1 Introduction

This document provides information about the role of Oracle Communications Network Analytics Data Director (OCNADD) in the Network Analytics suite of products and how to configure and use OCNADD services and managed objects.

Overview

OCNADD is an specialized Network Data Broker (NDB) in 5G Network Architecture.

OCNADD receives the network traffic data from various sources, 5G network functions (NFs), Non-5G NFs, or third-party producers. It performs replication and aggregation on the received data according to the rules implemented by the subscribed third-party consumers. OCNADD sends the replicated and aggregated data to the subscribed third-party consumer applications or platforms in a secured manner.

OCNADD ensures data security, low latency, and redundancy while collecting and processing the data. It enables Communication Service Providers (CSPs) to correlate and transform the acquired data as per their data feed configuration to create comprehensive dashboards and Key Performance Indicators (KPIs) thereby achieving meaningful insights about all functions in 5G Network Architecture. This information can be used for monetising, providing good quality of service, reducing downtime, easing network scalability, and minimizing losses. The OCNADD generated data can be beneficial for monitoring and troubleshooting issues during a network failure.

The following diagram provides the high-level overview of OCNADD functionality:

Functional Architecture

OCNADD performs the following key functions:

  • Data aggregation: Collects and aggregates network traffic data from multiple NFs, such as SCP, SEPP, and NRF. The NFs can be available at a single site or different sites. OCNADD routes the consolidated traffic data to third-party consumer applications or monitoring tools that have subscribed to receive the traffic data.
  • Data replication: Routes the consolidated data to multiple third-party consumer applications that use the data for monitoring, troubleshooting, or security purpose. Multiple data feeds are received based on the filtering configurations specified by the third-party consumer applications. OCNADD replicates these feeds to more than one third-party consumer application. It also provides the feed to multiple third-party systems, such as monitoring, troubleshooting, and security tools with the collected data.

    Note:

    OCNADD supports the replication for maximum five third-party consumer applications.
  • Secure data transport (TLS): Provides a secure data communication between producer NFs and 3rd-party consumer applications. The incoming data streaming towards OCNADD and outgoing data streaming towards 3rd-party applications are TLS encrypted.
  • Operational dashboard: Provides a dashboard with different visualization operations and a panel for configuring metrics, KPIs, and monitoring alarms to track the system health.
  • Data governance: Supports data governance by managing the availability, usability, integrity, and security of data in the enterprise systems based on Oracle data standards and policies that control data usage.
  • Health monitoring: Supports a health monitoring functionality that to monitor the readiness and liveness of each of the microservice instances. The health monitoring feature also provides each OCNADD service's health report, which can be monitored on demand or periodically using the OCNADD dashboard.
  • Backup and restore: Provides a backup and restore functionality to enable high availability and quick recovery from any failures. The configuration backup is taken periodically from already deployed setup, so that if a cluster fails, it can be restored quickly.
  • High availability: The OCNADD instance is deployed in pods in the Kubernetes clusters that ensures high availability of the services, and in case of a failure, new instance of the services is available immediately. In case of a Kubernetes cluster failure, the OCNADD deployment is restored to a different cluster.
