DESCRIPTION

The Intent-based Network (IBN) is available to bridge the gap between the business department and IT department. It is able to capture the intents of business sensitively, and then reconfigure the end-to-end network according to the intents momentarily. Normally, the operation of underlay network and related systems are involved when opening or reconfiguring a network service. It needs professionals of different roles to perform a series of complex operations, which also takes a long time. The target of IBN is to establish an extensible framework to identify the users' network requirements based on natural language, allocate appropriate resources with the help of preset business knowledge or self-learning intelligent engine, and then convert them into the operations of network equipment and interface automatically, so as to simplify the operations.

In addition, the IBN also includes:

(1) Intent verification function: It is used to verify whether the automatically created network services satisfy the requirements of users;

(2) Intent assurance function: With the help of periodic analyzed business KPI, it checks whether the current network services satisfy the users' requirements, such as QoS. If not, it will reconfigure the resources and networks to satisfy the expectations of users.
