Background

The traditional operation and maintenance tool generally operates in a network device oriented manner, and such traditional operation and maintenance method or tool generally configures each network device individually, and can obtain a very good effect when processing devices with simple models such as an access layer switch, or in a scene with a single configuration.

However, with the rapid development of internet application technology, communication technology, and data processing technology, the demand for network access has increased explosively.

The opening of one access relationship may involve configuration modifications of multiple devices, while hundreds or thousands of access relationships may be opened for a data center each day. Because a single network device lacks perception of global topology information, under the task of opening access relationships, the operation and maintenance tool facing the device cannot meet the increasingly complex requirements of automation operation and maintenance of the east-west direction (namely, flow among devices in a data center).

In summary, the conventional network operation and maintenance method has the following disadvantages: the requirement of automation operation and maintenance under multiple devices and complex scenes is difficult to meet.

Fig. 2 shows a flow diagram of a method 200 for network operation and maintenance according to an embodiment of the disclosure. Fig. 8 shows a schematic diagram of a network configuration concurrency principle. The method 200 is described below in conjunction with fig. 2 and 8. The method 200 may be performed by the computing device 110 as shown in FIG. 1, or may be performed at the electronic device 1000 shown in FIG. 10. It should be understood that method 200 may also include additional steps not shown and/or may omit steps shown, as the scope of the disclosure is not limited in this respect.

In step 202, if the computing device 110 retrieves the operation and maintenance requirement instruction, the full-network topology information and the access relationship information are obtained, where the access relationship information includes access relationship information about at least one access relationship, and the access relationship information at least indicates a start point and an end point in an access path corresponding to the access relationship.

The operation and maintenance requirement instruction at least comprises a timing task instruction which is preset according to the operation and maintenance requirement, an operation and maintenance requirement instruction which is imported by operation and maintenance personnel, and an operation and maintenance requirement instruction which is input by the operation and maintenance personnel in real time; these operation and maintenance requirement instructions can be preset and adjusted according to the information and state of the network and the actual configuration requirements.

Before acquiring the topology information and the access relationship information of the whole network, the computing device 110 may call a configuration file to initialize a topology information data source of the whole network, so as to convert the topology information data of the whole network into a specific structured format, so as to store, read, call, process, etc. the topology information data; meanwhile, the access relation information providing device 130 may also call the configuration file to initialize the access relation information data source, and convert the access relation information data into a specific structured format, so as to facilitate storage, reading, calling, processing, and the like of the access relation information data.

The access relation information may be, for example, access relation information of at least one access relation stored in a form of a data table, and each piece of access relation information may include corresponding access path information (such as nodes in an access path, node device information, and the like), association information with other access relations, and the like; it should be noted that the access relationship information of an access relationship at least needs to include an indication of a start point and an end point in an access path corresponding to the access relationship, so that the computing device 110 may obtain the access path corresponding to the access relationship and information of all nodes in the corresponding access path according to the node information of the access path corresponding to the access relationship.

Regarding the starting point and the end point in the access path, the starting point and the end point are only two nodes that one access path needs to include at least, each node corresponds to one device, and the configuration tasks executed by the network configuration are also directed at the devices of the nodes; in a data center scenario, an access path will typically contain at least 3 nodes, a start point, an end point, and a firewall node.

Regarding the topology information of the whole network, it is necessary to define in advance, for example, each device in the whole network, the relationship between the devices, each transmission medium, and the like. The topology information of the whole network at least comprises topology structure of the whole network, equipment information of all equipment, connection relation between equipment, transmission media, data transmission line information, configuration task screening conditions, execution condition information and the like.

In step 204, the computing device 110 generates topology information of each access relationship based on the access relationship information, where the topology information of one access relationship at least indicates an access path corresponding to the access relationship and device information of all devices in the access path.

The topology information about an access relationship may further include: all transmission media, connection line information, node position information, configuration task screening conditions and execution condition information of each device in the access path corresponding to the access relationship.

