分散された同期方法及びシステム
Document Type and Number:
Japanese Patent JP2008501262
Kind Code:
A
Abstract:
A distributed synchronization method in a communication network is disclosed. A number of stations exchange messages between themselves. A synchronization pattern characteristic of the clock reference of the sender is inserted into each message transmitted by a sender. The clock reference of each station is updated with the clock reference that it receives from another station of the network if, and only if, the received time is leading the clock reference. The update is done by calculating the difference ΔX=T′a−Ta between the time of sending T′a of the message received by a station A and the time of reception Ta of the same message by the station B, and applying a correction 0<ΔY<=ΔX if the received time of sending is leading by a quantity of at least τ (ΔX>τ>0).
