O-RAN ALLIANCE advances testing and integration

The O-RAN Global PlugFest Fall 2022 was successfully completed in 6 venues across Asia, Europe, and North America, with 106 participating companies.

O-RAN ALLIANCE global PlugFests represent a major platform enabling efficient progress of the O-RAN ecosystem through well-organized testing and integration. O-RAN Global PlugFest Fall 2022 is the second O-RAN PlugFest this year. In combination with the Spring PlugFest, the 2022 O-RAN Global PlugFests span across 9 venues with 156 participants, of which many participated at more than one venue.

“Testing and integration at O-RAN PlugFests show increasing maturity of O-RAN technology in all regions,” said Linsheng Liao, O-RAN TIFG Co-chair and Senior Project Manager of CMRI. “Comparing the PlugFest results year to year, we are pleased to see major progress made by the O-RAN ecosystem in conformance and interoperability tests, as well as more advanced end-to-end and network automation scenarios. O-RAN PlugFests greatly contribute to developing commercially available O-RAN networks.”

O-RAN Global PlugFest Fall 2022 in Europe
Deutsche Telekom, EANTC, EURECOM, Orange, TIM, Vodafone and BT have teamed up together with Telecom Infra Project (TIP) to host the Joint European O-RAN & TIP PlugFest Fall 2022. The PlugFest was hosted in four European labs, namely EURECOM in Sophia Antipolis, i14y Lab in Berlin, Orange Lab in Paris and TIM Innovation Lab in Torino.

The joint PlugFest has demonstrated complementarities and synergies between O-RAN and TIP as well as between the labs.

Test scenarios focused on:

  • Conformance testing of Open Fronthaul interface of O-RU and O-DU
  • End-to-end multi-vendor integration with functional and performance testing
  • xApps/rApps integration with Near/Non-RT RICs and xApps/rApps functional verification
  • O-Cloud platform performance testing

In addition to the hosts, participants included Aarna Networks, Accelleran, ADVA Optical Networking, Analog Devices, Anritsu, Aspire Technology, Azcom Technology, Calnex Solutions, Capgemini Engineering, Dell Technologies, DZS, Fujitsu, Hewlett Packard Enterprise, highstreet technologies, JMA Wireless, Juniper Networks, Keysight Technologies, Mavenir, Microamp Solutions, MTI, NEC, Net AI, Nokia, Open Networking Foundation, Radisys, Red Hat, Rimedo Labs, Rohde & Schwarz, SIAE MICROELETTRONICA, SOLiD, Spirent, VIAVI Solutions, VMware and VoerEir.

O-RAN Global PlugFest Fall 2022 in North America
PlugFest in North America hosted by CableLabs at the Kyrio OTIC Lab focused on:

  • Multi-vendor O-RAN end-to-end system under test, based on the O-RAN E2E test specification, demonstrating cell capacity for signaling and user-plane traffic load. Moreover, the Fronthaul delay impact on user peak throughput was measured using Fronthaul impairment emulators.
  • Demonstration of O-CU interoperability, based on the O-RAN IOT test specifications, verified traffic scenarios across emulated F1 and
  • Xn interfaces, as well as the open F1 and Xn protocol implementation. In addition, the O-CU demonstrated successful interoperability for F1AP and XnAP global, elementary, and mobility procedures.
  • Near-RT RIC testing for conformance to the O-RAN E2 interface specification (E2AP, E2 SM, E2 SM RC, and E2 SM KPM procedures) were verified following the E2 test specification. Moreover, a QoS xApp was integrated and tested.

In addition to the hosts, participants included Calnex Solutions, Capgemini Engineering, Lumentum Holdings, Radisys Networks, Sunwave Communications, VIAVI Solutions and Xena Networks.

PocFest in North America hosted by UNH-IOL, hosted by AT&T and DISH, took place in four labs:

  • University of New Hampshire InterOperability Lab
  • TIP Community Lab at Meta, Menlo Park CA
  • POWDER Lab and NSF PAWR SITE with the University of Utah
  • COSMOS Lab and NSF PAWR SITE with the Rutgers University, Columbia University, NYU Wireless

Activities focused on testing of conformance and performance of O-RU devices, measurements of energy saving and efficiency, integration of AI/ML for resource pooling and slicing, testing of RIC, xApps, SMO, and end-to-end interoperability testing.

In addition to the hosts, participants included AMD, Anritsu, Calnex, DZS, Fujitsu, HCL, Intel, Keysight Technologies, NEC, Radisys, Rohde & Schwarz, VIAVI Solutions, VVDN, VMware, Vodafone, Wind River and Xena.
