-# BBR
-
-BBR (a.k.a BBSim Reflector) is a tool designed to scale test BBSim.
-It is responsible to emulate ONOS and VOLTHA in order to quickly reply
-to any message that BBSim sends.
-
-Here is a graph of the measuraments of BBSim performance captured over
-10 runs with different PON Layout
-
-
-
-
-## Run BBR
-
-To run `bbr` you need to have a `bbsim` instance running.
-
-You can start `bbsim` locally with:
-
-```bash
-$ DOCKER_RUN_ARGS="-onu 16 -pon 4" make docker-run
-```
-
-Once `bbsim` is up and running you'll see this on the console:
-
-```bash
-docker run -p 50070:50070 -p 50060:50060 --privileged --rm --name bbsim """"bbsim:0.0.2-dev /app/bbsim -onu 16 -pon 4
-time="2019-10-18T00:24:46Z" level=info msg="BroadBand Simulator is on" NumNniPerOlt=1 NumOnuPerPon=16 NumPonPerOlt=4 OltID=0
-time="2019-10-18T00:24:46Z" level=debug msg=CreateOLT ID=0 NumNni=1 NumOnuPerPon=16 NumPon=4 module=OLT
-time="2019-10-18T00:24:46Z" level=info msg="Successfully activated DHCP Server" module=NNI
-time="2019-10-18T00:24:46Z" level=debug msg="Created OLT with id: 0"
-time="2019-10-18T00:24:46Z" level=debug msg="Started APIService"
-time="2019-10-18T00:24:46Z" level=debug msg="APIServer Listening on: 0.0.0.0:50070"
-time="2019-10-18T00:24:46Z" level=debug msg="OLT Listening on: 0.0.0.0:50060" module=OLT
-```
-
-At this point you can start `bbr` (note that you need to pass the same number of ONUs and PON Ports to the two processes):
-
-```bash
-$ ./bbr -onu 16 -pon 4
-```
-
-`bbr` will run to completion and output the time it took to bring all the ONUs to the `dhcp_ack` state.
-If the `bbr` process doesn't exit, it means something went wrong.
-
-## Debugging and issue reporting
-
-If you are experiencing issues with `bbr` please capture:
-- `bbr` logs
-- `bbsim` logs
-- `bbsimctl onu list` output
-
-You can use these commands to capture `bbsim` and `bbr` logs during execution:
-
-```bash
-$ DOCKER_RUN_ARGS="-onu 16 -pon 4" make docker-run 2>&1 | tee bbsim.logs
-```
-
-```bash
-$ ./bbr -onu 16 -pon 4 2>&1 | tee bbr.logs
-```
-
-And this command to retrieve the list of onus in the system (run this command once `bbr` is hanging but before terminating `bbsim`):
-
-```bash
-docker exec bbsim bbsimctl onu list > onu.list
-```

-# ONU State Machine
-
-In `BBSim` the device state is createdtained using a state machine library: [fsm](https://github.com/looplab/fsm).
-
-Here is a list of possible state transitions in BBSim:
-
-|Transition|Starting States|End State| Notes |
-| --- | --- | --- | --- |
-| - | - | created |
-| discover | created | discovered |
-| enable | discovered, disabled | enabled |
-| receive_eapol_flow | enabled, gem_port_added | eapol_flow_received |
-| add_gem_port | enabled, eapol_flow_received | gem_port_added | We need to wait for both the flow and the gem port to come before moving to `auth_started` |
-| start_auth | eapol_flow_received, gem_port_added | auth_started |
-| eap_start_sent | auth_started | eap_start_sent |

+ -h, --help Show this help message
+
+ Available commands:
+ completion generate shell compleition
+ config generate bbsimctl configuration
+ log set bbsim log level
+ olt OLT Commands

+
+Quickstart
+----------
+
+BBSim (a.k.a. BroadBand Simulator) is a tool designed to emulate an `Openolt <https://github.com/opencord/openolt>`_
+compatible device.
+
+In order to use BBSim you need to have:
+
+- a Kubernetes cluster
+- helm
+- a working installation of VOLTHA
+
+We strongly recommend the utilization of `kind-voltha <https://github.com/ciena/kind-voltha>`_ to setup such environment.
+
+Installation
+------------
+
+Once VOLTHA is up and running, you can deploy BBSim with this command:
+
+.. code:: bash
+
+ helm install -n bbsim cord/bbsim
+
+The BBSim installation can be customized to emulate multiple ONUs and multiple PON Ports:
+
+.. code:: bash
+
+ helm install -n bbsim cord/bbsim --set onu=8 --set pon=2
+
+Once BBSim is installed you can verify that it's running with:
+
+.. code:: bash
+
+ kubectl logs -n voltha -f $(kubectl get pods -n voltha | grep bbsim | awk '{print $1}')
+
+Provision a BBSim OLT in VOLTHA
+-------------------------------
+
+Create the device:
+
+.. code:: bash
+
+ voltctl device create -t openolt -H $(kubectl get -n voltha service/bbsim -o go-template='{{.spec.clusterIP}}'):50060
+
+Enable the device:
+
+.. code:: bash
+
+ voltctl device enable $(voltctl device list --filter Type~openolt -q)

+
+ONU State Machine
+=================
+
+In ``BBSim`` the device state is createdtained using a state machine
+library: `fsm <https://github.com/looplab/fsm>`__.
+
+Here is a list of possible state transitions in BBSim:
+
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| Transition | Starting States | End State | Notes |
++================================+========================================================================================+================================+===============================================================================================+
+| | | created | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| discover | created | discovered | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| enable | discovered, disabled | enabled | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| receive_eapol_flow | enabled, gem_port_added | eapol_flow_received | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| add_gem_port | enabled, eapol_flow_received | gem_port_added | We need to wait for both the flow and the gem port to come before moving to ``auth_started`` |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| start_auth | eapol_flow_received, gem_port_added | auth_started | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| eap_start_sent | auth_started | eap_start_sent | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| eap_response_identity_sent | eap_start_sent | eap_response_identity_sent | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| eap_response_challenge_sent | eap_response_identity_sent | eap_response_challenge_sent | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| eap_response_success_received | eap_response_challenge_sent | eap_response_success_received | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| auth_failed | auth_started, eap_start_sent, eap_response_identity_sent, eap_response_challenge_sent | auth_failed | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| start_dhcp | eap_response_success_received | dhcp_started | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| dhcp_discovery_sent | dhcp_started | dhcp_discovery_sent | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| dhcp_request_sent | dhcp_discovery_sent | dhcp_request_sent | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| dhcp_ack_received | dhcp_request_sent | dhcp_ack_received | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+| dhcp_failed | dhcp_started, dhcp_discovery_sent, dhcp_request_sent | dhcp_failed | |
++--------------------------------+----------------------------------------------------------------------------------------+--------------------------------+-----------------------------------------------------------------------------------------------+
+
+In addition some transition can be forced via the API:
+
++---------------------+----------------------------------------------------------------------------+-----------+---------------------------------------------------------------------------------------------------------+
+| End StateTransition | Starting States | End State | Notes |
++=====================+============================================================================+===========+=========================================================================================================+
+| disable | eap_response_success_received, auth_failed, dhcp_ack_received, dhcp_failed | disabled | Emulates a devide mulfunction. Sends a ``DyingGaspInd`` and then an ``OnuIndication{OperState: 'down'}``|
