NTP Throughput for EC20S

Question

How many NTP requests can the model EC20S ?

Answer

The Epsilon Clock model EC20S can typically handle 100 NTP requests per second.

The EC20S is a basic NTP server accessible through the port number 123 and responds with a properly formatted NTP server response in request to client messages. It does not offer enterprise-quality NTP server features such as is available on the Spectracom SecureSync master clock/time server.

The EC20S NTP server support two stratum levels based on the unit's SFN status (which corresponds to the reliability / accuracy of the time transferred via NTP):
Stratum = 1 When SFN status is ON
Stratum = 15 When SFN status is OFF

See the EC20S users manual for more information.
