Comprehensive portfolio used to verify conformance, interoperability, performance, security and demonstrated innovative proof of concepts such as energy savings and AI/ML assisted optimization
SANTA ROSA, Calif. June 30, 2022
Keysight Technologies, Inc. (NYSE: KEYS), a leading technology company that delivers advanced design and validation solutions to help accelerate innovation to connect and secure the world, participated in the fourth global PlugFest event organized by the O-RAN ALLIANCE , accelerating development of Open RAN (O-RAN) technologies with open standard interfaces, intelligence and security.
Keysight Open RAN Architect (KORA) solution portfolio enabled 15 vendors, 4 mobile operators and 2 Open Testing and Integration Centers (OTIC) at 3 PlugFest venues and 5 labs across Asia, Europe and North America to verify integration of multi-vendor network functions and compliance to O-RAN specifications.
Keysight collaborated with leading vendors and mobile operators on industry first demonstrations in key areas of innovation including:
- Evaluation and assessment of energy savings features using live networks traffic profiles which have shown significant reduction in energy consumption for a multi-vendors cloud-native O-RAN system.
- Enablement of RAN Intelligent Controller (RIC) assisted artificial intelligence / machine learning (AI/ML) optimization for energy savings and admission control use cases, as well as an orchestration framework that supports rapid deployment of test and validation for near-real time RICs and xApps.
- Pre-certification testing of the O-RAN Radio Unit (O-RU), automated security testing for DevSecOps with 3GPP Security Assurance Specification (SCAS) test cases, Denial of Service (DoS) and fuzzing attacks simulations and performance testing of O-RAN Xhaul transport network elements' fronthaul implementation under real-world conditions.
"Keysight is pleased to collaborate with partners in the fourth O-RAN Global PlugFest during which we have successfully completed several industry-first demonstrations in key areas including energy savings, RIC-enabled AI/ML based optimization, test automation framework for RICs and applications, pre-certification testing, DevSecOps security with attacks simulation and transport network elements performance testing," said Giampaolo Tardioli, vice president and general manager of Keysight's Network and Operators group.
Fourteen Keysight solutions were used to make progress in the development of technical and test specifications for open standard interfaces, Xhaul transportation, O-Cloud, RIC, and AI/ML that enabled use cases and O-RAN security requirements.
