implementations implement to receive and send messages to the CLAMP runtime and to handle
Control Loop Element state.
-.. warning:: To be completed
+Terminology
+-----------
+- Broadcast message: a message for all participants (participantId=null and participantType=null)
+- Message to a participant: a message only for a participant (participantId and participantType properly filled)
+- MessageSender: a class that takes care of sending messages from participant-intermediary
+- GUI: graphical user interface, Postman or a Front-End Application
+
+Inbound messages to participants
+--------------------------------
+- PARTICIPANT_REGISTER_ACK: received as a response from controlloop runtime server as an acknowledgement to ParticipantRegister message sent from a participant
+- PARTICIPANT_DEREGISTER_ACK: received as a response from controlloop runtime server as an acknowledgement to ParticipantDeregister message sent from a participant
+- CONTROL_LOOP_STATE_CHANGE: a message received from controlloop runtime server for a state change of controlloop
+- CONTROL_LOOP_UPDATE: a message received from controlloop runtime server for a controlloop update with controlloop instances
+- PARTICIPANT_UPDATE: a message received from controlloop runtime server for a participant update with tosca definitions of controlloop
+- PARTICIPANT_STATUS_REQ: A status request received from controlloop runtime server to send an immediate ParticipantStatus from all participants
+
+Outbound messages
+-----------------
+- PARTICIPANT_REGISTER: is sent by a participant during startup
+- PARTICIPANT_DEREGISTER: is sent by a participant during shutdown
+- PARTICIPANT_STATUS: is sent by a participant as heartbeat with the status and health of a participant
+- CONTROLLOOP_STATECHANGE_ACK: is an acknowledgement sent by a participant as a response to ControlLoopStateChange
+- CONTROLLOOP_UPDATE_ACK: is an acknowledgement sent by a participant as a response to ControlLoopUpdate
+- PARTICIPANT_UPDATE_ACK: is an acknowledgement sent by a participant as a response to ParticipantUpdate
+
+Design of a PARTICIPANT_REGISTER message
+----------------------------------------
+- A participant starts and send a PARTICIPANT_REGISTER message
+- ParticipantRegisterListener collects the message from DMaap
+- if participant is not present in DB, it saves participant reference with status UNKNOWN to DB
+- if participant is present in DB, it triggers the execution to send a PARTICIPANT_UPDATE message to the participant registered (message of Priming)
+- the message is built by ParticipantUpdatePublisher using Tosca Service Template data (to fill the list of ParticipantDefinition)
+- It triggers the execution to send a PARTICIPANT_REGISTER_ACK message to the participant registered
+- MessageIntercept intercepts that event, if PARTICIPANT_UPDATE message has been sent, it will be add a task to handle PARTICIPANT_REGISTER in SupervisionScanner
+- SupervisionScanner starts the monitoring for participantUpdate
+
+Design of a PARTICIPANT_DEREGISTER message
+------------------------------------------
+- A participant starts and send a PARTICIPANT_DEREGISTER message
+- ParticipantDeregisterListener collects the message from DMaap
+- if participant is not present in DB, do nothing
+- if participant is present in DB, it triggers the execution to send a PARTICIPANT_UPDATE message to the participant registered (message of DePriming)
+- the message is built by ParticipantUpdatePublisher using Tosca Service Template data as null
+- ParticipantHandler removes the tosca definitions stored
+- It triggers the execution to send a PARTICIPANT_DEREGISTER_ACK message to the participant registered
+- Participant is not monitored.
