N2	IEEE1588 - Precise Time Protocol

This course describes the PTP protocol and provides implementation examples

Objectives The course explains the IEEE1588 standard and details some implementation solutions The BMC algorithm is described The course emphasizes the way to implement IEEE1588 on an Ethernet system and highlights the boundary between software and hardware The new features of P1588 (aka IEEE1588v2) are studied A more detailed course description is available on request at training@ac6-training.com

Prerequisites Knowledge of Ethernet and switching is needed, see our course reference N1 - Ethernet and switching course

Introduction Objectives of the standard The need for synchronization Definitions PTP Clock Synchronization Model The PTP messages PTP systems, acyclic graph structure Message filtering Clock properties, stratum, identifier Subdomain properties PTP Protocol Specification Model of a subdomain of PTP clocks State behavior of clocks Protocol engine state machine Clock data sets, initialisation properties Messaging and internal event behavior of clocks Sync-event time-out mechanism Synchronization changes of the local clock Best Master Clock algorithm Clock variance computation Local clock synchronization Physical requirements for PTP implementations Management messages
