    • Method, system and node for providing time synchronisation between local clocks located in nodes within a network and a central clock. The central clock and the nodes exchange messages. The messages transmitted contain a time stamp indicating the time of transmission. When messages are received, the time of reception is also determined. Based upon the calculation of the elapsed time taken by messages to be transmitted and received, a time difference can be estimated which indicates how much the clock on a node lags behind the central clock. Once this lag is known, the clock on the node can be updated. The proposed invention allows for a more precise time synchronisation to take place between nodes and a central clock without having to perform modifications on the transport circuitry of the system. The invention also allows for any changes in the network topology to be detected via any changes in the Round Trip Time, and a management centre to be notified in turn. Additionally, the invention allows for statistical information to be gathered in order to determine the quality of the synchronisation procedure.
    • 用于在位于网络内的节点和中央时钟之间的本地时钟之间提供时间同步的方法,系统和节点。 中央时钟和节点交换消息。 发送的消息包含指示传输时间的时间戳。 当接收到消息时,接收的时间也被确定。 基于要发送和接收的消息所花费的时间的计算,可以估计时间差,其指示节点上的时钟滞后于中央时钟的时间。 一旦知道这个滞后,就可以更新节点上的时钟。 所提出的发明允许在节点和中央时钟之间进行更精确的时间同步,而不必对系统的传输电路进行修改。 本发明还允许通过往返时间中的任何改变来检测网络拓扑中的任何变化,以及依次通知的管理中心。 另外,本发明允许收集统计信息以便确定同步过程的质量。
