Description
Technical Field
The invention relates to the technical field of network security, in particular to a fault diagnosis system based on optical fiber communication.
Background
The specificity of the optical transmission network determines that the optical transmission line and the optical transmission device must have extremely high reliability, and the guarantee work of the optical transmission network gradually becomes the work core of operators at all levels. However, in the existing network, the stability of the transmission network is seriously affected by fiber damage, line interruption, equipment power failure, board card failure and the like. And great pressure is caused to clients, self benefits and line maintenance. Reinforcing the guarantee has been an urgent issue.
The optical bypass has a protection switching function, and the optical switch is the optical bypass and is generally used for recovering the network from faults. When the optical fiber breaks or other transmission faults occur, the optical switch is utilized to realize signal detour route, and the optical switch is switched from an access state to a bypass state, so that the purpose of bypass protection is achieved. The conventional optical bypass device has two states, namely an access state, which can be connected with access equipment in series to achieve the purpose of connecting the protected equipment in series, and a bypass state, which can bypass the access equipment and ensure the normal connection of the original link. The switching state is only a power-down bypass or a fiber-breaking bypass. The optical bypass has two main disadvantages: (1) Only two states are switched, and no intermediate state exists, so that maintenance is not facilitated; (2) And the line monitoring is absent, only the optical power monitoring of the protected side is supported, and the power change condition of the original link cannot be confirmed.

Further, the first PORT and the second PORT are integrated inside the protected device.
The fault diagnosis system based on optical fiber communication has three working modes.
First mode of operation: in the state of the optical switch being powered off, as shown in fig. 1, the first optical splitter and the second optical splitter are passive devices, so that in the power-off mode of the optical switch, the first optical splitter can be used for performing optical splitting processing on the received first optical signal to form a first sub-optical splitting first signal and a first sub-optical splitting second signal; the second optical splitter may be configured to perform optical splitting on the received second optical signal to form a second sub-split first signal and a second sub-split second signal.
Because the optical switch is in the power-off mode, the optical switch does not have a bypass function, at this time, the first optical signal acquired by the first receiving port R1 forms a first sub-split first signal and a first sub-split second signal through the first optical splitter, where the first sub-split first signal is reflected by the first optical splitter to the first WAN port module, and the first sub-split second signal is transmitted to the second transmitting port through the first optical splitter, and is transmitted and received by the second transmitting port T2 to be transmitted to the core switching device by the main link. And similarly, the second optical signal acquired by the second receiving port R2 forms a second sub-split first signal and a second sub-split second signal through the first optical splitter, wherein the second sub-split first signal is reflected to the second WAN port module through the second optical splitter, the second sub-split second signal is transmitted to the first transmitting port T1 through the second optical splitter, and the first transmitting port T1 transmits and receives a main link to be transmitted to the network element side switching equipment.
The first WAN port module and the second WAN port module are connected with the exchange chip, the exchange chip exchange signals connected with the first WAN port module perform flow statistics processing on first sub-beam splitting first signals acquired by the first WAN port module, and meanwhile, the exchange chip exchange signals connected with the second WAN port module perform flow statistics processing on second sub-beam splitting first signals acquired by the second WAN port module, and whether main link packet loss and packet error events occur is confirmed through flow statistics of the first sub-beam splitting first signals and the second sub-beam splitting first signals.
Second mode of operation: the bypass function can be realized by energizing the optical switch. As shown in fig. 2, the first optical splitter may be configured to perform optical splitting on the received first optical signal to form a first sub-split first signal and a first sub-split second signal; the second optical splitter may be configured to perform optical splitting on the received second optical signal to form a second sub-split first signal and a second sub-split second signal.
Because the optical switch is in the power-on mode, the optical switch has a bypass function, at this time, a first optical signal obtained by the first receiving port R1 forms a first sub-split first signal and a first sub-split second signal through the first optical splitter, the first sub-split first signal is reflected to the first WAN port module through the first optical splitter, the first WAN port module and the second WAN port module inside the optical switch are both in a working state, the first sub-split first signal (i.e., main link transmission data) enters the first WAN port module, the first WAN port module performs mirror image processing on the first sub-split first signal to form a first sub-split first mirror image signal, the first sub-split first mirror image signal is transmitted to the first LAN port module, meanwhile, the first sub-split first signal is transmitted to the second WAN port module through the internal conversion, and the second WAN port module transmits the first sub-split first signal to the core switching device through the second transmitting port. Similarly, the second optical signal is transmitted from the second receiving port to the first transmitting port through the above procedure.
The first WAN port module and the second WAN port module are connected with the exchange chip, the exchange chip exchange signals connected with the first WAN port module perform flow statistics processing on first sub-beam splitting first signals acquired by the first WAN port module, and meanwhile, the exchange chip exchange signals connected with the second WAN port module perform flow statistics processing on second sub-beam splitting first signals acquired by the second WAN port module, and whether main link packet loss and packet error events occur is confirmed through flow statistics of the first sub-beam splitting first signals and the second sub-beam splitting first signals. Meanwhile, the first LAN port module and the second LAN port module are connected with the exchange chip, the exchange chip exchange signals connected with the first LAN port module are subjected to flow statistics processing through the first sub-beam splitting first image signals acquired by the first LAN port module, meanwhile, the exchange chip exchange signals connected with the second LAN port module are subjected to flow statistics processing through the second sub-beam splitting first image signals acquired by the second LAN port module, and whether the first WAN port module and the second WAN port module are abnormal or not is confirmed through the flow statistics of the first sub-beam splitting first image signals and the second sub-beam splitting first image signals, for example, the flow statistics of the first sub-beam splitting first signals is inconsistent with the flow statistics of the first sub-beam splitting first image signals, and the first WAN port module is judged to be abnormal. And similarly, if the flow statistics of the second sub-beam splitting first signal is inconsistent with the flow statistics of the second sub-beam splitting first mirror image signal, judging that the second WAN port module is abnormal.
