Overview

The BBS-ep service is responsible for handling two types of events for the BBS use case.

The first type of event are PNF re-registration internal events that is published by PRH. The BBS-ep service processes the internal events to understand if they

actually constitute ONT(CPE) relocation events. In the relocation case, the BBS-ep service publishes an event towards unauthenticated.DCAE_CL_OUTPUT

DMaaP topic to trigger further Policy actions related to BBS use case.


The second type of event us the CPE authentication event originally published by the Edge SDN M&C component of BBS use case architecture.

Through the RestConf-Collector or VES-Collector, this event us consumed by the BBS-ep service and then forwarded towards unauthenticated.DCAE_CL_OUTPUT

DMaaP topic to trigger further Policy actions related to BBS use case.


The BBE-ep service periodically polls for the two events. The polling interval is configurable and can be changed dynamically from Consul. Its implementation

is based on Reactive Streams (Reactor library), so it is fully asynchronous and non-blocking.

Deployment Prerequisite/dependencies

The BBS-ep service requires DMaaP and A&AI to be functional in ONAP.

The BBS-ep service consumes/publishes messages from/to DMaaP and fetches (never updates) information from A&AI related to the BBS use-case logic.

Deployment Steps

To deploy

  • Transfer blueprint component file in DCAE bootstrap POD under /blueprints directory
  • Transfer blueprint component inputs file in DCAE bootstrap POD under / directory
  • Log-in to the DCAE bootstrap POD's main container

  • Validate blueprint

    Validate Blueprint
    cfy blueprints validate /blueprints/k8s-bbs-event-processor.yaml-template

  • Upload validated blueprint

    Upload validated blueprint
    cfy blueprints upload -b bbs-ep /blueprints/k8s-bbs-event-processor.yaml-template

  • Create Cloudify Deployment

    Create Cloudify deployment
    cfy deployments create -b bbs-ep -i /bbs-event-processor-input.yaml bbs-ep

  • Deploy component

    Deploy component
    cfy executions start -d bbs-ep install


To un-deploy

  • Uninstall running component and delete deployment

    Uninstall component
    cfy uninstall bbs-ep

  • Delete blueprint

    Delete blueprint
    cfy blueprints delete bbs-ep

Validation

After deployment, we can check if BBS-ep POD is running correctly

Verify BBS-ep is running
root@cluster-admin:~# kubectl -n onap get pods | grep -i bbs
dep-bbs-event-processor-6b6df75d94-g7jw8                          2/2       Running            0          1d


And then check the logs to see if it can connect to DMaaP, polling for events. Even in the absence of events, we can at least verify that there is nothing to consume for both PNF re-registration messages and CPE authentication messages.

Verify BBS-ep can poll DMaaP
kubectl -n onap logs dep-bbs-event-processor-6b6df75d94-g7jw8 -c bbs-event-processor
