The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the process of implementing the technical solution provided in the embodiment of the present application, the inventor of the present application finds that, in order to solve the technical problem of how to guarantee normal operation of a service when a virtual device is abnormal, in the prior art, a manner of performing synchronous backup between a plurality of virtual devices is generally adopted, and when one of the virtual devices is abnormal, performing virtual device switching is performed to guarantee normal operation of the service.

The disadvantages of this prior art solution are: the configuration information is actively acquired by the slave physical device, and the master physical device does not know the configuration condition of the slave physical device. When the virtual device of the master physical device is abnormal, the virtual device on the slave physical device may not be started or configured, and at this time, the virtual device on the slave physical device cannot timely take over the work of the abnormal virtual device on the master physical device, and cannot perform backup in time.

In order to alleviate the above problem, embodiments of the present invention provide a virtual device configuration method and a network device. The following embodiments are provided to describe a virtual device configuration method and a network device according to the present invention.
Referring to fig. 1, fig. 1 is a block diagram illustrating a master card virtual device management system in a network device 10 according to an embodiment of the present invention. The network device 10 includes at least two master cards. Fig. 1 is a schematic diagram illustrating the network device 10 including two host cards (a first host card 100 and a second host card 200). The network device 10 may further include more master cards according to actual service requirements.
In this embodiment, the network device 10 further includes a plurality of service cards, where the master control card is used to construct a virtual device and is responsible for forwarding control of data; and the service card is responsible for the actual forwarding of the data message. The main control card and the service card can adopt physical board cards integrated by circuits, and the main control card and the service card can comprise resources such as a CPU, a memory, a magnetic disk and the like.
In this embodiment, the network device 10 may include, but is not limited to, a server, a router, a switch, a security gateway, a PC, and the like.

In this embodiment, the network device 10 may use, but is not limited to, a container technology, a hardware virtualization technology, a multi-process technology, and the like to construct a virtual device. Among them, the container technology is preferably adopted, and the container technology is a lightweight virtualization technology. The container technology can build the number of containers as required, and further can effectively improve the working efficiency. Compared with a hardware virtualization technology and a KVM (kernel virtual machine) technology, the container technology can share one operating system, and processing efficiency is higher. Among them, the Linux Container (Linux Container) based on the Linux system is one of the hottest Container technologies at present, which can provide isolation of name space and allocation of resources.
In the present embodiment, the following embodiments will explain the virtual device configuration method based on the Linux container technology. It should be noted that: the invention is not limited to the realization of the scheme based on the Linux container technology, and the scheme can also be realized based on a vxWorks operating system, a common multi-process technology or other lightweight container technologies.
In this embodiment, the following embodiments will be described in terms of a distributed network system based on a master control card and a standby control card, where: the present invention is not limited to the distributed network system, and a stackable network system and a centralized system are also applicable.
It will be appreciated that the architecture depicted in fig. 1 is merely illustrative and that network device 10 may include more or fewer components than shown in fig. 1 or may have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
The present invention provides a readable storage medium including a computer program. The computer program controls the network device 10 on which the readable storage medium is executed to perform the following virtual device configuration method.
First embodiment
The embodiment of the invention provides a virtual device configuration method. Referring to fig. 2, fig. 2 is a flowchart illustrating a virtual device configuration method according to a first embodiment of the present invention. The method is applied to the network device 10 described above. The following describes the flow of the virtual device configuration method in detail. The method comprises the following steps: step S110, step S120, and step S130.
In step S110, the first main control card 100 obtains a configuration command request for performing virtual device configuration.
Referring to fig. 1 again, in this embodiment, a configuration client process, a master virtual device management process of the network device 10, and a core processing process for performing centralized management and control on processes running in the network device 10 run in the first master control card 100.
Referring to fig. 3, fig. 3 is a flowchart illustrating sub-steps of step S110 shown in fig. 2 according to a first embodiment of the present invention. The step S110 includes a substep S111 and a substep S112.
And a substep S111, wherein the configuration client process obtains a configuration command request for performing virtual device configuration through a serial port.
In this embodiment, the network device 10 is communicatively connected to a client device, and a user may log in to the network device 10 through a client interface (e.g., securect, a piece of secure terminal configuration software) provided by the client device. The user informs the network device 10 of the virtual device configuration by inputting a configuration command request for the virtual device configuration at the client interface.
The user may perform corresponding virtual device configuration operations on the network device 10 according to the configuration command, such as virtual device creation, virtual device startup, virtual device shutdown, virtual device deletion, and the like.
In this embodiment, the client device may pass a configuration command request (e.g., create a virtual device: create vdev1) input by a user to the configuration client process via a serial port (serial interface, commonly referred to as COM interface).
