zUnicast—Sends a request packet periodically to the Primary host. If
communication with the Primary host fails, the request will be sent to the
Secondary host.
zBroadcast/Multicast—Listen for any broadcasts from an NTP/SNTP
server and then synchronizes its internal clock to the message.
zManycast/Anycast—Sends a request packet as a broadcast on the LAN to
get a response from any NTP/SNTP server. The first response that is
received is used to synchronize its internal clock and then operates in
Unicast mode with that NTP/SNTP server.
