Detailed Description

The technical solution of the present application is further elaborated below with reference to the drawings and the embodiments.

Fig. 1is a schematic flow chart of an implementation process of a method for determining a cause of a fault of an OTN device provided in an embodiment of the present application, and is applied to a monitoring platform, as shown in fig. 1, the method includes:

step 102: acquiring alarm information to be processed; the alarm information to be processed is alarm information of network equipment connected with the OTN equipment;

the OTN (optical transport network) refers to a transport network system that implements transport, multiplexing, routing, and monitoring of service signals in an optical domain, and ensures performance indexes and survivability thereof. The OTN device may be a device on an OTN system, and the OTN device may be an optical terminal device, an optical line device, an optical relay device, an optical add/drop multiplexer, and the like; the OTN system comprises OTN equipment and a network management server, wherein the OTN equipment is connected with the network equipment so as to realize the transmission of signals between different network equipment through the OTN equipment; the network devices may be computers, gateways, routers, bridges, and the like.

When the Network equipment is in fault, the monitoring unit of the Network equipment can give out an alarm signal according to the fault condition and send out alarm information to the monitoring platform through Simple Network Management Protocol (SNMP); the alarm information to be processed may be original alarm information of the network device, or alarm information obtained by screening the original alarm information.

The monitoring platform is also called a master alarm system, is a monitoring platform which is set up for monitoring the abnormality of all equipment in operation in a production network, can collect logs of all abnormal alarm related equipment, matches keywords to generate alarm information, and has an interface capability to receive the alarm information provided by other systems.

In the implementation process, the alarm information to be processed may be at least one piece of original alarm information sent by the network device and received by the monitoring platform, or may be the alarm information obtained by formatting the original alarm information. For example, at least one piece of original alarm information sent by the network device and received by the monitoring platform within a preset time period may be used as the alarm information to be processed; for another example, at least one piece of original alarm information in a preset time period may be formatted according to a timestamp generated by the original alarm information, and the formatted original alarm information may be used as the alarm information to be processed.

Step 104: extracting key equipment parameters from the alarm information to be processed, wherein the key equipment parameters are used for indicating the identification of the network equipment and the identification of a corresponding physical port;

the identifier of the network device may be an IP (Internet Protocol) address of the network device, a network device name of the network device, and the like, and the identifier of the physical port may be a physical port name of the physical port.

Step 106: determining a matching result between the key equipment parameter and the level information of the OTN equipment in a mapping table;

the mapping table may be understood as a resource table between the network device and the OTN device, and may pre-store the identifier of the network device, the identifier of the physical port, and the hierarchy information of the OTN device in advance during implementation, where the matching result includes matching and mismatching of the key device parameter and the hierarchy information of the OTN device. The hierarchy information of the OTN device represents the relationship among the layers of the OTN device, see the relationship among the layers in the OTS layer, the OCH layer and the OPU layer in the OTN device in table 1.

Assuming that the identifier of the network device extracted from the alarm information to be processed is a target network device name and the identifier of the extracted physical port is a target physical port name, the target network device name and the target physical port name may be considered to be matched with the hierarchical information of the OTN device under the condition that the network device name and the physical port name which are the same as the target network device name and the target physical port name are found from the mapping table.

And under the condition that the network equipment name and the physical port name which are the same as the target network equipment name and the target physical port name are not found from the mapping table, the target network equipment name and the target physical port name are considered to be not matched with the hierarchy information of the OTN equipment.

Step 108: and determining the fault reason of the OTN equipment based on the matching result.

And determining the OTN hierarchy which is possibly failed according to the matching result, and determining the failure reason of the OTN equipment according to the hierarchy information of the OTN hierarchy.

In some embodiments, the level information in the mapping table is the abnormal probability of the possible object, and the level information matched with the mapping table can be obtained from the matching result, referring to the embodiment of table 3, the number of the received alarm information is 8, and the number of the received alarm information matched with the mapping table is 6. And taking the target object with the maximum abnormal probability or the target object with the abnormal probability meeting the preset condition as the fault reason of the OTN equipment from the matched 6 pieces of layer-level information. Referring again to the embodiment of table 3, the probability of the second alarm message and the eighth alarm message is the largest, and the output may be: the 'maximum Fiber-AA-BB-01 anomaly probability of the OTS layer' and 'the second maximum 192.4THz anomaly probability of the OCH layer' are adopted, so that the fault reasons can be the Fiber-AA-BB-01 anomaly of the OTS layer and the 192.4THz anomaly of the OCH layer.

