Description
Technical Field
The present invention relates to communications technologies, and in particular, to a method for starting a switch, and a storage medium.
Background
The switch can load various functional software when being started so as to realize various functions. For example, if the switch is started and the switch application software is loaded, the switch function is realized after the switch is started, and if the gateway application software is loaded, the gateway function is realized after the switch is started.
Currently, the mode of switching application software running on a switch is as follows: the switch is connected with the upper computer, and the configuration parameters of the bootstrap program are manually changed through an operation interface of the upper computer, so that the application software required to be operated is determined to be started next time. For example, if the gateway function needs to be implemented after the switch is started next time, the configuration parameters of the bootstrap program need to be changed into gateway parameters by the upper computer before the switch is started next time, and the bootstrap program automatically loads gateway application software according to the gateway parameters when the switch is started next time.
The manual configuration parameter modification method has the following defects: if the changed parameters are not stored in time after the configuration parameters of the bootstrap program are changed, the bootstrap program can not load corresponding software according to the changed parameters when the switch is started next time, and the loaded software is the original software. Moreover, manual modifications are prone to errors. The configuration mode through the operation interface of the upper computer is complex to operate.

S120, the central processing unit searches for target application software corresponding to the application software indication information in a pre-established information software comparison table, wherein the information software comparison table stores the corresponding relation between the application software indication information and the application software.
In this embodiment, the information software look-up table is established before the central processing unit obtains the application software instruction information provided by the operable device, and the information software look-up table is stored in the memory associated with the central processing unit. The application software indication information corresponds to the application software one by one. Optionally, the application software herein includes information of the application software and/or the application software itself, and the information of the application software includes a name, a version, a storage path, a number, and the like of the application software.
After the central processing unit obtains the application software indication information, application software corresponding to the application software indication information is searched in an information software comparison table stored in the storage. For convenience of description and distinction, the searched application software is referred to as target application software.
S130, the central processing unit loads target application software.

This embodiment is further optimized by defining the operable device as a switching device having at least one electrical contact, the "closed" of the contact indicating that the electrical contact is conductive, allowing current to flow; an "open" of the switch indicates that the electrical contact is non-conductive, creating an open circuit, not allowing current to flow. Each electronic contact is closed corresponding to one gear, for example, the first electronic contact is closed corresponding to the switch device in the "1 gear", the second electronic contact is closed corresponding to the switch device in the "2 gear", the third electronic contact is closed corresponding to the switch device in the "3 gear", if all the electronic contacts are not closed corresponding to the switch device in the reset gear.
Fig. 2 is a flowchart of a switch startup method according to a second embodiment of the present invention, including the following steps:
s210, when the switch is started, the central processing unit acquires the current gear of the switch device.
And S220, the central processing unit searches target application software corresponding to the current gear in a pre-established information software comparison table.
And S230, loading the target application software by the central processing unit.
For example, the central processor acquires the closed electrical contact and thus the current gear of the switching device.
The information software comparison table stores a correspondence between a gear and application software, for example, the 1 gear corresponds to gateway application software, and the 2 gear corresponds to Packet Transport Network (PTN) application software.
In some embodiments, the reset gear corresponds to a default application software, such as a switch application software.
In other embodiments, if the reset gear is acquired and the user is not considered to select the application software, the control prompting device prompts the user to operate the switch device and/or prompts the user to the application software corresponding to the indication information of each application software. Based on this, when the switch starts, central processing unit in the switch acquires switching device's gear, includes: when the switch is started, if the gear of the switch device is reset, the central processing unit controls the prompting device to prompt a user to operate the switch device and/or prompt the user to the application software corresponding to the indication information of each application software; the central processor reacquires the shift position of the switching device in response to the user's operation of the switching device. And if the non-reset gear of the switching device still cannot be acquired after the preset time, directly loading default application software.
Optionally, the prompting device may be a display screen or a speaker, and is connected to the central processing unit for prompting the user to operate the switch device under the control of the central processing unit.
In one application scenario, the switching device has a reset gear, a 1-gear and a 2-gear. In order to facilitate user operation and improve the friendliness of the switching device, the 'switch application software' is marked around the reset gear, the 'gateway application software' is marked around the 1 st gear, and the 'PTN application software' is marked around the 2 nd gear; alternatively, the prompting device prompts the user for the application software corresponding to each application software indication information (in this embodiment, the gear position of the switch device), for example, the prompting device is triggered, and the prompting device automatically plays the application software corresponding to each gear position. When the switch is powered off or in the normal operation process, a user can toggle the switch device to 1 gear, and then gateway application software is loaded when the switch is started next time; the user can also toggle the switch device to the 2 nd gear, and then the PTN application software is loaded when the switch is started next time; the user can also toggle the switching device to a reset gear, and the 'switch application software' will be loaded the next time the switch is started.