The device information may include at least a device model, location information, interface information, and connection information and association relationship with other devices of the current device.

For example, referring to fig. 8, the obtained access relationship information a includes three access relationships, that is, an access relationship a1, an access relationship a2, and an access relationship a3, and generates a topological relationship p1 of the access relationship a1, a topological relationship p2 of the access relationship a2, and a topological relationship p3 of the access relationship a3, respectively; the scheme realizes concurrency based on the access relation so as to realize concurrency configuration based on the access relation on the network equipment.

In step 206, the computing device 110 obtains a configuration task corresponding to each access relationship based on the topology information of each access relationship.

The configuration tasks may be entered in advance according to the conditions and requirements of the devices, the configuration task corresponding to one access relationship at least includes an operation that is required to be executed by each device on the access path corresponding to the access relationship, the executed operations may be customized, and the configuration task that triggers the device to operate may be sent to the devices only by knowing the address information of the corresponding device. The operations to be executed at least include executing some filtering conditions, such as filtering the shortest path among multiple devices, whether the path contains a certain device, determining whether two devices are connected, returning path information connecting two devices, and the like.

At step 208, the computing device 110 performs configuration tasks corresponding to each of the access relationships in parallel.

With respect to obtaining a configuration task corresponding to an access relation, executing a configuration task corresponding to an access relation in parallel, for example, referring to fig. 8, generating a configuration task T corresponding to access relations a1, a2 and a3 based on topological relations p1, p2 and p3 respectively _a1 Configure task T _a2 Configure task T _a3 And executing the configuration tasks T corresponding to the access relations a1-a3 in parallel _a1 、T _a2 And T _a3 (ii) a According to the scheme, the devices on the access path corresponding to each access relation are configured in parallel by taking the access relation as an object for each device related to the operation and maintenance requirements, rather than being configured by taking a single device as a unit, so that the relevance among the devices is greatly improved, the compatibility of the configuration is better, and the configuration efficiency is higher.

At step 210, the computing device 110 obtains execution results of all configuration tasks to aggregate the execution results for indicating the configuration status of the network.

Regarding the execution result, the execution result of the configuration task corresponding to one access relationship includes the configuration state of the device of each node on the access path corresponding to the one access relationship, such as successful configuration, failed configuration, current configuration state, and the like.

In the above scheme, for the access relationship information, the topology information of each access relationship can be generated only by the starting point and the ending point in the access path corresponding to each access relationship, and the information of all the node devices on the access path corresponding to each access relationship is acquired, so that network configuration is performed by taking the access relationship as an object, and the network configuration efficiency is effectively improved. In addition, the execution results of all the configuration tasks can be acquired, so that the execution results are aggregated to realize the indication of the configuration state of the network; can provide good guidance for operation and maintenance personnel. Therefore, the method 200 for network operation and maintenance provided by the embodiment of the present disclosure can improve the network configuration efficiency, thereby meeting the automatic operation and maintenance requirements under the complex scene with multiple devices.

FIG. 3 shows a flow diagram of a method 300 for parallel execution of a sub-configuration task according to an embodiment of the present disclosure. The method will be described below with reference to fig. 3 and 8. The method 300 may be performed by the computing device 110 as shown in FIG. 1, or may be performed at the electronic device 1000 shown in FIG. 10. It should be understood that method 300 may also include additional steps not shown and/or may omit steps shown, as the scope of the disclosure is not limited in this respect.

In step 302, the computing device 110 obtains a sub-configuration task corresponding to each device in the access path corresponding to each access relationship based on the configuration task corresponding to each access relationship.

