Detailed Description
In the embodiment of the invention, an interface board (referred to as a target interface board herein) on a designated interface board slot position (referred to as a target interface board slot position herein) in a network communication device integrating a network board and a master control board is taken as a new master control board; the original main control board is used as a network board and is responsible for equipment information management, so that the main control board and the network board are separated under the condition of not changing the architecture of the network communication equipment, the stability of the equipment is improved, and the probability of message loss is reduced.
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for implementing a virtualization control board according to an embodiment of the present invention is shown in fig. 1, where the method for implementing a virtualization control board includes the following steps:
In the embodiment of the present invention, when the network Communication device is started, the network Communication device starts the network board first, and when an IPC (Inter-Process Communication) chip configuration of the network board is completed, that is, the interface board can communicate with the network board, and when the interface board can interact with each other through the network board, the start of the network board is suspended.
In the embodiment of the invention, in order to realize the separation of the main control board and the network board on the premise of not changing the existing architecture of the network communication equipment, a target interface board on the specified interface board slot position of the network communication equipment can be used as a new main control board.
Correspondingly, after the IPC chip configuration of the network board is completed and the start is suspended, the network communication equipment can start the target interface board.
After receiving the start instruction, the target interface board may execute a start flow, and after bootware (boot program) is loaded, the target interface board may obtain a master control board start file, load the master control board start file, and start with the role of the master control board, so that topology management, protocol calculation, and the like can be performed with the role of the master control board.
In one embodiment of the present invention, the obtaining, by the target interface board, the master control board startup file may include:
the target interface board sends a main control board starting file acquisition request to the screen board;
the network board receives a main control board starting file acquisition request sent by a target interface board and sends a main control board starting file to the target interface board.
In this embodiment, because the interface board does not have Flash (Flash memory) in the existing network communication device architecture, and the start-up files that need to be loaded by each board are stored in Flash of the web board when the device is started, in order to enable the target interface board to start up in the role of the main control board, the target interface board needs to obtain the main control board start-up file from the web board and load the obtained main control board start-up file.
In another embodiment of the present invention, when the target interface board has Flash and the Flash stores the main control board start file, the obtaining, by the target interface board, the main control board start file may include:
and the target interface board acquires the main control board starting file from the Flash.
In this embodiment, in order to improve the device start efficiency, the target interface board may be modified to have Flash, and the main control board start file is stored in the Flash of the target interface board. When the network communication equipment is started, the target interface board does not need to acquire the main control board starting file from the network board, but can directly acquire the main control board starting file from the Flash of the target interface board and load the acquired main control board starting file.
It should be noted that, in the embodiment of the present invention, when the target interface board has Flash, the start file that needs to be loaded when the interface board starts can also be stored in Flash of the target interface board, and at this time, other interface boards (interface boards on other interface board slot positions than the target interface board slot position) other than the target interface board can obtain the software that needs to be loaded from the target interface board; or, the start file to be loaded when the interface board starts can still be stored in the screen board, and at this time, other interface boards can still obtain the start file to be loaded from the screen board.
In addition, in the embodiment of the invention, the target interface board is used as a new main control board; the original network board in the network communication device architecture needs to be started in an interface board mode when the device is started.
Whether the specific starting file is obtained from the Flash of the target interface board or the Flash of the screen board, the specific starting file can be determined by the way of appointing the file name of the starting file in advance or the file type of the starting file in the concrete implementation.
In the embodiment of the invention, after the target interface board is started, the network communication equipment can continue to start the network board so as to complete the initialization process.
And step 104, when the network communication equipment is started, the target interface board acquires the configuration file and issues the configuration file.
In the embodiment of the invention, the target interface board is used as a new main control board of the network communication equipment, so that the target interface board can also acquire the configuration file and issue the configuration file when the network communication equipment is started. For example, for port-based configuration, a configuration file is issued to an interface according to an interface board to which the port belongs; for configuration based on global situation, the specific implementation of sending the configuration file to all boards and the like may refer to the related implementation of issuing the configuration file by the main control board in the existing related scheme, which is not described herein again in the embodiments of the present invention.
In an embodiment of the present invention, the obtaining, by the target interface board, the configuration file may include:
the target interface board sends a configuration file acquisition request to the screen;
the network board receives a configuration file acquisition request sent by a target interface board and sends a configuration file to the target interface board.
In this embodiment, when the target interface board does not have Flash, the configuration file still needs to be stored in Flash of the web board.
