.. Network clock synchronization system
- is a high-tech, intelligent and independently working high-precision network time synchronization product based on the
- protocol developed by Jinan Weishang Electronics Co., Ltd. . The device obtains standard clock signal information from
- or Beidou geostationary satellites, and transmits this standard time information in the network. Devices in the network that require time signals such as computers,
-, Devices such as controllers can then be synchronized to standard clock signals. When the device uses
- and Beidou receiver
,
- at the same time, the priority can be flexibly configured and the time source can be switched intelligently. The device uses a built-in constant-temperature crystal oscillator to keep time, and the timekeeping accuracy can reach
-.
.. Network clock synchronization system
- Adopts modular device, can be configured with multiple network ports, and the network ports are physically isolated from each other, fully ensuring data security, and can be set up on the same network segment or different network segments , with redundancy, the failure of a certain network port will not affect the normal operation of other network ports.
- (
r
-, Network Time Protocol) is a time synchronization protocol defined by
-, used between distributed time servers and clients Perform time synchronization.
- Transmission is based on
- messages, and the
- port number used is
-. The purpose of using
- is to synchronize the clocks of all devices with clocks in the network so that the clocks of all devices in the network are consistent, so that the devices can provide multiple applications based on unified time. For a local system running
-, it can not only accept synchronization from other clock sources, but also can be used as a clock source to synchronize other clocks, and can synchronize with other devices.
- Application
- For each device in the network, it is impossible to modify the system clock by relying on the administrator to manually enter commands. Not only is the workload huge, but the accuracy of the clock cannot be guaranteed. sex. Through
-, the clocks of devices in the network can be synchronized quickly, while ensuring high accuracy.
- Mainly used in situations where the clocks of all devices in the network need to be consistent, such as:
- In network management, when analyzing log information and debugging information collected from different devices, it is necessary Use time as a reference.
- The billing system requires the clocks of all devices to be consistent.
- To complete certain functions, such as regularly restarting all devices in the network, the clocks of all devices are required to be consistent.
- When multiple systems collaborate to process the same complex event, in order to ensure the correct execution sequence, multiple systems must refer to the same clock.
- When performing incremental backup between the backup server and clients, the clocks between the backup server and all clients are required to be synchronized.
