Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.

Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As known from the background art, when a switch is started, the steps of starting a UBoot, loading an image file, initializing a switch chip, loading an upper application, and the like are required, and a two-layer forwarding function and a three-layer routing function can be normally used after the foregoing steps are completed. The starting process of the switch is complicated, the two-layer forwarding function and the three-layer routing function can be normally used only by waiting for several minutes, and the starting time of the switch is long.
Therefore, embodiments of the present invention provide a method and a system for starting a device, in which a function module with high relevance to a two-layer forwarding function and a three-layer routing function is stored in a master image file in advance, and other function modules are stored in a slave image file. When the switch is started, the UBoot is started, the main image file is loaded to start the two-layer forwarding function and the three-layer routing function in advance, and then the auxiliary image file is loaded to start other functions of the switch, so that the starting time of the switch is reduced.
Referring to fig. 1, a flowchart of a method for starting a device according to an embodiment of the present invention is shown, where the method includes the following steps:
step S101: and loading a preset UBoot image file and starting the UBoot.
It should be noted that UBoot is a program for booting the operating system, and the UBoot can move the operating system from the slow storage device to the fast storage device, so as to speed up the booting speed of the operating system.
It should be further noted that, the UBoot image file is reduced in advance according to the model of the switch, so that the volume of the UBoot image file is minimized.
The mode for simplifying the UBoot image file is as follows: and according to the model of the switch, determining a drive which is not used by the model, determining a function which is removed in the UBoot mode but does not influence the work of the switch in the operating system mode, and removing a drive file and a function which correspond to the drive which is not used from the UBoot image file, namely optimizing the UBoot program into a simplest image file on the premise of not influencing the UBoot function and the normal use of the switch.
That is to say, the simplified UBoot image file does not load unused drivers and functions, so that the speed of starting the UBoot is increased, and the starting time of the switch is shortened.
For example: for a certain model of switch, if the USB device is not used in the switch UBoot mode, the USB driver file in the UBoot image file is removed.
In the process of specifically implementing step S101, a preset UBoot image file is loaded, a plurality of driver files are obtained, drivers corresponding to the driver files are sequentially loaded, and a UBoot starting process is completed. Wherein the drive file is determined according to the model of the switch.
Step S102: and starting a two-layer forwarding function and a three-layer routing function of the switch by using the UBoot and the main image file.
It should be noted that the master image file includes: the system comprises operating system starting information, a plurality of high-priority functional modules and starting loading information of each functional module, wherein the high-priority functional modules are functional modules with high relevance with the two-layer forwarding function and the three-layer routing function.
Preferably, the master image file further comprises a part of necessary functional modules for initializing the switch, such as: a clock synchronization function module and a data synchronization function module of a high Precision Time Protocol (Precision Time Protocol).
It should be further noted that the start-up information of the operating system is optimized in advance, and the time required for starting up the operating system is reduced. The specific optimization mode is as follows: according to the specific application requirement of the switch, the unnecessary driver in the operating system is removed, namely, the unnecessary driver is not loaded when the operating system is started. For example: and if the switch does not use the rapid and the USB, removing the drive files corresponding to the rapid and the USB in the operating system.
And optimizing the upper application modules loaded by the operating system, and reducing the redundancy of each upper application module and the loading time of each upper application module on the basis of ensuring the functions of each upper application module.
And optimizing the starting process of the operating system, modifying the starting file for loading the upper application module according to the specific requirement of the switch, and deleting the unnecessary application module and the process of unnecessary application of a part of the unnecessary application modules in each upper application module, namely not loading the unnecessary upper application module.
In the process of implementing step S102 specifically, when the switch is powered on and started, the started UBoot is used to load the master mirroring file, and the second-layer forwarding function and the third-layer routing function of the switch are started preferentially. And loading a part of necessary function modules for initializing the switch.
Step S103: and decompressing a preset slave image file, and starting other functions of the switch according to the starting and loading information of each functional module in the master image file, so that the switch finishes the loading of all the functions.
It should be noted that the slave image file includes a plurality of low-priority functional modules, and the low-priority functional modules are functional modules having low relevance with the two-layer forwarding function and the three-layer routing function.
The low priority functional modules include, but are not limited to: a fan control function module, a temperature detection function module, a Web function module, and the like, where the aforementioned low-priority function modules for example are not related to the two-layer forwarding function and the three-layer routing function.
Correspondingly, various protocol files which are irrelevant to the two-layer forwarding function and the three-layer routing function are also included in the slave image file.
In the process of specifically implementing step S103, the slave image file is loaded by using the UBoot, and a low-priority function module set is obtained. And loading each low-priority function module by combining the start loading information of each function module in the master image file and utilizing the start loading information corresponding to each low-priority function module, starting other functions of the switch, and configuring the related information of the switch according to the protocol file in the slave image file to enable the switch to complete the loading of all the functions.
It will be appreciated that the set of low priority functional modules comprises a plurality of the low priority functional modules.
It should be noted that a dual file system is built in the switch in advance, the master image file is stored in the first file system, and the slave image file is stored in the second file system.
In the embodiment of the invention, the functional modules are respectively stored in the master mirror image file and the slave mirror image file according to the relevance of the functional modules, the two-layer forwarding function and the three-layer routing function. When the switch is started, the UBoot is started by using the simplified UBoot image file, the UBoot is used for loading the main image file to start a two-layer forwarding function and a three-layer routing function in advance, and then the UBoot is loaded to start other functions of the switch. The method realizes the prior starting of the two-layer forwarding function and the three-layer routing function when the switch is started, optimizes the starting process of the switch and reduces the starting time of the switch.

It is to be understood that the set of high priority functional modules includes: a plurality of said high priority functional modules.
As can be seen from the foregoing, the high-priority functional module is a functional module having a high association with the two-layer forwarding function and the three-layer routing function. To better explain the specific type of the high priority functional module, the following is exemplified.
