TeraVM 5G SA Core Test for TVM-vRAN
UPF Wraparound Test

Overview
The VIAVI TeraVM UPF wraparound feature provides aFeaturescomprehensive validation test suite for the User Plane Function

 First to market UPF wraparoundtest, compliant with Latest 3GPPstandards(UPF).
The UPF is the interconnect point between the UE and the Data
Network responsible for encapsulating and decapsulating GPRS

 Runs in lightweight VM on standard
x86 hardware

Tunneling Protocol for the user plane.

 CI/CD Automation Integration

UPF represents the Data plane of a CUPS (control and user plane Supports Open source automation
tools such as Jenkinsseparation) strategy allowing packet processing and traffic
aggregation to be performed closer to the network edge.

 Functional Testing Performance, Capacity Testing

UPF is the pressure point for user plane traffic and requires robust
testing in a variety of traffic application profiles and handovermobility scenarios.
The UPF is completely controlled from the SMF using the N4
interface. The SMF uses the Packet Flow Control Protocol (PFCP) todefine how the packets are identified, forwarded, processed, marked
and reported by the UPF.

UPF Wraparound Testing
One of the biggest time-to-market challenges facing NEMs
and mobile operators as they launch 5G services is developing
products against constantly changing and maturing 3GPP specs.
Consequently, as UPF functions are developed, the major obstacle
to developers is readily available 5G compatible network elements
to fully test the node. Not only are other elements of the 5G
standalone Core network required (SMF) but a compatible 5GRadio Access network is required to test the N3 interfaces and a
Data Network/Internet Emulator to test the N6 interface.

 NFV MANO Ready Lab to Field – Same test tools used inthe fieldTeraVM vRAN 5G Emulator emulates 5G gNBs according to the latest 3GPP Rel 15 specs while TeraVM 5G Core
Emulator emulates all functions of the 5G Standalone Core Network allowing the interfaces to the UPF be exposed
and the UPF under test be bracket tested.

Emulated RAN

Automation and Scripting
The TeraVM UPF wraparound tester comes with build-in management options, shell or a web client and provides
APIs to control and operate the tester from external applications.
UPF- wraparound shell:
 CLI (Command Line Interface) with readline/autocompletion support
 Fully scriptable