In other embodiments, the level information in the mapping table may have no abnormal probability of the object, and the level information matched with the mapping table may still be obtained from the matching result, and the matched target object may be obtained based on the matched level information, for example, the target object in the OTS information, the target object in the OCH information, and the target object in the OPU information; then, judging whether two target objects with physical connection relation are in a target level record table, for example, firstly, obtaining a target level record table between an OTS layer and an OCH layer according to the target objects in the OTS information; here, the target level record table records an object set of the OCH layer associated with a target object in the OTS information; in the target level record table, it is determined whether the target object in the OCH information is in the target level record table, i.e. whether the target object is in the object set of the OCH layer. If so, the target object in the OTS information is taken as the failure reason. If not, continuously acquiring a target level record table between the OCH layer and the OPU layer according to the target object in the OCH information; and in the target level record table, determining whether the target object in the OPU information is in the target level record table, if so, taking the target object in the OCH information as a fault reason, otherwise, taking the target object in the OPU information as the fault reason.

step S304: preprocessing formatting each piece of the at least one piece of original alarm information to obtain at least one piece of alarm information; the at least one piece of alarm information is alarm information of network equipment connected with the OTN equipment;

step S306: extracting key equipment parameters from the at least one piece of alarm information, wherein the key equipment parameters are used for indicating the identification of the network equipment and the identification of the corresponding physical port;

the matching result comprises matching and mismatching between the key equipment parameter and the hierarchy information of the OTN equipment, and abnormal probability of abnormality of an object in the hierarchy information of the OTN equipment under the matching condition;

step S310: determining the weight of each level of information in the OTN equipment;

wherein the OTN device may include an OPU (Optical Payload Unit) layer, an OCH (Optical Channel) layer, and an OTS (Optical Transmission Section) layer;

table 1is a mapping table provided in this embodiment, where the mapping table includes the network device name and the physical port name, and hierarchical information of an OPU layer, an OCH layer, and an OTS layer of the OTN device:

TABLE 1

The hierarchy information of the OPU layer is OPU information, and the OPU information comprises name information and port information of optical transmission equipment, the port rate of the OPU layer and the abnormal probability of an object in the OPU layer; the abnormal probability of the object in the OPU layer can be preset; the name information of the optical transmission device may be the client-side device in table 1, and may be "SZ-DW-AA", for example; the port information may be a client-side port in Table 1, and may be, for example, "C-1/3"; the port rate of the OPU layer may be the port rate in table 1, and may be, for example, "10 Gb/s"; the probability of abnormality of an object in the OPU layer may be the first probability in table 1, and may be "30%" for example.

The OCH information is information of the OCH layer related to the OPU layer, and comprises channel frequency of a channel, an initial station and a termination station, channel speed and abnormal probability of an object in the OCH layer; the abnormal probability of the object in the OCH layer can be preset; the channel frequency may be "192.1 THz"; the origination site may be "AA"; the termination site may be "BB"; the channel rate may be "10 Gb/s"; the anomaly probability of the object in the OCH layer may be the second probability in table 1, and may be "40%" for example.

The hierarchy information of the OTS layer is OTS information, and the OTS information comprises operator optical fiber information, total bandwidth information of the service currently borne by the OTS layer and the abnormal probability of an object in the OTS layer; the abnormal probability of the object in the OTS layer can be preset; the operator Fiber information may be "Fiber-AA-BB-01", the total bandwidth information of the traffic now carried by the OTS layer may be the carried rate in table 1, and the anomaly probability of the object in the OTS layer may be a third probability in table 1, for example, "30%".

The OPU layer is an information structure for adapting the transmission of customer information over an optical channel; the optical path payload unit is used to combine the client information, overhead needed to adapt the client signal rate and OPUK payload rate, and other OPUK overhead to support client signaling. These overheads are specific adaptation overheads, the capacity of the OPUK is divided by k, k being 0, 1, 2e, 3, 4.

The OCH layer is the core of the whole OTN and is the main functional carrier of the OTN; the OCH layer is mainly responsible for routing and wavelength allocation of customer signals of various formats and provides networking functions for end-to-end optical channels for transparent transmission of subscriber signals of various formats.

The OTS layer is responsible for handling optical transmission segment overhead to ensure integrity of optical transmission segment adaptation information while enabling detection and control of optical amplifiers or repeaters.

The weight can be preset or obtained by calculation; each OTN device includes hierarchical information of three layers, i.e., OPU, OCH, and OTS, and weights of the hierarchical information of different OTN devices in the same OTN hierarchy may be the same or different.

Step S312: and determining the fault reason of the OTN equipment based on the weight of each level of information in the OTN equipment and the abnormal probability of the object in each level of information in the OTN equipment.

Each layer level information of the OTN device may include at least one object, and each object corresponds to an abnormal probability that an abnormality may occur; an initial value of an abnormal probability of an object in the hierarchy information of each OTN device, that is, an initial abnormal probability, may be determined according to a first ratio between a channel rate of an OCH channel in the OTN device and an OPU port rate, and when the first ratio is equal to 1, the initial abnormal probability of the OCH layer may be required to be the maximum, for example, may be 40%; the initial anomaly probability of the OPU layer is small, for example, may be 30%; the initial anomaly probability of the OTS layer is minimal, and may be 30%, for example; when the first ratio is greater than 1, it may be required that the initial anomaly probability of the OPU layer is the largest, for example, may be 80% or 60%, the initial anomaly probability of the OCH layer is smaller, for example, may be 15% or 30%, and the initial anomaly probability of the OTS layer is the smallest, for example, may be 5% or 10%. The size relation among the initial abnormal probabilities of the OTS layer, the OCH layer and the OPU layer is determined by judging whether the first ratio is larger than 1, so that the determination of the initial abnormal probabilities of the OTN layers is more flexible and accurate.

