1 Introduction

This guide describes how to install or upgrade Oracle Communications Cloud Native Core, Service Communication Proxy (SCP) in a cloud native environment and Oracle Cloud Infrastructure (OCI). It also includes information on performing fault recovery for SCP.

Note:

  • This guide covers the installation instructions when Podman is the container platform with Helm as the Packaging Manager. For any other container platform, the operator must use the commands based on their deployed container runtime environment.

  • kubectl commands can vary based on the platform deployment. Replace kubectl with Kubernetes environment-specific command line tool to configure Kubernetes resources through kube-api server. The instructions provided in this document are as per the CNE version of kube-api server.

Caution:

User, computer and applications, and character encoding settings may cause an issue when copy-pasting commands or any content from PDF. PDF reader version also affects the copy-pasting functionality. It is recommended to verify the pasted content especially when the hyphens or any special characters are part of the copied content.

1.1 Overview

SCP is a decentralized solution composed of Service Proxy Controllers and Service Proxy Workers. It is deployed alongside 5G network functions and provides routing control, resiliency, and observability to the core network. For more information about SCP architecture and features, see Oracle Communications Cloud Native Core, Service Communication Proxy User Guide.

SCP can leverage the service mesh for internal and external communications. The service mesh integration provides inter-NF communication and allows coworking with service mesh. The service mesh integration supports the services by deploying a special sidecar proxy in the environment to intercept network communications between microservices. For information about installing SCP with Aspen Service Mesh (ASM), see Configuring SCP to Support Aspen Service Mesh.

Note:

The performance and capacity of the SCP system may vary based on the call model, feature or interface configuration, network conditions, and underlying CNE and hardware environment.
