BroadBand Simular (BBSim)

Build

BBSim is managed via a Makefile, plese run the following command to display all the available targets

make help

Usage

Deploy on Kubernets

Once VOLTHA is deployed you can deploy BBsim using the helm chart provided in the repo:

git clone https://github.com/opencord/helm-charts.git
helm install -n bbsim bbsim

OLT Provisioning

Once BBSim is up and running you can provision the OLT in VOLTHA.

When you install the BBSim helm chart you'll notice that the last line of the output prints the service name and port:

...
NOTES:
BBSim deployed with release name: bbsim

OLT ID: 0
# of NNI Ports: 1
# of PON Ports: 2
# of ONU Ports: 2
Total ONUs: (total: 4)

OLT is listening on: "voltha.svc.bbsim:50060"

VOLTHA 1.X

Connect to the voltha CLI and execute this commands:

preprovision_olt -t openolt -H voltha.svc.bbsim:50060
enable

VOLTHA 2.X

This assumes voltctl is installed an configured

voltctl device create -t openolt -H bbsim:50060
voltctl device enable $(voltctl device list --filter Type~openolt -q)