Referring to fig. 8, for example, the obtained access relationship information a includes three access relationships, namely, an access relationship a1, an access relationship a2, and an access relationship a3, and the configuration task T is generated according to topology information p1-p3 of the three access relationships _a1 Configuration task T _a2 Configuration task T _a3 (ii) a Wherein, the node devices in the access path corresponding to the access relationship a1 have Z0, Z1, Z2 and Z3, and the sub-configuration tasks of the devices Z0-Z3 with respect to the access relationship a1 are respectively generated according to the access relationship a1, for example, the sub-configuration task T is generated _a1-Z0 、T _a1-Z1 、T _a1-Z2 And T _a1-Z3 (ii) a Node devices in an access path corresponding to the access relationship a2 are provided with Z1, Z3 and Z5, and a sub-configuration task of the devices Z1, Z3 and Z5 about the access relationship a2 is respectively generated according to the access relationship a 2; node devices in an access path corresponding to the access relationship a3 are Z0, Z3, Z4, Z5 and Z6, and a sub-configuration task of the devices Z0, Z3, Z4, Z5 and Z6 about the access relationship a3 is respectively generated according to the access relationship a3; it should be noted that the same device may be involved in multiple access relationships, i.e. different accessesThe paths may include the same device, for example, the access paths a1, a2, and a3 all include the node device Z3; thus, there may be multiple sub-configuration tasks for the same device.

At step 304, the computing device 110 performs all sub-configuration tasks of any of the at least one access relationships in parallel.

Referring to fig. 8, for example, in the access relationship information a, the configuration tasks T corresponding to the access relationship a1, the access relationship a2 and the access relationship a3 are executed in parallel _a1 Configure task T _a2 Configuring task T _a3 (ii) a The configuration tasks respectively have a plurality of sub-configuration tasks; for example, all the sub-configuration tasks in the access relationships a1, a2 and a3, i.e. all the sub-configuration tasks of the devices Z0, Z1, Z2, Z3, Z4, Z5 and Z6 are executed in parallel; the method realizes the concurrent generation of the sub-configuration tasks and the concurrent execution of the sub-configuration tasks.

At step 306, the computing device 110 determines whether the same device needs to perform multiple sub-configuration tasks.

For example, referring to fig. 8, the device Z3 relates to three access relationships a1, a2 and a3 at the same time, so that the device Z3 is a node on three access paths corresponding to the access relationships a1, a2 and a3 at the same time, and 3 sub-configuration tasks are generated with respect to the device Z3. When each node device only has one sub-configuration task, all the sub-configuration tasks can be executed in parallel in the actual execution process; however, when the same node device has multiple sub-configuration tasks, during the actual configuration process, the same device may not be able to execute the multiple configuration tasks at the same time, and at this time, it needs to determine whether the same device needs to execute the multiple sub-configuration tasks, and the execution sequence of the multiple sub-configuration tasks of the same device during the actual execution process of the configuration tasks.

At step 308, if the computing device 110 determines that the same device needs to perform multiple sub-configuration tasks, the multiple sub-configuration tasks of the same device are performed according to the predetermined execution order rule.

At step 310, if the computing device 110 determines that the same device does not need to perform multiple sub-configuration tasks, the sub-configuration tasks are performed in parallel.

The predetermined sequence rule may be, for example, that the sub-configuration tasks are executed first according to the time when the same device actually receives the sub-configuration tasks; the priority of execution may also be a1 > a2 > a3 according to the association order among the access relations, for example, the access relations a1, a2 and a3 are in relation to the execution order rule of the same node device task; the sequence rule of processing a plurality of sub-configuration tasks by the same node can be determined in advance according to the operation and maintenance task requirement in an actual scene.

In some embodiments, the computing device 110 may also invoke a task template corresponding to the devices in the access path based on the pre-entered task library and the device information of the devices, so as to generate a sub-configuration task corresponding to each device in the access path; and

the sub-configuration tasks at least comprise an information acquisition task, a configuration backup task and a configuration issuing task.

Regarding the task template, a plurality of nodes may be involved in the access path, and information such as model and manufacturer of each node device may be different, which results in different formats of configuration task files compatible with different node devices; regarding the pre-entered task library, the task library at least comprises information such as a task template, a node type and/or a task parameter corresponding to the node device, and automatic differential configuration of multiple devices can be realized, so that configuration efficiency is improved.

According to the scheme, the concurrence of operation and maintenance required tasks is realized, and the access relation information of each access relation is parallelly acquired according to the access relation information; then based on the topology information of the whole network, taking the access relations as objects, and generating the topology relations of the access relations in parallel according to the access relation information of each access relation; generating configuration tasks corresponding to the access relations in parallel based on the topological relations of the access relations; then, based on the access path node information, all node devices on the access path corresponding to the access relationship are taken as objects, and the sub-configuration tasks of all the node devices in each access relationship are generated in parallel; finally, executing the sub-configuration tasks of any access relation in the at least one access relation in parallel; according to the method for network operation and maintenance, in each link for generating the configuration task based on the access relation information, the access relation and the node equipment in the path corresponding to the access relation are respectively used as objects for carrying out concurrence for many times, so that the efficiency of network configuration is greatly improved, and the relevance among the equipment needing to be configured can be considered, so that the high-efficiency and high-quality network configuration is realized when the network operation and maintenance requirements are met.

Fig. 4 shows a flowchart of a method 400 for configuring task execution result indication according to an embodiment of the present disclosure, fig. 9 shows a schematic diagram of network configuration status indication according to an embodiment of the present disclosure, and the method 400 is explained below with reference to fig. 4, fig. 8, and fig. 9. The method 400 may be performed by the computing device 110 as shown in FIG. 1, or may be performed at the electronic device 1000 shown in FIG. 10. It should be understood that method 400 may also include additional steps not shown and/or may omit steps shown, as the scope of the disclosure is not limited in this respect.

At step 402, the computing device 110 obtains the results of the execution of each of the sub-configuration tasks.

For example, referring to fig. 8 and 9, the execution results of all the sub-configuration tasks of the access relationships a1, a2, and a3 are obtained.

At step 404, the computing device 110 associates each of the sub-configuration task execution results with an access relationship based on the execution results of each of the sub-configuration tasks.

In step 406, the computing device 110 aggregates the execution results of all the sub-configuration tasks executed by the same device based on the association between the execution result of each sub-configuration task and the access relationship, so as to indicate the configuration status of the network based on the aggregated execution results.

For example, referring to fig. 9, in fig. 9, taking the configuration task execution results corresponding to the access relationships a1, a2, and a3 illustrated in fig. 8 as an example, taking the node device as a set, associating the configuration task execution results with the access relationships, showing the execution results of each sub-configuration task, and implementing an indication of the network configuration state; for example, the device Z0, the configuration is successful with respect to the access relation a1, and the configuration is failed with respect to the access relation a 2; it should be noted that fig. 9 only illustrates the execution results of the sub-configuration tasks of the partial node devices corresponding to the access relationships a1, a2, and a3, and only indicates one association manner between the execution results and the access relationships, and in the actual use process, the result association and the configuration state indication may also be performed in other manners, and the execution results of the sub-configuration tasks may also be aggregated in other aggregation manners.

The scheme can associate the execution condition of the configuration task with the equipment for configuration and multiple access relations, and clearly indicate the configuration result of each equipment in each access relation, so that operation and maintenance personnel can know the execution condition of the configuration task, the configuration conditions of each equipment and each access path.

The method 500 may be performed by the computing device 110 as shown in FIG. 1, or may be performed at the electronic device 1000 shown in FIG. 10. It should be understood that method 500 may also include additional steps not shown and/or may omit steps shown, as the scope of the present disclosure is not limited in this respect.

In step 502, the computing device 110 obtains an error code fed back by a device corresponding to the sub-configuration task whose execution result is failure.

At step 504, the computing device 110 associates and aggregates the error codes fed back by the device with the corresponding sub-configuration tasks to the execution results.

Regarding the error code, for example, the error code of the sub-configuration task "access relationship a3 — configuration failure" of the device Z0 with respect to the access relationship 3 in fig. 9 is "xxxZ0a3xxx", and the error code is used to indicate the reason why the configuration of the device Z0 fails.

