The price of the NTP server depends on many factors. To understand the price of the NTP server, we first need to know what the NTP server is. NTP server is usually a time server based on NTP network time protocol. NTP network time protocol is a protocol that can synchronize computers. The NTP server takes the satellite signal as the time reference and outputs time information such as NTP network, serial port and second pulse to calibrate the equipment. It can provide high precision time information.
The NTP server is a protocol for synchronizing the computer clock on the network computer. The time information used by NTP is UTC time and the time of the computer is synchronized. The time accuracy is millisecond. The NTP server can identify the check time information to determine whether the time information is really from the NTP server, thus providing an anti-jamming protection mechanism to prevent malicious attacks.
NTP servers vary according to specific functions and parameters. The NTP server will affect the price according to the signal source. The general NTP server receives the single GPS satellite signal or the single Beidou satellite signal, but also has the NTP server to receive the GPS Beidou satellite signal and the CDMA signal. The NTP server will affect the price according to the number of output time signals.
NTP server is mainly based on NTP network time service, but according to user needs, other timing methods will be added, such as IRIG-B code, IEEE 1588, sub pulse, time pulse, serial port time information and so on, which will affect the price. The number of gigabytes or NTP requests per NTP server network interface will affect the price of NTP server.
At present, according to the different clock sources of the NTP server, the timing accuracy will be different and the price will be different. The timing accuracy of the NTP server is the accuracy of synchronous clock relying on the internal clock source without the external reference source. SYN2136 Beidou NTP network time allocation clock source can choose ordinary crystal oscillator, temperature compensation crystal oscillator, constant temperature crystal oscillator, rubidium atomic clock, tame constant temperature crystal oscillator module, tame rubidium clock module and so on. The average time error of common crystal oscillator is 2-3 seconds. The error of temperature compensation crystal oscillator is less than 1s within a day. The error of constant temperature crystal oscillator is several milliseconds a day, and the rubidium clock will be more precise than the constant temperature crystal oscillator. So choosing different clock sources, the NTP server will also have different prices. SYN2136 Beidou NTP network time in addition to the above functions, also increased the firewall, SYN-flood defense, software hardware watchdog, QoS function, NTP running state view, network diagnosis, these functions also affect its price.
According to the analysis of the above functions and prices, SYN2136 Beidou NTP network time server can meet various functions and indicators, and the NTP server price is moderate, which is the preferred timing equipment in all walks of life.
