After the ONAP brought in, users can forward client service via a unified customer self-service portal. ONAP orchestrator will send out channel built request to SOTN Controller after checking the service request and OTN resource state. Then a private channel is built. Domain controller will finish resource configuration on the basis of ONAP request.
For The CCVPN use case , we design 4 services: SOTN VPN Infra Service, SD-WAN VPN Infra Service, Site DC Service , Site Enterprise Service.
One CCVPN scenario, can contains one SOTN VPN Infra Service, more than one SD-WAN VPN Infra Services, more than one Site DC Services, more than one Site Enterprise Services. And Each SD-WAN VPN Infra Service can attach more than one site.
- Topology Notification flow
1.0 3rd SDN controller notify the single domain topology to SDNC.
1.1 SDNC analyse the data from 3rd SDN controller. Get the nodes, links, terminal points of the topology.
1.2 SDNC call A&AI to create the nodes, links terminal points to save the topology.
Note: For multi 3rd SDN controllers, there will be several topologies notified. The links across the domain topology should be discovered or created by ONAP. - Vpn Infra Service Deploy Flow