In another application scenario, the user toggles the switching device to the reset gear. When the switch is started next time, the prompting device can prompt a user to select application software, ask for dialing the switch device and/or the application software corresponding to each gear, and if the user dials the switch device to 1 gear or 2 gears within a preset time, the switch can load the corresponding application software; and if the user does not toggle the switching device to the 1 gear or the 2 gear within the preset time, the switch automatically loads the application software of the switch.
In the embodiment, when the switch is started, the central processing unit acquires the current gear of the switching device, searches the target application software corresponding to the current gear in the pre-established information software comparison table, and loads the target application software corresponding to the target application software, so that the switch can switch the application software according to the gear state of the switching device, but not configure parameters; for a user, the application software of the switch can be switched by shifting the switch device, configuration parameters of an upper computer do not need to be connected, and the configuration parameters do not need to be stored, so that the technical effect of conveniently and accurately switching the application software of the switch is achieved.
EXAMPLE III
The foregoing embodiments mainly focus on the process of the central processing unit loading the application software when the switch is started. Currently, after the central processing unit loads the application software, all forwarding parameters required by the application software are configured to the switch chip through the application software. And after all the forwarding parameters are configured, the switch is started. The existing switch starting method is slow, and on the basis of the above embodiments, in order to increase the speed of starting the switch, the embodiment provides a switch starting method, which can realize quick starting of the switch while switching application software conveniently and accurately. As shown in fig. 3, the method specifically includes the following steps:
and S300, powering on the switch and starting. Execution continues with S310 and S350.
And S310, when the switch is started, initializing and acquiring the access right of the switch chip by the microcontroller in the switch. Execution continues with S320.
In this embodiment, the microcontroller may be an STM32 chip, similar to a single chip microcomputer, and has a characteristic of fast initialization relative to a Central Processing Unit (CPU). Based on this, compared with the configuration operation of the switch chip executed by the central processing unit in the prior art, in the embodiment, the configuration operation of the switch chip is executed by the microcontroller with a faster initialization process, so as to save the starting time.
First, the microcontroller powers up and initializes its own clock, bus connector, etc., completing the initialization operation. Wherein, the exchange chip is respectively connected with the microcontroller and the central processing unit. After the microcontroller is initialized, acquiring the access right to the exchange chip, namely realizing the connection of the exchange chip and the microcontroller; meanwhile, the connection between the exchange chip and the central processing unit is disconnected.
And S320, the microcontroller acquires the basic forwarding parameters which are prestored and are required by the application software. Execution continues with S330.
The basic forwarding parameters that are common to the application software are, for example, basic forwarding parameters common to devices such as a switch, a gateway, and a PTN: rate duplexing of ports, forwarding state of ports, Virtual Local Area Network (VLAN) attributes of ports.
S330, the microcontroller configures the basic forwarding parameters into the switching chip. Execution continues with S340.
The basic forwarding parameters may be stored in a memory within the microcontroller or in a memory connected to the microcontroller. The memory can be nonvolatile memory such as ROM, FLASH, optical disk, floppy disk, mechanical hard disk, etc.
The basic forwarding parameters can be directly configured in the switching chip without the processes of state judgment and the like. Optionally, the microcontroller directly configures the acquired basic forwarding parameters into the switch chip via a bus between the microcontroller and the switch chip. At this point, the microcontroller completes the configuration operation of the switching chip.
And S340, releasing the access authority of the exchange chip by the microcontroller. And finishing the operation.
After the microcontroller completes the configuration operation of the exchange chip, the exchange chip is not configured any more, but the access authority of the exchange chip is transferred to the central processing unit, and the central processing unit accesses the exchange chip. Based on this, the microcontroller disconnects the connection with the exchange chip and connects the exchange chip with the central processing unit. The central processor is a main processor of the switch and is used for processing all the functional items of the switch.
In the embodiment of the invention, as soon as the switch is powered on, the microcontroller starts to configure the basic forwarding parameters to the switching chip, the microcontroller and the central processing unit of the switch are mutually independent, the microcontroller does not need to participate in the central processing unit of the switch for any operation of the switching chip, the basic forwarding parameter configuration of the switching chip is not needed to be obtained by running the SDK, and the basic forwarding parameters of the switching chip can be configured without waiting for a series of processes such as state judgment in the SDK, so that the quick start of the switching chip is realized.
And S350, when the switch is started, the central processing unit in the switch acquires the application software indication information provided by the operable device. Execution continues with S360.
And S360, the central processing unit searches the target application software corresponding to the application software indication information in a pre-established information software comparison table, wherein the information software comparison table stores the corresponding relation between the application software indication information and the application software. Execution continues with S370.
And S370, the central processing unit loads the target application software. Execution continues with S380.
Specifically, when the switch is started, the central processing unit is powered on first and completes initialization. Then, the central processor obtains the application software indication information provided by the operable device through the bootstrap program, and searches and loads the target application software.
