To enable advanced 5G scenarios on 5G networks, such as streaming VR and AR content, providers need to upgrade their infrastructure by adding new Massive MIMO radios. In doing so, costs and energy consumption increase. The idea of Nokia and AWS is to combine Nokia Cloud RAN SmartNICs with Amazon EC2 instances based on Graviton3 processors. Cloud RAN Smart NICs will handle RAN Layer 1 features, while Graviton CPUs will handle Layer 2 features, which require less computing power. Since both Gravitons and SmartNICs are based on ARM architecture, it is also possible reduce the energy consumption of the 5G Core network up to 70%.
The cloud to simplify software configuration and maintenance
5G networks are mostly software-based, and to manage them, CSPs need to keep thousands of network functions under control via containers. A job that can take a lot of time for technicians, who find themselves having to frequently write and update code. This is where automation services come into play such as AWSTNB And Amazon EKSwhich allow developers to greatly speed up some repetitive tasks, such as patching and network health checks.