And a substep S112, the configuration client process packages the configuration command request and sends the packaged configuration command request to the master virtual device management process.
In this embodiment, the configuration client process performs necessary encapsulation on the configuration command request and then sends the encapsulated configuration command request to the host virtual device management process.
In this embodiment, in order to save system resources as much as possible, the virtual device management process may be dynamically started, that is, the default states of the master virtual device management process and the slave virtual device management process are not started, and are started to perform service processing when needed. Therefore, when the configuration client process transmits the configuration command request, the virtual device management process may be in an un-started state, at this time, the core processing process may start the master virtual device management process and the slave virtual device management process first, and then the configuration client process sends the configuration command request to the master virtual device management process.
Step S120, the first master control card 100 performs first master control card virtual device configuration according to the configuration command request, and sends the configuration command request to the second master control card 200 when configuration is completed.
Referring to fig. 1 again, in this embodiment, the second master card 200 runs a slave virtual device management process of the network device 10.
Referring to fig. 4, fig. 4 is a flowchart illustrating sub-steps of step S120 shown in fig. 2 according to a first embodiment of the present invention. The step S120 includes a substep S121 and a substep S122.
And a substep S121, where the primary virtual device management process performs the configuration of the virtual device of the first master control card according to the configuration command request.
In this embodiment, the primary virtual device management process requests to perform the first master card virtual device configuration in the first master card 100 according to the configuration command. For example, assuming that the configuration command request received by the primary virtual device management process is create vdev1, the primary virtual device management process may create a container vdev1 for carrying a virtual device in the first master card 100 through a container creation interface provided by a Linux system.
And a substep S122, when the configuration is completed, sending the configuration command request to the slave virtual device management process by the master virtual device management process.
In this embodiment, when the configuration is completed, the master virtual device management process may send the configuration command request to the slave virtual device management process running on the second master card 200, so that the second master card 200 performs virtual device backup configuration.
In this embodiment, the virtual device management process in this embodiment adopts a master-slave design structure, which can be set to, but not limited to, a master-slave mode, and the like. The first main control card 100 may serve as a main control card, the virtual device management process running in the first main control card 100 may serve as a main virtual device management process of the network device 10, the second main control card 200 may serve as a slave main control card, and the virtual device management process running in the second main control card 200 may serve as a slave virtual device management process of the network device 10.
In this embodiment, after the first master card 100 sends the configuration command request to the second master card 200, the second master card 200 will perform virtual device backup configuration. Therefore, the virtual device backup configuration operation of the second master control card 200 as the slave master control card is triggered by the first master control card 100 as the master control card, and the first master control card 100 can manage and control the configuration operation of the second master control card 200, so that when the virtual device of the first master control card 100 is abnormal, the virtual device of the second master control card 200 can timely take over the work and timely backup.
Step S130, the second master control card 200 performs second master control card virtual device configuration according to the configuration command request, and sends a feedback message of completing configuration to the first master control card 100 when configuration is completed.
Referring to fig. 5, fig. 5 is a flowchart illustrating sub-steps of step S130 shown in fig. 2 according to a first embodiment of the present invention. The step S130 includes a substep S131, a substep S132, and a substep S133.
And a substep S131, performing, by the slave virtual device management process, the configuration of the virtual device of the second master control card according to the configuration command request.
In this embodiment, after receiving the configuration command request transmitted by the master virtual device management process, the slave virtual device management process may perform second master card virtual device configuration in the second master card 200 according to the configuration command request. For example, assuming that the configuration command request is create vdev1, the slave virtual device management process may create a container vdev1 corresponding to the configured container vdev1 in the first master card 100 in the second master card 200 through a container creation interface provided by a Linux system, so as to carry the virtual device on the second master card 200 through the container vdev 1.
In this embodiment, when the containers in the first master control card 100 and the second master control card 200 are created completely, the master virtual device management process and the slave virtual device management process may negotiate according to a preset negotiation rule, and negotiate a master-slave relationship between the two containers to determine a master container providing services to the outside. For example, as shown in fig. 1, for a container 1, the container 1 in the first master card 100 may serve as a master container for providing services to the outside, and the container 1 in the second master card 200 serves as a slave container; and the opposite for container 2. Wherein, by default, the container (vdev1) in the first master control card 100 is usually used as the master container for providing services to the outside.
In this embodiment, based on the same configuration command request, the second host card virtual device configuration operation performed on the second host card 200 needs to correspond to the first host card virtual device configuration operation performed on the first host card 100.
In this embodiment, a plurality of containers for carrying different types of virtual devices may be created in each of the first master card 100 and/or the second master card 200. The containers in the first master card 100 and the second master card 200 need to correspond to each other. For example, as shown in fig. 1, the master container 1 of the first master card 100 corresponds to the slave container 1 of the second master card 200, and the slave container 2 of the first master card 100 corresponds to the master container 2 of the second master card 200.
