EXECUTIVE SUMMARY
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.
BUSINESS IMPACT - The Internet of Everything will be true not soon later. The IBN has great potential in the applications from users and devices in the park or branch office to the data center or cloud. It is able to reconfigure and optimize the network continuously, protect IT and business processes, and provide insight. The IBN simplifies the operation of opening and reconfiguring network service, as well as the operation of monitoring and assuring network quality after opening the service. Operators can use the IBN to capture the intents of business, and then monitor network status and implement strategies in the whole networks. It is able to satisfy the requirements of network business much better.
BUSINESS MARKETS - The Intents can be applied to multiple levels, such as application service levels, security policies, compliance transactions, operational processes and other business requirements. The IBN will be applied to the scenes of the opening and management of various network services. In the first stage, it will be used in the 5G use case to opening and monitoring of network services. Later, it will be integrated into more use cases to simplify the opening and management of services.
FUNDING/FINANCIAL IMPACTS - The IBN is able to respond to the requirements of organizations quickly with little human intervention. with the corresponding reduction of time and energy required for network maintenance, IT professionals can spend more time on innovation to bring practical value to the enterprise. The IBN is able to respond to the requirements of organizations quickly, simplify the manual operation of network opening and management, and reduce operators' OPEX.
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.
Scope for G release
Category | Requirement | Content | |
Architectural Requirements | AR1 | Support 5G slice creation by intent based network | Use intent based network to create 5G slice. |
AR2 | Support Intent instance LCM operations | provide functions for intent instance create, terminate, and KPI monitoring operations. | |
Functional Requirements | FR1 | User intent idendify | Use NLP module to parse user inputs, identify user intent and extract the key information. |
FR2 | Intent Translation | Translate high-level of abstraction to a more concrete form in order to be validated and processed. | |
FR3 | Intent Verification | Verify if the intent decision was executed as expected.(At present, there is no simulation verification, simple implementation, non-target solution) | |
FR4 | Intent Decision | Decide which, if any, policies shall be executed in response to a request by another managed entity for a set of governance actions. | |
FR5 | Intent Guarantee | Two-level closed loop and two-level monitoring |
