Network clock synchronization server mainly focuses on network clock synchronization function does not describe the clock signal source.
Beidou clock synchronization server describes the clock signal source is the Beidou system, but also explains the clock synchronization function.
Network clock synchronization server and Beidou clock synchronization server in addition to the clock signal source, the basic function is similar.
Computer network systems recommended to set up their own clock server, recommended by the Beijing quasi-electronic technology HR-901GB type?
At present, the time of each host and server and other network devices in the computer network is basically in an unorganized state. With the continuous emergence of computer network applications, computer time synchronization issues become more and more important things. Take the Unix system as an example, the accuracy of time affects almost all file operations. If a machine time is inaccurate, for example, from the time ahead of the machine to create a file, with ls view, to the current time minus the time of the file shown in the modification will be a negative value, this problem for the network file servers is a disaster, the reliability of the file will no longer exist. To avoid local errors, you can get time from the network, the command is rdate, so that the system clock can be synchronized with the public **** source. But an error in this public **** time source will have a domino effect, and the time of all machines synchronized with it will be wrong.

Synchronization is even more important when it comes to security devices on the network. The logs generated by these devices must reflect the exact time. Especially when dealing with busy data, it is almost impossible to correlate logs from different sources if the time is not synchronized. Once log files are not correlated, security correlation tools are useless. An unsynchronized network means that organizations have to spend a lot of time manually tracking security events. Now let's look at how you can synchronize your network and make security logs present accurate time.
