Description
Technical field
The present invention relates to technical field of the computer network, particularly a kind of method, system and master control borad and interface board of preserving hardware table item index.
Background technology
Data processing comprises the data processing of software view and the data processing of hardware view.Software mainly is responsible for generating being used for the control information of data processing, and carries out the data processing of software view.Those skilled in the art will know that, software is stored in the internal memory when carrying out, and reading of data is faster than reading of data from hardware from internal memory, therefore, for control information is carried out necessary demonstration and to data delete/can locate corresponding control information fast when revising, in software, also corresponding control information can be kept, promptly in internal memory, described control information will be preserved.
In order to improve the data-handling capacity of the network equipment, give hardware with the processing of data and finish and become a kind of trend.Based on this, software also is issued to hardware with the control information that generates, and the network equipment will at first be handled (or also comprising forwarding) by the hardware in the network equipment according to the control information that is stored in the hardware after receiving pending data.Hardware can not be handled, and for example needs packet is done deep analysis and processing, then needs to be handled by software sending software on these packets, perhaps handles by giving relevant hardware after the software processes again.Like this, will keep the needed control information of a cover deal with data in the hardware, and promptly preserve the described control information that is issued by software, what these control informations were concrete can be as fib table, and ARP table etc. are to instruct corresponding data processing.
In order to navigate to the corresponding control information of hardware fast, be specially a certain list item in the hardware controls information, as a certain list item in the ARP table, usually can preserve the index of hardware table item in the software.The position that comprises each list item in the control information that is stored in the hardware in the index, i.e. memory address in hardware.Software just can directly be determined the accurate position that this list item is preserved according to the index of the hardware table item of preserving in hardware.
In distributed network, often comprise a master control borad and some interface boards.Software in the master control borad promptly generates above-mentioned control information and preserves, and issues the hardware of many parts of described control informations to each interface board.Hardware on each interface board is preserved described control information with deal with data, and simultaneously, the software on the master control borad is also preserved the index of list item in the hardware.A kind of method of preserving hardware table item index under the distributed network in the prior art, can comprise for the ARP list item is an example as shown in Figure 1 with the control information:
Step 101: master control borad issues the ARP list item to each interface board.
Step 102: the ARP list item that each interface board distributes one section memory address storage master control borad to issue in hardware separately, and will comprise distribute the index of address and ARP list item corresponding relation to send to master control borad.
In this step, the ARP list item that some interface boards distribute one section hardware address to issue with storage separately.To comprise 3 interface boards in the distributed network is example, and establishing the first interface board hardware base address is A, and the relative address of the storage ARP list item that distributes on first interface board is a.Wherein the base address is the initial address of hardware store unit, and relative address is the address of calculating with respect to the base address, promptly is the address that benchmark 0 calculates with the base address.Like this, the described ARP list item original position of storing on first interface board is A+a.Similarly, establishing the second interface board hardware base address is B, and the relative address of the storage ARP list item that distributes on first interface board is b, and the original position that then described ARP list item is stored on second interface board is B+b; If the 3rd interface board hardware base address is C, and the relative address of the storage ARP list item that distributes on the 3rd interface board is c, the original position that then described ARP list item is stored on the 3rd interface board is C+c.
The hardware table item index of storing on the master control borad only need know that relative position gets final product, like this, when interface board is received the notice of interpolation/deletion/a certain list item of modification ARP that master control borad is sent, the relative position that comprises in only needing to notify adds that the base address of self hardware obtains the actual address in hardware, thereby carries out corresponding operating in this actual address.
The base address of above-mentioned distinct interface plate may be different, and because the memory address that the ARP list item of sending for master control borad distributes is distributed voluntarily by each interface board, therefore, the relative address of the described ARP list item of storage also may be different on the distinct interface plate.
In this step, each interface board is also with index, promptly the ARP list item with in interface board on the hardware memory address corresponding hardware table item index send to master control borad.Concrete, can be each interface board sends to master control borad with the ARP list item stored on its hardware and the corresponding relation of relative address.
Step 103: master control borad distributes one section memory headroom to store the hardware table item index that each interface board is sent respectively for each interface board.
Owing to the relative address in the hardware table item index of issuing master control borad on the distinct interface plate in the abovementioned steps and the corresponding relation of ARP list item may be different, therefore, the different hardware table item index that these distinct interface plates can not be sent of master control borad is stored in the same internal memory.Like this, in this step, master control borad need distribute one section independent memory headroom for each interface board, in order to store the hardware table item index that each interface board is sent respectively.Position relation in the ARP list item place hardware of storing in the hardware table item index of each interface board of storing in the master control borad and each interface board can be as shown in Figure 2.

Embodiment
The invention provides a kind of method of preserving hardware table item index, master control borad is that control information distributes identical hardware table item index in each interface board hardware, and stores described control information and hardware table item index in internal memory; Master control borad sends described hardware table item index and each interface board is arrived in described control information; The control information that interface board receives according to the appropriate address storage of the hardware table item index that receives in interface board hardware.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Fig. 3 shows the method embodiment that the present invention preserves hardware table item index, as scheming:
Step 31: master control borad is that control information distributes identical hardware table item index in each interface board hardware, and stores described control information and hardware table item index in internal memory.
Described hardware table item index comprises the memory address of described control information in interface board hardware.
In this step,, be control information and in each interface board hardware, be assigned as and be stored in identical relative address for control information distributes identical hardware table item index in each interface board hardware.
Different interface boards, although hardware base address difference, the control information that but master control borad can be issued is stored in the identical relative address, and the hardware index address of storing in the master control borad internal memory only need be preserved the relative address of each interface board control information stored and the corresponding relation of control information, therefore, when control information that each interface board issues master control borad is stored in the relative address identical in the corresponding hardware, the hardware index address of each interface board is identical, and master control borad can only be preserved so a hardware index address.
In the prior art, owing to preserve by each interface board, and to be each interface board just preserve respectively after receiving the control information that master control borad sends, and when a certain interface board is preserved described control information, when to be a certain interface board with described control information be stored in the hardware a certain relative position, way does not learn other interface board is stored described control information in what kind of relative position, certainly so just can't guarantee also that each interface board stores described control information in identical relative position, and then master control borad can't be with the different hardware table item index of same section memory distinct interface plate correspondence.
In this step, the address of distributing storage control information in each interface board hardware by master control borad, concrete is the relative address of distributing storage control information in each interface board hardware, then master control borad can distribute identical relative address, like this, control information is stored in identical relative address in each interface board hardware, and master control borad unified distribution control information in each interface board hardware relative address and the corresponding relation of control information be hardware table item index, therefore, control information has identical hardware table item index in each interface board hardware.Like this, because the hardware table item index of each interface board is identical, so master control borad only needs one section internal memory to come the storage hardware table item index, just can pass through the control information in the quick location hardware of this hardware table item index.
It is to be noted, in distributed network equipment, each interface board can be to have defined identical hardware store scope for identical control information, be with identical relative address range storage control information on each interface board, and, such relative address scope master control borad also can be known, it for example can be the corresponding relation that a module stores on the master control borad has this class control information relative address on interface board, in this case, master control borad can directly obtain this relative address scope, therefore do not need interface board to report and to distribute address realm, but master control borad directly issues control information and hardware table item index.Like this, the hardware table item index of issuing each interface board is identical, and then each interface board is according to identical hardware table item index storage control information, therefore can be with the hardware table item index of one section memory corresponding to each interface board on master control borad.
In prior art, all to store with one section independent internal memory by master control borad for the distinct interface plate, just have under the situation of a lot of interface boards, prior art need adopt the multistage internal memory to store the hardware table item index of each interface board respectively, and this method of salary distribution in the present embodiment can make master control borad only adopt one section internal memory to store the hardware table item index of each interface board.Therefore, this method of the present invention embodiment can save the memory headroom in the master control borad greatly.
Master control borad in this step is that control information distributes identical hardware table item index in each interface board hardware, and the distributed relative address scope that can report according to each interface board for master control borad is that control information distributes identical hardware table item index in each interface board hardware.Concrete, master control borad is in the common factor of the distributed relative address scope that each interface board reports, for control information distributes identical hardware table item index in each interface board.Like this, this step comprises following substep:
Step 311: master control borad receives the hardware separately that each interface board reports respectively can distribute the relative address scope.
Step 312: master control borad determines that the hardware that each interface board reports can distribute the common factor of relative address scope.
Step 313: master control borad can distribute in the common factor of relative address scope at the hardware that each interface board reports, for control information distributes identical hardware table item index in each interface board.
This method of salary distribution, can guarantee that each interface board adopts the identical described control information of relative address range storage, the relative address scope that has yet guaranteed storage control information in the hardware table item index that master control borad distributes can not be the scope that has taken on the interface board, thereby guaranteed the performance of interface board integral body, also avoided owing to the problem that comprises the distribution failure that can't addresses distributed causes in the relative address scope of distributing.
