Detailed description of the invention
The embodiment of the present invention provides a kind of synchronous method of data and device, main in order to configure between peripheral nodeStandby, synchronization node resource data.
In the embodiment of the present invention, the configuration of peripheral node adopts N+M backup design, and has adopted x group n+mThe model of backup group, is divided into multiple little backup groups, N, M, n, m, x by N+M backup groupIt is all integer. N primary peripheral node is divided into x and organizes primary peripheral node group, each group of interior primary peripheryNumber of nodes is n, and the quantity of every group of n can be different, and corresponding M peripheral node for subsequent use is also divided into x with itIndividual peripheral node group for subsequent use, every group of interior peripheral node quantity for subsequent use is m, the quantity of every group of m can be different.For the primary peripheral node and the peripheral node for subsequent use that have in a backup group of standby usage relation, need to realizeIn group, the data of n primary peripheral node back up on m peripheral node for subsequent use, for same group simultaneouslyThe Backup Data of storing on interior peripheral node for subsequent use is consistent. If certain primary peripheral node fault or he sends outStranger is when switching, and the peripheral node for subsequent use in is on the same group preferred secondary node, preferentially corresponding for replacingPrimary peripheral node. And when all peripheral nodes for subsequent use in this N+M group are all when fault, select less preferred groupIn peripheral node for subsequent use replace this primary peripheral node. Backup relationship model figure as shown in Figure 1.
For N+M backup functionality, the present invention has designed N+M standby usage relation table, wherein deposits N+M standbyThe node of part switches and node standby usage relation, and N is primary peripheral node number, and M is peripheral node number for subsequent use,The each peripheral node of N+M all represents with logical address (virtual address). Primary peripheral node number be necessarily greater than orEqual peripheral node number for subsequent use. Do not allow to occur that certain peripheral node for subsequent use does not belong to any primary peripheral nodeThe configuration of preferred secondary node, that is: peripheral node for subsequent use must be the joint preferred for subsequent use of a backup groupPoint occurs; The preferred secondary node list collection that in same backup group, primary peripheral node is corresponding should equate.In addition, according to backup relationship model, whole peripheral nodes are divided into multiple for subsequent use group by standby usage relation table,Between peripheral node in each for subsequent use group, there is standby usage relation.
The node main and standby relation of N+M type is carried out ruling by Centroid, when system initialization, at centerOn node, need to build the physical address of N+M type peripheral node and the correspondence table of logical address. And,When initialization, the structure of this correspondence table relies on static configuration relation and determines. Centroid is received N+M typeAfter message with don't-know state registration after peripheral node starts, the configuration of inquiry standby usage relation table and corresponding table,Determine the active and standby type of this peripheral node, if primary peripheral node returns and succeeds in registration, and to indicate be mainWith state; If peripheral node for subsequent use and can register time obtains master corresponding to current peripheral node for subsequent useBy the information of peripheral node, notifying this peripheral node is stand-by state, and indicates the master that this peripheral node is correspondingBy the information of peripheral node.
It is synchronous that N+M backup need to be carried out data, the synchronous guarantee standby system of each node data normalOperation.
Referring to Fig. 2, a kind of synchronous method of data that the embodiment of the present invention provides comprises:
The standby usage status information that S201, peripheral node receiving center node send; Wherein, described standby usageState be Centroid according to comprise primary peripheral node virtual address and peripheral node virtual address for subsequent use itBetween the standby usage relation table of corresponding relation, and the physics of current each virtual address and each peripheral nodeMapping relations between address are determined;

In the embodiment of the present invention, peripheral node includes but not limited to server, the forms such as industrial computer, veneerNeed the equipment of the core network of backup; Peripheral node can be both equipment independently, as server; Also can beVeneer, each veneer centralized configuration is on backboard. Taking the peripheral node of veneer form as example, provide this belowBright specific embodiment.
