Chapter 7 NTP Configuration

As the network topology gets more and more complex, it becomes important to

synchronize the clocks of the equipment on the whole network. Network Time Protocol

(NTP) is the TCP/IP that advertises the accurate time throughout the network.

NTP ensures the consistency of the following applications:

For the increment backup between the backup server and client, NTP ensures the

clock synchronization between the two systems.

For multiple systems that coordinate to process a complex event, NTP ensures

them to reference the same clock and guarantee the right order of the event.

Guarantee the normal operation of the inter-system (Remote Procedure Call).

Record for an application when a user logs in to a system, a file is modified, or

some other operation is performed.

The following figure illustrates the basic operating principle of NTP:
