Description
Technical Field
The present invention relates to the field of network communication technologies, and in particular, to a control method and apparatus, and a computer storage medium.
Background
The disaster recovery technology is that two or more sets of systems with similar functions are established in remote places at a distance. When the working system has disastrous events such as earthquake, fire and the like or major faults such as power failure and the like, the working system is switched to a disaster recovery system at a different place, so that a reliability mechanism for providing the application service is maintained.
Nowadays, a main data center of a plurality of enterprises has been operated for years, and application systems which need to be operated for a long time exist, and the application systems are often difficult to be redeployed in a disaster recovery data center due to the selection of an early construction technology and the lack of technical support of an original manufacturer, and even Internet Protocol (IP) addresses of a plurality of applications can not be reconfigured; enterprises may therefore employ cloud computing Physical system migration virtualization (P2V) technology to migrate these applications into the Virtual machines of disaster-tolerant data centers. The applications are the same IP addresses in the main data center and the disaster recovery data center; especially, due to the particularity of the applications on the data requirements, for example, the master application and the slave application of the master data center and the disaster recovery data center need completely identical message queues, and the applications adopt a mode of integrally copying a virtual machine, so that the application IP addresses of the disaster recovery data center and the master data center are consistent.
In the construction process of the main data center and the disaster recovery data center, a scene that the IP addresses of the two applications are the same exists. For such a scenario, a network layer may select a cross-center Virtual Router Redundancy Protocol (VRRP) of a convergence switch to solve the problem, but there still exists a corresponding defect at present, and on one hand, a newly-built disaster recovery data center may select a network device that is completely different from a main center, and thus, a cross-center VRRP cannot be implemented; on the other hand, when the ports of the two aggregation switches are all opened, the cross-center VRRP has the possibility of inconsistent back and forth paths when the service is accessed across the center, so that the service is blocked by the firewall.

For example, in the data center shown in fig. 1, in order to perform a disaster backup function, it generally includes two active data centers a and a disaster recovery data center B that are physically different, and each data center can respond to the access request of the external network through the respective gateway (gateway A or gateway B), in order to meet the business and data backup requirements between the primary data center a and the disaster recovery data center B, an extensible Virtual local area Network (VXLAN) is usually required to be arranged between the primary data center a and the disaster recovery data center B, the main data center A and the disaster-tolerant data center B form a two-layer network, the service access between the main data center A and the disaster-tolerant data center B is as in the same local area network, this results in the gateways of the primary data center a and the disaster recovery data center B also being connected to the same lan. In order to meet the requirements of backup, virtual machine migration and the like of the main data center a and the disaster recovery data center B, the main data center a and the disaster recovery data center B have the same requirement on IP addresses provided inside the data centers, which results in address conflict in the local area network. To resolve this conflict, cross-center access of services is currently achieved by selecting the VRRP of the aggregation switch at the network layer. In the cross-center VRRP, when a main data center A fails, a disaster recovery data center B takes over the work in time; however, at this time, the situation that the ports on both sides of the aggregation switch are all opened may occur, so that the back-and-forth paths are inconsistent when the service accesses across the center, and thus the service access is blocked by the firewall, and the success rate of the service access is low.
In order to solve the above technical problem, referring to fig. 2, an architectural schematic diagram of a data center network according to an embodiment of the present invention is shown, in fig. 2, including: the control device 201 is independent of the primary data center a and the disaster recovery data center B, and the control device 201 may be a real entity device using physical hardware as a carrier, or a virtual entity device without being installed on any physical hardware, such as a virtual device generated by software simulation using redundant network resources; the network device 202 is located inside the active data center a and the disaster recovery data center B, and the network device 202 may include, but is not limited to, a switch, a router, a firewall, and other devices. In addition, based on the data center network architecture example shown in fig. 2, the control device 201 is mainly used to remotely control the ports of the network devices 202 in the active data center a and the disaster recovery data center B to be opened or closed, and the opening or closing of the ports of the network devices 202 can implement disaster recovery switching of the network link between the active data center a and the disaster recovery data center B.
