Description
Technical field
The present invention relates to network communications technology field, relate in particular to the Basic Input or Output System (BIOS) program in a kind of network equipment and the upgrade method of mainframe program.
Background technology
At present, the network equipment quantity of moving in network is more, and distributed more widely, and is therefore also very big to the maintenance workload of each network equipment.For reducing maintenance cost, progressively adopt pattern to manage by the management of Network Management Equipment remote centralized for various network device.As shown in Figure 1, need concentrate or utilize network remote login (for example telnet) that far-end or local network device are carried out maintenance management by Network Management Equipment usually, to reduce maintenance and maintenance cost.The management of the network equipment is comprised updating and management to software programs such as the mainframe program in the network equipment, BIOS (Basic Input or Output System (BIOS)) programs.
Described bios program is the program of at first moving after the network equipment starts, and as shown in Figure 2, the reflection of this program burns in EEPROM (electricallyerasable ROM (EEROM)) usually, can call in during operation to move or reside among the EEPROM in the internal memory and move.The effect of BIOS mainly is that guiding device starts, its major function of finishing has initialization CPU (central processing unit) register, configuration CPU, and the initialization of system hardware (for example initialization of serial ports, network interface) etc., at last the mainframe program file [as FLASH (flash memory), hard disk] from nonvolatile memory of certain format is read, with the reflection graftabl appointed positions of program, and will give mainframe program to the control of the network equipment.
Mode and form that mainframe program leaves on the nonvolatile memory are various, for example preserve by compression or unpacked format, preserve and alternative document breaks into bag and preserves or the like with document form or non-document form, wherein compression algorithm and packing form also can be varied.The mainframe program that moves in the internal memory must be deposited by the runtime host program image, and the bios program on the network equipment must be that runtime images and being encased in the internal memory moves from a certain format conversion with mainframe program.
In network equipment operational process, may need upgrade to the mainframe program that moves in the network equipment because the increase of network equipment function changes or remedies corresponding defective.Mainframe program upgraded realize remote upgrade on the long-range nonvolatile memory that is loaded into the network equipment of mainframe program after upgrading by TFTP (TFTP) and FTP (file transfer protocol (FTP)) usually.Support remote upgrade to need the network equipment that functions such as Telnet, ftp server are provided, the bios program function is limited, can't realize these functions, and functions such as therefore corresponding Telnet, ftp server need realize in mainframe program usually.
That is to say, for realizing remote maintenance management and remote software upgrade at the network equipment, each network equipment need be realized TFTP or File Transfer Protocol and TELNET agreement in its mainframe program, the control command of Network Management Equipment is by the TELNET agreement operated from a distance network equipment, or NMS user is remotely logged on the network equipment by the various command remote operation apparatus.By TFTP or File Transfer Protocol, the mainframe program after NMS user will be upgraded is long-range to be loaded on the nonvolatile memory of equipment, and new mainframe program can override old mainframe program and preserve and also can preserve in addition.After the mainframe program upgrading, also need bios program can recognize new mainframe program if still can guarantee the normal operation of the network equipment, and after restarting the network equipment, mainframe program after will being upgraded by the bios program of the network equipment is encased in the internal memory and moves, and finishes the upgrading of host software.But owing to be subjected to the restriction of original mainframe program function, mainframe program that possibly can't long-range loading new is to nonvolatile memory, incompatible such as file system and the file system after the upgrading that original mainframe program is deposited, perhaps do not have file system originally and the aft engine program of upgrading has realized file system, information still needs deposit or the like by document form on the nonvolatile memory.
