NTP - UDP/IP

Description:

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with NTP with those for I-I: UDP/IP. The NTP standards include standards required to reliably set time information in a subsystem. The I-I: UDP/IP standards include lower-layer standards that support the Network Time Protocol that allows NTP servers to provide time synchronization services to other NTP servers and clients.
