VIAVI Provides Benchmarks and Verification Tests for Global O-RAN Plugfest

Increased interest in RIC testing shows the technology is maturing

VIAVI Solutions (VIAVI) (NASDAQ: VIAV) recently shared that the company participated in the 3rd Global O-RAN Plugfest hosted by Tier 1 Communication Service Providers and the O-RAN Alliance. This Plugfest will be held in 2021 A series of live demonstrations took place in several countries in October and November 2019.

VIAVI provided benchmarks and validations for Plugfest testing and demonstrations around the world, including: New Brunswick, USA, hosted by AT&T and Verizon in conjunction with Rutgers University; Menlo Park, USA, hosted by AT&T and Verizon in conjunction with Meta in TIP Community Experiment Berlin, Germany, hosted by Deutsche Telekom; Madrid, Spain, hosted by Telefónica; Gurgaon, India, hosted by Airtel; Tokyo, Japan, hosted by Yokosuka Research Park, Rakuten Major service providers such as Rakuten Mobile participated; Taiwan, hosted by Auray OTIC and Security Labs and Chunghwa Telecom.

This year’s Plugfest highlights the rapid development of the O-RAN ecosystem. As RAN Intelligent Controllers (RICs) gain more attention, artificial intelligence and big data are introduced into daily operations, and the way network resources are managed is also changing. To mitigate the risk of introducing such new technologies, operators rely on VIAVI tools, including TeraVM RIC tests, to test the performance of RICs in various RAN scenarios, as well as the capabilities of rApps and xApps, and provide the tools needed to generate and train AI models. way of data.

At the same time, VIAVI’s O-RAN standard test suite provides support for conformance, performance, interoperability and end-to-end testing:

Open Radio Unit (O-RU) and Open Distribution Unit (O-DU) – with VIAVI TM500 O-RU tester and Rohde & Schwarz SMW200A Vector Signal Generator (VSG) , FSW signal and spectrum analyzer, VSE vector signal analysis software validated Casa Systems Apex 5G Evo Radio. The performance of Sercomm small cell O-RU/O-DU is tested by VIAVI TeraVM O-CU simulator and TeraVM core simulator. For the O-RU test of Foxconn/WNC/Alpha/ITRI, the VIAVI TM500 O-RU tester was used.

Open Central Unit (O-CU) – Accelleran O-CU installed on a cloud-native router was tested for performance (load/scale) using the VIAVI TeraVM O-CU tester.

Open Fronthaul (OFH) – Validated Intel FlexRAN™ reference software with IP Infusion fronthaul switch as master clock and Capgemini Engineering O-CU, O-CU using VIAVI TM500 O-DU tester and E500 UE emulator OFH interoperability between DU and core. VIAVI also offers the T-BERD/MTS-5800 for Xhaul transmission and synchronization testing on the Grandmaster Ciena 5164 and 5168 and Cisco NCS540.

Foxconn O-RU was tested for end-to-end interoperability with another vendor’s O-DU and O-CU using VIAVI E500 UE emulator and TeraVM core emulator; TeraVM core emulator, Demonstration of OFH and end-to-end interoperability between Foxconn O-RU, Capgemini O-DU/O-CU and commercial equipment.

RIC – TeraVM RIC testing was used to validate Accelleran dRAX® RIC and xApps, as well as TCS RIC and Traffic Steering xApps. The TeraVM RIC test also supported demonstrations of the Rakuten Communication Platform (RCP), which enables self-healing and optimization of the RAN, including rApp impact compensation through RAN-optimized xApps running on the latest O-RAN SC RIC stack.

Sameh Yamany, CTO of VIAVI, said: “With each O-RAN Plugfest, we have seen a large number of vendors emerge and an increasing number of service providers commit to it, and there are clearer signs that the technology is Maturity. In 2021, the scope of investigation has expanded from connectivity between O-RAN elements to automated assurance and optimization using RIC and xApps.”

VIAVI provides the most comprehensive test platform on the market for laboratory validation, field deployment and service assurance of O-RAN networks, and can be deployed as Test-as-a-Service (TaaS) in on-premises, public or private clouds. With over 85% of Network Equipment Manufacturers (NEMs) adopting the VIAVI RANtoCore platform for gNB development, VIAVI can provide consistency, performance and interoperability for O-RU, O-CU, O-DU, RIC and core elements Provides unique and market-leading 5G and Open RAN test solutions.
