[0054] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0055] Optical Transport Network (OTN) is a type of network that implements the transmission, multiplexing, routing, and monitoring of service signals in the optical domain, and ensures their performance indicators and survivability. The OTN amplifier board is an important board that amplifies the optical power to ensure reliable signal output.

[0056] In order to solve the problem of the decline of the transmit and receive optical power performance indicators of the amplifier board caused by the natural aging of the OTN amplifier board equipment, optical cable splicing and other reasons during daily maintenance, it is necessary to monitor and warn the optical power of the OTN amplifier board. In related technologies, the nominal value of the optical power of the OTN amplifier board is manually maintained and calculated; the number of channels carried by the amplifier board is also manually scanned and calculated; the number of channels fully equipped in the wavelength division system is determined by manually querying the network management fiber connection information; the first-level amplifier board and the second-level amplifier board are determined by the network management standards / remarks. These manual tasks are large in workload, time-consuming, poor in accuracy, slow in update cycle and low in update frequency, resulting in the risk of low efficiency and low accuracy of the optical power warning of the OTN amplifier board.

[0057] To this end, an embodiment of the present invention provides an automatic early warning method for the optical power of an amplifier board. The automatic early warning method for the optical power of an amplifier board is based on an identifier of each amplifier board, extracts the actual optical power of each amplifier board from the configuration resource data and optical power performance data of the network management equipment in the optical transmission network OTN, and calculates the theoretical optical power of each amplifier board. The two are compared to obtain the optical power early warning information of the amplifier board, thereby improving the accuracy, authenticity and update rate of the optical power early warning data of the amplifier board. Through automated technology and methods, the problems of slow manual import and update and poor data accuracy are effectively solved, and the efficiency of automatic early warning and monitoring is improved.

[0058] The inventive concept of the present invention is further described below in conjunction with some specific embodiments.

[0059] The present invention provides a first embodiment of an automatic early warning method for optical power of an amplifier board. Figure 2 , Figure 2 It is a flow chart of the first embodiment of the automatic early warning method for optical power of an amplifier board of the present invention.

[0060] In this embodiment, an automatic early warning method for optical power of an amplifier board includes the following steps:

[0061] Step S101: Acquire configuration resource data and optical power performance data of a network management device in an optical transport network OTN.

[0062] Among them, all data of the same amplifier board in the configuration resource data and the optical power performance data have the same identifier.

[0063] In this step, the configuration resource data such as SNL (subnet connection data), SNT (subnet routing data), SNR (subnet bearer relationship data) on the OTN network management are collected through the standard interface reserved by the equipment manufacturer on the OTN equipment. At the same time, the optical power performance file of the OTN equipment is collected. The optical power performance file includes 18 resource files of the northbound interface specification and 6 optical power performance data. After the collection is completed, these data are parsed and stored in the database through the program. During the parsing, all configuration resource data and the data with the identifier in the optical power performance data can be parsed together through the identifier of each amplifier board, and the network elements, containers, boards, and ports in the OTN are constructed in the database, so as to obtain the actual construction information of the amplifier board and construct the optical transmission path of the amplifier board.

[0064] Step S102: pre-process the configuration resource data according to the identifier of each amplifier board in the OTN to obtain the actual channel number, theoretical channel number, saturated output data and gain data of each amplifier board.

[0065] The actual number of channels is the number of channels actually carried by each amplifier board in the OTN. The theoretical number of channels is the number of channels that the amplifier board should theoretically carry in the corresponding route, such as 80 channels or 40 channels. The saturated output data and gain data are both original data of the configuration resource data, which can be directly extracted from the 18 resource files of the northbound interface specification, and will not be described here.

[0066] In this step, the configuration resource data is preprocessed according to the identification of each amplifier board in the OTN, so that all the original data corresponding to the amplifier board can be extracted from the huge amount of original data of the configuration resource data, and then preprocessing such as extraction, screening and statistics are performed based on all the original data of the amplifier board to obtain the actual number of channels, theoretical number of channels, saturated output data and gain data of each amplifier board.

[0067] In a specific embodiment, the actual channel number, theoretical channel number, saturation output data and gain data can be obtained by the following methods. Figure 3 , that is, step S102 includes:

[0068] Step A10: Filter out the second routing data and the first routing data corresponding to the OCH layer data from the subnet routing data.

[0069] In OTN, SubNetwork includes network layers such as OTS (optical transmission segment network), OMS (optical multiplexing segment network), and OCH (optical channel layer network). In this embodiment, the second routing data corresponding to the OCH layer data and the first routing data corresponding to the OTS (optical transmission segment network) and OMS (optical multiplexing segment network) can be screened out from the configuration resource data. Before step A10, the OCH layer data and the service layer data can be determined by the following steps:

[0070] (1) Extract OCH layer data from SNL subnet connection data.

