10? Network? configuration 10.1 General The network descriptor determines the network configuration, the nodes and the streaming connections between them. It can be either edited text-based or by use of a graphical tool. The network descriptor is used to generate a data definition in a format that the lean network services are capable of processing. The tables in the following subclauses contain a column that is titled “stored”. The entries marked with “yes” are contained in the storage format for the network descriptor, while the entries marked with “no” are relevant for the network configuration, which is established during runtime. “Optional” entries, mainly resource handles, are relevant during runtime but may also be pre-configured.
11.2 Requests, responses, and events 11.2.1 Network startup and shutdown The application 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 application 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 network supervisor uses the Network_Status_Event to inform the application about a change in either network availability or a related parameter. 11.2.2 Connection management The application uses Connection_Management_Start_Request to start connection management. In Connection_Management_Start_Response , if Status indicates success , the connection management is processing the network descriptor. The value error indicates a missing resource, which is dealt with by the network supervisor, typically by initialising the lean network services. The application uses Connection_Management_Stop_Request to terminate connection management. In Connection_Management_Stop_Response , if Status indicates success , the connection management has stopped processing. The value error indicates that resources could not be released. Before starting connection management again, the lean network services should be initialised by the network supervisor. The application uses Path_Activation_Set_Request to set the Activation of a path. In Path_Activation_ Set_Response , if Status indicates success , the connection management processes connections related to the corresponding path. The value error indicates invalid parameters.