It should be noted that, the data center network architecture example shown in fig. 2 is only for more clearly illustrating the technical solution of the present invention, and does not constitute a limitation to the present invention, and as the network architecture evolves and a new service scenario appears, the technical solution provided by the present invention is also applicable to similar technical problems, as will be known by those skilled in the art.

It should be noted that, before adding the network device, the parameters need to be defined in advance. For defining the preset type of the network equipment, firstly, a name needs to be filled in for the equipment type, information such as an equipment manufacturer, an equipment type, an equipment model and the like needs to be filled in, and equipment version information and equipment type description are filling information; in addition, in the preset type, the condition that the equipment manufacturer, the equipment type, the equipment model and the equipment version are completely consistent is not allowed to occur; thus, the type corresponding to each subsequently added network device must belong to a predefined preset type. After the preset type of the network device is defined, preset operations can be defined for the network device, and the preset operations can include a preset operation for opening a port of the network device, a preset operation for closing the port of the network device, and the like; for defining preset operation of the network equipment, filling in an action name of the operation, describing the action of the operation and uploading a script corresponding to the operation; the operation corresponding script is composed of a series of commands of the network equipment, and the script can comprise parameters; the rollback action can be configured for each action of the operation, and the rollback action also needs to add a corresponding script, and parameters can be included in the script. After the preset operation of the network device is defined, an operation trigger for executing the preset operation is further defined for each preset operation; the trigger can be realized by a custom script or by selecting a default trigger; the default triggers comprise a ping health monitoring trigger, an SSH login trigger, a TCP port monitoring trigger and the like, the custom script trigger can compile a script, set the script to be executed at regular time, and judge whether the trigger takes effect or not by analyzing a return value executed by the script. Here, the predefined network device parameters are not limited to the definitions of preset types, preset operations, preset operation triggers, and the like, and embodiments of the present invention are not specifically limited; meanwhile, the embodiments of the present invention are not limited to the specific matters that need to be defined for each parameter.
After the pre-definition of the network device parameters is completed, the control device starts to add network devices, and at this time, each added network device can be configured according to the defined network device parameters, including the configuration of the port group information and the preset trigger policy set of each network device; the preset trigger policy set represents an association relationship among the ports of the network device, the preset operation of the network device and the preset operation trigger of the network device, and the ports corresponding to the network device can be conveniently controlled to be opened or closed subsequently based on the configured preset trigger policy set.
For the technical solution shown in fig. 1, in a possible implementation manner, the querying a trigger policy corresponding to the target port from a preset trigger policy set of the network device to which the target port belongs specifically includes:
acquiring a preset trigger strategy set of the network equipment to which the target port belongs; the preset trigger strategy set represents an incidence relation among a port of the network equipment to which the target port belongs, preset operation of the network equipment to which the target port belongs and a preset operation trigger of the network equipment to which the target port belongs;

and establishing an incidence relation between the operation corresponding to the target port and the operation trigger corresponding to the target port, and further acquiring a trigger strategy corresponding to the target port.
It should be noted that after the preset trigger policy set of the network device is obtained, an association relationship between the operation corresponding to the target port and the operation trigger corresponding to the target port may be established according to the operation corresponding to the queried target port and the operation trigger corresponding to the target port, that is, the trigger policy corresponding to the target port is obtained. Specifically, the association relationship among the port of the network device, the preset operation of the network device, and the preset operation trigger of the network device may be established by adding an actuator, or the association relationship among the port of the network device, the preset operation of the network device, and the preset operation trigger of the network device may be established by adding a network device cluster, which is not limited in the embodiment of the present invention.
For the technical solution shown in fig. 1, in a possible implementation manner, if the current state information satisfies the trigger policy, controlling the target port to perform an action according to an operation corresponding to the trigger policy specifically includes:
acquiring the priority of the target port as a high priority based on the port information of the target port;
when the current state information is a target port fault, controlling the target port to be closed;
and when the current state information is the fault recovery of the target port, controlling the opening of the target port.
