7.3.1 Description of PTP Functions
Precise time management is required for running time-critical applications via
a LAN.
The IEEE 1588 standard with the Precision Time Protocol (PTP) describes a
procedure that determines the best master clock in a LAN and thus enables
precise synchronization of the clocks in this LAN.
This procedure enable the synchronization of the clocks involved to an
accuracy of a few 100 ns. The synchronization messages have virtually no
effect on the network load. PTP uses Multicast communication.
