This part contains a description of the basic concepts of the product LEDI Network IN. It
helps you to understand the behavior of the product under various circumstances.
The NTP client software is the very heart of the LEDI Network IN. It performs all the syn -
chronization, the management of the hardware and provides information for the WEB inter -

1.3.1. Synchronization concepts
A/ Clock Correction principles
The objective of the synchronization is to make two clocks indicating the same time. In
the case of NTP based synchronization, the LEDI Network IN clock must indicate the
same time that the NTP server clock.
2/ Some DHCP servers have the ability to copy the DHCP name into the DNS. In this case, you can access the
LEDI Network IN directly by its DHCP name instead of its IP address.
