SNTP Configuration
Overview
Network Time Protocol (NTP) is designed for time synchronization on network
devices. Another protocol, Simple Network Time Protocol(SNMP) can be used
to synchronize the network time, too.
NTP protocol can be used across various platforms and operating systems, and
provide precise time calculation (1-50ms precision) and prevent from latency
and jitter in the network. NTP also provides the authentication mechanism with
high security level. However, NTP algorithm is complicated and demands better
system.
As a simplified version of NTP, SNTP simplifies the algorithm of time calculation
but also has great performance, with precision of about 1s.
SNTP Client is totally compatible with the NTP Server due to the consistency of
the SNTP and NTP messages.
Working Principles
SNTP works in the way of Client/Server. The standard Server system time is set
by receiving the GPS signal or the atomic clock. The Client obtains its accurate
time from the service time accessing the server regularly, and adjusts its system
clock to synchronize the time.
