Fig. 1 is a schematic flowchart of some embodiments of an IPTV group fault warning method according to the present disclosure.
In step 110, IPTV fault characteristic data corresponding to each fault scenario in a predetermined time period before the target prediction time range is obtained. The target prediction time range is, for example, a target prediction time or a target prediction time period.
The IPTV fault feature data may include IPTV fault feature data corresponding to an EPG (Electronic Program Guide) scene, IPTV fault feature data corresponding to a CDN (Content Delivery Network) scene, IPTV fault feature data corresponding to a set-top box scene, IPTV fault feature data corresponding to a product package scene, IPTV fault feature data corresponding to a Network layer device scene, IPTV fault feature data corresponding to an access failure scene, and IPTV fault feature data corresponding to a service authentication failure scene.
In step 120, IPTV fault characteristic data is input to the group fault prediction model corresponding to the fault scene, and the group fault amount in the target prediction time range is predicted. For example, the group barrier amount at a certain time or the group barrier amount in a certain time period in the future is predicted.
The group barrier prediction model comprises a group barrier prediction model under an EPG scene, a CDN scene, a set top box scene, a product package scene, a network layer equipment scene, an access failure scene and a service authentication failure scene.
In step 130, corresponding warning information is output according to the relationship between the real group barrier amount and the predicted group barrier amount in the target prediction time range.
In some embodiments, if the real group barrier amount is larger than or equal to the predicted group barrier amount of the first multiple, outputting first warning information; if the real group barrier amount is smaller than the predicted group barrier amount of the first multiple and larger than or equal to the predicted group barrier amount of the second multiple, outputting second warning information; if the real group barrier amount is less than the second multiple of the predicted group barrier amount and greater than or equal to the third multiple of the predicted group barrier amount, outputting third alarm information; wherein the first multiple is greater than the second multiple, the severity of the first warning information is greater than the severity of the second warning information, and the severity of the second warning information is greater than the severity of the third warning information.
For example, if the predicted group barrier amount at a target prediction time is P, the actual group barrier amount is C, and if C is equal to or greater than Ta × P, the serious alarm information is output, if C is smaller than Ta × P and equal to or greater than Tb × P, the important alarm information is output, and if C is smaller than Tb × P and equal to or greater than Tc, the general alarm information is output, where Ta > Tb > Tc.
In the embodiment, the group barrier prediction models in different scenes are used for predicting the group barrier amount of the target prediction time or the target prediction time period, and then the fault warning information can be sent out in time according to the relation between the real group barrier amount and the predicted group barrier amount, so that the requirements of real-time performance, accuracy, automation and comprehensiveness of IPTV operation and maintenance are met.
Fig. 2 is a flowchart illustrating another embodiment of an IPTV group fault warning method according to the disclosure.
In step 210, IPTV fault code data and IPTV platform user service data are obtained. The IPTV platform user service data comprises IPTV user home network element data and network topology.
In some embodiments, fault code data reported by the set-top box segment and fault code data reported by an IPTV user actively scanning a two-dimensional code of a television are collected. And then, acquiring network element data of the user such as EPG/CDN and network topology, wherein the network topology comprises a network transmission topology of the user from a set top box, an optical splitter and an OLT/BRAS/convergence switch, and the topology forms a network resource tree, wherein the same network equipment can serve a plurality of users. The IPTV subscriber home network element data and the network topology are for example stored in the same network element database.
In step 220, the IPTV fault code data and the IIPTV platform user service data are matched and aggregated, and sample fault feature data corresponding to each fault scenario in a plurality of fault scenarios is determined.
In some embodiments, the IPTV fault code data is stored to a Kafka message queue, e.g., the IPTV fault code data is posted to Kafka by way of an http request. And storing the IPTV user home network element data and the network topology into the HDFS. Reading and extracting a set top box code as an index, and writing network element data and network topology which an IPTV user belongs to into Redis for real-time query; IPTV fault code data in Kafka, user attribution network elements and network equipment resource trees in Redis are read through Spark and matched, generated fault common data are gathered to an EPG scene, a CDN scene, a set top box scene, a product package scene, a network layer equipment scene, an access failure scene and a service authentication failure scene, then characteristic data are extracted, and sample fault characteristic data corresponding to the EPG scene, sample fault characteristic data corresponding to the CDN scene, sample fault characteristic data corresponding to the set top box scene, sample fault characteristic data corresponding to the product package scene, sample fault characteristic data corresponding to the network layer equipment scene, sample fault characteristic data corresponding to the access failure scene and sample fault characteristic data corresponding to the service authentication failure scene are obtained.