For the technical solution shown in fig. 1, in a possible implementation manner, if the current state information satisfies the trigger policy, controlling the target port to perform an action according to an operation corresponding to the trigger policy specifically includes:
acquiring the priority of the target port as low priority based on the port information of the target port;
when the current state information is the port fault with high priority, controlling the target port to be opened;
and when the port with the current state information of high priority is recovered due to failure, controlling the target port to be closed.
It should be noted that, when configuring the port group information of the network device, configuring a priority value for at least one port of the network device may be included; and the larger the value, the higher the priority. The triggering policy for the port configuration of the network device is assumed to be: when the port with high priority is in fault, closing the port with high priority and opening the port with low priority; when the port with high priority is recovered from the fault, opening the port with high priority and closing the port with low priority; thus, when the priority of the target port is high, if the detected current state information is that the port has a fault, the target port executes a closing operation; if the detected current state information is port fault recovery, the target port executes opening operation; when the priority of the target port is low, if the detected current state information is that the port with high priority has a fault, the target port executes an opening operation; if the detected current state information is the port failure recovery with high priority, the target port executes the closing operation.
It should be further noted that, for a network device cluster, a priority value may also be configured for a network device in the network device cluster; and the larger the value, the higher the priority. In this case, the triggering policy of the port configuration of the network device is: when the network equipment with high priority fails, closing the network equipment port with high priority and opening the network equipment port with low priority; when the network equipment with high priority is recovered from the fault, opening a network equipment port with high priority, and closing a network equipment port with low priority; according to the trigger strategy configured by the network equipment port, the disaster tolerance switching of the equipment level can be realized.
For the technical solution shown in fig. 1, in a possible implementation manner, if the current state information satisfies the trigger policy, controlling the target port to perform an action according to an operation corresponding to the trigger policy specifically includes:
if the current state information meets the trigger strategy, logging in the network equipment to which the target port belongs;
sending an execution instruction to the network equipment to which the target port belongs; the execution instruction is used for instructing the network device to which the target port belongs to execute a script corresponding to the trigger policy, and the script is used for representing an operation corresponding to the trigger policy.
It should be noted that, the login network device can log in through a Secure Shell (SSH) protocol built in the control device; the SSH protocol is a security protocol established by the network working group of the IETF, and the SSH uses public key encryption to authenticate a remote computer, which can be used to protect data transmitted between a client and a server. When the current state information of the target port meets the trigger policy, the operation trigger corresponding to the target port is triggered, at this time, the network device can log in the network device through the SSH built in the control device and send an execution instruction to the network device, so that the network device executes the script corresponding to the operation trigger, and the execution of the script can implement the execution of the operation corresponding to the operation trigger, thereby implementing the opening or closing of the target port.
For the technical solution shown in fig. 1, in a possible implementation manner, after the controlling the target port to act according to the operation corresponding to the trigger policy, the method further includes:
acquiring action feedback information of the network equipment to which the target port belongs; wherein the action feedback message at least comprises a trigger reason of the operation and operation information of the operation;
and sending and prompting the action feedback message.
It should be noted that after the target port performs the operation of opening or closing, the trigger reason and the operation information of the operation may be collected, and then the collected trigger reason and operation information is sent to the communication system as the action feedback message of the target port, and then the action feedback message is sent to the monitoring terminal (such as a mobile phone of an operation and maintenance person, a personal computer, and the like) by the communication system in one or more modes of a mail, a short message, and a WeChat, and the operation and maintenance person is prompted to check the action feedback message, so that the operation and maintenance person can conveniently handle the abnormal condition in time.
After the network equipment is added, a network topology structure can be established and a display function is provided; therefore, for the technical solution shown in fig. 1, in a possible implementation manner, the method further includes:
establishing and displaying a network topology structure based on the added network equipment;
and after the target port is controlled to act according to the operation corresponding to the trigger strategy, updating the port state information corresponding to the network equipment to which the target port belongs in the network topology structure in real time.

The embodiment provides a control method, which is applied to a control device for remotely controlling network equipment ports in a main data center and a disaster recovery data center, and determines a target port from port group information of network equipment; inquiring a trigger strategy corresponding to the target port from a preset trigger strategy set of the network equipment to which the target port belongs; detecting current state information corresponding to the target port; if the current state information meets the trigger strategy, controlling the target port to act according to the operation corresponding to the trigger strategy; the disaster-tolerant switching of the network link can be realized by remotely monitoring the port state of the network equipment in the data center and controlling the opening or closing of the port, so that the service access with the same application IP address deployment of the main data center and the disaster-tolerant data center is met; meanwhile, a trigger strategy for opening or closing the target port can be flexibly configured, so that the control of the target port has flexibility; the present invention is applicable to a wide range of port control not only for network devices such as switches, routers, and firewalls, but also for arbitrary telnet devices.
Example two
Based on the same inventive concept of the foregoing embodiment, referring to fig. 4, a detailed flow of a control method provided by the embodiment of the present invention is shown, and based on the example of the data center network architecture shown in fig. 2, the detailed flow includes:
s401: predefining a preset type of the network equipment;
s402: predefining preset operation of the network equipment;
s403: predefining a preset operation trigger of the network equipment;
for example, taking the data center network architecture shown in fig. 2 as an example, for the network device 202 shown in fig. 2, the network device parameter information may be predefined, and includes three aspects: the preset type of the network equipment, the preset operation of the network equipment and the preset operation trigger of the network equipment.
First, a preset type of network device is defined, and each type of network device corresponds to a specific device manufacturer, device type, device model, and device version. When defining the preset type of the network equipment, filling a name for the type of the network equipment, wherein the information which needs to be filled comprises an equipment manufacturer, an equipment type and an equipment model, and the optionally filled information comprises equipment version information and equipment type description; the situation that four information of an equipment manufacturer, an equipment type, an equipment model and an equipment version are completely consistent in the types of the network equipment is not allowed; further, port group information may be added to the type of the network device, where the port group information includes information such as a port number, a port type, and a priority value of at least one port. After the type definition of the network device is completed, one or more additions of the type of network device may be made.
Secondly, after the preset type definition of the network device is completed, preset operations can be defined for the network device, including the closing operation of the network device port and the opening operation of the network device port. Thus, when defining the preset operation of the network device, the action name of the operation, the action description of the operation and the script of the uploading operation need to be filled in; wherein the script of operations is composed of a series of commands of the network device, and the script can include parameters. When a script contains a parameter, a corresponding parameter name needs to be added to the operation when the operation is defined. In addition, each operation can be further configured with a rollback operation, and the rollback operation also needs to add a script and also can include parameters; the script of the rollback operation and the script of the operation are defined the same.
And thirdly, after the preset operation definition of the network equipment is completed, defining an operation trigger corresponding to each preset operation. Here, the trigger can be realized by a custom script, and can also be realized by selecting a default trigger; the default triggers comprise a ping health monitoring trigger, an SSH login trigger, a TCP port monitoring trigger and the like, the trigger for customizing the script can compile the script, the script is set to be executed at regular time, and then whether the operation trigger takes effect or not is judged by analyzing a return value executed by the script, so that whether the operation corresponding to the operation trigger needs to be executed or not is determined.
S404: adding a network device based on the add instruction;
s405: configuring the network device based on the configuration instructions;
s406: adding an executor based on an add instruction;
s407: adding a cluster of network devices based on the add instruction;
it should be noted that, for step S406 and step S407, the steps may be implemented by step S405, and when configuring the network device, an association relationship between a port of the network device, a preset operation of the network device, and a preset operation trigger of the network device may also be configured; in addition, for the association relationship between the port of the network device, the preset operation of the network device, and the preset operation trigger of the network device, the association relationship may also be implemented by the actuator added in step S406, or by the network device cluster added in step S407, which is not specifically limited in this embodiment of the present invention.
For example, taking the data center network architecture shown in fig. 2 as an example, after the definition of the network device parameter information is completed, the network device 202 needs to be added to the control of the control apparatus 201; meanwhile, an actuator may be added to the control apparatus 201, and the actuator configures the operation required by the port of the network device and the operation trigger associated with the operation.
First, when adding network devices, each network device has its own name and description, and selects a corresponding type for the added network device from predefined preset types, that is, each added network device must belong to a predefined network device type. Further, a network device deployment type may also be selected, where the deployment type includes stand-alone deployment, active-standby deployment, stacked deployment, active-standby deployment, and the like. When adding network equipment, selecting a data center name and a network area name, and configuring a network equipment management port address, an equipment login account number, a password and port information of the network equipment; one network device may include one or more ports, and the port information configured for each port includes a port number, a port type, a priority value, and the like; in addition, for active/standby deployment, stack deployment, and dual active deployment, two device management addresses need to be configured, and each address corresponds to a specific physical device management port.
Secondly, after the addition and the configuration of the network equipment are completed, an actuator can be added to the network equipment; in the executor, one or more operations may be added for each network device, and each operation may set parameters, including setting parameters for a fallback operation corresponding to the operation; in order to facilitate the execution of the actuator, an associated operation trigger may be further set for each operation, and similarly, an associated rollback operation trigger may be set for a rollback operation of each operation; that is, in the executor, the configuration operation and the association relationship between the operation triggers are performed for the ports of each network device, that is, the corresponding trigger policy is configured for the ports of each network device; in this way, in the subsequent step, when the current state information of the port of the network device meets the trigger policy, the port of the network device may perform opening or closing of the port according to the operation corresponding to the operation trigger. In the embodiment of the present invention, one executor may add one or more network devices, one operation trigger may trigger multiple operations, and one operation may also be triggered by multiple operation triggers; the present invention is not particularly limited thereto.
It can be understood that after step S405, in addition to configuring, by the embodiment of the present invention, an association relationship among a port of a network device, a preset operation of the network device, and a preset operation trigger of the network device through an executor, the embodiment of the present invention may also configure, by a network device cluster, an association relationship among a port of a network device, a preset operation of a network device, and a preset operation trigger of a network device. Specifically, a network device cluster is added to the control device 201, and then network devices of different data centers are added to the network device cluster; one or more ports of each network device can form a port group, and then the port groups of different network devices are placed in a port group cluster; then controlling the opening or closing of the port by the following control method; referring to fig. 5, a detailed flow of another control method is shown, which is as follows:
s501: acquiring the priority corresponding to a target port group in a port group cluster;
s502: judging that the target port group has high priority;
s503: when the current state information of the target port group is a fault, controlling the target port group to execute a closing operation;
s504: when the current state information of the target port group is fault recovery, controlling the target port group to execute an opening operation;
s505: judging that the target port group has low priority;
s506: when the port group with the current state information of the target port group being high priority fails, controlling the target port group to execute an opening operation;
s507: and when the current state information of the target port group is the fault recovery of the port group with high priority, controlling the target port group to execute a closing operation.
For example, still taking the data center network architecture shown in fig. 2 as an example, a network device cluster may be added to the control apparatus 201, and then different network devices are added to the network device cluster; one or more ports of each network device are grouped into a port group, and the port groups of different network devices are then placed in a port group cluster. Priority values may be configured for port groups in a port group cluster; the larger the numerical value is, the higher the priority of the port group can be used as the active port, and the lower the priority of the port group can be used as the standby port. The method for determining the port group fault comprises that one port fault in the port group represents the port group fault, or all the ports in the port group fault represents the port group fault; the embodiments of the present invention are not particularly limited. After the port group cluster configuration is completed, under an initial condition, the port group with high priority is in an open state, and the port group with low priority is in a closed state. The triggering policy for the port group configuration of the network device is assumed to be: when the port group with high priority fails, closing the port group with high priority and opening the port group with low priority; when the port group with high priority is recovered from the fault, opening the port group with high priority and closing the port group with low priority; thus, when the priority of the target port group is high, if the detected current state information is that the port group has a fault, the target port group can execute a closing operation; if the detected current state information is port group fault recovery, the target port group executes opening operation; when the priority of the target port group is low priority, if the detected current state information is that the port group with high priority has a fault, the target port group executes opening operation; if the detected current state information is the failure recovery of the port group with high priority, the target port group executes the closing operation.
Further, for a network device cluster, a priority value may also be configured for a network device in the network device cluster; and the larger the value, the higher the priority; the network device with high priority is the main network device, and the network device with low priority is the disaster recovery network device. In this case, the triggering policy of the port configuration of the network device is: when the network equipment with high priority fails, closing the network equipment port with high priority and opening the network equipment port with low priority; when the network equipment with high priority is recovered from the fault, opening a network equipment port with high priority, and closing a network equipment port with low priority; and based on the trigger strategy configured by the network equipment port, the disaster recovery switching of the equipment level is realized.
S408: detecting current state information of a target port of network equipment;
s409: establishing and displaying a network topology structure corresponding to the network equipment;
s410: judging whether the current state information meets a trigger strategy or not;
s411: if the current state information meets the trigger strategy, controlling the target port to act according to the operation corresponding to the trigger strategy;
s412: sending and prompting the acquired action feedback message; wherein the action feedback message at least comprises a trigger reason of the operation and operation information of the operation;
s413: and updating the port state information corresponding to the network equipment to which the target port belongs in the network topology structure in real time.
For example, still taking the data center network architecture shown in fig. 2 as an example, after the addition and configuration of the network device are completed, the current state information of the target port of the network device is detected in real time, and once the control device 201 finds that the detected current state information meets the trigger policy, the operation trigger is triggered, and the specific operation corresponding to the operation trigger is executed; the operation and maintenance personnel can also trigger the operation trigger manually, so that the control device 201 executes the specific operation corresponding to the operation trigger; the embodiments of the present invention are not particularly limited. Assume that the trigger policy for the network device port configuration is: when the port with high priority is in fault, closing the port with high priority and opening the port with low priority; the priority of the current target port is low priority, so that when the port of which the current state information is high priority is detected to have a fault, the control device 201 can remotely control the target port to execute an opening operation; meanwhile, the method can also acquire action feedback information of the target port, and comprises the following steps: the port with low priority executes opening operation due to the fault of the port with high priority; then the communication system sends the action feedback message to a monitoring terminal (such as a mobile phone, a personal computer and the like of an operation and maintenance person) in one or more modes of mails, short messages and WeChat and prompts the operation and maintenance person to check, so that the operation and maintenance person can know whether the port of the network equipment acts on the spot without going to the site, and can timely handle abnormal conditions. In addition, when the network device is added, besides the type of the network device, the deployment type of the network device, such as single machine deployment, main deployed, stacked deployment, dual active deployment, and the like, is also configured, and the name of the data center, the name of the network area, the address of the device management port, and the like corresponding to the network device are also configured, so that a network topology structure is established, and the position of each network device and the port state information of the network device can be shown in the network topology structure; meanwhile, port state information corresponding to the network equipment to which the target port belongs in the network topology structure can be updated in real time according to the operation executed by the target port.
Through the embodiments, specific implementations of the foregoing embodiments are explained in detail, and it can be seen that through the technical solutions of the foregoing embodiments, the disaster recovery switching of the network link can be realized by remotely monitoring the port state of the network device in the data center and controlling the opening or closing of the port, and service access in which the application IP addresses of the active data center and the disaster recovery data center are deployed at the same time is satisfied.
