Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The application scenario of the application is as follows: with the development of internet technology, multicast technology is widely used. In the multicast system, each network hierarchy is associated from high to low once according to the priority, the network hierarchy with the highest priority only sends one piece of data, the destination address of the data is each network unit in the network hierarchy with the lowest priority, and each network unit in the network hierarchy with the lowest priority can obtain the copy of the data sent by the network hierarchy with the highest priority. Therefore, the network hierarchy with higher priority may be affected by the failure of the network hierarchy with lower priority, and therefore, it is very important to accurately locate the failed network hierarchy in the multicast system.
In the related art, fault monitoring is independently performed at each network level, and when a certain network level fails, an alarm is given.
However, when a plurality of network levels fail simultaneously, the way of independently monitoring the failure at each network level cannot perform correlation analysis on each network level, and cannot quickly locate the failure source, which results in delay of failure processing time and failure processing timeliness.
The present application provides a fault diagnosis method, apparatus, device and storage medium, which aim to solve the above technical problems.
Fig. 1 is a fault diagnosis method provided in an embodiment of the present application, and as shown in fig. 1, the method includes:
step 101, obtaining a failure time period of a first network layer, wherein the first network layer fails at least one time point in the failure time period.
In this embodiment, specifically, an execution main body of this embodiment is a terminal device, a server or a controller that is disposed on the terminal device, or other apparatuses or devices that can execute this embodiment, and this embodiment is described by taking the execution main body as an application controller that is disposed on the terminal device as an example.
The method of this embodiment may be applied to a multicast system including a plurality of network levels, different network levels corresponding to different priorities, and a first network level corresponding to a lowest priority. Exemplarily, fig. 1a is a schematic structural diagram of an IPTV service system provided in this embodiment, and as shown in fig. 1a, the multicast system may be an IPTV service system, in which the IPTV service system includes a plurality of network hierarchies with different priorities, and the network hierarchies are from high to low according to the priorities, and the IPTV service system includes: a broadcast control platform, a transcoding platform, RP (rendezvous point for multicast), CR (core router), SR (service router), OLT (optical line terminal) and a user set-top box side.
The failure time period of the first network layer refers to a time period when the first network layer fails, and the duration of the failure time period has no special requirement, and may be several minutes, several hours or one day, for example. The method for obtaining the failure time period of the first network layer may be conventional in the art, for example, the failure time period may be obtained according to the user failure feedback of the first network layer, or the failure time period of the first network layer failing may be obtained through system monitoring and detection.
Exemplarily, for the IPTV service system shown in fig. 1a, the set-top box side of the user corresponds to the first network layer level in this embodiment; when a user watches live broadcast through an IPTV service system, the user finds that the live broadcast fails, so that the live broadcast cannot be carried out or the quality of the live broadcast is poor, and can feed back the failure condition to a controller; after the controller obtains the fault feedback of the user, according to the fault feedback, the time when the fault occurs, which is fed back by the user, may be used as a fault time period, or according to the MAC address of the set top box or the IPTV service account corresponding to the user, the time period when the fault occurs at the set top box side corresponding to the user may be queried, and is used as the fault time period in this embodiment.
And step 102, determining a fault time point of the first network layer according to the fault time period.
In this embodiment, specifically, according to the failure time period, a time point when the first network hierarchy fails within the failure time period is determined, and the time point is taken as a failure time point. Wherein, the first network layer may fail at one time point in the failure time period, or may fail at a plurality of time points in the failure time period; when the first network layer only has a fault at one time point in the fault time period, directly taking the time point as the fault time point of the embodiment; when the first network hierarchy fails at a plurality of points in time within the failure time period, the point in time at which the corresponding failure condition is most serious may be taken as the failure point in time of the present embodiment.
Step 103, according to the failure time point, obtaining the data stream type received by the first network level at the failure time point, and determining the data stream type received by the first network level at the failure time point as a failure data stream.
The anchor system is characterized in that the network level with the highest priority only sends one data stream at a time, and after the data stream is transmitted to the network level with the lowest priority, the data stream is copied and transmitted to the network level with the lowest priority according to the requirement of the network level with the lowest priority.
