Use Case Overview & Description

(description of U/C)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.

Use Case Key Information

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 (Give a short description of your Use Case, the "Executive 2 min elevator pitch", this describes the "WHAT")

Business Impact - (This is the Business Impact which describes why this use case is important from a business perspective, this describes the "WHY").

Business Markets - (This is the marketing analysis, which can include but not limited to applicable markets, domains, marketing projections, this can describe the "WHERE").

Funding/Financial Impacts - (The Funding requirements and Financial impacts can describe the financial savings, or CAPEX, OPEX impacts for a Use Case)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 Markets - This 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 - (It is suggested that you use the following wording):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. (This would typically describe the "WHO", but because use cases are all deployed with ONAP itself, these two areas come with the actual ONAP deployment and uses the organizational management and sales strategies of a particular service provider's ONAP deployment)

USE CASE DIAGRAM

Use cases define how different users interact with a system under design.  Each use case represents an action that may be performed by a user (defined in UML as an Actor with a user persona).
