All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
As known from the background art, when the switch is started, the steps of starting UBoot, loading an image file, initializing a switching chip, loading an upper layer application and the like are needed, and after the steps are completed, the two-layer forwarding function and the three-layer routing function can be normally used. The starting process of the switch is complicated, the two-layer forwarding function and the three-layer routing function can be normally used only after waiting for a few minutes, and the starting time of the switch is long.
Therefore, the embodiment of the invention provides a method and a system for starting equipment, which stores a functional module with high relevance with a two-layer forwarding function and a three-layer routing function in a master image file in advance, and stores other functional modules in a slave image file. When the switch is started, UBoot is started, a main image file is loaded to start a two-layer forwarding function and a three-layer routing function in advance, and then other functions of the switch are started by a slave image file, so that the starting time of the switch is reduced.
Referring to fig. 1, a flowchart of a method for starting up a device according to an embodiment of the present invention is shown, where the method includes the following steps:
step S101: loading a preset Uoot image file and starting Uoot.
Note that UBoot is a program for booting an operating system, and UBoot can move the operating system from a slow storage device to a fast storage device, so as to increase the booting speed of the operating system.
It should be further noted that, the UBoot image file is simplified in advance according to the model of the switch, so that the volume of the UBoot image file is minimized.
The method for simplifying the UBoot image file is as follows: according to the machine type of the switch, determining unused drive of the machine type, determining the function of removing but not influencing the switch work in the operation system mode in the Uoot mode, removing the drive file and the function corresponding to the unused drive from the Uoot image file, namely optimizing the Uoot program into the simplest image file on the premise of not influencing the Uoot function and normal use of the switch.
That is, the reduced UBoot image file does not load unused drivers and functions, so that the speed of starting UBoot is increased, and the starting time of the switch is reduced.
For example: for a certain type of switch, the Uoot mode of the switch does not use the USB device, and then the USB driving file in the Uoot image file is removed.
In the specific implementation process of step S101, a preset UBoot image file is loaded, a plurality of driving files are obtained, and the driving corresponding to the driving files is loaded in sequence, so that a UBoot starting process is completed. And the driving file is determined according to the type of the switch.

It should be noted that the main image file includes: 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 primary mirror file further comprises part of the necessary functional modules for initializing the switch, for example: high-precision time protocol (Precision Time Protocol) clock synchronization function module, data synchronization function module and other function modules.
Further, the operating system startup information is optimized in advance, so that the time required for starting the operating system is reduced. The specific optimization mode is as follows: according to the specific application requirements of the switch, the unnecessary drive in the operating system is removed, namely, the unnecessary drive 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, reducing the redundancy of each upper application module and reducing the loading time of each upper application module on the basis of ensuring the functions of each upper application module.
Optimizing the starting flow 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 some unnecessary application flow in each upper application module, namely, not loading the unnecessary upper application module.
In the specific implementation process of step S102, when the switch is powered on and started, the UBoot that has been started is used to load the main image file, so as to preferentially start the two-layer forwarding function and the three-layer routing function of the switch. And loading a part of necessary functional 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 loading information of each functional module in the master image file so that the switch finishes loading of all functions.
It should be noted that, the slave image file includes a plurality of low-priority function modules, where the low-priority function modules are function modules with low relevance to 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, etc., and the aforementioned plurality of low priority function modules for example are independent of the two-layer forwarding function and the three-layer routing function.
Correspondingly, the slave mirror image file also comprises various protocol files irrelevant to the two-layer forwarding function and the three-layer routing function.
In the specific implementation process of 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 functional module by utilizing the starting loading information corresponding to each low-priority functional module in combination with the starting loading information of each functional module in the master image file, starting other functions of the switch, and configuring relevant information of the switch according to the protocol file in the slave image file so as to enable the switch to finish loading of all functions.
It is understood that the set of low priority functional modules includes 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 a first file system, and the slave image file is stored in a second file system.
In the embodiment of the invention, the functional module is respectively stored into the master image file and the slave image file according to the relevance between the functional module and the two-layer forwarding function and the three-layer routing function in advance. When the switch is started, UBoot is started by utilizing the reduced UBoot image file, the main image file is loaded by using UBoot, the two-layer forwarding function and the three-layer routing function are started in advance, and then other functions of the switch are started by utilizing the slave image file.
