24.1 SNTP introduce

At present, the Internet has been widely used in the communication protocol to realize

network time synchronization, namely NTP (Network Time Protocol Network Time Protocol), a

protocol is a simplified version of the NTP protocol, namely SNTP (Simple Network Time

Protocol simple network time protocol).

The NTP protocol can span a variety of platforms and operating system, with a very

sophisticated algorithm, so the effect of delay and jitter is almost not affected by the network, can

provide 1-50ms accuracy while providing.NTP authentication mechanism, the security level is

very high. But the complicated NTP algorithm, the system requires a higher.

SNTP (Simple Network Time Protocol) is a simplified version of NTP, in the

implementation of the calculation time using a simple algorithm, the performance is high, and the

accuracy can generally reach about 1 second, but also basically meet the needs of most occasions.

Because the message of SNTP and NTP message are completely identical, the SNTP
