    • A method for realizing timing source synchronization is disclosed, applied to a ring-network including several network nodes wherein each network node selects a timing source from timing sources available for selection according to the quality states of the timing source, synchronizes the timing source, and takes the timing source as an available timing source for other network nodes; when the synchronized timing source is from a network interface, sets the timing source quality state to be sent to the network interface as non-synchronous source state, and sets the timing source quality state to be sent to all the other connected network interfaces as the quality state of the synchronized timing source; otherwise, sets the timing source quality state to be sent to all connected network interfaces as the quality state of the synchronized timing source. By the method, automatic selection and APS of timing source in networks can be realized.
    • 公开了一种用于实现定时源同步的方法,其应用于包括几个网络节点的环网,其中每个网络节点根据定时源的质量状态从可用于选择的定时源中选择定时源,同步定时源和 将定时源作为其他网络节点的可用定时源; 当同步定时源来自网络接口时,将要发送到网络接口的定时源质量状态设置为非同步源状态,并将定时源质量状态设置为发送到所有其他连接的网络接口,作为 同步定时源的质量状态; 否则,将定时源质量状态设置为发送到所有连接的网络接口作为同步定时源的质量状态。 通过该方法,可以实现网络中定时源的自动选择和APS。