Further, there may be a logarithmic function relationship between an initial value y of the anomaly probability of the object in the OPU layer and a first ratio x between a channel rate of the OCH in the OTN device and a port rate of the OPU, where y is a dependent variable and x is an independent variable.

In some embodiments, the logarithmic function may be a natural logarithmic function. For example, for a certain network, the expression of y and x can be expressed by formula (1):

y＝0.20ln(x)+0.31 (1)；

the above 0.20 and 0.31 are preferred values obtained by multiple tests in this embodiment, and in other embodiments, other values may be set according to actual needs, and are not limited specifically. Referring to fig. 2, in the case that the first ratio is 10, the initial abnormal probability of the OPU layer is about 77%, the initial abnormal probability of the OCH layer may be 20%, and the initial abnormal probability of the OTS layer may be 7%; in a case that the first ratio is 1, an initial abnormal probability of the OPU layer is about 31%, the initial abnormal probability of the OCH layer may be 40%, and the initial abnormal probability of the OTS layer may be 30%. The initial value of the abnormal probability of the object in the OPU layer is determined according to the logarithmic function relationship, and then the initial values of the abnormal probabilities of the OCH layer and the OTS layer are determined according to the initial value of the abnormal probability of the OPU layer, so that the accuracy of determining the abnormal probability can be further improved.

In the embodiment of the application, the fault reason of the OTN equipment is determined according to the weight of each level of information in the OTN equipment and the abnormal probability of the object in each level of information in the OTN equipment, so that the fault reason can be determined more accurately; in addition, the initial value of the abnormal probability of the object abnormal in each layer level information of the OTN equipment is determined according to the first ratio between the OCH channel rate and the OPU port rate, so that the determination of the initial value of the abnormal probability can be more accurate.

Wherein the preset conditions may be that the final probability in the ranking results is the largest and the second largest; then "Fiber-AA-BB-01" of the OTS layer with a final probability of 1.12 and "192.4 THz" of the OCH layer with a final probability of 0.72 can be determined as target objects; it can be determined that the cause of the failure of the OTN device can be an operator major optical interruption, i.e. an optical interruption with an operator Fiber number "Fiber-AA-BB-01".

In the embodiment of the application, the target object is screened out according to the final probability sorting result of the object, and the fault reason of the OTN equipment is determined according to the target object and the hierarchy information of the layer where the target object is located, so that the fault reason of the OTN equipment can be determined more accurately.

step S702: acquiring at least one piece of original alarm information from at least one piece of network equipment;

step S704: preprocessing formatting each piece of the at least one piece of original alarm information to obtain at least one piece of alarm information; the at least one piece of alarm information is alarm information of network equipment connected with the OTN equipment;

step S706: extracting key equipment parameters from the at least one piece of alarm information, wherein the key equipment parameters are used for indicating the identification of the network equipment and the identification of the corresponding physical port;

step S708: determining a matching result between the key equipment parameter and the level information of the OTN equipment in a mapping table;

step S710: determining the matching quantity between the key equipment parameter of each alarm information and the level information of the OTN equipment in the mapping table based on the matching result of each alarm information;

step S712: determining a first ratio between the OCH rate and the OPU rate in the OTN device;

step S714: determining a second ratio between the number of matches and the first ratio;

step S716: and determining the weight of each layer level information in the OTN equipment based on the second ratio.

Step S718: for an object in each level information, determining the final probability of the object by accumulation based on the number of times of matching the object, the weight of the level information where the object is located and the abnormal probability of the object;

step S720: sequencing the final probabilities of all the objects to obtain a sequencing result;

step S722: screening out target objects meeting preset conditions based on the sorting result;

step S724: determining a fault reason of the OTN equipment based on the target object and the hierarchy information of the layer where the target object is located;

step S726: outputting the fault reason to prompt a network manager of the OTN equipment;

step S728: obtaining a feedback result of the network management of the OTN equipment to the fault reason;

step S730: and maintaining or updating the abnormal probability of the object in each level of information in the mapping table based on the feedback result.

The master alarm system may output the failure cause to prompt a network manager of the OTN device, and the network manager may check an actual failure scene to obtain a feedback result of the failure cause, that is, may obtain an actual failure, and if the OTN level where the actual failure is located matches the OTN level where the object having the maximum value of the final probability is located, maintain the abnormal probability of the object in the information of each level in the mapping table; if the OTN level where the actual fault is located is matched with the OTN level where the object with the second largest value of the final probability is located, the probability of the OTN layer where the object with the second largest value is located may be increased by 10%, and the probabilities of the other OTN layers may be decreased by 10%; if the OTN level where the actual failure is located is not matched with the OTN level where the object with the maximum value of the final probability is located or the OTN level where the object with the second maximum value is located, the probability of the actual correct OTN layer may be increased by 20%, and the probabilities of the other OTN layers may be decreased by 20%.

In the embodiment of the application, the abnormal probability of the object in each level of information in the mapping table is dynamically maintained or updated according to the actual fault, so that the fault reason of the OTN equipment can be more accurately determined.

