Description

The created tool is intended for measuring the real precision of synchronization in a network of distributed nodes running real-time operating system. The meassurement is based on observing jitter of synchronously generated signals. The measuring environment consists of:

  • Developed measuring device based on FITKit platform
  • Traffic generator 
  • Software for end nodes that periodically generates the signal minimizing OS latency
This measuring environment enables to measure a degree of synchronization in a distributed system for different interconnecting topology and actual network load.
