Abstract:

SIPRNET, the Secret Internet Protocol Routing Network, is DoDs wide area network for encrypted hosts handling classified traffic. It is managed by the Defense Information Systems Agency. In 1997 the U.S. Naval Observatory established network time synchronization service on SIPRNET, with dedicated servers providing Network Time Protocol NTP. These servers are synchronized to the USNO Master Clocks. An overview of time server design is presented, with details on expected accuracy and accessibility.
