Unicast NTP Client Software

What does 'Unicast' mean?

Unicast is the term used to describe communication where a piece of information is sent from one point to another point. A unicast client is a device that sends a request to a time server at a specific address. A reply is then sent and the NTP unicast client determines the time, accounting for any delays and offsets.

Unicast uses IP delivery which, for the NTP protocol, is the session-based User Datagram Protocol (UDP). Each unicast client that connects to the server takes up additional bandwidth. For example, if you have 10 clients requesting the time using 256 bytes (128 bytes x 2), those clients as a group are taking up 2560 bytes (2.5 Kb). If you have only one client playing the 256 bytes, only 256 bytes are being used. The values quoted here are derived from Understanding and using the Network Time Protocol.

Client servers, workstations and computers running the TimeSync NTP client software will request the time from the NTP Time Server via a number of time stamps to determine signal lag. The time is adjusted taking the lag into consideration, checked against the current system time and if there is a difference the TimeSync NTP Client will correct the system time so that all computers will be synchronised to correct UTC time.

Key Benefits

  • Correct time synchronised across your network using NTP
  • High accuracy - time stamping on 'send'
  • Auditable - event log and file logging options
  • Secure - locked to an IP address
