The TeraVM is a family of products that enables network equipment manufacturers and service providers to efficiently test mobile RAN and Core Network elements at scale, with its fully virtualized architecture TeraVM runs on x86 Commercial Off The Shelf (COTS) hardware or in the cloud, providing a repeatable and consistent test environment, available without the need for engineers to enter the test lab.

The most recent addition to this family of products is the first-to-market TeraVM O-CU Tester,  this O-CU subsystem test solution delivers a complete wraparound testing framework for the O-CU with TeraVM’s stateful emulation capabilities, ensuring that the O-CU can be robustly tested and optimized for high-quality and performance in a deterministic, repeatable and reproducible manner.TeraVM supports negative test cases as standard

TeraVM O-CU Tester for O-CU subsystem test can emulate:

• Over the F1 interfaces - network topology and slice aware UE sessions and the O-DUs testing the O-CU (device under test) with stateful 3GPP and O-RAN compliant F1-C and F1-U sessions and procedures

• Over the X2 (NSA EN-DC) and Xn (SA) interfaces – eNB and gNBs testing the O-CU (DUT) with stateful 3GPP compliant X2-C/U and Xn-C/U sessions and procedures

• Over the S1 (NSA EN-DC) and NG (SA) interfaces – EPC (EN-DC capable) and 5G SBA Core with stateful 3GPP compliant S1-MME/S1-U and NG-C/U sessions and procedures

• Complex application traffic flows emulation traversing over the established 4G core PDN sessions and 5G Core network slices and PDU sessions

TeraVM O-CU Tester for O-CU subsystem test validates that the O-CU works:

1. According to 3GPP standards and O-RAN C-plane and U-plane profiles

2. Interoperates with other 5G and O-RAN network functions and components

3. Performs optimally when fully loaded with complex mobile traffic profiles

TeraVM O-CU Tester performs these tests by emulating many O-DUs and UEs to generate 5G control plane and/or user plane traffic to test the O-CU.  The ability to emulate high data rates and large numbers of O-DUs is vital as the O-CU is the first data aggregation point between the RAN and the Core.
