From an Operator's perspective, it is important to introduce the capability to manage the performance of the CCVPN End-to-End service (especially when it spans across different Operators). The ultimate goal of this use case is, by taking advantage of the strong orchestration ability of ONAP, to automatically create and deploy a cross operator, cross domain (SOTN + SD-WAN), cross layer (L1, L2, L3) end to end VPN and update the service dynamically.
Main functions in this use case include automatically design of end to end service, creation of end to end service, cross-domain resource cooperation, global rerouting.
We testified this possibility in C release and realized functions like topology discovery, simple service creation, as well as back-up link switch in closed loop.
Planning for Dublin (Not fully provided in Dublin Release, will be continued in Frankfurt Release)
In Casablanca, the basic CCVPN usecase demonstrated ONAP's capability in designing and creating an end-to-end VPN service across operator domains.
...
In Dublin, CCVPN assumes the SP provides two types of service componts functions to its enterprise customer for selection, including:
...
Service Procurement (SP)
The enterprise HQ may want to order a VPN stretch between two or more branch sites, they may also want other value added services bind with the VPN service. A customer facing portal is provided under this condition so that a customer can choose which sites to set the VPN service and combine what kind of value added service with the VPN service, as well as provide other customized needs of the service like the bindwidth and duration without knowing the deployment details and VPN parameters. We call this process as service procurement and a service order is placed at this phase.Service Instantiation (SI)
After the service order is obtained, another page will pop out for users to finish other detailed inputs of CCVPN parameters so that a CCVPN service can be instantiated and deployed by ONAP.Service Change (SC)
Besides setting up a VPN service between multiple sites, customer may also have the needs to add other sites or add a new value-aadded service onto the existing VPN service according to their demands.SC1: Adding a new site
Customer chooses "Change Service" button in customer portal, and selects the sites to be added. After the order change is finished, the changed order will be passed to user portal to inform the user. Then, users will modify the sites information as well as other service input parameters and command ONAP to do the service change.SC2: Adding a new value-added service
Customer chooses "Change Service" button in customer portal, and selects the value-added service to be added. After the order change is finished, the changed order will be passed to user portal to inform the user. Then, user will add related parameters and command ONAP to do the service change.
Close Loop Intelligent Suveillance (IS)
After user subscribes the AI apps, AI apps on the edge can analysis data collected by camera or other security detector. Once there is an alarm, the original alarm data will be transferred to Ves Collector and DMaaP will translate the data, Holmes will send the event to Policy to trigger the responding action to adjust the bandwidth in close loop.
Gap Anaysis and Functional Requirements
...
High Priority Extensions (enhancements) in Dublin release:
Multi-site to multi-site Service
...
Creation
In an ideal implementation, the Portal shall create a single Service Order via TMF 641, with multiple service orderItem(s) for each of the services that make up the CCVPN Service.
- SDC should support create an E2E service with one service template by supporting inputs of multiple resources at the same time (instead of using multiple service templates one by one when creating an E2E service) and SO should have the capability to decompose and (eventually) delegate the nested Services.
- A&AI should maintain composite End-to-End Service Instance for CCVPN.
- Parameters for all services can be passed as one composite orderItem to External API.
Service Change : Add or Delete a site
...
A CCVPN End-to-End Service Change (e.g., bandwidth change), should be either triggered by the portal (as TMF 641 single service orderItem with ACTION ‘change’) or by a policy implemented to guarantee that SLS is met.
