Compared with prior art, since technical solution of the present invention by to hardware in the system identical (or compatibility) mutually but the different different function units of software back up by a stand-by unit, thereby can significantly reduce the quantity of backup units, when reducing cost, can satisfy the requirement of system's reliability service again.
Embodiment
Specify detailed technology content of the present invention below in conjunction with embodiment.
In order to help to understand better the present invention, alleged unit is meant the part of a system among the present invention, and it can be independently parts, a veneer etc. for an equipment, and for a big system, it also can be an equipment.At present industry adopts the significant data in the method standby system unit of N+1 backup usually, but this backup can only carry out in the identical unit of function, for the unit of difference in functionality in the system still carrying out independent backup.
On the other hand, equipment manufacturers are in order to reduce production costs, a lot of functional units in the equipment are adopted identical or compatible mutually hardware designs, realize different business functions by the different functional software of programming device operation, the production and the maintenance cost of hardware development, material procurement and veneer can both be reduced greatly, in a system, just have a lot of hardware identical (or compatible mutually) like this but the different unit of function.And at present general N+1 backup method still needs independent backup at the unit of these difference in functionalitys, can't further effectively reduce cost.
The present invention then provides a kind of new many-one mixing backup method at different function units at this situation, and can utilize a stand-by unit is that identical or the compatible mutually but different a plurality of masters of software of a plurality of hardware back up with the data on the functional unit.
Backup method of the present invention is mainly finished by following several steps:
1, configuration stand-by unit: want to realize that many-one mixes backup, at first to dispose stand-by unit, preserve the required whole softwares of system's all functional units to back up on stand-by unit, normally operate in stand-by state, this moment, control system can be traffic flow configuration to this stand-by unit.
2, fault detect: control system detects each main ruuning situation with functional unit in real time, if detecting certain main break down (comprising software fault and hardware fault) and when having normal stand-by unit, then starts the active and standby flow process of switching with functional unit.
Wherein dual mode is adopted in fault detect usually: a kind of is regularly to inquire about, judge each main working condition with functional unit by system, and another kind is initiatively to report fault by main with functional unit.After system learns that the master is broken down with functional unit, also require current stand-by unit working properly, have only these two conditions all to satisfy just can start and switch flow process.
The user also can be as required, initiates switch flow process by command forces under the normal situation with the unit main, need not consider mainly with unit fault whether in this case, but the normal condition of stand-by unit still need satisfy.
Switching flow process comprises the steps:
(1) stand-by unit function activation: the former fault master of system reset uses the unit, and former fault master is set is stand-by unit with the unit; Notify stand-by unit to activate the functional software of fault master simultaneously, finish necessary initialization, make stand-by unit change new master into and use the unit, have former fault master and use the unit identical functions with the unit correspondence.
(2) masterslave switchover: system start-up masterslave switchover instruction makes stand-by unit can replace the fault master to carry out work with the unit, at this moment system will change corresponding configuration, the feasible Business Stream that was configured to trouble unit originally, all transferring to new master comes with the unit, former like this stand-by unit just becomes the functional unit of main usefulness, can finish former master with the whole function in unit.
3, the former fault master of system reset uses functional unit, and disposing former fault master is stand-by unit with the unit.
More than be that to load leading of all need backing up with standby unit be that example describes with the situation of the software of functional unit.In another technology implementation scheme of the present invention, also can on stand-by unit, preserve the functional software that needs one or several unit in the backup functionality unit, especially under the situation that the functional software in system is bigger, usually select one system very important function software is preloaded in the backup units, purpose is when needs are switched this functional unit, can directly activate this program, save the time of loading procedure, assurance realizes switching processing the most fast to important function, and other functional unit softwares are downloaded by system when masterslave switchover as required temporarily.Other implementation step is identical with embodiment 1.This situation does not just need the whole software of storage on stand-by unit, just just loads required software by system when switching temporarily.
In another embodiment of the present invention, described backup units becomes main with behind the functional unit, not doing stand-by unit after former fault master switches with the unit uses, after as long as former master recovers normally with the unit, system switches back again, former master still is that main to use unit, backup units still be backup units with the unit.
The present invention also can be used for functional unit FPGA (Field Programmable Gate Array) control circuit hardware difference, but only needs just can realize by software change the situation of repertoire of the functional unit of required backup, i.e. the hardware circuit situation of compatibility mutually.The for example main processor that adopts 386 type CPU with functional unit, then can adopt the processor of 486 type CPU to back up them, though 486 different with the hardware of 386 type CPU, but compatible, can finish many-to-one backup requirements equally, corresponding embodiment is identical with previous embodiment.
Another scheme that improves system reliability of the present invention of the present invention is, reserves more than one backup functionality unit in system, for example 10 main with corresponding 2 backup units of functional unit, or 10 main with corresponding 3 backup units of functional unit etc.
In addition, need to prove that the software of indication of the present invention can also be encode or the symbolism command sequence that programmable logic, microcode or the like can online change functions.The just structures that adopt CPU+NP of for example at present high-end router applications are finished different functions by loading different microcodes more, and the present invention is equally applicable to this situation.
In summary it can be seen, the present invention is identical or the compatible but different functional unit of software mutually for hardware, back up by at least one stand-by unit, can greatly reduce the quantity of backup units, reduce the system hardware cost, can satisfy again simultaneously the requirement of system's reliability service, have significant technique effect.
