In Init_LNS Response, If Status indicates success, the initialisation of the lean network services is completed. The value error indicates invalid parameters. The network supervisor uses stop_Is_Request to stop the network management processes (see C1ause_13) of the lean network services. In top LNS Response, if tatus indicates success, the lean network services are stopped after completing the requested actions. The value error indicates that the lean network services terminated the management processes after expiration of tINS Termrnation The management processes are reset without completing all requested actions. 12.2.2 Network startup and shutdown The network supervisor uses Network_Startup_Request to start up the MOST network. In Network Startup_Response, if Status indicates success, the network is active. The value error indicates failure during startup. The network supervisor uses Network_Shutdown_Request to shut down the MOST network. In Network Shutdown_Response, if Status indicates success, the network is shut down. The value error indicates that the request is currently not allowed. The lean network services use the Network Statu. Event to inform the network supervisor about a change in either network availability or a related parameter. 12.2.3 Node discovery The network supervisor uses Node_Discovery_Start_Request to commence node discovery. In Node Discovery_Start_Response, if Status indicates success, the node discovery process is running. The value error indicates missing preconditions, for example, a successful network startup. The lean network services use Node_Discovery_Event to inform the network supervisor that a node is discovered. The network supervisor compares the signature to the network descriptor and sends Node_Welcome_Request. When the remote node is added to the network, the network supervisor sends Node_Availability_Set_Request (available). The network supervisor uses Node_Welcome_Request to instruct the lean network services to send Welcome StartResult to a remote node. In Node_Welcome_Response, if status indicates success, the node identified by the signature is added to the network and becomes part of the network configuration. The value error indicates a transmission error during the “Welcome sequence for the corresponding node. The network supervisor uses Node_Availability_Set_Request to set the Availability property of a node. In Node_Availability_Set_Response, if Status indicates success, the connection management processes connections related to the corresponding node. The value error indicates invalid parameters. The network supervisor uses Node_DircvryStop_Request to terminate node discovery....
