Stratum 2
Stratum 2 refers to a layer in the hierarchical structure of the Network Time Protocol (NTP). It is one level above Stratum 3 and typically consists of servers that synchronize their time with Stratum 1 servers, which are directly connected to accurate time sources like atomic clocks or GPS.
In this system, Stratum 2 servers provide time synchronization to clients and lower stratum servers. This helps distribute accurate time across the network, ensuring that devices maintain consistent time settings, which is crucial for various applications, including data logging and scheduling tasks.
