With the rapid development of optical transport network OTN, it is increasingly important to implement an optical cable splicing technology for connecting a newly-built and newly-built optical cable transmission line with an existing optical transport network. The optical fiber fusion is a key link of optical cable cutting operation, and if the fiber cores are in error correspondence, namely in wrong fiber connection, the fiber cores can not receive light or light of other fiber cores directly.
In the prior art, a path tracking mark TTI detection mode is generally adopted, and whether the optical cable between the source end equipment and the sink end equipment is in wrong fiber connection is judged by judging whether the source end identifier received by the sink end equipment is an receivable identifier. However, this approach does not discover the wrong fiber connection until after a disruption in traffic occurs, and cannot accurately determine which network node the wrong fiber occurs between.
Based on the technical problems, the technical conception process of the application is as follows: how to find out the wrong fiber connection in time and accurately position the position of the wrong fiber connection.
The fault handling scheme of the optical cable misclassification connection of the present application is described in detail below.
Fig. 1 is a block diagram of an OTN network system provided in the present application, and as shown in fig. 1, the OTN network system may include: a server 11, a transport OTN network management 12 and an OTN network 13. Wherein the OTN network 13 comprises a plurality of OTN network nodes.
The server 11 initiates a connection information query request to the transmitting OTN network manager 12. The transmission OTN network manager 12 may obtain connection status information of the OTN network node in the OTN network 13 and the OTN network node adjacent thereto. The network node identifier is carried in a connection information query request initiated by the server 11 to the OTN network manager 12. The OTN network manager 12 obtains connection status information between the OTN network node corresponding to the network node identifier and the OTN network node adjacent thereto in response to the connection information query request, and returns the connection status information to the server 11.
The server 11 acquires connection status information between the OTN network node returned by the transmission OTN network manager 12 and the adjacent OTN network node, inquires about preset connection information between the locally stored OTN network node and the adjacent OTN network node, determines that an optical cable between the OTN network node and the adjacent OTN network node has a wrong fiber connection fault when determining that the connection status information is inconsistent with the preset connection information, and sends out alarm information that the optical cable has wrong fiber connection.
The following describes the technical scheme of the present application in detail through specific embodiments. It should be noted that the following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flow chart of a first embodiment of a fault handling method for optical cable fault fiber connection provided in the present application. Referring to fig. 2, the fault handling method for the optical cable misclassification connection specifically includes the following steps:
step S201: and initiating a connection information inquiry request to the transmission OTN network manager, wherein the connection information inquiry request carries a network node identifier so that the transmission OTN network manager can respond to the connection information inquiry request to acquire the connection state information between the OTN network node corresponding to the network node identifier and the adjacent OTN network node.
In this embodiment, the server initiates a connection information query request to the OTN network manager, where the connection information query request carries the network node identifier. The OTN network manager responds to the connection information inquiry request, acquires the connection state information between the OTN network node corresponding to the network node identifier and the OTN network node adjacent to the OTN network node, and returns the connection state information to the server.
The server initiates a connection information query request to the OTN network manager, where the network node identifier carried by the connection information query request corresponds to the OTN network node a. The transmission OTN network manager obtains connection state information, such as 'A-D', between the OTN network node A and the adjacent OTN network nodes, and represents that the OTN network node A is connected with the OTN network node D.
Specifically, the transmitting OTN network manager acquires connection status information between the OTN network node and its neighboring OTN network node by acquiring an optical supervisory signal in an optical supervisory channel (Optical Supervisory Channel, abbreviated as OSC). The optical supervisory channel is a single-core bi-directional channel. The optical monitoring signal is a bidirectional optical signal, and is combined with and separated from the service optical signal through the monitoring service optical multiplexer/demultiplexer (FIU).
Fig. 3 is a schematic diagram of combining and dividing the optical supervisory signals and the service optical signals. As shown in fig. 3, the service optical signal is unidirectional, the optical supervisory signal received from the service optical multiplexer/demultiplexer D40 on the left side and the optical supervisory signal sent from the optical supervisory board OSU on the left side are synthesized into one optical signal, and then output into the line fiber core, after reaching the optical supervisory signal on the right side, the optical supervisory signal is separated from the service optical signal in the line fiber core by the optical supervisory signal on the right side, the separated optical supervisory signal is sent to the OSU on the right side, and the service optical signal is sent to the optical multiplexer/demultiplexer M40 on the right side.
The optical supervisory signals illustratively employ an OTN frame structure with 4 x 4080 bytes per frame. The optical monitoring signal is converted into an electric signal through a photoelectric conversion module, and the electric signal is decoded through a forward error correction code (Forward Error Correction, abbreviated as FEC) to extract monitoring information. The monitoring information includes frame alignment, forward Error Correction (FEC) and data communication network (Data Communication Network, DCN) bytes, and the D1-D12 DCC channels are transmitted for operation, management, maintenance functions and optical layer characteristic overhead. The connection state information between the OTN network nodes can be obtained from the optical layer characteristic overhead, and the detection of the connection state between the OTN network nodes is realized.
Step S202: inquiring preset connection information between the OTN network node and the adjacent OTN network node, when the connection state information returned by the transmission OTN network manager is inconsistent with the preset connection information, determining that an optical cable between the OTN network node and the adjacent OTN network node has a wrong fiber connection fault, and generating and sending alarm information that the optical cable has wrong fiber connection.
In this embodiment, the server locally stores preset connection information between the OTN network node and its neighboring OTN network node. The preset connection information between the OTN network node a and its neighboring OTN network node is "a-B", which means that the OTN network node a should be connected to the OTN network node B, and is inconsistent with the connection status information "a-D" between the OTN network node a returned by the transmitting OTN network manager and its neighboring OTN network node. And when the connection state information is inconsistent with the preset connection information, determining that the optical cable between the OTN network node A and the adjacent OTN network node B has a wrong fiber connection fault. Illustratively, the server generates and transmits an alert message "there is a fiber-optic connection in error for the optical cable between OTN network node a and OTN network node B.
In this embodiment, the OTN network node may be an optical termination multiplexer (Optical Termination Multiplexer, abbreviated as OTM) node, or may be an optical amplifier (Optical Amplifier, abbreviated as OA) node. Fig. 4 is a schematic diagram of connection of an OTN network node in an OTN network. As shown in fig. 4, the OTN network node a and the OTN network node C are both OTM nodes, and the OTN network node B is an OA node.
In the prior art, whether the optical cable between the host equipment and the host equipment is connected by wrong fibers or not is judged by a TTI detection mode, and the source equipment and the host equipment are OTM nodes. In other words, by adopting the TTI detection method, only the optical cable between the OTN network node a and the OTN network node C is able to be judged to have a wrong fiber connection, and it is not possible to accurately determine whether the wrong fiber connection occurs between the OTN network node a and the OTN network node B or between the OTN network node B and the OTN network node C.
In this embodiment, by acquiring the connection status information "a-D" between the OTN network node a and its neighboring OTN network node, and querying the preset connection information between the locally stored OTN network node a and its neighboring OTN network node as "a-B", it is possible to accurately locate that the wrong fiber connection occurs between the OTN network node a and the OTN network node B.
In this embodiment, a connection information query request is initiated to a transmitting OTN network manager, where the connection information query request carries a network node identifier, so that the transmitting OTN network manager responds to the connection information query request to obtain connection state information between an OTN network node corresponding to the network node identifier and an OTN network node adjacent to the OTN network node; inquiring preset connection information between the OTN network node and the adjacent OTN network node, when the connection state information returned by the transmission OTN network manager is inconsistent with the preset connection information, determining that an optical cable between the OTN network node and the adjacent OTN network node has a wrong fiber connection fault, and generating and sending alarm information that the optical cable has wrong fiber connection. Compared with the prior art that the transmission OTN network management system adopts a TTI detection mode to detect the wrong fiber connection after the service interruption fault occurs, and the position of the wrong fiber connection cannot be accurately determined, the connection state information between the OTN network node and the adjacent OTN network node is acquired from the transmission OTN network management system, and compared with the locally stored OTN network node and the preset connection information between the OTN network node and the adjacent OTN network node, when the connection state information is determined to be inconsistent with the preset connection information, the optical cable between the OTN network node and the adjacent OTN network node is determined to have the wrong fiber connection fault and send out alarm information, the wrong fiber connection can be found in time before the service interruption fault occurs, and the position of the wrong fiber connection between the two adjacent network nodes can be accurately located, so that the problem that the optical fiber detection mode in the prior art cannot be found in time and the wrong fiber connection can be accurately located is solved.