In the related art, there are two main methods related to an alarm convergence method of an optical transport network OTN device (which may also be referred to as a method for determining a failure cause of the OTN device):

a first alarm convergence method is shown in fig. 3, in which a total alarm system collects alarm information of an OTN device and alarm information of a network device in an OTN system, and performs uniform convergence on the collected alarm information of the OTN device and the collected alarm information of the network device; when the OTN equipment fails, pushing the alarm information of the OTN equipment to an OTN network management system of a manufacturer to which the OTN equipment belongs through a private protocol of the manufacturer to which the OTN equipment belongs; then, the OTN network management systems of each manufacturer push the alarm information of the corresponding OTN device to the master alarm system through a Telemetry (telemeasurement) technology or a Common Object Request Broker Architecture (CORBA); meanwhile, the alarm information of the Network device is pushed to the total alarm system through a Simple Network Management Protocol (SNMP).

The total alarm system converges the alarm information of the network equipment according to the connection relation between the network equipment and the OTN equipment by comparing the alarm information of the OTN equipment and the alarm information of the network equipment which occur in a specific time period; and finally, converging the alarm information of the OTN equipment according to the hierarchical relation of the OPU, the OCH and the OTS. And finally, converging to obtain the root fault reason of the OTN equipment, and finishing the whole alarm convergence process.

Telemetry is a remote data acquisition technology for monitoring the performance and faults of equipment, and the Telemetry technology adopts a push mode to acquire abundant monitoring data in time, so that the network fault can be quickly positioned, and the problem of network operation and maintenance is solved. Push mode is a technique based on a client/server mechanism where the server actively sends information to the client.

CORBA is a standard Object-oriented application program system specification (OMG) made by the Object Management Group (Object Management Group), which is a Distributed processing Environment (Distributed Computing Environment) solution for Object Management organization_，DCE), a solution proposed by the interconnection of hardware and software systems; the role of the OMG organization is to provide a common framework for application development, to develop industrial guidelines and pairsThe development of object technology is accelerated according to management specifications.

A second alarm convergence method is shown in fig. 4, and first converges the alarm information of the OTN device through an OTN network management system of a vendor to which the OTN device belongs, and then pushes the converged alarm information of the OTN device to a master alarm system; when the OTN equipment fails, specific alarm information of the OTN equipment is pushed to an OTN network management system of the affiliated manufacturer through a private protocol of the affiliated manufacturer, and the OTN network management system converges according to the hierarchical relationship of OPU, OCH and OTS through a preset alarm convergence rule; and pushing the alarm information of the converged OTN equipment to a master alarm system through telemeasurement or CORBA corresponding to OTN network management systems of different manufacturers, and simultaneously pushing the alarm information of the network equipment to the master alarm system through SNMP.

The total alarm system converges the alarm information of the network equipment by comparing the alarm information of the converged OTN equipment and the alarm information of the network equipment in a specific time period according to the pre-entered corresponding relationship between the network equipment and the OTN equipment, and finally completes the whole alarm convergence process.

However, in the two alarm convergence methods, the alarm information on the OTN system is accessed to the total alarm system, and a certain development cost is required. Because the OTN system is relatively closed, the interfaces for reporting data by the OTN network management system of the OTN system are usually privatized and customized. The access of the master alarm system has high corresponding development cost and long development period, and the proprietary protocol may need to adapt to new rules after the development is completed and the later version of the network management is updated.

In addition, when the OTN system fails, a large amount of alarm information of the OTN device and alarm information of the network device may appear at the same time. The alarm formats of all OTN manufacturers are inconsistent with the alarm formats of network equipment manufacturers, and the methods for alarm convergence in the OTN equipment scene are also inconsistent, so that if the methods are directly used for analysis, the complexity of calculation is relatively high, and further, the time for analyzing and processing the fault is relatively long.

Moreover, if a large number of alarms of the network device and alarms of the OTN device are simultaneously sent in a short time, the total alarm system may occasionally lose alarms, and once the alarm information of the OTN system or the alarm information of the network device is lost, the calculation convergence may be affected, and even according to the previously established algorithm, the convergence failure may occur.

According to the embodiment of the application, the complexity of alarm convergence under the situation related to optical transmission can be reduced by analyzing the characteristics of the optical transport network and using a probability iterative learning mode, and the time of alarm convergence is shortened.

The method and the device for processing the alarm information of the network equipment can preprocess the alarm information of the network equipment by using a formatting method, and match the abnormal probability of the object in the hierarchical information of the OTN equipment corresponding to the pre-recorded network equipment based on the corresponding relation between the network equipment and the OTN equipment pre-recorded in the mapping table.

According to the embodiment of the application, the alarm convergence result can be calculated by using a probability iteration and weight assignment method, the convergence result can be confirmed again, and the corresponding probability is trained to increase the accuracy of subsequent convergence calculation.

