Usecase UI Istanbul Architecture Review

Project Overview

• Usecase-UI is an application portal which provides the ability to manage ONAP service instances. 

• Usecase-UI allows customers to create/delete/update service instances, as well as to monitor the alarm and performance of these instances. In Istanbul Release, Usecase UI will support kinds of service of intent management, such as creation, delete, deactivation and monitoring.

• Usecase-UI supports these use cases: CCVPN use case,  5G slicing use case and IBN use case.In Istanbul Release, UUI will bind E2E slicing users' intent-instance and business ID:

  • Usecase UI will receive the intent-instance message from SO while creating E2E service and send it to AAI to complete its binding with business ID

New component capabilities for Istanbul, i.e. the functional enhancements

Functional enhancements

1. IBN module:  Usecase UI will support kinds of service of intent management, such as creation, delete, deactivationvia adding a new “Intent-based Services” page

2. IBN module:  Usecase UI will support the monitoring of intent-instance via adding a new monirtoring page

3. E2E Slicing: Usecase UI will support the binding of intent-instance and slicing business ID

Platform enhancements

1. Improve platform maturity (TSC must have items)

   1. Remove GPLv3 from the dockers built by the ONAP community   USECASEUI-494 - usecase UI dockers contain GPLv3 开放

2.  Upgrade postgresql   USECASEUI-405 - 2 components in one Docker 处理中

3. PACKAGES UPGRADES IN DIRECT DEPENDENCIES USECASEUI-574: PACKAGES UPGRADES IN DIRECT DEPENDENCIES FOR ISTANBULClosed

4. Add test code for UUI USECASEUI-584: Add test code for uui-serverClosed

• Smart Intent Guarantee based on IBN - R9 Intent Instance

Platform Maturity Targets

• Remove GPLv3 from the dockers built by the ONAP community:  USECASEUI-494 - usecase UI dockers contain GPLv3 开放

• Organize the existed API, clarify the data format and parameter of them and delete the useless ones:  USECASEUI-506 - Organize the existed API 已关闭

• JDK upgrade evaluate and migrate (Depend on the commit resource) and Upgrade PostgreSQL: USECASEUI-405: 2 components in one DockerClosed

• PACKAGES UPGRADES IN DIRECT DEPENDENCIES upgrated USECASEUI-574: PACKAGES UPGRADES IN DIRECT DEPENDENCIES FOR ISTANBULClosed

• Test code coverage reach 55% USECASEUI-584: Add test code for uui-serverClosed

Listing of new or impacted models used by the project (for information only)

• Support for CCVPN/5G Slicing/IBN DM and align with the above data model in Istanbul release
