Fig. 7 is that as shown in Figure 7, this method can comprise that step S702 is to step S712 according to the flow chart of place, the clock source machine frame hand-off process of the embodiment of the invention.
Step S702, place, clock source machine frame switches.
Before step S702, can select place, cascade system clock source machine frame is the time service machine frame, and other machine frame is by the time service machine frame; Set the time service machine frame and be operated in the OC pattern of PTP, time synchronized message frequency by the time service machine frame; Selection is by the time service main port with by the time service standby port, PTP master mouth and slave mouth; Start PTP and synchronous ethernet function and stride the machine frame time synchronized; Handle incidents such as cascade port down and the switching of clock source.
Step S704 resets the time service machine frame and is operated in the OC pattern of PTP by the time service machine frame.
Step S706 reselects by the time service main port with by the time service standby port PTP master mouth and slave mouth.
Step S708, the setting-up time synchronizing frequency is that two-forty is synchronous.
Step S710 starts PTP and synchronous ethernet function and strides the machine frame time synchronized.
Step S712, it is original in low value setting the sync message frequency after a period of time synchronously.
From above description; Can find out; The present invention has realized following technique effect: the time service machine frame is received the information that the time service machine frame sends by the time service machine frame, and from this information, obtains the temporal information of time service machine frame and/or the frequency information of time service machine frame through being sent information by the communication link alignment between time service machine frame and the time service machine frame by the time service machine frame; Under the situation that the hardware that does not increase between the machine frame connects, realized striding the transparent transmission of time and frequency in the frame device.Further, send information according to higher frequency, after time synchronized surpasses Preset Time, send information, thereby reduced taking cpu resource according to lower frequency in the time synchronized incipient stage.
