Smart Intent Guarantee based on IBN - R9 Intent Instance



Use Case Overview & Description

The new network applications, like E2E Slicing and CCVPN, provide different SLA services to customers. In this REQ, a scenario of intent guarantee is proposed to support the SLA requirements of users in run-time, as well as updating users’ intents. In R9, Intent instance will be developed to support the E2E Slicing and CCVPN.

BUSINESS DRIVER

This section describes Business Drivers needs. These business drivers are presented on the Requirements Sub-committee and should also be put into the release requirements sub-committee page.

Executive Summary - Intent-based network (IBN) is a self-driving network that uses decoupling network control logic and closed-loop orchestration techniques to automate application intents. An IBN is an intelligent network, which can automatically convert, verify, deploy, configure, and optimize itself to achieve target network state according to the intent of the operators, and can automatically solve abnormal events to ensure the network reliability. In R9, a scenario of intent guarantee is proposed, and the development of Intent instance will be done to support the use cases of both E2E Slicing and CCVPN.

Business Impact - It is a challenging problem to guarantee the users’ intents in run-time. The REQ of intent-based network provides a scenario of users’ intent guarantee and interacting.

Business MarketsThis REQ provides a novel solution to support the SLA service.

  1. A users’ intent instance is proposed to monitor and analysis the network in run-time to satisfy the users’ SLA service.

  2. The users’ intents are updated in run-time based on the network situation and the interaction with users.

Funding/Financial Impacts - This function will provide more SLA services to increase the income of operators based on the current networks with few investments.

Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.
