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 info@ac6-formation.com

Prerequisites
	Knowledge of Ethernet is recommended (see our course reference N1)
