General Intent Model and General Intent Interface Proposal:
Intent Analysis Server Architecture Proposal:
The Use Case Description:
Intent Analysis
Background：
A video business Enterprise have local site and cloud site, so they need a CLL VPN to support their daily office from local site to cloud site. And some times they will trans a lot of videos from local to the cloud , they hope the service provider can support this high-flow transfer to ensure their office work.
...
The service assurance sub intent will be translate to the closed-loop call . Intent analysis server will call DCAE(through configuration policy) to create the monitor logic for the CLL service and also call Policy to create the policy rules.( The logic will be based on the CCVPN-IBN use case.)
Impact projects:
| Project | Impact Description | Remark |
|---|---|---|
| UUI-Portal | UUI Portal should support the Intent management page. | |
| UUI-Intent Analysis Server | 1.Provide the function of decomposition and orchestration of intent. 2. Support general intent model and general intent interface 3. Support translate intent by APEX policy 4. Support CLL use case.Create CCVPN instance through SO, create Policy and DCAE rules for assurance. | |
| DCAE | 1.Provide the solution for intent analysis service to create/delete the monitor rule for the CLL usecase. 2.Should do enhancement on the old CCVPN closed loop, so that that can support both increase and decrease the bandwith. | |
| Policy | 1.Provide the corresponding policies for intent decomposition and intent maaping 2. Provide the APIs to create/delete policy for CLL usecase. 3. Support to listen the event of DCAE and take the action for increase and decrease the bandwith. 4.Suport th APEX policies neede by intent analysis server(Orchestration, Decomposition, Mapping ,Decision to select the 3rd party intent management etc.) | Bandwith increase is supported by CCVPN-IBN in Jakarta release, recover the bandwith should be support in Kohn release. |
| SO | SO support the CLL instance creation APIs to the intent analysis server | The feature is supported in Jakarta release , need integration test. |

Note:
- The closed loop policy is Drools policy , to make sure the Policy module to take increase/decrease bandwidth action when get the DCAE enent.
- The configuration policy will sent the runtime DCAE analyse service micro-service configuration , this configuration will control the micro service will monitor the CLL service or not.These two calls make sure the closed loop created or removed for the CLL service ，to support the high-flow support intent.