Specific embodiment 1: see table 1, the backup relation table providing for specific embodiments of the invention.
In backup relation table, ucModule, usGroup, ucSGroup represent primary in N+M backup groupVeneer is the logical address of mainboard, ausBakGroup1List/aucBakSGroup1List,ausBakGroup2List/aucBakSGroup2List、ausBakGroup3List/aucBakSGroup3ListRepresent that respectively the standby board in N+M backup group is the logical address list of slave board, wherein,AusBakGroup1List/aucBakSGroup1List is preferred backup group list. If in current backup groupMain board failure, the slave board in preferred backup group is replaced and is risen master. If the veneer in current preferred backup group allFault, selects normal slave board in backup list 2 and backup list 3 to replace liter master successively.
Table 1
Specific embodiment 2: in communication equipment, the data in each peripheral single board need to Centroid onData are consistent, and also will keep data consistent between active and standby peripheral single board. In order to ensure data on each veneerValidity and uniformity, need to synchronously ensure by the data of database subsystem, wherein, databaseThe structural design of subsystem is distributed processing mode, and database relation collection is distributed on each modal processor.Synchronously specifically comprising of database subsystem: the synchronous and dynamic data synchronization of static data.
Static data is the configuration data being sent by Centroid, in the time that peripheral single board initialization powers on, needsThe data of synchronous Centroid are to each peripheral single board. Static data in peripheral primary Board Power up process is synchronousProcess is as follows: in the time that peripheral single board initialization powers on, the static data synchronization module on peripheral primary veneer is receivedThe thread activation request message sending to Centroid, then initiates static data taking Centroid as synchronisation sourceSynchronizing process, completes whole table synchronous.
Referring to Fig. 4, the static data synchronizing process in peripheral standby board power up is as follows:
S401, peripheral standby board are received after thread activation request message, send out message to data on CentroidThe active and standby synchronized transmission thread of storehouse subsystem obtains partner's plate information of this slave board, and obtains in backup groupThe address of all primary single board list, standby board list, current slave board corresponding mainboard in backup group etc.
Due in N+M backup group, mainboard is counted N and is more than or equal to slave board and counts M. Therefore no matter be N==MOr N > M, in slave board list M the subscript of each slave board can be in mainboard list N unique correspondence that findsThe subscript of mainboard; Find mainboard corresponding to subscript to find the ground of current slave board corresponding mainboard in backup groupLocation.
S402, standby board be using this primary veneer as synchronisation source, and initiate active and standby synchronization request message to it,Carry out master/slave data synchronous, as shown in Figure 5.
In like manner, if in system running, revise after configuration data by webmaster, primary veneer with inIt is synchronous that heart node is that synchronisation source carries out static data successively; After primary veneer synchronous completes, can be at N+M(querying method is also by looking in backup relation table, to inquire about the current standby board address that this primary veneer is correspondingAsk target slave board ground under standby list corresponding to subscript in the primary list of current mainboard place N+M backup groupLocation), and send active and standby static data synchronization message, specifically see schematic diagram 6.
