VIAVI Extends Capabilities of O-RAN Test Suite

TeraVM 5G virtualized testing solution now supports load testing of the Open Central Unit (O-CU) according to O-RAN specifications. This capability follows the March 2020 launch of the industry-first Test Suite for O-RAN Specifications, which is already being deployed by Tier-1 operators and network equipment manufacturers.

As mobile data traffic continues to grow, and the O-CU becomes the first point of data aggregation, its ability to manage high volumes of traffic is critical for operators to meet 5G service promises. According to O-RAN specifications, the gNodeB is disaggregated into three distinct and standardized elements: the Open Radio Unit (O-RU), Open Distributed Unit (O-DU) and O-CU from potentially different manufacturers, with the F1 interface defining interactions between the O-DU and O-CU. Service providers and equipment manufacturers will need to validate that components work together and meet 5G performance requirements, so interoperability testing needs to be an essential part of any test strategy.

TeraVM enables network equipment manufacturers and service providers to efficiently test mobile RAN and core elements, validating that the equipment works according to 3GPP standards, interoperates with other 5G elements, and performs optimally when fully loaded with complex mobile traffic profiles. TeraVM is part of VIAVI’s Lab to Field network testing and assurance portfolio as well as its Test Suite for O-RAN Specifications.
