Expand description

PTP / IEEE 1588 (Precision Time Protocol) implementation for the rTime time synchronization daemon.

Covers the message codec, the Best Master Clock Algorithm (BMCA), the datasets that describe a PTP port and clock, and the end-to-end delay computation used to derive offset from Sync/Follow_Up/Delay_Req/Delay_Resp exchanges.

§Modules

  • message — PTP message header and body codec.
  • announce — Announce message handling.
  • bmca — Best Master Clock Algorithm (dataset comparison and master selection).
  • dataset — default/current/parent/time-properties datasets.
  • delay — end-to-end delay and offset computation.
  • port — PTP port state machine.
  • tlv — TLV (type-length-value) extension encoding.
