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:

cd deployments/helm-chart
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: 1
# of ONU Ports: 1
Total ONUs: (total: 1)

OLT is listening on: "voltha.svc.bbsim-olt-id-0:50060"

VOLTHA 1.X

Connect to the voltha CLI and execute this commands:

preprovision_olt -t openolt -H voltha.svc.bbsim-olt-id-0:50060
enable

Control API

BBSim comes with a gRPC interface to control the internal state. We plan to provide a bbsimctl at certain point, meanwhile you can use grpcurl:

$ export BBSIM_IP="$(kubectl get svc -n voltha bbsim-olt-id-0 -o go-template='{{.spec.clusterIP}}')"
$ grpcurl -plaintext $BBSIM_IP:50070 bbsim.BBSim/Version
{
  "version": "0.0.1-alpha",
  "buildTime": "”2019.08.09.084157”",
  "commitHash": "9ef7241b07a83c326ef152320428f204f7eff43d"
}


$ grpcurl -plaintext $BBSIM_IP:50070 bbsim.BBSim/GetOlt
{
  "ID": 22,
  "OperState": "up",
  "NNIPorts": [
    {
      "OperState": "down"
    }
  ],
  "PONPorts": [
    {
      "OperState": "down"
    }
  ]
}

Development

To use a patched version of the omci-sim library:

make dep
cd vendor/github.com/opencord/
rm -rf omci-sim/
git clone https://gerrit.opencord.org/omci-sim
cd omci-sim

Once done, go to gerrit.opencord.org and locate the patch you want to get. Click on the download URL and copy the Checkout command.

It should look something like:

git fetch ssh://teone@gerrit.opencord.org:29418/omci-sim refs/changes/67/15067/1 && git checkout FETCH_HEAD

Then just execute that command in the omci-sim folder inside the vendored dependencies.