And a substep S132, when the configuration is completed, generating a feedback message of the completion of the configuration from the virtual device management process.
Substep S133, the slave virtual device management process sends the feedback message to the master virtual device management process.
In this embodiment, when the slave virtual device management process succeeds in configuration operation, the slave virtual device management process may generate a feedback message of completion of configuration, and send the feedback message to the master virtual device management process. And when the master virtual equipment management process receives the feedback message, the master virtual equipment management process can know that the slave virtual equipment management process is configured and ready and can take over the work at any time.
In this embodiment, the master virtual device management process and the slave virtual device management processes both adopt an autonomous principle, and each virtual device management process autonomously controls configuration operations (for example, creation, start, shutdown, deletion, and the like) of a virtual device on the master control card to which the virtual device management process belongs. Therefore, the virtual device management process has simple and efficient management performance, the involvement relationship between the master virtual device management process and the slave virtual device management process is reduced, the complexity of service processing is reduced, and the problems of processing performance reduction, errors and the like caused by excessive involvement relationship are avoided.
Referring to fig. 6, fig. 6 is a second flowchart illustrating a virtual device configuration method according to a first embodiment of the present invention. The method further comprises the following steps: step S140.
In step S140, the first master card 100 sends a notification message that the configuration is successful to the client device.
Referring to fig. 7, fig. 7 is a flowchart illustrating sub-steps of step S140 shown in fig. 6 according to a first embodiment of the present invention. The step S140 includes a substep S141 and a substep S142.
And a substep S141, generating a notification message of successful configuration by the master virtual device management process, and sending the notification message to the configuration client process.
In this embodiment, when the primary virtual device management process receives a feedback message sent from the secondary virtual device management process, the primary virtual device management process may generate a notification message that the configuration is successful, and send the notification message to the configuration client process.
And a substep S142, sending the notification message to the client device by the client configuration process, so as to inform the user of successful configuration through the client device.
In this embodiment, the configuration client process may send a notification message of successful configuration to the client device through the serial port, and the client device prompts the user that the operation is successful through the SecureCRT interface.
In this embodiment, the master virtual device management process generates a notification message of successful configuration only after confirming that both the master virtual device management process and the slave virtual device management process operate successfully. Therefore, the slave virtual device configured by the slave virtual device management process can be ensured to be in a ready state at any time, so that when the master virtual device is abnormal, the slave virtual device can take over the work of the master virtual device in time.
In this embodiment, if the configuration fails, the host virtual device management process may perform the configuration again, or generate and send a notification message of the failure of the configuration to notify the user, and wait for a further indication from the user.
Referring to fig. 8, fig. 8 is a third flowchart illustrating a virtual device configuration method according to a first embodiment of the present invention. After the step S110, the method further includes: step S150 and step S155. Step S150 and step S155 only need to be executed after step S110, for example, step S150 and step S155 may also be executed after step S140.
Referring to fig. 1 again, in the present embodiment, a main memory database management process is further executed in the first main control card 100.
Step S150, the primary virtual device management process sends the configuration command request to the primary memory database management process.
In this embodiment, after obtaining the configuration command request, the primary virtual device management process may send the configuration command request to the primary memory database management process.
Step S155, the main memory database management process saves the configuration command request.
In this embodiment, the main memory database management process is responsible for performing configuration serialization storage processing, and the main memory database management process may store the configuration command request in a database, so that the network device 10 can directly obtain the configuration command request from the database when being started next time, and automatically re-execute the configuration command request to complete the corresponding virtual device configuration operation. Therefore, the user does not need to input the configuration command request again, user operation is reduced, and user experience is improved.
Referring to fig. 9, fig. 9 is a fourth flowchart illustrating a virtual device configuration method according to a first embodiment of the present invention. The method further comprises the following steps: step S160 and step S165.
Step S160, when the network device 10 detects an abnormality, determining that the master virtual device management process of the first master control card 100 is a new slave virtual device management process of the network device 10.
Step S165, determining that the slave virtual device management process of the second master card 200 is the new master virtual device management process of the network device 10.
In this embodiment, the master-slave relationship between the master and slave virtual device management processes is not constant. When the network device 10 detects an abnormality (for example, a virtual device abnormality, a master control card abnormality, a key process abnormality of the master control card, or the like), master-slave switching processing is required. At this time, the network device 10 determines that the master virtual device management process of the first master control card 100 is a new slave virtual device management process of the network device 10. Determining that the slave virtual device management process of the second master card 200 is a new master virtual device management process of the network device 10.
