Objectives of 1588
• Sub-microsecond synchronization of real-time
clocks in components of a networked distributed
measurement and control system
• Intended for relatively localized systems typical
of industrial automation and test and
measurement environments.
• Applicable to local areas networks supporting
multicast communications (including but not
limited to Ethernet)

•Simple, administration free installation
•Support heterogeneous systems of clocks with
varying precision, resolution and stability
•Minimal resource requirements on networks
and host components.
