...

  • 2.0 The user clicks the button on UUI/Portal to deploy the CCVPN service, UUI/Portal will sent the deploy request to SO.
  • 2.1 SO talk with A&AI to create the new service instance in A&AI inventory
  • 2.2 SO decompose the CCVPN service template distributed by SDC.
  • 2.3 SO call SDNC to create CPE configure resource
  • 2.4 SDNC call A&AI to create CPE configure resource instance and attach this resource instance to the service instance.
  • 2.5 SO call SDNC to configure CPE
  • 2.6 SDNC call 3rd SDN controller to configure CPE.
  • 2.7 SO call VFC to create vCPE VNF
  • 2.8 VFC create the vCPE VNF instance in A&AI.
  • 2.9 SO call VFC to instantiate vCPE VNF
  • 2.10 VFC call 3rd VNFM to deploy the vCPE.
  • 2.11 SO call SDNC to create vCPE configure resource
  • 2.12 SDNC call A&AI to create vCPE configure resource instance and attach this resource instance to the service instance.
  • 2.13 SO call SDNC to configure the vCPE
  • 2.14 SDNC call the 3rd SDN controller to configure the vCPE.
  • 2.15 SO create the VPN network resource instance in A&AI and attach this resource instance to the service instance.
  • 2.16 SO query the network access points which CPE and vCPE connects to from the inventory OSS.  This access point are the terminal point of the topology in A&AI that notified by 3rd SDN controller(Refer to the flow 1).
  • 2.17 SO call OOF to calculate the route between the topology terminal points of CPE and vCPE.
  • 2.18 OOF query the whole topology information from A&AI.
  • 2.19 OOF calculate the route for the terminal points. And return a VPN list across multi topology.
  • 2.20 SO loop the VPNs to call SDNC to instantiate the VPN instance. 
  • 2.21 SDNC call 3rd SDN controller create vpn over the domain topology.
  • 2.22 SDNC add relationship between domain topology and  the VPN instance and return the VPN instance to SO.
  • 2.23 SO call A&AI to attach the VPN instance to VPN network resource instnace.

3. Service Design Flow

Image Added

  • 3.0 Design the service in SDC portal
  • 3.1 SDC distribute the service information to SO
  • 3.2 SDC distribute the service network information to SDNC
  • 3.3 SDC distribute the service model information to AAI
  • 3.4 SDC distribute the service VNF information to VFC/APPC.
