Scenario Scope in Guilin

This scenario is for the "RAN sub-net slicing with ONAP interacting with an External RAN NSSMF" in REQ-342.

We add an External RAN NSSMF Simulator in integration project (INT-1707). The simulator is used to interact with ONAP SO NSSMF Adapter, and mainly supports the following operations:

• AllocateNssi
• DeallocateNssi

APIs of External RAN NSSMF Simulator

The following APIs of External RAN NSSMF Simulator reference 3GPP TS 28.531 V16.6.0.

AllocateNssi

Deployment Guide

1. Download:

2. Environment Setup (Optional):

1) The default listening port of RESTful API is 8443, and you can set environment variable RAN_NSSMF_REST_PORT to change it, such as:

2) The default username and password are in RanNssmfSimulator/etc/auth.json, and you can edit the file to change them or add new ones.

3. Install and Run:

There are two options to run the simulator:

Option 1. Directly run it in the current directory:

Option 2. Install it using setuptools, and run it in any directory:
