Datarouter Services

Datarouter DLT Server		status: valid security: NO safety: QM
reqtype: Functional satisfies: feat_req__logging__compat_dlt, feat_req__logging__log_sinks_network belongs to: comp__data_router
Datarouter shall implement DLT server component. Datarouter provides the functionality to send messages using DLT protocol over UDP multicast transport.
comp_req__data_router__dlt_server		Component Requirement

DLT Multiple Channel Support		status: valid security: NO safety: QM
reqtype: Functional satisfies: feat_req__logging__compat_dlt, feat_req__logging__config_log_filter, feat_req__logging__config_entity_id belongs to: comp__data_router
DLT server shall support multiple log channels as specified in AUTOSAR Diagnostic, Log and Trace Protocol Specification. The following parameters shall be configurable statically via a deployment-specific configuration file (<data_router binary location>/./etc/log-channels.json): Number and names of channels, Network configuration for channel output, Log level threshold per channel, Log channel assignments per application/context.
comp_req__data_router__dlt_multiple_channels		Component Requirement

DLT Message Filtering		status: valid security: NO safety: QM
reqtype: Functional satisfies: feat_req__logging__filtering_log_levels, feat_req__logging__filtering_entity_id, feat_req__logging__config_log_filter belongs to: comp__data_router
DLT server shall support filtering of messages within each channel. The filter shall be parametrized with application ID, context ID, log level threshold. Initial filter set shall be part of channel configuration file, located in the following path: <data_router binary location>/../etc/log-channels.json.
comp_req__data_router__dlt_message_filtering		Component Requirement

DLT Verbose Messages		status: valid security: NO safety: QM
reqtype: Functional satisfies: feat_req__logging__compat_dlt belongs to: comp__data_router
DLT server shall provide support for verbose DLT messages. Messages sent from mw::log library shall be sent via DLT using verbose mode.
comp_req__data_router__dlt_verbose_messages		Component Requirement

DLT Quotas

DLT Bandwidth Quota Configuration		status: valid security: NO safety: QM
reqtype: Functional satisfies: feat_req__logging__config_buffer_size, feat_req__logging__resource_comm_channel belongs to: comp__data_router
The component shall have the DLT bandwidth quota configuration in the file located at ./etc/log-channels.json relative to the application specific location /opt/.
comp_req__data_router__dlt_bw_quota_config		Component Requirement

DLT Quota Bandwidth Reduction		status: valid security: NO safety: QM
reqtype: Functional satisfies: feat_req__logging__message_loss_handling, feat_req__logging__qos_message_handling belongs to: comp__data_router
It shall be possible to configure the action to drop DLT messages when a quota is exceeded. Note: The configuration shall be provided as an attribute as part of the DLT quota configuration file (DLT Bandwidth Quota Configu... (comp_req__data_router__dlt_bw_quota_config)).