Third mode of operation: the bypass function can be realized by energizing the optical switch. As shown in fig. 3, the first optical splitter may be configured to perform optical splitting on the received first optical signal to form a first sub-split first signal and a first sub-split second signal; the second optical splitter may be configured to perform optical splitting on the received second optical signal to form a second sub-split first signal and a second sub-split second signal.
Because the optical switch is in the power-on mode, the optical switch has a bypass function, at this time, the first optical signal obtained by the first receiving PORT R1 forms a first sub-optical first signal and a first sub-optical second signal through the first optical splitter, the first sub-optical first signal is reflected to the first WAN PORT module through the first optical splitter, the first WAN PORT module and the second WAN PORT module inside the optical switch are both in a working state, the first sub-optical first signal (i.e. main link data transmission) further goes on the first WAN PORT module, the first sub-optical first signal is transmitted to the first LAN PORT module, and because the first LAN PORT module is cross-connected with the first PORT module, the first sub-optical first signal is transmitted to the first PORT module and is forwarded to the second PORT module through the first PORT module, the second PORT module transmits the first sub-optical first signal to the second LAN PORT module, the second LAN PORT module continues to transmit the first sub-optical first signal to the first WAN PORT module, and the second sub-optical first signal is transmitted to the first WAN PORT module through the first PORT. Similarly, the second optical signal is transmitted from the second receiving port to the first transmitting port through the above procedure.
It should be noted that, the first PORT module and the second PORT module are both built in the protected device, and in the third working mode, the protected device is completely connected in series to the data transmission link.
The first WAN port module and the second WAN port module are connected with the exchange chip, the exchange chip exchange signals connected with the first WAN port module perform flow statistics processing on first sub-beam splitting first signals acquired by the first WAN port module, and meanwhile, the exchange chip exchange signals connected with the second WAN port module perform flow statistics processing on second sub-beam splitting first signals acquired by the second WAN port module, and whether main link packet loss and packet error events occur is confirmed through flow statistics of the first sub-beam splitting first signals and the second sub-beam splitting first signals. Meanwhile, the first LAN port module and the second LAN port module are connected with the exchange chip, the exchange chip exchange signals connected with the first LAN port module are subjected to flow statistics processing through the first sub-beam splitting first image signals acquired by the first LAN port module, meanwhile, the exchange chip exchange signals connected with the second LAN port module are subjected to flow statistics processing through the second sub-beam splitting first image signals acquired by the second LAN port module, and whether the first WAN port module and the second WAN port module are abnormal or not is confirmed through the flow statistics of the first sub-beam splitting first image signals and the second sub-beam splitting first image signals, for example, the flow statistics of the first sub-beam splitting first signals is inconsistent with the flow statistics of the first sub-beam splitting first image signals, and the first WAN port module is judged to be abnormal. And similarly, if the flow statistics of the second sub-beam splitting first signal is inconsistent with the flow statistics of the second sub-beam splitting first mirror image signal, judging that the second WAN port module is abnormal. In addition, the protected equipment is internally provided with a heartbeat mechanism in the data transmission link, heartbeat data or heartbeat abnormal data formed by the heartbeat mechanism is sent to the optical switch (optical bypass equipment) according to a corresponding protocol, when the optical bypass equipment receives abnormal heartbeat data (the abnormal heartbeat data can be abnormal without receiving the heartbeat data or the abnormal heartbeat data), the current protected equipment can be judged to be in an abnormal state, and at the moment, the current work protection needs to be started to be switched to ensure the transmission of main link data. For example, the current third operating mode is switched to the first operating mode or the second operating mode. The LAN port module may be failed or the protected equipment may be failed when abnormal data is formed, but it may be determined that the WAN port module is not failed, and at this time, the link transmission mode is switched to the first working mode or the second working mode, so that the transmission of the main link is not damaged.
It should be noted that: when the third working mode is switched to the second working mode, the optical switch is not switched, namely the connection between the port of the core equipment and the WAN port module is not interrupted, and the switching to the second working mode does not influence the state change of the main link, so that the switching service loss can be achieved without perception switching.
As a further preferred embodiment, the above example further includes a first TAP port module that receives the optical split signal output from the first optical splitter and a second TAP port module that receives the optical split signal output from the second optical splitter. The TAP port module is connected with an external monitoring device to monitor whether a signal of the main link has a fault or abnormality.
In the first working mode, the optical switch Guan Liantong includes a first transmitting port, a first receiving port, a second transmitting port and a second receiving port, so that the first sub-split first signal and the first sub-split second signal formed by the first optical splitter are reflected to the first WAN port module by the first optical splitter, and the ratio of the split first sub-split first signal is relatively smaller.
In the second working mode or the third working mode, the optical switch Guan Liantong comprises a first transmitting port and a first WAN port module, a second transmitting port and a second WAN port module, a first receiving port and a first WAN port module, a second receiving port and a second WAN port module, wherein the first sub-split first signal formed by the first optical splitter and the first sub-split second signal are reflected to the first WAN port module through the first optical splitter, and the proportion of the split first sub-split first signal is relatively large.