Even mainframe program is upgraded successfully; if mainframe program after the upgrading and original mainframe program location mode and form are incompatible; inconsistent such as compressed format; original bios program can't be discerned new mainframe program; will cause new mainframe program correctly can't being converted to runtime images is encased in the content and moves; therefore, for guaranteeing the mainframe program after bios program can be discerned upgrading, also need usually bios program is upgraded.At present, bios program is upgraded, the scene of need arriving is usually opened cover and is changed the BOOTROOM that is used to preserve bios program in the network equipment, this bios program upgrading mode wastes time and energy, upgrade cost is higher, and can't realize remote upgrade, can not satisfy the maintenance needs of centralized management.

Embodiment
Core of the present invention is to increase BIOS+ (Basic Input or Output System (BIOS) upgrading) program that is provided with in the network equipment, this program is used to realize the function that BIOS need upgrade and realize, comprise the mainframe program handled after the upgrading and the difference between original mainframe program, as location mode and stylistic difference etc., in addition also comprise and handle other new functions that need realize.
Described difference and new function comprise:
(1) the original host program directly leaves certain fixed address place of FLASH (flash memory) in, and during startup, bios program is directly moved in the internal memory to certain fixed position taking-up mainframe program of FLASH and moved; If as required, the position change that the mainframe program after the upgrading is deposited in FLASH, BIOS does not move if do not upgrade just can not correctly directly mainframe program be moved in the internal memory;
(2) former bios program is not realized the file management system function owing to be subjected to storage space ground restriction (it leaves among the BOOTROOM), and its Starting mode is to read the mainframe program operation to FLASH fixed address place; For the convenience file management, set up file system on FLASH now, mainframe program leaves in the file system, therefore, it is read and need be undertaken by the mode of operation of file system; Former like this bios program is if the mainframe program that just can not correctly read on the FLASH of not upgrading moves in internal memory;
(3) increase audit function if desired to mainframe program version licence, inconsistent if version sequence number of preserving in the mainframe program and operational outfit are preserved, will refuse to move mainframe program, and not have this function in the former bios program;
Comprise the multiple demand of above 3 kinds of demands in content, the present invention all can use a BIOS+ program and realize under the situation of not changing bios program.
The specific implementation of method of the present invention may further comprise the steps as shown in Figure 3:
Step 31: determine the mainframe program after the upgrading, set up the BIOS+ program, and this program is the program that original bios program can be discerned in the network equipment, thereby make that original bios program can be by the mainframe program after this BIOS+ procedure identification upgrading;
The program that described original bios program can be discerned is the program consistent with the form of original host program.
Step 32: the mainframe program after BIOS+ program and the upgrading is bound together, thereby be made into the file of the original host program form that original bios program can be discerned in the network equipment;
Wherein, the mainframe program binding mode after BIOS+ program and the upgrading can have multiple, for example the data field information of new mainframe program as the BIOS+ program can be bound together; If the original host program form is the integrated of a plurality of programs, BIOS+ program and new mainframe program can also be integrated by original form as subroutine; But need the principle of the binding followed to be in the binding procedure: former bios program can be discerned the BIOS+ program, and it can be encased in the operation of internal memory; Simultaneously, position that need the BIOS+ program is set to identical with the deposit position of original host program, so that former bios program can be carried out the BIOS+ program as the original host program;
With two kinds of concrete binding processing procedures is that example describes binding mode:
First kind of mode is for to bind together the data field information of new mainframe program as the BIOS+ program, be specially: make the mainframe program after the upgrading earlier, its form is not limited by former bios program, as long as the BlOS+ program can be discerned, mainframe program after the upgrading that will make as the code compile of the data (as an overall array) of BIOS+ program and BIOS+ program together then, be made into the executable instruction file, the BIOS+ program that promptly includes the mainframe program after the upgrading, thereby make former bios program can discern BIOS+ program after the binding and the mainframe program after the upgrading, simultaneously, also need to make the mainframe program deposit position after BIOS+ program and the upgrading after the binding identical with the deposit position of original host program;
The second way is for integrating as subroutine BIOS+ program and new mainframe program by original form, be specially: the mainframe program after compiling the BIOS+ program separately and upgrade at first respectively, and the executable instruction file of these two programs is compressed into two son files by certain compressed format, then with the file of these two son files by the synthetic big packet form of form of original big APMB package, wherein the deposit position of BIOS+ program son file and compressed format must be consistent with original host program son file, former like this bios program just can identify BIOS+ program son file, and can will read decompress(ion) and call in the internal memory as the original host program run.
