Overview of TimeVault

1.2Overview of TimeVault

TimeVault is a high-performance, internet-enabled Network Time Protocol (NTP) server that operates in a secure access environment and provides time to multiple clients with extreme accuracy. To provide trusted time and guard against any denial of service, TimeVault uses GPS as a primary synchronization source, backed up by ACTS and NTP as secondary and tertiary sources, respectively.

TimeVault provides network time synchronization over Ethernet connected networks via Network Time Protocol (NTP), developed by Dr. David Mills at the University of Delaware. TimeVault currently supports versions 2 and higher of the NTP, RFC-1305, as well as the Simple Network Time Protocol (SNTP), RFC-2030. In addition, TimeVault responds to TIME protocol requests, RFC-868. For details about these protocols, refer to Appendix A and Appendix B in this manual.

The main feature of TimeVault’s web interface is its ability to perform setup and control operations from a remote location, using the Internet or TCP/IP LAN (see Chapter 3). The protocol used is either Telnet or HTTP. TimeVault has an RJ-45 Ethernet connector on its NET Port, providing NTP and IP access, and a 9-pin D serial connector for serial input/output.
