Title:
NETWORK SYNCHRONIZATION METHOD AND APPARATUS FOR PERFORMING TIME SYNCHRONIZATION BETWEEN NODES
Document Type and Number:
WIPO Patent Application WO/2010/134674
Kind Code:
A3
Abstract:
Provided is a network synchronization method and apparatus for performing a time synchronization between nodes. When a system starts up and the time synchronization between the nodes is initiated, the network synchronization method and apparatus may enhance jitter, wander, and a time synchronization performance by gradually increasing a window size for a propagation time measurement. When a full window of propagation time measurements is collected, the network synchronization method and apparatus may enhance jitter, wander, and the time synchronization performance by applying an exponential to a computation of an average propagation time value.