Step 33: by original mainframe program in the network equipment (promptly the mainframe program before the upgrading) with on the long-range nonvolatile memory that is loaded in the network equipment of new program that is bound into of mainframe program after BIOS+ program and the upgrading, on FLASH (flash memory) or hard disk, so that the network equipment when starting, can be realized the updating operation at bios program and mainframe program;
Described loading can be long-range loading, also can then can realize long-range updating operation at bios program in the network equipment and mainframe program by long-range loading for this locality loads;
At this moment, for original bios program in the network equipment, the BIOS+ program can be equivalent to original mainframe program.
Step 34: when the network equipment restarts, original bios program is encased in the BIOS+ program in the internal memory and moves in the network equipment, as shown in Figure 4, at first the BIOS+ program is accessed from the FLASH/ hard disk and the RAM that packs into (random access memory) in, and move in the space of the original host program run of packing into;
Promptly in the BIOS+ program run, it at first finishes the function that bios program need be upgraded, handle new and old mainframe program (mainframe program after original mainframe program and the upgrading) then in location mode and stylistic difference, such as setting up file system, change location mode and the form etc. of new mainframe program on nonvolatile memory;
Mainframe program after the binding mode of mainframe program after described BIOS+ program and the upgrading is to upgrade is during as the data field information of BIOS+ program, because the position of BIOS+ program is identical with the original host program, therefore, directly according to original implementation, promptly the BIOS+ program can be called in internal memory and execution in this step;
When the binding mode of the mainframe program after described BIOS+ program and the upgrading integrates by the form of former bios program as subroutine for adopting, the concrete processing procedure of this step comprises: former bios program is handled mainframe program as one in the file of big packet form compression son file, when former bios program need call mainframe program and moves in internal memory, at first read the head of the file of big packet form, to obtain the position of mainframe program son file at the file of big packet form, information such as compressed format, from big APMB package, read out the mainframe program son file then and be pressed into the executable instruction file, be transferred in the internal memory and move by certain formal solution; In this step, former bios program be with the BIOS+ program as mainframe program, therefore, be transferred to the BIOS+ program in the file that the mainframe program that moves in the internal memory is described big packet form herein;
Like this,, carry out the function code that increases newly, can finish the new function that former bios program need increase, such as check to new mainframe program version licence in the BIOS+ program run stage; Handle new and old mainframe program then in location mode and stylistic difference, such as setting up file system, change location mode and the form of new mainframe program on nonvolatile memory, the mainframe program after will upgrading at last is encased in the internal memory and moves; For the mainframe program after the upgrading, the status of BIOS+ program and effect just are equivalent to the status and the effect of former bios program.
Step 35: finish the start-up course of which directs network equipment by the BIOS+ program, the mainframe program after the treated upgrading is encased in the space of mainframe program in the internal memory and moves;
That is to say that for the mainframe program after the upgrading, the BIOS+ program function is equivalent to former bios program function, promptly the mainframe program correspondence after BIOS+ program and the upgrading becomes through bios program and mainframe program after the upgrading;
Because original bios program has taken the space of mainframe program operation during with BIOS+ program graftabl, as shown in Figure 4, cause again the mainframe program after the upgrading to be encased in the space motion of the mainframe program of should packing in the internal memory, so the BIOS+ program needs to have the function that oneself is transported to a new memory headroom operation, thereby with a new space motion that oneself is transported in the internal memory, as shown in Figure 5, after the carrying, the BIOS+ program is in the space, high address in the internal memory, mainframe program after the upgrading is in the low order address space in the internal memory, as can be seen, finish at the updating operation of bios program in the network equipment and mainframe program.
