Estimation and Removal of Clock Skew From Network Delay Measurements

Primary Inventors: 

Don Towsley, Ph.D., P. Skelly, and S. Moon


Invention estimates and removes relative skew in synchronization between sender and receiver clocks that are so critical to the accurate assessment and analysis of network performance. A proprietary algorithm along with a linear programming approach gives a far better network managing and monitoring tool.

  • Internet/intranet monitoring tools
  • Cell phones, video streaming, multicast transmission
  • Can be incorporated in internet software and hardware as resident application
  • Error margin of the skew is independent of the magnitude of the skew
  • Skew estimates are superior to existing algorithms
  • Highly accurate
