1. SO/OPENSTACK: CLOUD RESOURCE REQUEST – SO requests Openstack (Blazer) for a cloud resources request to OOF. OOF = NVF Orchestration. Does OOF do this? Is this not done? MEC instances.

2. OPENSTACK: ASSIGN CLOUD RESOURCES – Openstack Blazer assigns cloud resources based on the needs of the service. Assignments are balanced against NFV compute resources in each region, what is currently used/reserved and total capability. Compute resources availability to deploy a VM are consider. The NFV-Orchestration is defined in ETSI NFV.  SO can trigger a reservation request. NFV orchestration can create instances of different types. NFV orchestration has a policy. OpenStack Blazer, reservations localized to the cloud instance.

3. SO/OPENSTACK: CLOUD RESOURCE RESPONSE – Openstack responds with the allocated resources.

4. SO/SDN-C NETWORK ASSIGNMENTS – SO requests SDN-C to perform the Network Assignments needed by the Service instance. Can a Subnet, Network Port be assigned? (Virtual MAC, IP address), connect to VM. VM > create port > connect to VM.

5. SDN-C NETWORK ASSIGNMENTS – SDN-C performs Network Assignments needed by the Service instance.

6. SO/SDN-C NETWORK ASSIGNMENTS – SDN-C responds to SO with the Network Assignments needed by the Service instance and the status (success/fail).

7. SO/MCLOUD INSTANTIATION REQUEST – SO requests M-Cloud to perform the VNF instantiations needed by the Service instance.

8. MCLOUD INSTANTIATION REQUEST – MCloud performs VNF instantiations.

9. SO/MCLOUD INSTANTIATION RESPONSE – MCloud responds to SO with the VNF instantiations needed by the Service instance and the status (success/fail)

   
   
   

Continuation of SO Service Instantiation Flow:

1. ASSOCIATE RESOURCES WITH SERVICE – Ala 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.

   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.

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??)

3. CONTROLLER: ACTIVATE SERVICE – The controller (SDN-C, SDN-R, VF-C, APP-C) to activate the service.

4. CONTROLLER:

...

1. << what >> – Flow description accorCONFIGURE SERVICE – The controller configures the service, and configures the associated xNF resources.

2. 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.

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

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

5. SO/A&AI UPDATE RECORDS – SO updates the appropriate A&AI records with activation information. [What info is saved and in which records: Service vs VNF/PNF??]

6. USER NOTIFIED - SO notifies service initiator that the service is active.

4. Post Condition

The post-conditions are:
