Network Time Server
What is an NTP Network Time Server?
NTP stands for Network Time Protocol, which is a way of transferring data over an Ethernet (or other compatible network) LAN (Local Area Network).
Our range of network timeservers distribute highly accurate time information to all devices on a LAN requiring accuarate time information.
Stratum 1 NTP Time Server
‘Strata’ refer to the hierarchical levels used by Network Time Protocol (NTP) to disseminate time information over a network.
Stratum 1 refers to a device receiving time information directly from the Stratum 0 device (e.g. caesium clock) via serial (RS232, RS422, etc) or even timecode (IRIG-B, AFNOR, NASA codes, etc).
The connection can be external, but some Stratum 1 timeservers have the Stratum 0 device built inside them for convenience. The time delay accuracy is generally less than 1 millisecond.
Stratum 2 refers to devices that are connected to the Stratum 1 timeserver via a network. For example, computers on a LAN are Stratum 2 devices. Each Stratum 2 device can be linked this way to more than one Stratum 1 time server to optimise the information it receives. The delay accuracy can usually range from 10 to 100 milliseconds.
Stratum 3 is the next level connected via a network path, and so on.
All our time and frequency standards and modular timing systems are Stratum 1, 2 or 3 NTP time servers.
