BBS (Broadband Service)
-----------------------
Overview
~~~~~~~~
The BBS use case proposes using ONAP for the design, provisioning, life-cycle
management and assurance of broadband services. BBS focuses on multi-Gigabit
Internet Connectivity services based on PON (Passive Optical Network) access
technology.
In Frankfurt release, BBS enables ONAP to
1. Establish a subscriber's HSIA (High Speed Internet Access) service from an ONT (Optical Network Termination unit) to the Internet drain
- The HSIA service is designed and deployed using ONAP's design and deployment capabilities
- The HSIA service activation is initiated via ONAP's External APIs and orchestrated and controlled using ONAP orchestration and control capabilities. The control capabilities leverage a 3rd party controller to implement the requested actions within the technology domain/location represented by the domain specific SDN management and control function.
2. Detect the change of location for ONT devices (Nomadic ONT devices)
- PNF (Re-)Registration for an ONT
- Subscriber association to an ONT via ONAP's External APIs
- ONT association with a expected Access UNI (PON port) when a HSIA service is created/deployed for a subscriber
- PNF (Re-)Registration using ONAP's PNF registration capabilities
- Service location modification that is detected by ONAP's analytic and initiated via the closed loop capabilities
- The closed loop capabilities invoke a HSIA location change service that
is orchestrated and controlled using ONAP capabilities and 3rd party controllers

System View
~~~~~~~~~~~
BBS relies on key ONAP components such as External API, SO, AAI, SDC, Policy
(APEX engine), DCAE (PRH, BBS Event Processor, VES collector, VES mapper,
RESTCONF collector) and SDNC

System Set Up and configuration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SO: Custom Workflow Configuration
=================================
::
~/oom/kubernetes# kubectl edit cm dev-so-bpmn-infra-app-configmap
## replace "workflow:\n CreateGenericVNFV1:\n"
## with "workflow:\n custom:\n BBS_E2E_Service:\n sdnc:\n need: true\n CreateGenericVNFV1:\n"
## Restart the pod
~/oom/kubernetes# kubectl delete po dev-so-so-bpmn-infra-7556d7f6bc-8fthk
As shown below, new entries need to be inserted manually in SO database (mariadb-galera) in order to map a given resource model to a specific BPMN recipe. For instance, the CPE is modeled in SDC as a VF but it is treated as PNF resource by SO by using the handlePNF BPMN recipe. Those entries need to be inserted in catalogdb database > vnf_recipe table.
IMPORTANT: make sure vnf_recipe.NF_ROLE matches vnf_resource.MODEL_NAME, and vnf_recipe.VERSION_STR matches vnf_resource.MODEL_VERSION.
::
root@onap-rancher-daily:/home/ubuntu# kubectl exec -ti dev-mariadb-galera-0 sh
sh-4.2$ mysql -u root -p
