Specific embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing to this
Bright be described in further detail it is clear that described embodiment is only present invention some embodiments,
Rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
The all other embodiment being obtained under the premise of going out creative work, broadly falls into the scope of protection of the invention.
In order to realize that the synchronous path of the device node in synchronizing network is detected, a kind of mode is by skill
Art personnel plan the position of synchronous source node according to the topological structure of communication network, but due to not entering one
The means of step accurate detection synchronous path jumping figure, so it is difficult to ensure that the jumping figure of synchronous path is without departing from related mark
The threshold value of quasi- regulation.The jumping figure of strict guarantee synchronous path without departing from threshold value, then needs to adopt people if necessary
Work mode node-by-node algorithm jumping figure, so not only amount of calculation greatly but also plans that time-consuming, and may introduce meter
Calculate error.
After synchronisation source node deployment, with the expansion of network size, the synchronous path jumping figure of device node also can
Change therewith.To synchronous path jumping figure is carried out with accurate detection, need, after each network capacity extension, to adopt
Manual type checks whether the jumping figure of device node exceeds threshold value.
The scale of synchronizing network is generally large, and the device node number for setting up synchronizing network can reach thousand of
Extremely up to ten thousand, the link in synchronizing network is intricate it is ensured that the jumping figure of the synchronous path of device node does not surpass
Go out threshold value, need the jumping figure of manual type node-by-node algorithm device node it can be seen that, either in synchronous net
The synchronous path detection at initial stage planned by network, or because the network capacity extension needs again after the completion of synchronizing network planning
Synchronize path detection, if all using manual type, can lead to that amount of calculation is big, complexity is high,
The problem that time-consuming, and it is easily introduced error.And the accuracy of the jumping figure detection of synchronous path, by shadow
Ring synchronizing network planning, and then affect the performance of device node.
In order to solve problem above, the application proposes a kind of synchronizing network detection method and device.
In embodiments of the present invention, the detection to the jumping figure of the synchronous path of device node, can be by synchronizing network
Detection means completes, and need not manually calculate, and shortens and reduce workload and the time of synchronizing network detection,
Meanwhile, detect the jumping figure of synchronous path of device node exceed threshold value after can send warning information so that
The in time optimized synchronization network planning, it is to avoid the synchronous path jumping figure of device node is excessive and affect synchronizing network

Or, for primary synchronous path, can be determined using aforesaid way B3, for standby synchronous path,
Can be determined using aforesaid way B1 or aforesaid way B2.
Certainly, as needed, also can only determine primary synchronous path, or only determine standby synchronous path.
Step 203：In detection synchronizing network, whether the jumping figure of the synchronous path of device node exceeds jumping figure threshold value,
If so, then proceed to step 204.
Further, if testing result be the jumping figure of synchronous path without departing from jumping figure threshold value, can be according to being
System sets one of following operation of execution：
- process ends；
- according to setting cycle, wait next detection cycle to reach；
- according to setting time, wait next detection time to reach；

Rapid 202 or step 201, otherwise can terminate flow process.
Wherein, described jumping figure threshold value can according in ITU-T, CCSA etc. both at home and abroad relevant criterion to synchronization
The related restriction of the jumping figure of equipment in network node to determine.In synchronizing network detection process, can be prior
Jumping figure threshold value is configured in synchronizing network detection means it is also possible to configuration in synchronizing network detection process
Jumping figure threshold value in synchronizing network detection means is adjusted.
The jumping figure of the synchronous path of device node in synchronizing network when being embodied as, can be detected in the following way
Whether exceed jumping figure threshold value：For each device node in device node synchronous path, detect each one by one
Whether the jumping figure at device node exceeds jumping figure threshold value.
For example, for primary synchronous path, can be for each the equipment section in the primary synchronous path of device node
Point, detects whether the jumping figure at each device node exceeds jumping figure threshold value one by one；For standby synchronous path,
Each standby synchronous path of device node can be respectively directed to, according to each equipment in this standby synchronous path
Node, detects whether the jumping figure at each device node exceeds jumping figure threshold value one by one.
Step 204：Jumping figure for synchronous path sends warning information beyond the device node of jumping figure threshold value.
Wherein, described warning information may include herein below：The mark of device node, jumping figure exceed jumping figure threshold
The mark of the synchronous path of value, further, may also include the jump that jumping figure exceedes the synchronous path of jumping figure threshold value
The information such as number.This warning information can be used as the foundation of follow-up optimized synchronization network.
Further, if the jumping figure synchronous path of the first device node is detected exceeds jumping figure threshold value, at this
Jumping figure exceeds in the synchronous path of jumping figure threshold value, starts to trace to the source to synchronisation source node direction from the first device node
The second device node being described jumping figure threshold value to jumping figure, and be emitted at the second device node to the first equipment
The information of synchronous source node is set up between node.Wherein, described first device node and described second sets
Slave node is simultaneously not specific to certain or some or certain kind equipment node, is only in description conveniently to make a distinction.
For example, if the jumping figure primary synchronous path of device node is detected exceeds jumping figure threshold value, for master
Exceed the device node of jumping figure threshold value with the jumping figure of synchronous path, exceed the master of jumping figure threshold value in this device node
With, in synchronous path, starting to be traceable to jumping figure to synchronisation source node direction from this device node is described jumping figure threshold
At the device node of value, and set up the prompting of synchronous source node between being emitted in above-mentioned two device node
Information.
Again for example, if the jumping figure standby synchronous path of device node is detected exceeds jumping figure threshold value, it is directed to
The jumping figure of standby synchronous path exceeds the device node of jumping figure threshold value, exceeds jumping figure threshold value in this device node
In standby synchronous path, starting to be traceable to jumping figure to synchronisation source node direction from this device node is described jumping figure
At the device node of threshold value, and set up the prompting of synchronous source node between being emitted in above-mentioned two device node
Information.
By above description as can be seen that the embodiment of the present invention can be realized to device node in synchronizing network
The jumping figure of synchronous path is detected, and because the synchronous path of the device node in synchronizing network is to be based on
The network topology structure of this synchronizing network gets, therefore, it is possible to ensure the accurate of synchronous path jumping figure detection