+
+Design of a creation of a Control Loop Type
+-------------------------------------------
+- If there are participants registered with CL-runtime, it triggers the execution to send a broadcast PARTICIPANT_UPDATE message
+- the message is built by ParticipantUpdatePublisher using Tosca Service Template data (to fill the list of ParticipantDefinition)
+- Participant-intermediary will receive a PARTICIPANT_UDPATE message and stores the Tosca Service Template data on ParticipantHandler
+
+Design of a deletion of a Control Loop Type
+-------------------------------------------
+- if there are participants registered, CL-runtime triggers the execution to send a broadcast PARTICIPANT_UPDATE message
+- the message is built by ParticipantUpdatePublisher with an empty list of ParticipantDefinition
+- It deletes the Control Loop Type from DB
+- Participant-intermediary will receive a PARTICIPANT_UDPATE message and deletes the Tosca Service Template data on ParticipantHandler
+
+Design of a creation of a Control Loop
+--------------------------------------
+- CONTROL_LOOP_UPDATE message with instantiation details and UNINITIALISED state is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_UPDATE message and sends the details of ControlLoopElements to participants
+- Each participant performs its designated job of deployment by interacting with respective frameworks
+
+Design of a deletion of a Control Loop
+--------------------------------------
+- CONTROL_LOOP_STATE_CHANGE message with UNINITIALISED state is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_STATE_CHANGE message and sends the details of ControlLoopElements to participants
+- Each participant performs its designated job of undeployment by interacting with respective frameworks
+
+Design of "issues control loop commands to control loops" - case UNINITIALISED to PASSIVE
+-----------------------------------------------------------------------------------------
+- CONTROL_LOOP_STATE_CHANGE message with state changed from UNINITIALISED to PASSIVE is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_STATE_CHANGE message and sends the details of state change to participants
+- Each participant performs its designated job of state change by interacting with respective frameworks
+
+Design of "issues control loop commands to control loops" - case PASSIVE to UNINITIALISED
+-----------------------------------------------------------------------------------------
+- CONTROL_LOOP_STATE_CHANGE message with state changed from PASSIVE to UNINITIALISED is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_STATE_CHANGE message and sends the details of state change to participants
+- Each participant performs its designated job of state change by interacting with respective frameworks
+
+Design of "issues control loop commands to control loops" - case PASSIVE to RUNNING
+-----------------------------------------------------------------------------------
+- CONTROL_LOOP_STATE_CHANGE message with state changed from PASSIVE to RUNNING is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_STATE_CHANGE message and sends the details of state change to participants
+- Each participant performs its designated job of state change by interacting with respective frameworks
+
+Design of "issues control loop commands to control loops" - case RUNNING to PASSIVE
+-----------------------------------------------------------------------------------
+- CONTROL_LOOP_STATE_CHANGE message with state changed from RUNNING to PASSIVE is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_STATE_CHANGE message and sends the details of state change to participants
+- Each participant performs its designated job of state change by interacting with respective frameworks
+
+Design of a PARTICIPANT_STATUS message
+--------------------------------------
+- A participant sends a scheduled PARTICIPANT_STATUS message
+- This message will hold the state and healthStatus of all the participants running actively
+- PARTICIPANT_STATUS message holds a special attribute to return Tosca definitions, this attribute is populated only in response to PARTICIPANT_STATUS_REQ
+
+Design of a CONTROLLOOP_UPDATE_ACK message
+------------------------------------------
+- A participant sends CONTROLLOOP_UPDATE_ACK message in response to a CONTROLLOOP_UPDATE message.
+- For each CL-elements moved to the ordered state as indicated by the CONTROLLOOP_UPDATE
+- ControlLoopUpdateAckListener in CL-runtime collects the messages from DMaap
+- It checks the status of all control loop elements and checks if the control loop is primed
+- It updates the controlloop in DB accordingly
+
+Design of a CONTROLLOOP_STATECHANGE_ACK is similar to the design for CONTROLLOOP_UPDATE_ACK

Participant Simulator
#####################
-To be completed.
+This can be used for simulation testing purpose when there are no actual frameworks or a full deployment.
+Participant simulator can edit the states of ControlLoopElements and Participants for verification of other controlloop components
+for early testing.
+All controlloop components should be setup, except participant frameworks (for example, no policy framework components
+are needed) and participant simulator acts as respective participant framework, and state changes can be done with following REST APIs
+
+Participant Simulator API
+=========================
+
+This API allows a Participant Simulator to be started and run for test purposes.