At step 506, the computing device 110 determines whether an error code of the device is detected. If the computing device 110 does not detect a device error code, proceed to step 502.

At step 508, if the computing device 110 detects an error code for a device, the sub-configuration task is re-executed for the device to which the error code corresponds according to predetermined error handling rules.

Regarding the predetermined error processing rules, various error code processing rules may be pre-entered according to error reasons corresponding to respective error codes, so that the computing device 110 automatically debugs the node device in which an error occurs in response to the error code, or automatically generates a new sub-configuration task according to error code debugging configuration parameters, so as to implement re-execution of the sub-configuration task on the node device with failed configuration.

By the scheme, the error reason of the node equipment with the failure of the sub-configuration task can be acquired, the failed sub-configuration task can be conveniently re-executed after timely debugging, and the configuration efficiency is improved.

FIG. 6 illustrates a flow diagram of a method 600 for determining access relationship topology information in accordance with an embodiment of the disclosure. The method 600 may be performed by the computing device 110 as shown in FIG. 1, or may be performed at the electronic device 1000 shown in FIG. 10. It should be understood that method 600 may also include additional steps not shown and/or may omit steps shown, as the scope of the disclosure is not limited in this respect.

In step 602, the computing device 110 determines an access path corresponding to each access relationship based on the nodes included in each piece of access relationship information.

Regarding the nodes included in each piece of access relationship information, at least the number of the node or the number of the node device is included, so as to obtain the device information of the node device; for example, the access relationship information of the access relationship a1 includes nodes Z0 and Z3, and the access relationship information of the access relationship a3 includes nodes Z0, Z5, and Z6. It should be noted that, usually, at least the start point and the end point of the access path corresponding to the access relationship need to be included to determine one access path, but more nodes may also be included.

At step 604, the computing device 110 determines all devices involved in each access relationship based on the access path corresponding to each access relationship.

After the access path is determined, all nodes of the access path can be obtained, so that after one access path is determined, all devices related to the access relationship corresponding to the access path can be determined; for example, determining the access path "Z0 → Z1 → Z2 → Z3" makes it possible to determine that all the devices involved in the access relationship a1 are four devices "Z0, Z1, Z2 and Z3".

In step 606, the computing device 110 obtains device information of all devices involved in each access relationship, where the device information at least includes a device model, location information, interface information, and connection information with other devices of the current device.

The connection information with other devices at least comprises the connection relation between the devices, the specific connection mode, the connected interface information and the transmission medium information; it should be noted that the connection information with other devices is not limited to devices connected to the entire network, and may be devices connected to an external network.

Regarding the transmission line, when the devices at the edge of the intranet topology need to connect to external devices, an external transmission medium, such as an external line, is usually used; therefore, the scheme provides an extra private line message so as to distinguish an external line from other internal devices and lines when the whole network topology initialization is carried out; therefore, when the configuration task fails and the error reason is the external private line, it is obvious that the internal network operation and maintenance cannot solve the problems, and only an alarm can be given, so that the operation and maintenance personnel can remind the operator of the external network private line to solve the related problems.

For example, the storage of the private line information may be performed in the form of a data table, which may include information such as a private line number, a private line operator, a vlan number, a private line type, a private line bandwidth, a home terminal name, a home terminal private line port address, an opposite terminal name, and an opposite terminal private line port address; the special line number, the special line operator, the vlan number, the special line type and the special line bandwidth are necessary options, titles beginning at a local end and an opposite end are initialized to be a center and a branch class at one end of the special line, the name at one end of the special line and the port address of the special line are necessary items, and information such as a special line interface can be expanded according to actual conditions; the external lines can be screened and judged through the configuration task, such as according to the key field, the line number, whether a conflicting vlan number exists or not, a conflicting IP and the like.

According to the scheme, the complete access path corresponding to each access relation can be determined according to the path nodes included in each piece of access relation information, the equipment information of all node equipment is obtained, and independent management and processing of external circuits are provided, so that operation and maintenance personnel can confirm the reason of configuration failure in time, problems caused by non-internal reasons are eliminated in time, and operation and maintenance efficiency is improved.