Moreover, for the identical situation of memory range that defines for identical control information on each interface board, be with the situation of identical relative position storage control information on each interface board of similar front, if do not preserve the corresponding relation of memory range on this control information and the interface board on the master control borad, then need report this memory range by interface board.But,, therefore only need report hardware can distribute the relative address scope to get final product, and not need each interface board all to report by an interface board owing to store with identical relative position on each interface board.Certainly, do not get rid of and be still the mode that each interface board reports distributed relative address scope separately under this situation.
Step 32: master control borad sends described hardware table item index and each interface board is arrived in described control information.
Concrete, master control borad can adopt the method for synchronization or asynchronous system that hardware table item index and control information are sent to each interface board.After one skilled in the art will appreciate that asynchronous system is meant that master control borad is notified interface board with control information, do not wait for the feedback result of interface board, continue to do other actions, and interface board reinforms master control borad after finishing under the list item brush.After the method for synchronization is meant that master control borad is notified interface board with control information, waits for and brush the return results that finishes under the interface board, just continue to do other actions.
Step 33: the control information that interface board receives according to the appropriate address storage of the hardware table item index that receives in interface board hardware.
In this step, still for example control information is the ARP list item, and three interface boards are arranged, and the first interface board base address is A, and the second interface board base address is B, and the 3rd interface board base address is C.The relative address of establishing the master control borad distribution simultaneously is from d, and then the ARP list item of storing in ARP list item of storing in the master control borad internal memory and hardware table item index and each the interface board hardware can be as shown in Figure 4.In Fig. 4, the hardware table item index that first interface board issues according to master control borad, the ARP list item is stored in the initial position of A+d in its hardware, similarly, second interface board is stored in the initial position of B+d in its hardware with the ARP list item, and the 3rd interface board is stored in the initial position of C+d in its hardware with the ARP list item.
Like this, master control borad is that control information distributes identical hardware table item index in each interface board hardware, and store described control information and hardware table item index in internal memory, only need can store the hardware table item index of each interface board, thereby save internal memory greatly with one section internal memory.
Further, each interface board can report a part of hardware separately can distribute the relative address scope, rather than whole separately hardware can distribute the relative address scope.Certainly, if each interface board for the identical hardware relative address memory range of identical control information definition, then master control borad also can receive a part of hardware that an interface board reports once more and can distribute the relative address scope.This is significant in real system.Those skilled in the art will know that, address realm in the hardware is limited, if can distribute address realm all to report master control borad on whole hardware in the present invention, then when interface board receives other task, the hardware that interface board may occur can distribute the not enough situation of address realm, thus the ability drop that causes interface board to be executed the task.Therefore, each interface board reports a part of hardware separately can distribute the relative address scope, master control borad can distribute in the common factor of relative address scope at a part of separately hardware that each interface board reports, for control information distributes identical hardware table item index in each interface board.The a part of separately hardware that reports at each interface board can distribute in the common factor of relative address scope, when remaining when distributing the relative address scope to drop to a predetermined value, can require each interface board to report another separately part hardware can distribute the relative address scope once more, and then master control borad can distribute in the common factor of relative address scope at the another separately part hardware that each interface board reports, and before drop to predetermined value the time common factor in, for control information distributes identical hardware table item index in each interface board.Basis like this, the distributed relative address scope of not only having saved each interface board, and, for master control borad, need not once adopt more memory hardware index address because the hardware index address is not too large, also can further save memory source.
In addition, master control borad can increase the control information in its software, and for example control information comprises the situation of ARP list item, can increase by one or some ARP list items, at this moment, can repeat above-mentioned steps.
Can adopt modes such as chained list, array, bitmap to realize increasing the distribution of index in the list item process.For example adopt the mode of chained list, can distribute the common factor of relative address scope according to the hardware separately that each interface board reports, one section during this is occured simultaneously saves as chained list, and when initial this chained list is designated as idle index chain.When master control borad distributes a part of control information, adopt the segment index chain that the linked list head in the idle index chain begins to distribute hardware table item index, and the index chain that will use is designated as and make the index of reference chain.
Master control borad can be deleted the control information in its software, and for example control information comprises the situation of ARP list item, the corresponding control information on can the delete interface plate, promptly corresponding hardware table item.Concrete, can realize the release of index by modes such as chained list, array, bitmaps.Still for example adopt the mode of chained list, when discharging one or several hardware table item indexes, these index moved on in the idle index chain, like this can be when sub-distribution down for using, thereby realized the use of index resource circulation.