Referring to fig. 5, in a scenario where an OTN system is abnormal and affects a network device, the method may select only the alarm information of the network device for formatting preprocessing in response to a situation that different OTN device manufacturers and network device manufacturers have many types of alarm information, a large number of alarm information, and possibly alarm loss, and converge the alarm information caused by the abnormality of the OTN system by using a specific probability method; after alarm convergence is completed, iterative optimization is performed according to the actual fault reason, and the probability value under the scene corresponding to the next fault is updated. With the method, as the number of times of convergence increases, the corresponding convergence judgment can be trained more accurately.

According to the alarm convergence method provided by the embodiment of the application, the alarm information on the OTN system is not acquired or directly shielded, and the alarm information of the OTN system in the whole amount is not directly calculated at the beginning of the process; the method comprises the steps of carrying out formatting pretreatment on network equipment alarms collected by a main alarm system, and then calculating the probability to quickly converge the alarms of the network equipment and give a convergence conclusion; after convergence is completed, the difference between the actual fault and the probability convergence result can be compared, and the corresponding probability condition is updated to be used as a new basis for next convergence.

Referring to fig. 6 and 7, an embodiment of the present application may provide an alarm convergence method:

step 602: acquiring a network equipment alarm;

the main alarm system acquires alarm information of the network equipment through SNMP;

wherein, the alarm information of the down type of the physical port can be regarded as the alarm information which is valuable for deducing the fault reason of the OTN equipment; in the embodiment of the application, the alarm information of the OTN system is not involved, and only the alarm information of the network device is analyzed, so that the alarm information of all the OTN systems can be converged first (that is, the alarm information of all the OTN systems does not participate in the subsequent calculation), and only the alarm information of the network device is left.

Step 604: screening alarm physical down types;

the master alarm system screens alarm information of a physical port down type;

the total alarm system can perform preliminary screening on the alarm information of the network equipment, and can perform screening through keywords such as DOWN, DOWN and the like in a network alarm log, and only leave the alarm information of the type of the DOWN physical port in the alarm information of the network equipment; if the type of network equipment alarm is not satisfied, the next processing is not carried out.

Step 606: formatting an alarm extraction device and a port;

the master alarm system carries out formatting treatment on the alarm information of the down type of the physical port so as to extract the name of the network equipment and the name of the physical port;

wherein, the network device name and the physical port name can be extracted from the alarm information of the physical port down type; because the formats of the alarm SNMP logs of various manufacturers are different, but the alarm information of the down type of the physical port comprises the name of the network equipment to be alarmed and the specific physical port information of the down type, the name of the network equipment and the name of the physical port can be extracted by combining a regular expression and a keyword, and the name of the network equipment can be customized by a user, so the user can extract the name of the network equipment through the regular expression according to the rule; although names of different manufacturers are different, the physical ports in the network alarm information may be matched by requiring that keywords such as "Ethernet", "Gigabit Ethernet", "Fast Ethernet", and the like are included, and keywords such as "port-channel", "vlan (virtual local area network)" are not included.

In the embodiment of the present application, the following 3 specific pieces of alarm information of the network device may be taken as an example for description:

the first piece of alarm information may be: oct 2920: 12: 5010.126.231.782020 SZ-NET-B%% 10IFNET/5/LINK _ UPDOWN: Line protocol state on the interface force-gigabit Ethernet2/0/1changed to down.

The second warning message may be: SZ-NET-D:2020Oct 2912: 17:53.90 CST% ETHPORT-5-IF _ DOWN _ LINK _ FAILURE: Interface Ethernet1/17is DOWN (Link FAILURE) Timestamp: 2020-10-2912: 17:53.

The third piece of alarm information may be: SZ-NET-D:2020Oct 2912: 17:59.902 CST:% ETH _ PORT _ CHANNEL-5-PORT _ UP: PORT-CHANNEL1301: Ethernet1/18is UP.

Because the network equipment name is self-defined by a user, the network equipment name can be obtained through a specific regular expression as 'SZ-NET-B', and a corresponding physical port can be matched as 'Forty-Gigabit Ethernet 2/0/1' according to a keyword, so that the first piece of alarm information meets the requirement. Similarly, the name of the network device "SZ-NET-D" and the name of the physical port "Ethernet 1/17" can be extracted from the second alarm message; the third warning message contains the "Ethernet", but also contains the "port-channel", and does not contain the keywords such as "DOWN", etc., which does not meet the requirement, and the third warning message can be discarded.

Step 608: matching the pre-input information to obtain the latest probability;

step 610: whether probability information can be matched; if yes, go to step 612; if not, go to step 614;

step 612: placing the alarm into a cache pool;

step 614: discard the alert;

the master alarm system matches the network equipment name and the physical port name with the pre-entered hierarchy information of the OTN equipment, and obtains the latest probability that the object of the hierarchy information of the OTN equipment corresponding to the network equipment name and the physical port name is abnormal;

if the network device name and the physical port name can be matched with the hierarchy information of a specific OTN device, acquiring the OTN device information of three layers of OPU, OCH and OTS of the hierarchy information and probability information corresponding to the hierarchy, and putting the alarm information corresponding to the network device name and the physical port name into a cache pool; and if the network equipment name and the physical port name are not matched with the hierarchy information of any OTN equipment, discarding the alarm information corresponding to the network equipment name and the physical port name, and carrying a keyword of 'not relating to an OTN system' in the alarm information.

