1 Introduction

This document provides information about troubleshooting Oracle Communications Cloud Native Core, Network Repository Function (NRF).

1.1 Overview

NRF is a key component of the 5G Service Based Architecture. NRF maintains an updated repository of all the Network Functions (NFs) available in the operator's network. It also maintains the services provided by each of the NFs in the 5G core that is expected to be instantiated, scaled, and terminated with minimal to no manual intervention. In addition to serving as a repository of the services, NRF also supports discovery mechanisms that allow NFs to discover each other and get the updated status of the desired NFs.

This guide provides extensive information about resolving problems you might experience while installing and configuring NRF. It also contains information about tools available to help you collect and analyze diagnostic data.

Note:

The performance and capacity of the NRF system may vary based on the call model, Feature or Interface configuration, and underlying CNE and hardware environment.
