SNTP Servers
SNTP is the acronym for Simple Network Time Protocol, which is an adaptation of the Network Time Protocol (NTP) used to synchronize computer clocks in the Internet.
SNTP time servers are ideally stand alone systems used by computers to receive time from a time source. The SNTP server then sets and synchronizes the time on a computer IT system or enterprise.
What a Symmetricom SNTP Server Does
Symmetricom's SNTP servers ensure that IT operations can effectively and systematically manage the setting of time on their domain of systems. This provides critical support to the integrity of a business.
The SNTP on Symmetricom's time servers should be used only at the extremities of the synchronization subnet. SNTP clients should operate only at the highest stratum of the subnet and in configurations where no NTP or SNTP client is dependent on another SNTP client for synchronization. SNTP time servers should operate only at the Stratum 1 root of the subnet and then only in configurations where no other source of synchronization other than a reliable radio clock is available.
Stratum 1 and Stratum 2 in relation to SNTP Servers
Time can be passed from one time source to another, typically starting from a reference clock connected to a Stratum 1 SNTP server. NTP time servers synchronized to a Stratum 1 NTP server will be Stratum 2. Stratum 1 NTP time servers source their time from a Stratum 0 device. Stratum 2 and beyond obtain their time from Stratum 1 NTP time servers. The further away a network is from a primary source, the greater the chance of signal degradations due to variations in communications lines, and so forth.
