Certainly, as needed, it also can only determine primary synchronous path, or only determine spare synchronous path.
Step 203：Whether the hop count for detecting the synchronous path of device node in synchronizing network exceeds hop count threshold value, if so,
Then it is transferred to step 204.
Further, if testing result be synchronous path hop count without departing from hop count threshold value, can be according to default
Execute one of following operation：
Terminate this flow；
According to the setting period, next detection cycle is waited for reach；
According to setting time, next detection time is waited for reach；
Judge whether the network topology structure of synchronizing network changes, if changing, can return to step
Rapid 202 or step 201, it otherwise can terminate flow.
Wherein, the hop count threshold value can be according to ITU-T, CCSA etc. both at home and abroad in relevant criterion to equipment in synchronizing network
The related of the hop count of node limits to determine.In synchronizing network detection process, can hop count threshold value be configured to synchronization in advance
It, can also be in synchronizing network detection process to configuring the hop count threshold value in synchronizing network detection device in network detection device
It is adjusted.
When it is implemented, whether the hop count that can be used as under type detects the synchronous path of device node in synchronizing network surpasses
Go out hop count threshold value：For each device node in device node synchronous path, the hop count at each device node is detected one by one
Whether hop count threshold value is exceeded.
For example, for primary synchronous path, each device node that can be directed in the primary synchronous path of device node, one by one
Detect whether the hop count at each device node exceeds hop count threshold value；For spare synchronous path, it can be directed to device node respectively
Each of spare synchronous path detected one by one at each device node according to each device node in the spare synchronous path
Hop count whether exceed hop count threshold value.
Step 204：Warning information is sent out for device node of the hop count beyond hop count threshold value of synchronous path.
Wherein, the warning information may include the following contents：The mark of device node, hop count are more than the synchronization of hop count threshold value
The mark in path further may also include hop count more than information such as the hop counts of synchronous path of hop count threshold value.The warning information
It can be used as the foundation of follow-up optimized synchronization network.
Further, if detecting, the hop count of the synchronous path of the first device node exceeds hop count threshold value, super in the hop count
Go out in the synchronous path of hop count threshold value, is the hop count since hop count is traceable to synchronisation source node direction the first device node
Second device node of threshold value, and be emitted at the second device node to adding carrying for synchronous source node between the first device node
Show information.Wherein, first device node and second device node and some or certain or certain class equipment section are not specific to
Point is distinguished in describing conveniently.
If for example, detecting that the hop count of the primary synchronous path of device node exceeds hop count threshold value, it is directed to primary synchronization
The hop count in path exceeds the device node of hop count threshold value, in primary synchronous path of the device node beyond hop count threshold value, from
The device node starts to be traceable to synchronisation source node direction at the device node that hop count is the hop count threshold value, and is emitted in
The prompt message of synchronous source node is added between two device nodes stated.
If for another example detecting that the hop count of the spare synchronous path of device node exceeds hop count threshold value, for spare same
The hop count of step diameter exceeds the device node of hop count threshold value, in spare synchronous path of the device node beyond hop count threshold value,
Since being traceable to synchronisation source node direction the device node at the device node that hop count is the hop count threshold value, and it is emitted in
The prompt message of synchronous source node is added between above-mentioned two device node.
By above description as can be seen that the same step to device node in synchronizing network may be implemented in the embodiment of the present invention
The hop count of diameter is detected, and since the synchronous path of the device node in synchronizing network is the network based on the synchronizing network
What topological structure was got, therefore can ensure the accuracy of synchronous path hop count detection.To equipment section in the embodiment of the present invention
The detection of the hop count of the synchronous path of point, can be completed by synchronizing network detection device, be calculated without artificial, shortened and reduced same
Walk workload and the time of network detection.In addition, the embodiment of the present invention is super in the hop count for the synchronous path for detecting device node
Warning information can be sent out after going out threshold value, so as to the timely optimized synchronization network planning, avoids the synchronous path hop count mistake of device node
Performance that is big and influencing synchronizing network.