[0071] (2) Filter out service layer data from the SNR subnet bearer relationship data.

[0072] Service layer data includes OTS data and OMS data.

[0073] Step A20: According to the identifier of each amplifier board in the OTN, the number of occurrences of each amplifier board in the second routing data and the first routing data is counted to determine the actual number of channels of each amplifier board.

[0074] In this step, according to the identifier of each amplifier board in the first routing data and the second routing data, the number of occurrences of each amplifier board in the first routing data and the second routing data is counted. This number is the number of channels actually carried by the amplifier board, that is, the actual number of channels of each amplifier board.

[0075] In this step, compared with the manual scanning and manual calculation methods, which are prone to errors and slow to update, the automatic calculation of the actual channel number of the amplifier board has a higher accuracy rate. And the actual channel number of the amplifier board is determined by the number of times the amplifier board appears in the routing file, which can respond to the actual situation of network cutover upgrade adjustment in a timely manner and update faster.

[0076] Step A30: Count the number of comb filter boards in each route in the first route data to determine the theoretical number of channels carried by the amplifier board in each route.

[0077] Specifically, it is judged by whether there is a comb filter board in the first routing data corresponding to the OMS and OTS. If there is a comb filter board, the theoretical number of wave channels carried by the amplifier board in the route is judged to be 80 waves. If there is no comb filter board, the theoretical number of wave channels carried by the amplifier board in the route is judged to be 40 waves.

[0078] In this step, compared with the technical problems of slow update and heavy workload in manually querying the network management fiber connection information, the theoretical channel number of the amplifier board is automatically determined by configuring whether there is a comb filter board in the resource data. The result is more accurate and updated faster.

[0079] Step A40: According to the identifier of each amplifier board in the OTN, the saturated output data and gain data of each amplifier board are extracted from the northbound interface specification resource data.

[0080] Since the saturated output data and gain data are both original data in the northbound interface specification resources, they can be extracted according to the identifier of each amplifier board in the OTN. Based on the same identifier, the actual number of channels, theoretical number of channels, saturated output data, and gain data of each amplifier board are associated together.

[0081] Step S103: According to the identifiers of the saturated output data and the gain data in the configuration resource data, optical power data with the same identifier is screened out from the optical power performance data to obtain the actual optical power of each amplifier board.

[0082] After obtaining the actual channel number, theoretical channel number, saturated output data and gain data of each amplifier board, the optical power data with the same identification can be extracted from the optical power performance data according to the identification of the amplifier board, thereby obtaining the actual optical power of each amplifier board. The actual optical power of each amplifier board includes the actual input optical power and the actual output optical power.

[0083] It is worth mentioning that when the configuration resource data is preprocessed, the optical power data can also be extracted according to the identifier, or the optical power data can be extracted first, and then the actual number of channels, theoretical number of channels, saturated output data, gain data, etc. This embodiment does not limit the order of these steps.

[0084] Step S104: Obtain theoretical optical power of each amplifier board according to the actual channel number, theoretical channel number, saturated output data and gain data.

[0085] The theoretical optical power is the nominal power of the amplifier board. Specifically, after obtaining data such as the actual number of channels and the theoretical number of channels, the theoretical optical power of the amplifier board can be calculated based on the corresponding formula.

[0086] As in one specific embodiment, see Figure 4 , step S104 includes the following steps:

[0087] Step B10: Obtain the single-wave standard output data of each amplifier board according to the saturated output data of each amplifier board and the theoretical number of channels.

[0088] Single-wave standard output data = saturated output data - 10log (theoretical channel number). Since the theoretical channel number is 40 or 80 waves,

[0089] Therefore, when the theoretical number of channels is 40, the single-wave standard output data = saturated output data - 16.

[0090] When the theoretical number of channels is 80, the single-wave standard output data = saturated output data - 19.

[0091] Step B20: Obtain the theoretical output optical power of each amplifier board according to the single-wave standard output data of each amplifier board and the actual number of carried channels.

[0092] The theoretical output optical power can be calculated based on the amplifier board commissioning formula. Specifically:

[0093] Theoretical output optical power = single-wave standard output + 10Llog (actual number of channels).

[0094] Step B30: Obtain the theoretical input optical power of each amplifier board according to the theoretical output optical power and gain data of each amplifier board.