In this embodiment, specifically, in the multicast system of this embodiment, the data stream sent by the network level with the highest priority is composed of multiple types of data streams, the data stream sent by the network level with the highest priority is transmitted to the first network level through the remaining network levels with different priorities, and then one type of data stream is copied and sent to the first network level according to the requirement of the first network level. Exemplarily, in the IPTV service system shown in fig. 1a, a broadcast control platform (program source) transmits a video stream to other service levels, where the video stream includes a plurality of video channels, for example, the video stream transmitted by the broadcast control platform (program source) to other service levels includes video channel 1, video channel 2, and video channel 3 simultaneously; video streams sent by a broadcast control platform (program source) are sequentially transmitted to a set top box side of a user through an RP, a CR, an SR and an OLT, then the OLT copies a certain video stream in the video streams sent by the broadcast control platform (program source) and sends the copied video stream to the set top box side of the user according to the requirement of the set top box side of the user, for example, the OLT copies the data stream of a video channel 1 and sends the copied data stream to the set top box side of the user, and the set top box of the user receives the data stream of the video channel 1 and plays the video channel 1 through a player; when the video channel 1 played by the player fails, the video channel 1 is taken as a failed video stream.
And step 104, determining a fault network layer with a fault according to the fault time point and the fault data stream.
In the present embodiment, specifically, for the failure time point and the failure data stream determined in the foregoing steps, in the multicast system, it is queried in all network hierarchies whether the failure data has failed at the failure time point, and the network hierarchy in which the failure has occurred is determined as the failed network hierarchy. When there are a plurality of network hierarchies with faults, the network hierarchy with the highest priority in the network hierarchy with faults can be determined as the network hierarchy with faults.
In this embodiment, a failure time period of a first network layer is obtained, where the first network layer fails at least at one time point in the failure time period; determining a fault time point of the first network layer according to the fault time period; acquiring the type of the data stream received by the first network layer at the fault time point according to the fault time point, and determining the type of the data stream received by the first network layer at the fault time point as a fault data stream; and determining the fault network level with the fault according to the fault time point and the fault data stream. The method of the embodiment searches the network hierarchy with the fault from the multicast system aiming at the fault time point when the first network hierarchy has the fault and the fault data stream type with the fault, can quickly locate the fault network hierarchy, improves the fault processing efficiency, and improves the service use experience of users.
Fig. 2 is a schematic flow chart of another fault diagnosis method provided in an embodiment of the present application, and based on fig. 1, as shown in fig. 2, the method includes:
step 201, obtaining a failure time period of a first network layer, wherein the first network layer fails at least one time point in the failure time period.
In the present embodiment, specifically, the method and principle of step 201 are similar to or the same as those of step 101, see the related description of step 101.
On the basis of step 101, the first network layer in this embodiment includes several network elements, and different network elements correspond to different users. Exemplarily, fig. 2a is a schematic diagram of an IPTV service system provided in this embodiment, as shown in fig. 2a, a set-top box side of a user corresponds to a first network unit in this embodiment, the set-top box side of the user includes a plurality of set-top boxes of users, such as a set-top box 1, a set-top box 2, and a set-top box 3, and each set-top box of the user corresponds to one user, such as a user 1, a user 2, and a user 3.
Optionally, in this embodiment, the obtaining of the failure time of the first network layer may be: acquiring fault feedback sent by a user through a network unit corresponding to the user, wherein the fault feedback comprises a time period when the network unit corresponding to the user fails; and according to the fault feedback, taking the time period when the network unit corresponding to the user is in fault as the fault time period of the first network layer. In this method, since the failure feedback sent by the user includes the time period during which the network element fails, in order to reduce the troubleshooting time, the time period during which the network element fails included in the failure feedback is directly used as the failure time period in this embodiment. Illustratively, when the user 1 in fig. 2a watches a program by using the set top box 1 on 12/2018 at 9:00-10:00, the user 1 may send a failure feedback through the set top box 1 or by other means, and the failure feedback includes a time period "9: 00-10:00 on 12/2018, the time period is determined as a failure time period.
Alternatively, in this embodiment, the obtaining of the failure time of the first network layer may be: acquiring fault feedback sent by a user through a network unit corresponding to the user, wherein the fault feedback comprises a user identifier of the user and/or a network unit identifier of the network unit corresponding to the user; and acquiring the time period when the network unit corresponding to the user fails according to the user identifier and/or the network unit identifier, and taking the time period when the network unit corresponding to the user fails as the failure time period of the first network level. In the method, since the failure feedback sent by the user does not include the time period in which the network element fails, the time period in which the network element corresponding to the user fails needs to be queried and acquired according to the user identifier and/or the network element identifier, and then the acquired time period in which the network element fails is used as the failure time period in this embodiment. Illustratively, when the user 1 in fig. 2a watches a program by using the set top box 1, it is found that the program is watched to be faulty, the user 1 sends a fault feedback through the set top box 1 or other means, where the user feedback only includes a user identifier (e.g., an IPTV account) of the user 1 and/or a set top box identifier (e.g., a set top box MAC address) of the set top box 1, and according to the user identifier (e.g., the IPTV account) of the user 1 and/or the set top box identifier (e.g., the set top box MAC address) of the set top box 1, it is queried that the user 1 watches the program and has a fault on the above 9:00-10:00 days 12/2018, so that a time period "9: 00-10: 00" on 12.