In step 230, a group fault prediction model is trained based on the sample fault signature data. In some embodiments, codes are written by using a tensoflow frame to generate an algorithm model, and the group barrier prediction models under each scene are obtained by training the algorithm model, so as to predict the group barrier amount in the target prediction time range, for example, predict the group barrier amount at the target prediction time or predict the group barrier amount in the target prediction time period, according to the trained group barrier prediction models.
In some embodiments, the sample fault feature data may be sorted according to time, the sample fault feature data of a predetermined time period is used as an input parameter of the group barrier prediction model, the group barrier amount of the next time or the next time period of the predetermined time period is used as an output parameter of the group barrier prediction model, and a trained group barrier prediction model is obtained through training iteration.
In step 240, IPTV fault characteristic data corresponding to each fault scenario within a predetermined time period before the target prediction time is obtained. For example, the actual failure amount 12 times before the target prediction time, the actual failure amount yesterday at the same time, and the data attribute set are acquired.
In step 250, IPTV fault characteristic data is input to the group fault prediction model corresponding to the fault scene, and the group fault amount at the target prediction time is predicted.
In step 260, it is determined whether the real group fault amount at the target prediction time is greater than the predicted group fault amount by the first multiple, if so, step 270 is executed, otherwise, step 280 is executed.
In step 270, the critical alert information is sent and the alert contents are stored in a database.
In step 280, it is determined whether the real group barrier amount at the target prediction time is smaller than the first multiple of the predicted group barrier amount and greater than or equal to the second multiple of the predicted group barrier amount, if yes, step 290 is performed, otherwise, step 2100 is performed.
In step 290, important alarm information is sent out and the alarm content is saved in the database.
In step 2100, it is determined whether the real group barrier amount at the target prediction time is smaller than the second multiple of the predicted group barrier amount and greater than or equal to the third multiple of the predicted group barrier amount, if yes, step 2110 is performed, otherwise, step 2120 is performed.
At step 2110, general alarm information is issued and the alarm content is saved in a database.
At step 2120, no alarm is raised.
In the prior art, most of the group fault alarm thresholds are manually set by the maintainer through experience, and cannot be dynamically adjusted, however, the boundary and the grade of the group fault have strong correlation with whether the service is busy, the quality of the network layer and the evolution of the time sequence, and the manual setting cannot accurately delimit and grade the group fault. In the embodiment, when a large-scale fault occurs, fault warning information can be sent out in time by calculating and converging big data and utilizing the group fault prediction model, so that complaints of users can be effectively avoided, and the perception of the users is improved. In addition, due to the fact that the IPTV fault code data are matched with the IPTV platform user service data, the type of the user fault can be accurately obtained, and the specific fault point can be quickly located.
In some embodiments, if the output is the group barrier amount of the target prediction time period, the real group barrier amount of the target prediction time period is compared with the predicted group barrier amount, and the corresponding type of alarm information is output. The group barrier amount of the target prediction time period can constitute a time series curve. In addition, trend analysis can be performed on the real fault quantity and the predicted fault quantity, and meanwhile, support means such as a WebService interface and an Email log are provided for operation and maintenance analysis.
Fig. 3 is a flowchart illustrating an IPTV group fault warning method according to another embodiment of the disclosure.
In step 310, fault code data and IPTV user home network element data and network topology are collected. The fault code data includes a video source URL (Uniform Resource Locator) requested by the set top box and a requested EPG page.
In some embodiments, by analyzing the video source URL requested by the set-top box, the television channel corresponding to the failure can be determined; and analyzing the EPG page requested by the set top box, determining the EPG page and the EPG network element corresponding to the fault, and after positioning to a specific position, informing a broadcast and television live broadcast source to process or logging in the EPG to repair the page.
In step 320, the collected fault code data is cleaned, and data with irregular fault code reporting, missing user account and wrong field type are filtered out.
In step 330, the service account number and the STBID (set-top box production serial number identification) field of the cleaned fault code data are extracted.
