Abstract

This component implements a gPTP (IEEE 802.1AS) time synchronization slave daemon that receives time synchronization data from network and publishes it to IPC for client applications.

Specification

The component provides gPTP slave functionality with network message processing and IPC publishing:

• Component Initialization (comp_req__time_slave__initialization)

• Component Shutdown (comp_req__time_slave__shutdown)

• Domain Number Filtering (comp_req__time_slave__domain_filtering)

• Sync Message Reception (comp_req__time_slave__sync_reception)

• Follow_Up Message Processing (comp_req__time_slave__followup_processing)

• Offset Calculation (comp_req__time_slave__offset_calculation)

• PDelayReq Transmission (comp_req__time_slave__pdelay_req)

• Peer Delay Computation (comp_req__time_slave__pdelay_computation)

• PHC Offset Adjustment (comp_req__time_slave__phc_offset)

• PHC Frequency Adjustment (comp_req__time_slave__phc_frequency)

• Synchronization Timeout Det... (comp_req__time_slave__sync_timeout)

• Time Leap Future Detection (comp_req__time_slave__leap_future)

• Time Leap Past Detection (comp_req__time_slave__leap_past)

• Time Sync Data Publishing (comp_req__time_slave__sync_publishing)

• Publish Interval (comp_req__time_slave__publish_interval)

• Linux Platform Support (comp_req__time_slave__platform_linux)

• QNX Platform Support (comp_req__time_slave__platform_qnx)

• Hardware Timestamping (comp_req__time_slave__hw_timestamping)

• Error Reporting (comp_req__time_slave__error_reporting)

• Synchronization Diagnostics (comp_req__time_slave__diagnostics)