Step 616: whether a new increase exists within 15 seconds; if yes, go to step 608; if not, go to step 618;

step 618: counting the number of alarms;

the total alarm system judges whether new alarm information of the network equipment which can be matched with the hierarchy information of the OTN equipment is generated within a specific time length;

if no new alarm information of the network device capable of matching the hierarchy information of the OTN device is generated within the time length, counting the number of the alarm information of all the matched network devices acquired within the time length, and ending the alarm formatting process.

The format of the hierarchy information of the pre-entered OTN device is shown in table 1.

Referring to table 1, each network device name and physical port name may form a key index of hierarchy information of the pre-entered OTN device, and according to the key index, an OPU layer of the OTN carrying transmission of the network device may be associated, where the OPU layer includes optical transmission device name information and specific port information, a port rate of the OPU layer, and a probability of possible abnormality, where the optical transmission device name information may be the client-side device in table 1, and the port information may be the client-side port in table 1; then, associating information of the OCH layer corresponding to the OPU, including the channel frequency of the channel, the starting station and the ending station, the channel speed corresponding to the channel, and the probability of possible abnormality; and finally, the operator optical fiber information associated to the OTS layer corresponding to the OCH includes the optical fiber number of the operator, the total bandwidth information of the service currently carried by the OTS, namely, the carried rate, and the probability of corresponding possible abnormality.

In an embodiment, the total alarm system may determine an initial abnormal probability of the hierarchy information of each OTN device according to a ratio of an OCH channel rate to an OPU port rate in the hierarchy information of each OTN device;

the hierarchy information of the OTN equipment is pre-recorded in the master alarm system according to the actually used OTN system of the network equipment, and is used for inquiring the hierarchy information of the corresponding OTN equipment according to the name of the network equipment and the name of the physical port. The abnormal probability corresponding to the hierarchy of each OTN device has an initialized value, namely the initial abnormal probability of the hierarchy information of the OTN device; this value needs to be determined with reference to the ratio of the OCH channel rate and the OPU port rate, where the ratio is 1: 1, the initial abnormal probability of the OCH layer may be required to be the maximum, for example, may be 40%; the initial anomaly probability of the OPU layer is small, for example, may be 30%; the initial anomaly probability of the OTS layer is minimal, and may be 30%, for example; when the ratio is greater than 1: 1, the initial abnormal probability of the OPU layer may be required to be the largest, for example, may be 80% or 60%, the initial abnormal probability of the OCH layer is smaller, for example, may be 15% or 30%, and the initial abnormal probability of the OTS layer is the smallest, for example, may be 5% or 10%, in which case, the initial abnormal probability of the OPU layer and the ratio of the "channel rate of OCH" to the "port rate of OPU" are changed in a "logarithmic curve"; assuming that the ratio is x and the initial anomaly probability of the OPU layer is y, the initial anomaly probability of the OPU layer may be determined according to formula (1):

y＝0.20ln(x)+0.31 (1)；

referring to fig. 2, in the case that the ratio is 10, the initial anomaly probability of the OPU layer may be 80%; in the case where the ratio is 20, the initial anomaly probability of the OPU layer may be 90%.

Through the alarm formatting from the above step 602 to step 618, the specific alarm information of the network device carried by the OTN system may be obtained, and the level information and the number of the OTN devices on the OTN system associated with the alarm information and the probability that the level information of the OTN device corresponding to the alarm information of each network device is abnormal are determined.

After determining the initial abnormal probability of the hierarchy information of each OTN device, referring to fig. 7, the alarm convergence method further includes calculating a probability convergence alarm in the following steps 620 to 632:

step 620: counting the number of alarms;

step 622: matching alarm coefficients of all layers;

the total alarm system obtains the number, and the total alarm system can determine the weight of each layer level information in each OTN device according to the number and the maximum value of the ratio;

the number may also be understood as the number of alarm information of the network device that matches the hierarchical information of the OTN device, and the total alarm system may correspondingly search the weight of each layer of each corresponding OTN device in the number according to the number of alarm information that meets the requirement and has an abnormal probability counted in a specific time.

In one embodiment, the weights of different rules may be selected according to the maximum value of the ratio of the OCH channel rate to the OPU port rate in the OTN system; in the same OTN system, if there are different ratios, such as 4: 1 and 10: 1, then the maximum 10: 1is "the ratio of the channel rate of OCH to the port rate of OPU", that is, 10 is used as the reference for judging the weight.

It should be understood that OPU, OCH, and OTS are three hierarchical relationships, wherein the OPU layer is at the bottom layer of the three hierarchical levels, and the number of corresponding hierarchical information is the largest; the OCH layer is arranged in the middle layer of the three levels, and the number of corresponding level information is in the middle; the OTS layer is located at an upper layer of the three levels, and the corresponding level information is fewer in number. Therefore, when the weight is judged, the weight can be confirmed by comparing the total alarm quantity of the network equipment which is matched with the level information of the OTN equipment according to the requirement with the ratio of the OCH channel rate and the OPU port rate, so that the judgment accuracy is improved. Specifically, referring to table 2, in the case that the number is equal to or less than the ratio, the weights of the OPU layer, the OCH layer, and the OTS layer may be determined to be 1.2, 0.8, and 0.4, respectively; in the case that the number is greater than the ratio and is less than or equal to twice the ratio, the weights of the OPU layer, the OCH layer, and the OTS layer may be determined to be 0.4, 1.2, and 0.8, respectively; in the case where the number is more than twice the ratio, the weights of the OPU layer, the OCH layer, and the OTS layer may be determined to be 0.4, 0.8, and 1.2, respectively.

