Build and Deploy GPU-Accelerated 5G Virtual Radio Access Networks (vRAN)
NVIDIA Aerial™ is an application framework for building high-performance, software-defined, GPU-accelerated, cloud-native 5G networks to deliver high performance to customers and improved total cost of ownership to service providers. Aerial supports GPU acceleration of the 5G stack and can be used for only physical layer 1 or the full stack. Aerial is the key building block Telco 5G vRAN, AI-on-5G, RAN-in-the-Cloud, and Aerial Research Cloud, and it can be trained in NVIDIA® Sionna.
Aerial SDK is in early access available as a .zip package as well as a container image for easy deployment via
NVIDIA NGC™
.
The NVIDIA Aerial SDK package simplifies building programmable and scalable software-defined 5G RAN. The Aerial SDK supports:
CUDA® Baseband (cuBB)
The NVIDIA cuBB SDK provides a GPU-accelerated 5G signal processing pipeline, including cuPHY for Layer 1 5G PHY. It delivers unprecedented throughput and efficiency by keeping all physical layer processing within the high-performance GPU memory.
CUDA Virtual Network Functions (cuVNF)
The NVIDIA cuVNF SDK provides optimized input/output and packet processing, exchanging packets directly between GPU memory and GPUDirect®-capable
NVIDIA ConnectX®-6 DX
network interface cards.
Designed to jump-start performance evaluation and benchmarking for RAN development, the integrated reference design provides preinstalled test vectors under the NVIDIA Aerial SDK and high-compute and signal processing power with NVIDIA GPUs and
DPUs
delivering an out-of-the-box guided experience. Key features include:
Preinstalled Aerial SDK and software environment
Test scripts that benchmark KPIs
Logged results of developer kit configuration, including hardware, environment, SDK, and sample test execution
Ability to exercise specific or all included test cases
The bring your own, bare-metal installation provides flexibility to use your own hardware setup and installing Aerial SDK to implement 5G RAN functions.
NVIDIA Aerial Research Cloud
Aerial Research Cloud is a research platform that enables usage scenarios and requirements for multi-terabit per second (Tb/s) cognitive 6G networks. It offers a fully programmable network architecture incorporating an intelligent plane to 6G wireless connectivity, AI and machine learning for autonomous networks, as well as innovative air-interface designs. The platform enables algorithm design for promising baseband technologies for the 6G ecosystem, including terahertz (THz) band communications, very-large-scale antenna arrays, reconfigurable intelligent surfaces, digital beamforming, spectrum sharing, and the Internet of Things.
“SoftBank Corp. is committed to driving innovation in 5G networks, including by adopting softwarization and relying on centralized radio access networks, to improve and guarantee customers’ experiences. We believe that Nvidia’s GPUs and Aerial SDK will play an instrumental role in this effort and we welcome the results of our joint collaboration - the world’s first - that show outstanding performance in running vRAN networks using Nvidia’s GPU. Integrating vRANs with edge computing and the AI ecosystem is key to delivering high performance 5G experiences and creating innovative solutions for the telco industry.”
Ryuji Wakikawa, Vice President and Head of Advanced Technology Division, SoftBank Corp.
“The telco industry is eagerly adopting cloud-native architecture to meet the growing compute demands of 5G. We are learning firsthand how the remarkable compute performance of NVIDIA GPUs, together with NVIDIA’s Aerial SDKs, can address the challenges of building flexible, high-performance virtualized telecom networks. We look forward to Aerial’s continued development.”
Yasuyuki Nakajima, president and CEO, KDDI Research, Inc.
“The collaboration between OAI and NVIDIA enables us to provide an end-to-end 5G radio network gNB stack that’s a powerful and flexible tool for wireless innovation. This platform comprises the OAI 5G Layer-2/Layer-3 (L2/L3) radio stack interfacing with the NVIDIA Aerial GPU- and NIC-accelerated Layer-1 (L1) to deliver an end-to-end gNB solution complete with a 7.2 split radio unit. This will deliver the power of NVIDIA L1 and flexibility of the OAI open-source L2/L3 stack, allowing for showcasing exciting new 5G and xG use cases and technologies that are central to such future-generation networks.”
