What is clock synchronization in networking?
Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.
How do I sync NTP?
Synchronize Time on Installed Linux Operating Systems
- On the Linux machine, log in as root.
- Run the ntpdate -u command to update the machine clock. For example, ntpdate -u ntp-time.
- Open the /etc/ntp.
- Run the service ntpd start command to start the NTP service and implement you configuration changes.
What is the importance of NTP?
Network Time Protocol (NTP) is a protocol that allows the synchronization of system clocks (from desktops to servers). Having synchronized clocks is not only convenient but required for many distributed applications. Therefore the firewall policy must allow the NTP service if the time comes from an external server.
How to synchronize clock between client and server?
I am working on a project where a server parses audio files, and then tells clients to play certain sections of audio based on a common clock, the server’s.
How does Network Time Protocol ( NTP ) synchronize your computer’s clock?
The Network Time Protocol (NTP) is for synchronizing the clock of computers on a subnet with the UTC. A host on this subnet may be a primary server, or a secondary server or a client. The primary servers are directly synchronized with a reference atomic clock over the wire (RS232C) or radio.
How often do you need to synchronize the clock on your computer?
As a rule of thumb, the primary servers may be queried every minute and the secondary servers less often, the frequency of synchronization decreasing with increase in the server stratum number. Then there is the dependency on the ambient temperature. The clock oscillator loses oscillations at higher temperatures.
Why do we need a high level of synchronization?
In theory we would need a high level of synchronization as the client nodes might be playing audio right beside each other, and all but the smallest of delays may produce a sound offset noticeable by the human ear. I have been trying to find c code examples of how to address this problem and have had little luck.