In step 340, according to the service account and the STBID field of the IPTV fault code data, big data aggregation matching is performed on the IPTV fault code data and the IPTV user home network element data and network topology, so as to match the IPTV fault code data corresponding to the EPG device, the CDN node, the set top box model, the product package, the network layer device, and the service management platform, respectively.
In some embodiments, according to the service account number and the STBID field, the template of the user can be matched to be information such as baishitong or provincial channel, and the product package of the matched user is an intelligent version user or a high-definition or standard-definition user.
In some embodiments, according to the service account and the STBID field, network layer devices such as a PON (Passive Optical Network) port, an OLT (Optical Line Terminal)/BRAS (Broadband Remote Access Server) device code, and the like of an Access Network corresponding to the IPTV fault code data are matched. In this embodiment, when a fault occurs, the fault can be located to a specific PON port and OLT/BRAS equipment by querying the database.
In some embodiments, according to the service account and the STBID field, a set top box model, a software version, a capability platform where the IPTV fault code data is located, a bound EPG server, a group where the EPG server is located, a CDN node requested by a user, and the like corresponding to the IPTV fault code data are matched. In this embodiment, when a fault occurs, the fault can be located to a specific film source on the CDN node by querying the database.
And converging the matched intermediate results to EPG equipment, CDN nodes, set top box models, product packages, network layer equipment and service management platform scenes in real time, and storing converged convergence results into a database. When the user sees the error report, the system background can accurately acquire the type of the user fault and judge whether the user fault is a problem of network access or a fault of a service authentication module or the IPTV capability platform is in fault.
In the embodiment, the fault position corresponding to the fault code data can be located by querying the database, and compared with the method of locating the fault by querying a local log of the set top box by relying on a manufacturer, the fault locating efficiency is improved. In addition, in the embodiment, batch query and configuration can be realized through mass data analysis, convergence of common faults of users is realized, and the automation degree of the system is improved.
In step 350, missing data completion is performed on the IPTV fault code data corresponding to the matched EPG equipment, CDN node, set top box model, product package, network layer equipment, and service management platform according to the time sequence. For example, the time data missing in the time series is complemented.
In step 360, feature data of IPTV fault code data corresponding to the EPG device, the CDN node, the model of the set top box, the product package, and the network layer device are extracted, respectively, to obtain sample fault feature data corresponding to the EPG scene, sample fault feature data corresponding to the CDN scene, sample fault feature data corresponding to the set top box scene, sample fault feature data corresponding to the product package scene, and sample fault feature data corresponding to the network layer device scene; and determining sample fault characteristic data corresponding to an access failure scene and sample fault characteristic data corresponding to a service authentication failure scene according to the fault code meaning of IPTV fault code data corresponding to the service management platform.
In some embodiments, the sample fault signature data is initialized to N specific sets of discretized attributes.
In step 370, according to the sample fault feature data corresponding to each scenario, a group fault prediction model of the corresponding scenario is trained.
In some embodiments, for EPG scenarios, CDN scenarios, set-top box scenarios, product package scenarios, and network layer device scenarios, a neural network model with two BilTM (bidirectional LSTM) layers plus one Dense (fully connected layer) layer is used. For the access failure scene and the service authentication failure scene, a time series ARIMA model can be adopted because the fault amount is stable and the specific strong time periodicity is strong.
In some embodiments, sample fault characteristic data corresponding to an EPG scene is used as training data of a neural network model, and the neural network model is trained to obtain a group fault prediction model in the EPG scene.
For example, the failure data of the first 12 moments of the target prediction moment, the failure amount of the same moment of yesterday, the CDN node capability, and the CDN node type are used, and a total of 15 input values are used as one piece of training data. The CDN node type is divided into discrete attribute sets of 13 edge nodes +2 cross-domain nodes +1 province center node according to edge nodes, cross-domain nodes and province center nodes in a three-level framework of an IPTV platform and combining city and ground positions of node distribution.
In some embodiments, sample fault feature data corresponding to a CDN scene is used as training data of a neural network model, and the neural network model is trained to obtain a group fault prediction model in the CDN scene.
