Description
Technical field
The present invention relates to cloud computing technology field, specifically the elongated sequence number algorithm of higher, the distributed modular system that maintains easily of a kind of efficiency.
Background technology
Distributed system (distributed system) is the software systems that are based upon on network.Exactly because the characteristic of software, so distributed system has cohesion and the transparency of height.Therefore, the difference between network and distributed system is more high layer software (particularly operating system), instead of hardware.Cohesion refers to each database distribution node high degree of autonomy, has local data base management system (DBMS).The transparency refers to that each database distribution node is transparent concerning user's application, does not see local or long-range.In distributed data base system, the imperceptible data of user distribute, and user not must know whether relation is cut apart, has or not copy, data to be stored in which website and affairs are carried out etc. on which website.
Computing technique develops towards modularization and service-oriented future development, and the development of the modularization standard taking REST as representative and perfect, makes computing technique more trend towards distributed and parallel computation.In such system, in order to protect the business rights and interests of development company, the elongated algorithm of sequence number, surely escorting for this type of software.
Conventionally the information that is comprising modules in the sequence number structure of distributed system, they divide segment record.In systems development process, if because exploitation needs or demand change, the number of module is increased, if what now adopt is the sequence number generating mode of fixed length location, surely can increase complexity and the difficulty of system, bring very large inside hidden danger to the maintenance in later stage simultaneously, even occur, the sequence number in early stage, after later stage upgrade-system, the risk that can not re-use.
Based on this, a kind of elongated sequence number algorithm of distributed modular system is now provided, by elongated the content segmentation of each module leaving in sequence number plain code, crack elongated algorithm simply efficient, improve superiority and the ease for use of later maintenance.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and a kind of elongated sequence number algorithm that has the distributed modular system that complexity is lower is provided.
Technical scheme of the present invention realizes in the following manner, the elongated sequence number algorithm of this kind of distributed modular system, and its implementation procedure is:
One, collect the information of modules, and for each module rise one independently module number;
Two, the parsing of each inside modules is carried out according to position analytical method;
Three, automatically generate new module, form elongated sequence number expressly, by the product form of cryptographic algorithm formation sequence number;
Four, when system starts, from database, read sequence number information, crack sequence number information, and information is positioned in the internal memory of public module, realize the effective of module information is read and for logical operation.
Further, the module in described step 1 is numbered A～Z; The structure of the sequence number in step 3 is: beginning and end is all 3 random digits, and centre is the numbering of 25 modules of A-Z.
In described step 3, system automatically generates the process of new module and is:
In the time that module increases, system generates new module automatically, and relevant information according to the structure of new module sequence number, after adding original module data to.
The detailed process of described step 3 is:
A～Z is mapped in map data structure, corresponding with module title;
After the deciphering of reversible encryption pattern, remove the random number at character string two ends;
Press index function index size, since 0, when charindex function is greater than 65 and be less than or equal to 90, module is started to sequence number and is arranged to the currency of index; If index is not 0, intercepting this segment data that current index starts sequence number to module is the data of a upper module.
The detailed process of described step 4 is:
After system starts, public module obtains the information in database, after cracking, joins in the data structure of valueMap and stores;
Multiple interfaces that obtain content in data of dishing out, call for service layer;
By the mapping table of module name and A～zee, realize the effective of module information is read and for logical operation.
The present invention is different from traditional sequence number algorithm, this method is that the elongated analytical algorithm of sequence number is basis, the information of distributed modular is stored as prerequisite, the mode of resolving by staging treating sub-module, flexible and efficient module information being stored in sequence-number field or resolve extracts, module information after resolving is placed in the internal memory of shared module simultaneously, with the access of aspect modules, raises the efficiency.
The beneficial effect that the present invention compared with prior art produced is:
The elongated sequence number algorithm of a kind of distributed modular system of the present invention can reach when in the situation that module increases, do not change the program of formation sequence number, only need change into ginseng, the just energy effect of sub-module control relevant information flexibly, reduce modular complexity and the degree of coupling, optimization system framework is saved development of manpower cost and later maintenance cost simultaneously; Applied widely, except being applied to the sequence number algorithm field developing software of cloud computing distributed modular, also can be applicable to in non-cloud computing in other higher software application of modular requirement; This method, by elongated the content segmentation of each module leaving in sequence number plain code, cracks elongated algorithm simply efficient, and later maintenance and ease for use are superior, practical, is easy to promote.
Embodiment
Below in conjunction with example, the elongated sequence number algorithm of a kind of distributed modular system of the present invention is described in detail below.
In order to reach when in the situation that module increases, do not change the program of formation sequence number, only need change into ginseng, the just energy effect of sub-module control relevant information flexibly, reduce modular complexity and the degree of coupling, optimization system framework, the invention provides a kind of elongated sequence number algorithm of distributed modular system, following 2 points of design basic thought of this algorithm.
One, calculate by the algorithm that module arbitrarily increases and module contents arbitrarily increases, make the distributed system can be under the condition of maximum independence, reduce the coupling of module on sequence number, increase system ease for use.
Two, sequence number decrypting process only carries out once in the time that system starts, and operation result is positioned in the internal memory of public module, improves the efficiency of acquisition of information in sequence number.
