Can your servo-loop algorithm steer out queuing noise better than the rest? Enter the Time-stick servo-loop contest kickstart.
How to Enter

   1. Register for the contest kickstart here

   2. Download the latest drivers from: https://github.com/opencomputeproject/Time-Appliance-Project/tree/master/Incubation/Hardware/TimeStick

Kickstart Format
  • A time stick will be provided at ISPCS for the contest kickstart
  • Contestants will be evaluated during coffee breaks at the Symposium 
  • Accuracy with Impairment measurement
  • Load ptp4l or own PTP app on a notebook computer and update the PLL with their contest entry algorithm.
  • Test bed is a Meinberg Grandmaster clock, with a Calnex Paragon between the GM and the Notebook under test providing network impairments so that it looks like a heavily loaded network with PDV and occasional dropped message.  Either Meinberg or Calnex can measure the accuracy. Equipment will be located between the Meinberg and Calnex exhibit booths
  1. Whoever can track the GM closest for a five-minute test after a five-minute PLL warmup period will be entered into a drawing.  
  2. Top contestants compete in semifinals on final day with code modifications.
Measurement Methods
  • PDV impairments, run G.8275.2
  • Standard ITU metrics like max|TE| or dTEH
  • RMS error