For example, the failure data of the first 12 times of the target predicted time, the failure amount of the same time yesterday, the EPG device type, the EPG packet, and a total of 15 input values are used as one piece of training data. The EPG equipment types are divided into ten EPG equipment types including a second-long-ZTE 1, a second-long-ZTE 2, a Changle-way KVM-ZTE1, a Changle-way KVM-ZTE2, a Changle-way-ZTE 1, a Changle-way-ZTE 2, a platform newly-expanded device, a Zhongxing-first platform EPG-KVM and a Zhongxing-second platform EPG-KVM according to the fact whether the EPG equipment types are cloud hosts, virtualization technology and the like, and the EPG groups are divided into 13 prefecture EPG groups and 1 default EPG groups according to the existing network IPTV platform.
In some embodiments, sample fault characteristic data corresponding to a set top box scene is used as training data of a neural network model, and the neural network model is trained to obtain a group barrier prediction model under the set top box scene.
For example, the data is divided according to the software versions of the set top box, if 82 software versions are adopted by 7 set top box manufacturers, due to the fact that the number of users of most software versions is small, reported fault records are few, and a part of old standard definition set top boxes do not have the capacity of reporting fault code data, training data are sparse; therefore, the data is smoothed, namely 0 is converted into an extremely small decimal number close to 0, and the situation that the gradient propagation of the neural network is inhibited by all 0 data is avoided. In addition, because the fault amount data of each set top box version does not show obvious periodicity, and the fault amount at the same moment of yesterday has little significance for model construction, the data format after preprocessing is as follows: the fault amount data of the first 12 moments of the target prediction moment and the version of the software of the set top box have 13 input values.
In some embodiments, sample fault feature data corresponding to a product package scene is used as training data of a neural network model, and the neural network model is trained to obtain a group barrier prediction model under the product package scene.
For example, 8 mainstream product packages including an iTV fashion a package, an iTV fashion package, an iTV hotel user, an iTV high-definition fashion a package (common edition), an iTV high-definition fashion a package (smart edition), an iTV high-definition fashion package (common edition), an iTV high-definition fashion package (smart edition), and an iTV high-definition hotel user are extracted. Therefore, the training set format in this scenario is: the failure amount data + the product package name of the first 12 moments of the target prediction moment are 13 input values.
In some embodiments, sample fault characteristic data corresponding to a network layer device scene is used as training data of a neural network model, and the neural network model is trained to obtain a group barrier prediction model under the network layer device scene;
in some embodiments, sample fault feature data corresponding to an access failure scene is used as training data of a time series prediction model, and the time series prediction model is trained to obtain a group fault prediction model in the access failure scene.
For example, firstly, the original time series is subjected to difference method to obtain stable time series, then AR, MA and ARMA models are respectively trained, and the parameter combination takes 3 as the maximum value, and 15 models are obtained in total. And after the training of the models is finished, calculating the AIC of each model to obtain ARIMA (p, d, q) with the minimum AIC, finally predicting a predicted value at the next moment in real time according to the models, and obtaining a predicted value of the fault amount after contrastive classification.
In some embodiments, sample fault feature data corresponding to a service authentication failure scene is used as training data of a time series prediction model, and the time series prediction model is trained to obtain a group barrier prediction model under the service authentication failure scene.
In the embodiment, sample fault feature data corresponding to an EPG scene, sample fault feature data corresponding to a CDN scene, sample fault feature data corresponding to a set-top box scene, sample fault feature data corresponding to a product package scene, sample fault feature data corresponding to a network layer device scene, sample fault feature data corresponding to an access failure scene, and sample fault feature data corresponding to a service authentication failure scene are extracted, and then an LSTM model and an ARIMA model are trained to obtain a group barrier prediction model in each scene, which facilitates subsequent prediction of a group barrier amount at a target time and a group barrier amount at a target time period, so that batch error reporting of a single set-top box model can be monitored and early warned, and batch access failure and service authentication failure of a certain user in a certain city can be detected and early warned. When a certain device or a certain type of set top box version has a large-scale fault, the fault reason can be positioned before a user complains in batches, an alarm is sent out in real time, automatic processing is achieved, and the requirements of real-time performance, accuracy, automation and comprehensiveness of IPTV operation and maintenance are met.
The method of the present disclosure will be described below by taking EPG group barrier prediction as an example.
When some EPG equipment has a fault, the background acquires massive set top box active reporting fault code data and fault code data reported by user code scanning, and writes the fault code data into two topics of itv _ error and itv _ user _ error of a Kafka message queue.
