[0044] The present disclosure is described below in conjunction with the accompanying drawings. The preferred embodiments described herein are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure.

[0045] Figure 1 The optical network monitoring method based on wavelength labels provided in the present disclosure includes:

[0046] Step 101: Generate wavelength labels for the source node and the sink node respectively;

[0047] Step 102: Send the wavelength label to the optical network interface disk, and construct reference label data based on the wavelength label; the optical network interface disk includes: the OCH interface disk of the source node and the sink node, the OA disk and the OPM disk in the service path; the reference label data includes: the corresponding relationship data between the wavelength label and the optical network node when the optical network is normal;

[0048] Step 103: Acquire current label data based on the wavelength label reported by the optical network device;

[0049] Step 104: Compare the reference tag data with the current tag data to determine the optical network status.

[0050] According to some embodiments of the present disclosure, the implementation process of the wavelength label-based optical network monitoring method proposed in the present disclosure is as follows:

[0051] 1. Create an OCH service on the network management system and activate it. After successful activation, generate globally unique wavelength label IDs for the source and sink nodes respectively, call the device wavelength label configuration interface, and set the source and sink node wavelength labels to the OCH interface disk respectively.

[0052] 2. The wavelength labels are transferred to all OA disks and OPM disks on the service path, and a wavelength label reference data table of a single disk related to the service is generated.

[0053] 3. After receiving the wavelength label issued by the network management system, the source and sink network element devices perform wavelength label modulation and distribute the wavelength label to the OA disk and OPM disk along the actual service routing direction. The devices report the wavelength label status data update to the network management system based on the port service wavelength label data demodulated by the OA disk and OPM disk.

[0054] 4. Receive the wavelength label change data reported by the device, update the stored device-side status data, and compare it with the service wavelength label benchmark data, generate fault information and store it (fault occurs) or update the stored fault information (fault disappears).

[0055] 5. Query OCH faults, transfer all OA and OPM disks on the OCH service route, query the wavelength label status of the relevant single disk, update the stored device side status data, and compare it with the service wavelength label benchmark data to generate fault information and feedback.

[0056] Furthermore, the wavelength label includes one or more of the following parameters:

[0057] Node parameters of the source node, node parameters of the sink node, rate, code type, center wavelength, center frequency and bandwidth; wherein the node parameters include:

[0058] NE ID, disk ID, and port.

[0059] According to some embodiments of the present disclosure, the wavelength label is composed of parameters such as the source node (network element id, single disk id, source port), the sink node (network element id, single disk id, sink port), rate, code type, central wavelength / frequency, bandwidth, etc. into a globally unique wavelength label ID. According to the source and sink node combination sequence, the wavelength labels of the source node and sink node of the same service are also different. Among them, the wavelength label allocation table represents the correspondence between the wavelength label ID and the source node (network element id, single disk id, source port), the sink node (network element id, single disk id, sink port), rate, code type, central wavelength / frequency, bandwidth, etc.

[0060] Furthermore, before respectively generating the wavelength labels of the source node and the sink node, the method further includes:

[0061] Determine whether the current service is an activated OCH service newly generated according to the switching event;

[0062] If yes, a wavelength label deletion command is sent to all nodes corresponding to the activated OCH service, so that they delete the existing wavelength labels.

[0063] According to some embodiments of the present disclosure, OCH service scenarios are divided into two types. For normally created and activated OCH services, a wavelength label is directly generated and sent to the device; for an activated OCH service newly generated according to a switching event, it is necessary to first delete the interface label of the original OCH service before the switching, and then generate a wavelength label and send it to the device. Figure 2 A wavelength label generation and configuration flow chart is shown, which includes:

[0064] Step 201: Select an activated OCH service and generate a source node wavelength label.

[0065] Step 202: configure the source node wavelength label to the OCH interface disk of the service source node.

[0066] Step 203: Generate a wavelength label for the OCH service sink node.

[0067] Step 204: configure the sink node wavelength label to the OCH interface disk of the service sink node.

[0068] Step 205: If the OCH service is deleted, a wavelength label deletion command needs to be sent to all nodes having the source and destination wavelength labels of this service.

[0069] based on Figure 2 The wavelength label generation and configuration method provided realizes the generation and configuration of wavelength labels on the network management side for the above two OCH service scenarios.