Step 202, determining a fault time point of a first network layer fault according to a fault time period; and according to the failure time point, acquiring the data stream type received by the first network layer at the failure time point, and determining the data stream type received by the first network layer at the failure time point as a failure data stream.
In this embodiment, specifically, in addition to the contents described in step 101 and step 102, the method further includes: the data stream transmission indexes corresponding to the network levels are periodically obtained according to preset time intervals, wherein a first preset time interval corresponding to a first network level is larger than second preset time intervals corresponding to other network levels, and a first period corresponding to the first network level is larger than second periods corresponding to other network levels. Different network levels can correspond to different data stream transmission indexes, wherein the data stream transmission indexes are used for representing the capability of the corresponding network level for transmitting data streams, the higher the value of the data stream transmission index is, the stronger the capability of the corresponding network level for transmitting the data streams is, and on the contrary, the lower the value of the data stream transmission index is, the worse the capability of the corresponding network level for transmitting the data streams is. Multicast systems may fail when the network level has a poor ability to transport data streams. A first preset time interval corresponding to a first network level and a second preset time interval corresponding to other network levels can be selected in a larger range, for example, the first preset time interval can be 15min, and the second preset time interval can be 1 s; the first preset time interval is greater than the second preset time interval, the first period is greater than the second period, the number of the collected data stream transmission indexes of the network levels with other priorities can be greater than the number of the data stream transmission indexes of the first network level, the data stream transmission indexes of each first network level are ensured to have one corresponding data stream transmission index of the network level with other priorities, and the accuracy of the data backtracking in the later period is ensured.
The method for obtaining the data stream transmission indicator corresponding to each network level may be a conventional method in the art, and for example, the data stream transmission indicator corresponding to each network level may be obtained by using an active stream pulling probe and/or a passive image analysis probe.
Determining a failure time point of the first network layer failure according to the failure time period, comprising: according to the fault time period, acquiring a first data stream transmission index corresponding to each sampling point of the first network layer in the fault time period, wherein the sampling point is a time point for acquiring the first data stream transmission index; and determining the sampling points corresponding to the first data stream transmission indexes lower than the first preset value as fault time points according to the first data stream transmission indexes corresponding to the sampling points of the first network level. The value of the first preset value is determined according to actual needs, if the multicast system has a high demand on the data stream transmission capability of each network level, a higher first preset value should be set, and conversely, if the multicast system has a low demand on the data stream transmission capability of each network level, a lower first preset value may also be set.
In the method, if there are at least two first data stream transmission indexes corresponding to the sampling points in the fault time period that are lower than a first preset value, and values of the first data stream transmission indexes corresponding to the sampling points are not equal to each other, determining the sampling point corresponding to the first data stream transmission index that is lower than the first preset value as a fault time point, including: and determining a sampling point corresponding to the first data stream transmission index with the lowest value in the first data stream transmission indexes lower than the first preset value as a fault time point.

In this embodiment, there is no particular limitation on the data type of the data stream transmission indicator corresponding to each network layer, and all the relevant data capable of reflecting the data stream transmission capability of each network layer can be used as the data stream transmission indicator in this embodiment.

In this embodiment, specifically, if the data stream transmission index corresponding to a certain network level is smaller than the second preset value, it may be considered that the data stream transmission capability of the network level is deteriorated due to a failure of the network level; in the multicast system, the data stream is transmitted from the network level with the high priority to the network level with the low priority, that is, after the network level with the high priority fails, the network level with the low priority will inevitably fail, and therefore, the network level with the highest priority in the network levels corresponding to the data stream transmission index smaller than the second preset value is determined as the failed network level in this embodiment. The value of the second preset value may be determined according to actual needs, if the multicast system has a high demand on the data stream transmission capability of each network level, a higher second preset value should be set, otherwise, if the multicast system has a low demand on the data stream transmission capability of each network level, a lower second preset value may also be set, and the second preset value may be the same as or different from the first preset value.

The number of the N values is the same as the number of the network levels in this embodiment, and if the failed network level cannot be determined after the N times of execution, the first network level is determined as the failed network level.
