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: 2
# of ONU Ports: 2
Total ONUs: (total: 4)

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

VOLTHA 2.X

This assumes voltctl is installed an configured

voltctl device create -t openolt -H bbsim-olt-id-0:50060
voltctl device enable $(voltctl device list --filter Type~openolt -q)

Control API

BBSim comes with a gRPC interface to control the internal state. This interface can be queried using bbsimctl (the tool can be build with make build):

$ ./bbsimctl --help
Usage:
  bbsimctl [OPTIONS] <config | olt | onus>

Global Options:
  -c, --config=FILE           Location of client config file [$BBSIMCTL_CONFIG]
  -s, --server=SERVER:PORT    IP/Host and port of XOS
  -d, --debug                 Enable debug mode

Help Options:
  -h, --help                  Show this help message

  config  generate bbsimctl configuration
  olt     OLT Commands
  onus    List ONU Devices

bbsimctl can be configured via a config file such as:

$ cat ~/.bbsim/config

server: 127.0.0.1:50070
grpc:
  timeout: 10s

Some example commands:

$ ./bbsimctl olt get
ID    SERIALNUMBER    OPERSTATE    INTERNALSTATE
0     BBSIM_OLT_0     up           enabled


$ ./bbsimctl olt pons

Know Issues

In some runs, EAPOL fails with:

time="2019-09-20T21:24:31Z" level=error msg="Can't send EapStart Message: ONU {intfid:1, onuid:2} - Not DONE (GemportID is not set)" IntfId=1 OnuId=2 OnuSn=BBSM00000102 module=EAPOL
time="2019-09-20T21:24:31Z" level=error msg="ONU failed to authenticate!" IntfId=1 OnuId=2 OnuSn=BBSM00000102 module=ONU

Investigate why this happens (we believe the source to be in the OMCI library)
