  1. ASSOCIATE RESOURCES WITH SERVICE – A la carte Create resource. Macro W/F needs service instance ID associate resource w/ Service Instance. When instantiate PNF service (PNF name) subscribe ID. Update instance in A&AI. Create a relation object where service instance ID & PNF instance ID. Relation modeled service instance + resources. Resource and can see which services it is used. VNFs create service have UUID of service instance. At creation of VNF create the Instance object.

    https://wiki.onap.org/display/DW/VNF+and+PNF+Building+Block+Strategy

    CPE, BBS, starts when you startup the PNF. Cloud environment creates a VNF. Registered/discovered PNF, build a homing service PNF. How will this work w/ 5G RAN. BBS U/C, registering the Box, customer starting up the box. Waiting for registration event. When receive the registration configure the network, additionalfield has domain-specific information to calculate best configuration of network to configure the PNF. After homing, SO creates a resource level sub-flow w/ a globally unique UUID in A&AI. In that that in sub-flow there is a correlation done with VES. The configuration that takes place happen in the resource level sub-flows. Svc instantion, correlation ID in A&AI. VES w/ correlation ID SO does the correlation (Plug n Plug)

  2. SO/CONTROLLER: ACTIVATE SERVICE REQUEST – SO requests the controller (SDN-C, SDN-R, VF-C, APP-C) to activate the service. (Where does SO get data to configure a service??). SO determines the order in which to instantiate the xNF resources. Right now SO does networks first then VNFs. Eventually this should be model-driven from TOSCA. Heirarchical resource creation & nested services.

  3. CONTROLLER: ACTIVATE SERVICExNF – The controller (SDN-C, SDN-R, VF-C, APP-C) to activate the xNF resources associated with the service.

  4. 4a CONTROLLER: CONFIGURE SERVICExNF – The controller configures the service, and configures the associated xNF resources associated with the service.

  5. 4b A&AI Published to DMaaP - A&AI publishes on DMaaP that a new service is active, How does it know? A change in status? #1 when dealing with VNFs, the contents of A&AI created when doing something in VID. Create a VNF in a service. Record in A&AI is created immediately. (no VMs are deployed). Same for VF modules. Get back info from OpenStack, HEAT. States are then updated. #2 BBS event CPEauthenticated. BBS & Service, send registration w/ SO & Controller configure networking. Sending CPE authenticated (event means running, active, successfully configured). Go to service instance mark it as “activated”. Confirm end-user can use the services. W/F specific to services. Refer to generic building blocks. TOSCA Modeling of nodes. TOSCA orchestrator has plug-ins for clouds. Cloud specific parameters, unable to create a node in AWS/Azure. A&AI can be configured to “announce” a state change of a service.

  6. 4c DCAE LISTENING - DCAE is listening for a new service notifications and starts to monitor the service.

  7. SO/CONTROLLER: ACTIVATE SERVICE RESPONSE – The controller responds with the Service configuration, and responds to the activation service request back to SO.

  8. SO/A&AI UPDATE RECORDS – SO updates the appropriate A&AI records with activation information.

  9. USER NOTIFIED - SO notifies service initiator that the service is active. In this example flow, it would be the user at the VID who gets informed that the Service is available and active.
