Network Time Protocol is used to synchronize the clocks of computers on a network. How accurately it synchronizes the clocks of client computers depends on a number of factors. However, the following timings can be used as a guide: Public Internet NTP Servers: <10ms. Public Internet Servers over asymmetric connection (ADSL): <100ms. NTP Servers on […]

SNTP: All You Need To Know About Simple Network Time Protocol
Simple Network Time Protocol (SNTP) is an Internet Protocol (IP) used to synchronize the clocks of networks of computers. SNTP is a subset of the Network Time Protocol (NTP). The latest version is SNTP v4. It can synchronize seamlessly to full-blown NTP servers. Originally developed for small computers and micro-controllers. Requires less memory and processing […]
Ten Reasons To Buy A NTP Server
The Internet has many NTP servers that can be used to synchronize the time of networks and computers. Most provide a service completely free of charge. So why do organizations need to seriously consider buying a dedicated NTP appliance? Dedicated hardware time references installed locally, within an organization, provide a number of advantages over Internet […]
Network Time Protocol (NTP) Best Practices
By implementing a few best practice principles, organizations can attain robust and reliable timing for their network infrastructure: Install 3 or more redundant Stratum 1 NTP servers. Configure lower stratum clients with at least 3 higher stratum servers. Peer lower stratum devices to share time. Secure NTP communications with authentication. Employ Stratum 1 servers that […]
How to Install and Configure NTP on Linux
NTP can be installed and configured on Linux in a few simple steps: Install the NTP service. Modify the NTP configuration file, ‘/etc/ntp.conf’, with required options. Add reference clock peers to the configuration file. Add drift file location to the configuration file . Add optional statistics directory to the configuration file . Enable and start […]
An Introduction To NTP
Network Time Protocol (NTP) is a standard Internet Protocol (IP) for synchronizing the clocks of computers on a network. NTP coordinates the real time clocks of computers on a network. Developed at the University of Delaware in 1985. It is one of the oldest internet protocols still in use. The latest release is version 4.2. […]
