Sntp Settings - D-Link DES-3350SR User Manual

D-Link DES-3350SR Standalone Layer 3 Switch
Figure 7 - 23. Bandwidth Settings window
To use the bandwidth feature, enter the port or range of ports in the From and To fields. The third field allows you to set the type
of packets being received and/or transmitted by the Switch. Toggle the no_limit setting to Enabled in the fourth field, or if you
prefer, manually enter a value in the Rate field, and then click Apply. Please note that if no_limit is Enabled, the Switch will not
permit you to set the bandwidth rate manually.

SNTP Settings

The DES-3350SR supports Simple Network Time Protocol (SNTP), an adaptation of the Network Time Protocol (NTP). As
specified in RFC-1305 [MIL92], NTP is used to synchronize computer clocks in the global Internet. It provides comprehensive
mechanisms to access national time and frequency dissemination services, organize the time-synchronization subnet, and adjust the
local clock in each participating subnet peer.
The access paradigm is identical to the UDP/TIME Protocol and, in fact, it is usually easy to adapt a UDP/TIME client
implementation to operate using SNTP. Moreover, SNTP is also designed to operate in a dedicated server configuration including
an integrated radio clock. With careful design and control of the various latencies in the system, it is possible to deliver time
accurate to the order of microseconds.