Finish after the carrying copy function of BIOS+ program, in the BIOS+ program realizes, directly use function name to call and to jump to new memory address space operation; After the BIOS+ program run is intact, just can discerns and read out the mainframe program after the upgrading and be transferred in the internal memory and move, and no longer be subjected to the restriction of original bios program according to certain mode.
To the concrete processing procedure of carrying operation of BIOS+ program be described below:
Usually the program execution is depositing in sequence of follow procedure instruction, and its operation can be carried out relative redirect (promptly jumping to apart from the operation of present instruction somewhere) or absolute redirect (promptly jumping to certain fixed address place moves) according to carrying out different jump instructions.Among the present invention, the execution of programs of instructions of employing is the program of an absolute fix, that is to say that the destination address of the absolute jump instruction in this program is all definite, and this execution of programs of instructions must directly be loaded into specified location operation of internal memory; This assigned address, promptly the initial operation address of execution of programs of instructions is to be specified by the user when program compilation connects; The compiling connector of code is according to the initial operation of the target instruction target word of user's appointment address, and the programmed instruction of last generation is carried out absolute fix; When compiling connects the BIOS+ program, specifies the initial operation of a new target instruction target word address, make the memory headroom of BIOS+ instruction repertorie operation and memory headroom that mainframe program takies not overlapping, thereby guarantee that the BIOS+ program moves at a new address space.
Start address such as mainframe program operation is 0 * 1000, and the length of mainframe program is 0 * 40000, so we to specify the initial operation address of BIOS+ program be 0 * 45000, get final product greater than (0 * 1000+0 * 40000).When device start, former bios program is used as the BIOS+ program as mainframe program and is identified and be transferred to internal memory 0 * 1000 place operation, then during the BIOS+ program run, at first finish the basic configuration of hardware such as CPU, and then copy whole BIOS+ program image to 0 * 45000 place, jump to certain function place operation of BIOS+ program then.Because having specified initial operation address when compiling connects the BIOS+ program is 0 * 45000, so the later space, all absolute fixs to 0 of address * 45000 of inner all call functions of BIOS+ program.Instructing self copy to finish all instructions of preparing the redirect from first in the BIOS+ program must move original host program run space, promptly since the address space at 0 * 1000 place.This can not use relative address by all instructions of instructing self copy to finish to prepare the redirect (promptly bringing into operation self copy tailend from the BIOS+ program) from first and realizes, is the same because do not contain the result of the machine instruction of relative address where place, location operation in office.When writing this section code, to note wherein can not directly using function call, because the function call code can include the instruction of relative address after being compiled into machine instruction.
For example, copying instruction repertorie to 0 * 45000 function from 0 * 1000 and can adopt in following { } one section code to realize wherein, this section copy function code compile can not produce the instruction that comprises relative address after connecting, and the instruction after this section compiling connects can any position operation in internal memory.After finishing instruction self copy, calling the somewhere operation after a function jumps to copy at last, is 0 * 45000 owing to compile the start address of appointment when connecting, so the relative address that last function call is used is certain address with respect to 0 * 45000.
{
Unsigned int*uldestination=0 * initial the operation of 45000/*BIOS+ program address be 0 * 45000*/;
Unsigned int*ulsource=0 * initial the operation of 1000/* mainframe program address be 0 * 1000*/;
Unsigned int*uldstend=(0 * 45000+0 * 5000)/* BIOS+ program length be 0 * 5000*/;
while(uldestination＜uldstend)
*uldestination++＝*ulsource++；
}
(absEntry) (startType); / * jumps to relative 0 * 45000 absEntry function place operation,
AbsEntry is the function name of operation, and startType is for starting
Type parameter */
As can be seen, just can realize the BIOS+ program is copied to the function of new memory address space by the epimere instruction.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