[0095] After obtaining the theoretical output optical power, the theoretical input optical power of the amplifier board can be calculated by subtracting the gain data from the theoretical output optical power. That is, theoretical input optical power = theoretical output optical power - gain data

[0096] Step S105: Compare the actual optical power of each amplifier board with the theoretical optical power to obtain amplifier board optical power warning information.

[0097] After obtaining the actual input tube power, actual output optical power, and theoretical input optical power and theoretical output optical power of each amplifier board, unqualified amplifier boards can be identified by comparison, thereby obtaining a list of unqualified amplifier boards, i.e., amplifier board optical power warning information.

[0098] Specifically, see Figure 5 , step S105 may include:

[0099] Step C10: Compare the actual optical power of each amplifier board with the theoretical optical power to determine whether the difference between the actual optical power and the theoretical optical power is less than or equal to a preset threshold.

[0100] Step C20: Mark the amplifier board corresponding to the difference greater than the preset threshold as an unqualified amplifier board.

[0101] Step C30: output all unqualified amplifier boards to form amplifier board optical power warning information.

[0102] The preset threshold can be set according to specific circumstances, and this embodiment does not limit this. For example, the preset threshold can be 2db. After comparison, the amplifier boards with a difference greater than 2db after comparison can be marked to form a list of unqualified amplifier boards, and the list is output, which is also the amplifier board optical power warning information.

[0103] This embodiment provides an automatic early warning method for the optical power of an amplifier board. Based on the identification of each amplifier board, the actual optical power of each amplifier board is extracted from the configuration resource data and optical power performance data of the network management equipment in the optical transmission network OTN, and the theoretical optical power of each amplifier board is calculated. The two are compared to obtain the early warning information of the optical power of the amplifier board, which improves the accuracy, authenticity and update rate of the early warning data of the optical power of the amplifier board. Through automated technology and methods, the problems of slow manual import and update and poor data accuracy are effectively solved, and the efficiency of automatic early warning and monitoring is improved.

[0104] Based on the first embodiment of the automatic early warning method for the optical power of the amplifier board of the present invention, a second embodiment of the automatic early warning method for the optical power of the amplifier board of the present invention is proposed. Figure 6 , Figure 6 It is a flow chart of the second embodiment of the automatic early warning method for optical power of an amplifier board of the present invention.

[0105] In this embodiment, the method includes the following steps:

[0106] Step S201: Acquire configuration resource data and optical power performance data of a network management device in an optical transport network OTN.

[0107] Step S202: pre-process the configuration resource data according to the identifier of each amplifier board in the OTN to obtain the actual channel number, theoretical channel number, saturated output data and gain data of each amplifier board.

[0108] Step S203: According to the identifiers of the saturated output data and the gain data in the configuration resource data, optical power data with the same identifier is filtered out from the optical power performance data to obtain the actual optical power of each amplifier board.

[0109] Step S204: Obtain the theoretical optical power of each amplifier board according to the actual channel number, the theoretical channel number, the saturated output data and the gain data.

[0110] Step S205: Determine whether each amplifier board is a secondary amplifier board according to the configuration resource data.

[0111] Step S205 may include the following steps:

[0112] Step D10: Filter out first routing data corresponding to the service layer data from the subnet routing data.

[0113] Step D20: If both the source board and the sink board of each hop of data in the first routing data are amplifier boards, the source board is a primary amplifier board, and the sink board is a secondary amplifier board.

[0114] Specifically, query the OMS data and OTS data in the SNT data. Make a judgment based on whether the source board and the sink board of each hop of data stored in the OMS data and OTS data are amplifier boards. If both the source and sink boards are amplifier boards, it means that an amplifier board cascade has occurred. In this case, the source amplifier board is judged as a primary amplifier board, and the sink amplifier board is judged as a secondary amplifier board.

[0115] Step S206: If the amplifier board is a secondary amplifier board, compare the actual optical power of each amplifier board with the theoretical optical power to output amplifier board optical power warning information.

[0116] Step S207: If the amplifier board is a first-level amplifier board, no warning processing is performed.

[0117] It is easy to understand that if the amplifier board is a first-level amplifier board, since the optical power output of the first-level amplifier board cannot meet the standard, it is not necessary to compare the first-level amplifier board, but only compare the actual optical power and theoretical optical power of the second-level amplifier board, thereby reducing the workload of calculation. It is also helpful to achieve hierarchical warning and monitoring of the optical power of the amplifier board, and strengthen the refined management of the optical power warning of the amplifier board.

[0118] It is worth mentioning that step S205 can be performed before step 204, step 203 or even step S202, so as to further reduce the workload of calculation and improve the efficiency of early warning, which is not limited in this embodiment.