Fig. 5 is a schematic flow chart of a second embodiment of a fault handling method for optical cable misclassification, which is provided in the present application, and referring to fig. 5, based on the embodiment shown in fig. 2, the fault handling method for optical cable misclassification specifically includes the following steps:
step S501: and initiating a connection information inquiry request to the transmission OTN network manager, wherein the connection information inquiry request carries a network node identifier so that the transmission OTN network manager can respond to the connection information inquiry request to acquire the connection state information between the OTN network node corresponding to the network node identifier and the adjacent OTN network node.
The connection state information comprises connection state information of the main optical fiber channel and connection state information of the standby optical fiber channel.
In this embodiment, the fibre channel between OTN network nodes includes a primary fibre channel and a backup fibre channel. Illustratively, the fibre channel between an OTN network node A and an adjacent OTN network node B includes a primary fibre channel A1-B1 and a backup fibre channel A2-B2.
In an OTN network, optical line protection may be implemented by an optical fiber line automatic switching protection device (Optical Fiber Line Auto Switch Protection, abbreviated as OLP). Specifically, the OLP comprises an optical switch and an optical power detection module, optical signals in a main optical fiber channel and a standby optical fiber channel respectively enter the optical switch, and the optical switch selects one optical fiber channel according to the optical power of the main optical signal and the standby optical signal acquired by the optical power detection module to realize communication. When the optical power of the optical signals in the main optical fiber channel and the standby optical fiber channel is changed and reaches the switching threshold, the optical switch can also realize the switching between the main optical fiber channel and the standby optical fiber channel.
In this embodiment, the connection status information between the OTN network node and its neighboring OTN network node, which is obtained from the transmission OTN network management, includes connection status information of the primary optical fiber channel and connection status information of the backup optical fiber channel between the OTN network node and its neighboring OTN network node.
Step S502: inquiring preset connection information between the OTN network node and an adjacent OTN network node, and determining that an optical cable between the OTN network node and the adjacent OTN network node has a wrong fiber connection fault and generating and sending alarm information that the optical cable has wrong fiber connection when determining that the connection state information of the main optical fiber channel returned by the transmission OTN network manager is inconsistent with the preset connection information of the main optical fiber channel and/or the connection state information of the standby optical fiber channel is inconsistent with the preset connection information of the standby optical fiber channel.
In this embodiment, the wrong fiber connection of the optical fibers may occur in the main fiber channel or in the spare fiber channel.
Illustratively, the primary fibre channel between the OTN network node a and its neighboring OTN network node B is in a connected state, and the backup fibre channel is in a disconnected state. The connection state information of the main optical fiber channel between the OTN network node A and the adjacent OTN network node obtained by the server from the transmission OTN network management is A1-B1, and the connection state information of the standby optical fiber channel is A2-C1.
Inquiring that preset connection information of a locally stored OTN network node A and a main optical fiber channel between the OTN network node A and an adjacent OTN network node is A1-B1, and preset connection information of a standby optical fiber channel is A2-B2.
As can be seen, if the connection status information of the spare fiber channel between the OTN network node a and the adjacent OTN network node is inconsistent with the preset connection information, it is determined that the optical cable between the OTN network node a and the adjacent OTN network node has a fault fiber connection, and the fault fiber connection occurs in the spare fiber channel, so as to generate and send alarm information that the optical cable between the OTN network node a and the adjacent OTN network node B has a fault fiber connection. Therefore, before the switching of the main optical fiber channel and the standby optical fiber channel between the OTN network node A and the adjacent OTN network node B, the alarm can be sent out in advance for the wrong optical fiber connection in the standby optical fiber channel, and the service interruption fault is avoided after the switching to the standby optical fiber channel.
In this embodiment, by acquiring connection status information of the main optical fiber channel and connection status information of the spare optical fiber channel between the OTN network node and its neighboring OTN network node, comparing the connection status information with preset connection information between the locally stored OTN network node and its neighboring OTN network node, and determining that an optical cable between the OTN network node and the neighboring OTN network node has a wrong optical fiber connection fault when determining that the connection status information of the main optical fiber channel is inconsistent with the preset connection information and/or the connection status information of the spare optical fiber channel is inconsistent with the preset connection information, the wrong optical fiber connection can be found in time before a service interruption fault occurs, and the wrong optical fiber connection can be accurately located in the main optical fiber channel and/or the spare optical fiber channel, which further solves the problem that the optical fiber detection mode in the prior art cannot find the wrong optical fiber connection in time and accurately locates the wrong optical fiber position.
