Embodiment one
Fig. 2 is a kind of flow chart of the method for quality of optical fiber link monitoring that the embodiment of the present invention one provides.The present embodiment
The method of the quality of optical fiber link monitoring of offer to exchanging each optical fiber link route network suitable for being monitored with pre- in advance
Prevent the situation of each optical fiber link exception.The method of quality of optical fiber link monitoring provided in this embodiment can be by quality of optical fiber link
The device of monitoring executes, which can be realized by software and/or hardware, and be integrated in monitoring server.Reference chart
2, this method includes：
The optical fiber link transmission link to be detected that S110, monitoring server control instruction server include into monitoring range
Monitoring instruction.
In the present embodiment, it is all route in the exchange route network being stored in monitoring range in the monitoring server
Information, and have the function of that data analysis and link monitoring instruction generate.Wherein, monitoring range can according to practical situation into
Row setting, such as routing density setting etc. is set or pressed by region, whole routing iinformations can be deposited in the form of route information table
Storage is in monitoring server.Described instruction server can be monitoring server and exchange connecing for data transmission between route network
Mouthful.
Further, monitoring server and commander server can be integrated in a physical equipment, can also be collected respectively
At in different physical equipments.Specific integrated selection can be set according to actual conditions.
Illustratively, whole routing iinformations in monitoring server reading monitoring range in exchange route network, and according to
The routing iinformation generates the link monitoring instruction of each optical fiber link.Wherein, a routing may include at least one optical fiber chain
Road, there are two node device, each node devices at least to be connect with two optical fiber links for every optical fiber link.The node device
The data of transmission can be analyzed and be handled, has ensured on correct optical fiber link accurately to transmit transmission data.
Further, when exchange route network is made of optical fiber link, quality of optical fiber link can be by optical fiber link
The dough softening weigh.The dough softening of wherein optical fiber link is referred to as light decay value, light decay value optical fiber chain in a certain range
The normal transmission datas of Lu Caihui.In addition, quality of optical fiber link can also be by the number of the wrong data packet transmitted in optical fiber link
It measures to weigh.When the quantity of the wrong data packet transmitted in optical fiber link is more than certain value, illustrate that optical fiber link may occur
Exception cannot normal transmission data.Therefore, the link monitoring instruction is to monitor the mistake transmitted in optical fiber link to be detected
The instruction of data packet number and/or the light decay value in monitoring optical fiber link to be detected.

By switching so that the routing after switching does not include the optical fiber link to be detected.
Further, monitoring server can include institute to setting alarm platform transmission while sending switching command
State the warning information for the optical fiber link to be detected for meeting the first switching condition.Wherein, it includes described to be sent to setting alarm platform
It includes meeting the first report to meet the warning information of the optical fiber link to be detected of the first switching condition and sent to setting alarm platform
The execution method of the warning information of the optical fiber link to be detected of alert condition is identical.
Further, transmission route can be switched back into original transmission number by administrative staff manually after repairing optical fiber link
According to routing.
S636, interval setting processing frequency return to execution monitoring server control instruction server and are wrapped into monitoring range
The optical fiber link transmission link to be detected monitoring instruction included.
Further, when the link monitoring result of monitoring server analysis feedback is discontented with the first switching condition, explanation is worked as
Preceding quality of optical fiber link to be detected is good.At this point, monitoring server only need to continue to execute control according to the processing frequency of interval setting
The operation for the optical fiber link transmission link to be detected monitoring instruction that commander server processed includes into monitoring range.
The method for the quality of optical fiber link monitoring that the embodiment of the present invention three provides, is serviced by monitoring server control instruction
After each optical fiber link transmission link monitoring instruction to be detected of the device into monitoring range, receives and analyze the optical fiber chain to be detected
Roadbed in the link monitoring instruction feedback link monitoring as a result, and corresponding processing strategy is determined according to analysis result, can
With more accurately detection fiber link-quality, corresponding processing strategy is determined according to analysis result, optical fiber chain can be prevented in advance
The situation of road exception avoids being analyzed and repaired the influence caused by data normal communication after optical fiber link exception.