Synchronously realizing by means of dynamic data synchronization between peripheral single board of the dynamic data of N+M backup,When mainboard is synchronous to slave board, be not to be just synchronized to a slave board, but each mainboard need to sameAll slave board synchrodatas in group, because the dynamic data of each mainboard distributes, possibility is inconsistent, but slave boardOn dynamic data be on the same group in the complete or collected works of dynamic data of all mainboards; Mainboard is to slave board synchrodataTime, need to know the static data synchronous regime of interior all slave boards on the same group, therefore, need to back up at N+MThe static data synchronous regime list of all slave boards in safeguarding on the same group on each mainboard in group, this list is by quietState synchronization module is safeguarded, and is provided the static data of certain slave board of inquiry synchronous to dynamic data synchronization moduleThe function of state. Fig. 7 is the schematic diagram of active and standby dynamic data synchronization. Referring to Fig. 8, dynamic data synchronization mistakeJourney is as follows:
In S801, backup group, mainboard is safeguarded the synchronous regime of slave board, on the same group in the static data of all slave boardsSynchronous regime; Specifically comprise the processing of following situation:
Mainboard is received powering on when Indication message of slave board, and it is in synchronizing process that slave board synchronous regime is set;
After mainboard receives that the whole table of slave board responds with EOS, the synchronous regime that slave board is set is synchronous normal knotBundle;
When in active and standby plate synchronizing process, because slave board problem causes, after active and standby synchronization failure, the same of slave board being setStep state is synchronous for not carrying out; When because mainboard problem causes active and standby synchronization failure, slave board can be to allIt is synchronous for not carrying out that mainboard is sent out its synchronous regime of information updating;
In the time that mainboard receives that the slave board state variation Indication message of system management and the state of slave board are fault,Slave board synchronous regime is set synchronous for not carrying out;
In the time that mainboard receives that the standby liter of system management has been led Indication message, first slave board synchronous regime is set toNot synchronous, then send out request message and obtain the synchronous regime of slave board to the receiving thread of standby board.
S802, determine dynamic data synchronization mode according to slave board synchronous regime;
If it is synchronous that slave board is carrying out static data, buffer memory sends synchronization request message; If slave boardSynchronous regime is synchronous normal termination, sends immediately synchronization request message. Specific as follows:
If object veneer is in static synchronous process, start timer and wait for that static synchronous process finishes,After finishing, static synchronous sends again synchronization message synchronous dynamic data. If timer expiry static synchronous does not also haveHave, in max-timeout sending times, reset timer, waited for always. If expired timesReach max-timeout sending times, think and abandon message misprint by synchronization failure, then send out to webmasterSend alert message. This situation only just may occur in the time that Board Power up initializes.
Otherwise, send at once synchronization request message.
Consider that veneer is fed back to malfunction to other node, therefore fault shape during the initialization startingState need to be carried out following specified otherwise:
Object veneer is malfunction and not in static data synchronizing process, is divided into two kinds of situations: a)Real down state, all message that sends to this veneer is all dropped; B) static synchronous completes,But now activating other threads, so the transient state in single board default now can send same at onceStep request message.
Specific embodiment 3: configured the logical address of mainboard and slave board in backup relation table, this logical addressBe virtual, only have the physical address that logical address is mapped to peripheral single board, could be by backup relation tableThe relation of veneer correspond in real veneer; When system initialization, these mapping relations are entered by CentroidRow configuration. Backup relation table and mapping relations can send to whole peripheral nodes.
When active and standby switching has occurred the peripheral single board of N+M configuration in running, need to be by active and standby switchingThe logical address of veneer and the mapping relations of physical address exchange, switching principle is: rise main physicsVeneer uses and is configured to primary logical address, falls standby Physical board use and is configured to logically for subsequent useLocation, thus ensure after active and standby switching normal according to new logical address communication between system. Veneer is according to exchangeAfter mapping relations determine the main and standby relation between this plate and other plate.
Referring to Fig. 9, taking 2+1 backup relation as example, mainboard A1 and slave board B1 are switching front and back, each veneerLogical address between relation do not change, be only to have changed physical address corresponding to logical address.
When the mainboard in N+M backup group is received having led after Indication message for rising of system management, if sentencedDisconnected current single board is N+M type of backup, needs to inquire about backup relation table, thereby obtains current mainboard pairThe slave board list of answering, and send a request message and obtain the synchronous shape of slave board to all normal slave board gettingState, upgrades the list of slave board synchronous regime; Thereby for dynamic data synchronization provides corresponding query interface. Be S801In: " the standby liter of receiving system management when mainboard led after Indication message, first slave board synchronous regime arrangedFor not synchronous, then send out request message and obtain the synchronous regime of slave board to the receiving thread of standby board.