Step 624: calculating probability and alarm convergence;

step 626: outputting a fault reason;

the total alarm system calculates the probability of the OTN system and determines the fault reason of the OTN equipment according to the probability; the master alarm system can output the fault reason to prompt the network management of the OTN equipment to remove the core and check the actual fault.

Weighting and calculating the collected alarm information of all the network devices by using the abnormal probability of the object in the level information of each OTN device and the weights of the OPU layer, the OCH layer and the OTS layer where the object is located; the final probability of the object is determined by accumulation. The final probabilities of the objects can be sequenced to obtain a sequencing result, specific object information in the hierarchy information of the target layer and the target layer of the OTN equipment corresponding to the two maximum final probabilities can be output, and the fault reason of the OTN equipment is determined according to the hierarchy and the object information; and finally, deleting the alarm information of the network equipment to finish the whole alarm convergence.

Step 628: checking whether the result meets the actual condition; if yes, go to step 632; if not, go to step 630.

Wherein the checking result can be considered as an actual fault.

Step 630: updating the abnormal probability of each matched layer;

step 632: the flow ends.

The main alarm system compares the actual fault with the predicted fault reason; and adjusting the abnormal probability of the object in the level information of each OTN device according to the comparison result.

In one embodiment, after the whole alarm convergence is completed, the actual fault scene can be checked by means of an OTN network management system of the OTN system; if the OTN hierarchy where the actual fault is located is matched with the hierarchy of the OTN equipment corresponding to the object with the maximum final probability in the corresponding hierarchy information, the abnormal probability of the object with the abnormality in the hierarchy information of each OTN equipment is kept unchanged, and the process is ended; if the OTN hierarchy where the actual fault is located matches the hierarchy of the OTN device corresponding to the object having the second highest final probability, the probability of the object having the abnormality in the hierarchy information of the target layer of the OTN device corresponding to the second highest final probability may be increased by 10%, and the probability of the object having the abnormality in the hierarchy information of other layers may be decreased by 10% in total, for example, the probability of the object having the abnormality in the hierarchy information of each layer in other layers may be decreased by 5% respectively. If the OTN hierarchy where the actual fault is located and the hierarchies of the OTN devices corresponding to the objects in the corresponding hierarchy information and the objects with the first and second highest final probabilities are not matched, the abnormal probability of the object occurring abnormality in the hierarchy information of the layer which should be correct actually may be increased by 20%, and the probabilities of the other layers may be decreased by 20%, for example, the abnormal probability of the object occurring abnormality in the hierarchy information of each layer in the other hierarchies may be decreased by 10%, respectively, the actual correct hierarchy is the hierarchy of the OTN device corresponding to the object with the smallest final probability, and the process ends.

The method using probability iteration in the embodiment of the application is mainly used for solving the problem that when a large amount of alarm information of network equipment in a network environment and alarm information of OTN equipment are concurrent, part of alarm information is lost, so that the method is more suitable for the network alarm environment in the field through training by using the probability iteration method.

The embodiment of the present application further provides a method for determining a cause of a fault of an OTN device, where the method includes:

step S802: under the condition of a certain OTN system failure, the total alarm system receives the pushing of the alarm information of the network equipment;

wherein, the alarm information of the network device may be the following 8 pieces of alarm information:

the first piece of alarm information: SZ-NET-A:2020Oct 2920: 12:48 CST:% ETHPORT-5-IF _ DOWN _ INITIALIZING: Interface Ethernet1/1is DOWN (Initializing).

And the second alarm message: SZ-NET-A:2020Oct 2920: 12:49 CST:% ETHPORT-5-IF _ DOWN _ INITIALIZING: Interface Ethernet1/2is DOWN (Link failure).

The third piece of alarm information: SZ-NET-A:2020Oct 2920: 12:49 CST:% ETHPORT-5-IF _ DOWN _ INITIALIZING: Interface Port-channel 1is DOWN (Link failure).

The fourth warning message: SZ-NET-A:2020Oct 2920: 12:49 CST:% ETHPORT-5-IF _ DOWN _ INITIALIZING: Interface Ethernet1/3is DOWN (Link failure).

And fifth alarm information: oct 2920: 12: 5010.126.231.782020 SZ-NET-B%% 10IFNET/5/LINK _ UPDOWN: Line protocol state on the interface force-Gigabit Ethernet2/0/1changed to down.

The sixth piece of alarm information: oct 2920: 12: 5010.126.231.782020 SZ-NET-B%% 10IFNET/5/LINK _ UPDOWN: Line protocol state on the interface force-Gigabit Ethernet2/0/2changed to down.

