18.3 Stratum Levels and Timeservers

     

One thing we haven't mentioned yet is Stratum Levels . A Stratum Level indicates the reliability of a timeserver. Startum-1 servers are the most reliable, Stratum-2 servers are next , and so on. If we are using a GPS/radio receiver, then we will be designated as a Stratum-1 server. You may want to get in contact with Delaware University and ask them to update their list. If you do not want to be accessible on the public Internet, then that is okay. You can configure and use a Stratum-1 server only for the machines in your network. If you are setting up a timeserver for your organization, you may specify it as a Stratum-2 server; however, you should check the Rules of Engagement at the University of Delaware Web site on what is required to set up a recognized Stratum-2 server. Lower Stratum Levels may mean only a small degradation in time accuracy, but an increase in the attractiveness as a time source; this can be reflected in the dispersion figures, which could mean that your NTP daemon is using a lower stratum level server because it is close, as far as network quality is concerned . When setting up a timeserver, we should consider this: Advertising yourself as a reliable time source when it is evident that you aren't is not good NTP etiquette .
