3. Component Description:

Usecase-UI  is a web application which contains two parts: 

  • Usecase-UI GUI
  • Usecase-UI Server

4. known system limitations

Now the component Redundancy and scaling depends on Kubernetes.

5. Used Models

Usecase-UI use the following models:

  • TOSCA  - VNF Descriptor/NS Descriptor  ETSI NFV SOL001  v2.4.1 & v2.5.1

6. System Deployment Architecture

Usecase-UI consists of 4 containers:

  • Usecase-UI-Operator Portal

  • Usecase-UI-Operator Server

  • Usecase-UI-Customer Portal
  • Usecase-UI-Customer Backend

7. New Release Capabilities

The Guilin Release supports two capabilities:   

  1. Transport  5G Slicing: Adding endpoint parameters to the Slicing Tasks portal to support transporting the An and Cn region
  2. E2E Network Slicing: KPI Monitoring: Supporting KPI data shown to users and also supporting standard API interface with EXT-API for KPI monitoring, and KPI data reporting to tenant/operator

And also, Guilin Release concludes a POC requirement:

  • Supporting an entry for IBN module to creating 5G Slicing service via the existing IBN individual system, as well as accepting the response data from IBN NLP module for creating CSMF Service.