[0070] Further, obtaining current label data based on the wavelength label reported by the optical network device includes:

[0071] The wavelength label is modulated into the carrier by the source node or the sink node;

[0072] Optical network equipment in the service path is used to demodulate the carrier, receive the wavelength label, and report the current label data according to the wavelength label.

[0073] According to some embodiments of the present disclosure, Figure 3 As shown, the process of obtaining wavelength label data of an optical network device includes:

[0074] Step 301: After receiving the wavelength label sent by the network management, the source (or sink) network element device performs wavelength label subcarrier modulation.

[0075] Step 302: The OA disk and the OPM disk on the actual service route detect and parse the wavelength label subcarrier carried by the carrier wavelength.

[0076] Step 303: The device reports wavelength label status change data to the network management according to the port service wavelength label data demodulated by the OA disk and the OPM disk.

[0077] Further, comparing the reference tag data with the current tag data to determine the optical network state includes:

[0078] When it is determined that the target path lost port has other path wavelength labels, and other path single disks have target path wavelength labels, it is determined that the target path optical fiber is misconnected.

[0079] According to some embodiments of the present disclosure, Figure 4 As shown, after receiving the changed wavelength label reported by the device, the corresponding OCH service information is queried from the service wavelength label reference table, and each OA and OPM disk port on the OCH service route in the service wavelength label reference table is traversed. According to the device wavelength label status table, check whether the port has lost labels. For ports with lost labels, check whether there are other path wavelength labels for the lost port. For lost ports with other path wavelength labels, check whether the single disk on other paths has the label of this path. If so, it means that the optical fiber is misconnected, otherwise it means that the label is lost.

[0080] Further, comparing the reference tag data with the current tag data to determine the optical network state further includes:

[0081] When it is determined that the target path lost port has other path wavelength labels, and other path single disks do not have the target path wavelength label, it is determined that the target path wavelength label is lost; and

[0082] When it is determined that no other path wavelength labels exist at the target path loss port and no subsequent single disk has wavelength label loss at the same time, it is determined that the target path wavelength label is lost.

[0083] According to some embodiments of the present disclosure, Figure 4 As shown, for the lost port, there is no other path wavelength label. Check whether the single disk after the lost port has label loss. If not, it means that the label is lost.

[0084] Further, comparing the reference tag data with the current tag data to determine the optical network state further includes:

[0085] When it is determined that the target path loses the port and the subsequent disk has the wavelength label lost at the same time, and the disk with the lost label is not a VGA type disk, it is determined that the fiber connection of the target path is abnormal; and

[0086] When it is determined that the target path loses the port and the subsequent disk has the wavelength label lost at the same time, the disk that loses the label is a VGA type disk, and there is no OSC disk RLOS alarm associated with the VGA disk, it is determined that the target path fiber connection is abnormal.

[0087] According to some embodiments of the present disclosure, Figure 4As shown in the figure, the labels of all the disks after the port is lost are lost. Check whether the disk with the lost label is a VGA type disk. If not, it indicates that the fiber connection is abnormal.

[0088] Further, comparing the reference tag data with the current tag data to determine the optical network state further includes:

[0089] When it is determined that the wavelength label of the subsequent disk of the target path loss port is lost, the disk that loses the label is a VGA type disk, and an OSC disk RLOS alarm associated with the VGA disk exists, it is determined that the optical fiber of the target path is disconnected.

[0090] According to some embodiments of the present disclosure, Figure 4 As shown, in the case where the single disk with the lost label is a VGA type single disk, check whether there is an OSC type single disk associated with the VGA single disk and whether the OSC single disk has an RLOS alarm. If the OSC single disk exists and there is an RLOS alarm, it means that the optical fiber is disconnected, otherwise it means that the fiber connection is abnormal.

[0091] Based on the same technical concept, such as Figure 5 As shown, the present disclosure also proposes an optical network status monitoring system based on wavelength labels, comprising:

[0092] The label generation module 501 is used to generate wavelength labels of the source node and the sink node respectively;

[0094] The data acquisition module 503 is used to acquire the current label data based on the wavelength label reported by the optical network device;

[0095] The state determination module 504 is used to compare the reference label data with the current label data to determine the state of the optical network.

[0096] According to some embodiments of the present disclosure, the wavelength label configuration and status service provides an interface:

[0100] 4. Label status query interface: check service wavelength label benchmark data and equipment status data, check fault points, and generate reports.

When the computer program or instruction is executed by the processor 602, it is at least used to implement the above-mentioned wavelength label-based optical network monitoring method.