The seventh piece of alarm information: SZ-NET-C:2020Oct 2920: 12:51 CST% ETHPORT-5-IF _ DOWN _ INITIALIZING: Interface Ethernet3/1is DOWN (Initializing).

The eighth alarm message: SZ-NET-C:2020Oct 2920: 12:59 CST:% ETHPORT-5-IF _ DOWN _ INITIALIZING: Interface Ethernet6/2is DOWN (Initializing).

Step S804: performing formatting pretreatment on the alarm information of the network equipment to obtain a network equipment name and a physical port name corresponding to the alarm information;

the alarm information of the network equipment can be screened, and the third alarm information is not a specific physical port and is screened out; the eighth alarm information is screened because the corresponding probability cannot be found in the total alarm system; the combination of the network device name and the keyword of the physical port name in a single piece of alarm information can be extracted through a regular expression and the keyword, and the data formatted in the following table 4, that is, the network device name and the physical port name corresponding to the alarm information, is obtained:

TABLE 4

Step S806: in the total alarm system, determining the hierarchy information of the OTN equipment matched with the network equipment name and the physical port name, and determining the abnormal probability of the object in the hierarchy information of the OTN equipment;

the table 3is a mapping table, where the mapping table includes the network device name, the physical port name, and the hierarchy information of the OTN device; for convenience of presentation, table 3 hides part of information in the mapping table, and highlights the abnormal probability of the object in the hierarchical information.

TABLE 3

Step S808: the total alarm system determines the weight of each layer level information in each OTN device according to the number of the layer level information in the OTN device matched with the network device name and the physical port name and the ratio of the OCH channel rate to the OPU port rate;

calculating the number of hierarchical information in the OTN equipment matched with the network equipment name and the physical port name to be 6, wherein in the OTN system with the same OTS, the maximum ratio of the OCH channel rate to the OPU port rate is 4; if the number of alarm messages of the network device meeting the requirement is 6, then since 6 is between one-time ratio 4 and two-time ratio 8, the weight combination selected according to the requirement may be that the weight of the OPU layer is 0.4, the weight of the OCH layer is 1.2, and the weight of the OTS layer is 0.8.

Step S810, the total alarm system calculates the probability of the OTN system;

wherein, the abnormal probability of the abnormality of the 'Fiber-AA-BB-01' of the OTS layer can be as follows: 30% by 0.8+ 10% by 0.8+ 30% by 0.8-1.12.

The abnormal probability of "192.1 THz", "192.2 THz", "192.3 THz", "192.5 THz" of the OCH layer being abnormal may be: 40%. 1.2 ═ 0.48; the anomaly probability of "192.4 THz" being anomalous may be: 30%. 1.2+ 30%. 1.2 ═ 0.72

Since the objects in the hierarchy information of the OPU layer only appear once, there is no accumulation, and thus the maximum value may be: 60%. 0.4 ═ 0.24.

Step S812: the total alarm system determines the fault reason of the OTN equipment according to the probability;

wherein, because the probability of the second alarm information and the eighth alarm information is the maximum, the first, the third, the fourth, the fifth and the seventh alarm information can be deleted, and the output 'the Fiber-AA-BB-01 abnormal probability of the OTS layer is the maximum', and the output 'the 192.4THz abnormal probability of the OCH layer is the second maximum'.

Step S814: the main alarm system compares the actual fault with the determined fault reason of the OTN equipment, and adjusts the abnormal probability of the object in the level information of each OTN equipment according to the comparison result;

the total alarm system can check the actual fault condition of the OTN system by means of the OTN network management system of the OTN system, and confirms that the main light interruption of an operator is confirmed, namely the optical Fiber interruption with the operator optical Fiber number of 'Fiber-AA-BB-01', so that the alarm convergence is accurate and consistent with the actual condition, and the probability of correspondingly updating an object in the level information of the OTN equipment in a mapping table of the network equipment is not needed; and if the actual fault is inconsistent with the fault reason, correspondingly updating the probability of the object in the hierarchy information of the OTN equipment in the mapping table of the network equipment.

The embodiment of the present application further provides a method for determining a cause of a failure of an OTN device, where the method includes:

step S902: acquiring at least one piece of original alarm information from at least one piece of network equipment;

step S904: preprocessing formatting each piece of the at least one piece of original alarm information to obtain at least one piece of alarm information; the at least one piece of alarm information is alarm information of network equipment connected with the OTN equipment;

If the contents in the first number and each piece of hierarchical information completely conform to the contents in the second number and each piece of hierarchical information, the target object of the OTS information is considered to be matched with the object of the OCH layer in the first hierarchical record table; if the first number is not equal to the second number, or although the first number is equal to the second number, the content in each piece of hierarchical information is not completely consistent, the target object of the OTS information is not adapted to the object of the OCH layer in the first hierarchical record table; it should be noted that, because the content in table 5 is a subset of the content in table 6, the same level information of the OCH layer can be always found in table 6 for any level information of the OCH layer in table 5, and further, it can be determined whether the first number and the second number are equal to determine that the target object of the OTS information is adapted to the object of the OCH layer in the first level record table.