Correspondingly, when the network communication equipment is started, the target interface board can acquire the configuration file from the Flash of the network board and issue the configuration file.
In another embodiment of the present invention, the obtaining, by the target interface board, the configuration file may include:
and the target interface board acquires the configuration file from the Flash.
In this embodiment, when the target interface board has Flash and the Flash stores the configuration file, the target interface board can directly obtain the configuration file from the Flash and issue the configuration file.
It should be noted that, in the embodiment of the present invention, in order to improve the processing performance of the target interface board when the target interface board is used as the main control board, in addition to adding Flash to the target interface board as described above, a Central Processing Unit (CPU) with stronger processing performance may be replaced for the target interface board, or/and the memory size of the target interface board is increased; in addition, considering that the target interface board does not need to be responsible for flow forwarding after being upgraded to a new main control board, the switching chip of the target interface board can be removed, so as to reduce the cost of the target interface board.
It can be seen that, in the method flow shown in fig. 1, by upgrading the interface board at the designated interface board slot to a new master control board, the original master control board serves as a network board and is responsible for device information management, thereby achieving separation of the master control board and the network board without changing the architecture of the network communication device, improving the stability of the device, and reducing the probability of message loss.
Further, in the embodiment of the present invention, in order to improve the reliability of the device, the number of the target interface board slots may be multiple (two or more), that is, the number of the target interface boards supported by the network communication device is multiple.
Correspondingly, the loading of the main control board starting file by the target interface board comprises the following steps:
when the IPC chip configuration of the target interface board is finished, performing main target interface board election with other target interface boards on other appointed interface board slot positions, and executing a starting flow according to election results in a main target interface board or standby target interface board mode;
the target interface board acquires the configuration file and issues the configuration file, and the method comprises the following steps:
and when the target interface board is selected as the main target interface board, acquiring the configuration file and issuing the configuration file.
In this embodiment, when the network communication device is deployed with a plurality of target interface board slots, and the target interface board completes the IPC chip configuration by loading the main control board start file, before continuing to execute the start procedure, it needs to determine whether other target interface boards are inserted into other target interface board slots. For example, the target interface board may determine whether another target interface board is inserted into the slot of another target interface board by obtaining the in-place information of the slot of another target interface board from the network board.
In this embodiment, when the target interface board determines that other target interface boards are inserted into other target interface board slots, the target interface board can perform an active target interface board election with the other target interface boards.
Specifically, a target interface board may forward an election packet to another target interface board through a network board, and receive the election packet forwarded by another target interface board through the network board, where the election packet carries a slot or other identification information where the target interface board that sent the election packet is located.
After receiving the election messages of other target interface boards, the target interface board can conduct primary target interface board election according to the slot position information or other identification information carried in the election messages.
For example, the main target interface board can be selected by using the target interface board with the smallest (or largest) slot number of the slot position of the target interface board as the main target interface board.
After the target interface board and other target interface boards finish the main target interface board election, the starting process can be continuously executed according to the election result.
When the target interface board is selected as the main target interface board, the target interface board can execute the starting process in the manner of the main target interface board, and the specific implementation can refer to the starting process of the main control board in the existing related scheme; when the target interface board is not elected as the main target interface board, the target interface board may execute the start-up flow in a manner of the standby target interface board, and the specific implementation thereof may refer to the start-up flow of the standby main control board in the existing related scheme.
It should be noted that, when the target interface board determines that no other target interface board is inserted into the slot of the other target interface board, the target interface board may default itself to be the main target interface board, and execute the subsequent flow in the manner of the main target interface board.
In this embodiment, when the target interface board is elected as the main target interface board, the target interface board may obtain the configuration file and issue the configuration file when the network communication device is started.
Further, in this embodiment, when the target interface board is the primary target interface board, after the target interface board obtains the configuration file and issues the configuration file, the method may further include:
when receiving a management information acquisition request aiming at the target hardware equipment, acquiring the management information of the target hardware equipment from the network board, and sending the acquired management information of the target hardware equipment to a request sending party.
In this embodiment, the target hardware device does not refer to a fixed hardware device, but may refer to any hardware device whose information is managed by the main control board, such as a power supply, a fan, and the like.