It is noted that S310-S340 are performed sequentially, and S350-S370 are performed sequentially. S310-S340 and S350-S370 are performed independently without interference. Generally, because the initialization process of the microcontroller is faster than that of the central processing unit and the operating system and the application software do not need to be loaded, the microcontroller already releases the access right to the switching chip before the central processing unit loads the target application software. Then, the central processing unit continues to execute S380.
S380, the central processing unit obtains the access authority of the exchange chip and configures other parameters, except the basic forwarding parameters, required by the target application software into the exchange chip. And finishing the operation.
Optionally, after the central processing unit loads the application software, the application software configures other parameters except the basic forwarding parameter into the switch chip according to the configuration parameter requirement of the application software, that is, the switch chip is configured perfectly by the target application software.
Since the basic forwarding parameters are already configured in the switch chip, if the application software continues to configure the basic forwarding parameters in the switch chip, the configuration will be repeated, and network interruption will be caused. In order to solve the above problems, the configuration parameter requirements of the application software are changed, specifically, the basic forwarding parameter requirements are deleted or skipped in all the configuration parameter requirements, so that the application software does not configure the basic forwarding parameters any more, and only configures other parameters, thereby avoiding network interruption.
Optionally, if the central processing unit loads PTN application software, other parameters of the PTN application software include configuration parameters related to Multi-Protocol Label Switching (MPLS) service, and the like; if the central processing unit loads gateway application software, other parameters of the gateway application software comprise forwarding strategy configuration parameters and the like; if the central processor loads the switch application software, other parameters of the switch application software comprise routing configuration parameters, multicast configuration parameters and the like.
In the embodiment, a microcontroller with fast initialization is newly added into the switch, and after the microcontroller is initialized, the access authority of the switch chip is acquired, so that the switch chip is configured by the microcontroller with fast initialization; obtaining a basic forwarding parameter which is saved in advance; configuring the basic forwarding parameters into the exchange chip, releasing the access authority to the exchange chip, and thereby directly configuring the pre-stored forwarding parameters into the exchange chip without application software configuration, and without waiting for table lookup and application software loading processes; in addition, in the process of configuring the exchange chip by the microcontroller, the participation of the central processing unit is not needed, and the process of loading the application software by the central processing unit and the process of configuring the exchange chip by the microcontroller are simultaneously carried out, so that the rapid starting of the switch is further realized.
In some embodiments, the switch further comprises a bus connector, the bus connector connecting the microcontroller, the switch chip and the central processor, respectively. The microcontroller acquires and releases the bus control right by issuing bus control parameters to the bus connector.
Optionally, the microcontroller acquires an access right to the switch chip, including: the microcontroller issues a first bus control parameter to a bus connector connected with the microcontroller, wherein the first bus control parameter is used for controlling the bus connector to be connected with the microcontroller and the switching chip and disconnecting the central processing unit and the switching chip.
Correspondingly, the bus connector is used for connecting the microcontroller and the switching chip and disconnecting the central processor and the switching chip according to the first bus control parameter.
Optionally, the microcontroller releases the access right to the switch chip, including: and the microcontroller issues a second bus control parameter to the bus connector, wherein the second bus control parameter is used for controlling the bus connector to be connected with the central processing unit and the switching chip and disconnecting the microcontroller from the switching chip, so that the central processing unit acquires the access right to the switching chip.
It should be noted that the present embodiment implements access right control through the hardware of the configurable bus connector, but is not limited thereto. Any software and/or hardware method capable of implementing bus control is within the scope of the present embodiments.
It should be noted that, when the microcontroller configures the switch chip, the bus between the central processing unit and the switch chip is cut off, and at this time, the central processing unit is executing the reading, table look-up and application loading operations of the application indication information, and does not access the switch chip in the above process. The microcontroller takes approximately 2-3 seconds to complete the configuration of the switch chip. In most cases, the above process of the central processing unit is longer than the configuration process of the switch chip, and after 2-3 seconds, the central processing unit completes the loading operation of the application software, is connected with the switch chip through the bus connector, accesses the switch chip, and then continues to configure other parameters. Based on the above analysis, the central processor will not sense the operation of the bus connector and will not sense the connection or disconnection with the switch chip.
In the embodiment, a bus connector is added in the switch, and the microcontroller acquires and releases the access right by issuing bus control parameters to the bus connector, so that a bus basis is provided for the configuration of the switching chip by the microcontroller and the access of the central processing unit to the switching chip after the configuration is completed; meanwhile, the microcontroller and the central processing unit can independently operate the exchange chip in different time periods through the acquisition and the release of the access authority; further, the connection or disconnection of the central processing unit to or from the switch chip is not sensed, and therefore, the connection or disconnection to or from the switch chip has little effect on the central processing unit.