Fig. 7 shows a flow diagram of a method 700 for determining an access path according to an embodiment of the present disclosure. The method 700 may be performed by the computing device 110 as shown in FIG. 1, or may be performed at the electronic device 1000 shown in FIG. 10. It should be understood that method 700 may also include additional steps not shown and/or may omit steps shown, as the scope of the present disclosure is not limited in this respect.

At step 702, the computing device 110 is operable to determine the number of access paths that exist based on the nodes in an access relationship.

In step 704, if the computing device 110 determines that only one access path exists based on the nodes in one access relationship, the only one access path is determined as the access path corresponding to the one access relationship.

In step 706, if the computing device 110 determines that at least two access paths exist based on the node in one access relationship, according to a predetermined path determination rule, one access path is determined from the determined at least two access paths as the access path corresponding to the one access relationship.

As for the predetermined path determination rule, a rule about how to determine an access path when at least two access paths exist in one access relationship may be entered in advance according to requirements, for example, a priority rule of a node may be set, and a path with a high node priority in the selected paths is determined as the access path; the priority of the node can be determined or adjusted according to factors such as a network state, an equipment hardware state, a node association relation, an access relation type and the like, and can also be dynamically adjusted according to the execution success rate of the sub-configuration task; the node priority rules may be set in the topology information.

At step 708, if based on a node in an access relationship, the computing device 110 determines that no access path exists and returns indication information indicating that path validation failed.

When it is determined that the access path does not exist, the alarm information may also be returned to prompt the operation and maintenance staff that the access path does not exist and that the access relationship information needs to be adjusted, which may be a problem in the node information provided in the access relationship information, for example, the number of nodes is too small, a key node is missing, and the like, so that no path exists.

By the scheme, the path nodes can be completed according to the incomplete access relation of the path node information in the access relation information, so that the corresponding complete access path is obtained, all the nodes on the access path and the information of the equipment where all the nodes are located are obtained, the access relation information without the access path can be fed back in time, the problem of the access relation of operation and maintenance personnel is prompted, and the operation and maintenance efficiency is improved.

The above scheme may be implemented by some databases and operation and maintenance management tools, for example, by an Access database, a task setting module, a controller and an operation and maintenance tool in combination with fig. 8, and the specific implementation manner may be: initializing the whole network topology information by calling a configuration file such as an InitController function, specifically initializing path information, equipment information, special line information and the like, and returning a Controller object containing the whole network topology information after initialization; storing access relation information through an access object, initializing the access object by calling a load _ access function, wherein the access object can be a class list object, each access object is an access relation, and screening a Controller object of the whole network topology information to respectively generate the whole network topology information corresponding to each access relation when each access relation is initialized; calling a task function to generate a configuration task of each access relation and a sub-configuration task of each device in a corresponding access path according to the full-network topological relation of each access relation through a task configuration task module; when configuration is performed, whether configuration is correct can be determined by whether a data packet output by a front node is consistent with a data packet input by a rear node in the same access path, for example, referring to an access relationship a2 illustrated in fig. 8, nodes Z1, Z3 and Z5 are involved, the access path is "Z1 → Z3 → Z5", a data packet output after passing through the Z1 node is the same as a data packet input to the Z3 node, a data packet output after passing through the Z3 node is the same as a data packet input to the Z5 node, and whether configuration of a certain device in a certain access relationship is successful can be determined by checking similarity of the data packets; the data packet information that will be encountered in the configuration task may be pre-entered into the corresponding access relationship information.

And finally, returning all the configuration task execution results. It should be appreciated that, when the operation and maintenance method provided by the present disclosure is actually executed, the database, the operation and maintenance tool, the plug-in, etc. for deploying the operation and maintenance method 200-700 may be determined according to the actual state of the database in the whole network, the model of the device, the type of the system, etc.