In this embodiment, because the network communication device is limited by hardware, and the management information of the hardware devices such as the power supply and the fan is stored on the main control board (i.e. the network board), if the target interface board is used as the main target interface board, when the target interface board receives a management information acquisition request of the target hardware device, for example, a user requests to acquire the management information of the target hardware device by inputting a command line, or a user requests to acquire the management information of the target hardware device by using management software, the target interface board may acquire the management information of the target hardware device from the network board and send the acquired management information of the target hardware device to the sender.
Further, in this embodiment, when the target interface board is the primary target interface board, after the target interface board obtains the configuration file and issues the configuration file, the method may further include:
when receiving the single board plugging notification message sent by the network board, performing single board plugging processing.
In this embodiment, because the board plugging signal is generally only logically sensed and processed by the main control board (i.e. the web board), but due to hardware limitations, the target interface board lacks relevant hardware information after being upgraded to a new main control board, and the board plugging signal can still only be logically sensed by the web board and notified to the target interface board, for example, the web board notifies the target interface board of the board plugging signal through an IPC (Inter-process communication) message.
Correspondingly, when the web board senses a single board plugging signal, a single board plugging notification message can be sent to the target interface board; when the target interface board receives the single board plugging notification message sent by the web board, the single board plugging processing can be performed.
For example, when a new board is inserted, corresponding configuration information may be issued to the newly inserted board; when a board is pulled out, deleting the relevant configuration of the corresponding board, for example, the port configuration for the board, which may be specifically implemented by referring to the processing implementation of the main control board on the board plugging/unplugging signal in the prior art, which is not described herein again in the embodiments of the present invention.
Further, in this embodiment, when the target interface board is a standby target interface board, the method may further include:
when receiving the main/standby switch notification message sent by the network board, the main/standby switch processing is performed.
In this embodiment, similar to the single board plugging signal, the main/standby switching signal also needs to be sensed by the web board logic and notified to the target interface board.
When the network board senses the main/standby switching signal, the network board can send a main/standby switching notification message to the target interface board; and when the target interface board is a standby target interface board and receives a main/standby switching notification message sent by the network board, performing main/standby switching processing.
For example, assuming that the network communication device only includes two target interface board slots, when the target interface board serving as the standby target interface board receives the main/standby switching notification message, the target interface board may directly switch itself to the main target interface board, and the specific implementation thereof may refer to the implementation of main/standby switching between the main control board and the standby main control board in the prior art, which is not described herein again in this embodiment of the present invention.
Assuming that the network communication device includes more than two target interface board slots, when a target interface board serving as a standby target interface board receives a main/standby switching notification message, a new main target interface board needs to be subjected to election with other standby target interface boards (if the standby target interface board exists), and when the election is a new main target interface board, main/standby switching processing is performed; and when the main target interface board is not selected as a new main target interface board, the main target interface board is kept as a standby target interface board.
In order to enable those skilled in the art to better understand the technical solution provided by the embodiment of the present invention, the technical solution provided by the embodiment of the present invention is described below with reference to a specific application scenario.

2. when the first target interface board (second target interface board) loads the main control board starting file to complete the IPC chip configuration, whether the second target interface board (first target interface board) is in place or not can be determined through the monitoring board, and if the second target interface board (first target interface board) is in place, main target interface board election is conducted;
in this embodiment, it is assumed that the first target interface board and the second target interface board are both in place, and the main target interface board election principle is that the target interface board with the smallest slot position number of the slot position of the target interface board is the main target interface board, that is, the first target interface board elects the main target interface board;
after the main target interface board is selected, the first target interface board continues to execute the starting process in the main target interface board mode, and the second target interface board continues to execute the starting process in the standby target interface board mode.
3. When the switch equipment is started, the first target interface board sends a configuration file acquisition request to the monitoring board; after receiving the request, the monitoring board reads the configuration file from the Flash and sends the configuration file to the first target interface board; after receiving the configuration file sent by the monitoring board, the first target interface board issues the configuration file;
4. when a first target interface board receives a display request of management information of hardware equipment such as a power supply/fan, the management information of the hardware equipment such as the power supply/fan is obtained from a monitoring board and is displayed on a specified function interface;
5. when the monitoring board senses a single board plugging signal, sending a single board plugging notification message to a first target interface board; when the first target interface board receives the single board plugging notification message sent by the monitoring board, the single board plugging processing is carried out;
6. when the monitoring board senses the main/standby switching signal, the main/standby switching notification message is sent to the second target interface board; when receiving the main/standby switching signal, the second target interface board switches itself to the main target interface board.
