Financial payment field, internet, EPC traffic payment system:

EPC(Electronic Picture-catching Collecting) namely pay capturing system by mails.Refer to that vehicle is when by charge station, realize vehicle identification by vehicle identification system, information writes (entrance) and automatically pays from the Hart bound in advance and spatially deducts corresponding fund (outlet), is a kind of E-payment system managed for road, bridge, tunnel and parking lot based on HIEP agreement.

Paying capturing system (EPC) by mails is state-of-the-art Fare Collection System in the world, it is one of service function of intelligent transportation system, vehicular traffic need not stop by during the road junctions such as highway, bridge, tunnel, namely can realize that testing vehicle register identifies automatically, automatic fee.In the management of parking lot, for improving gateway vehicle pass-through efficiency, build unattended express passway, the discrepancy experience of exempt from card taking, not stopping, is just changing the management mode in parking lot of coming in and going out.

In conjunction with in HIEP, http communication agreement, by WEB service, realize the technology that vehicle electric pays.

Based on HIEP(HTB Internet E-wallet Protocol) Hart pays the EPC(Electronic Picture-catching Collecting in space) Design and implementation.

Hart pays space and is applied to HTML(data outward appearance display internet standard protocol), it has a set of rule of conduct had about interface, comprise global naming and quote, register, communicate, information processing, life cycle etc.; In the entire system, we have employed the mode of B/S framework WEB remote monitoring, by the characteristic of the cross-platform of JAVA language and network programming thereof, with the long-range control method of JNI and SOCKET programming, the Long-distance Control using the method for programming to realize the monitor node in wide area network, enables the monitoring that main frame realizes remote equipment.Design and develop the process based on three-decker distributed system; And be background with compressor long-distance monitoring system, use the technology such as DCOM, ActiveX and remote scripting, realize an EPC concrete utilization.

The realization of 1.WEB Long-distance Control

1.1 Long-distance Control machines (bank preposing transaction system) and on-site monitoring equipment is interconnected

On existing LAN basis, the interacted system of formation as shown in Figure 1, realizes Long-distance Control, then by a Monitor and Control System based on arrowband multiple protocol environment.Bandwidth is adapted to by frame per second self-adjusting, and the exchanges data relying on protocol gateway to carry out between IPX and TCP/IP, realize remote monitoring.

SHAPE * MERGEFORMAT SSClient first create a client Socket object, be connected with the service routine operating in host port 10000, attention port should be greater than 1024, in order to avoid clash with the port numbers of system; The IP address of main frame has host variable to determine, carries out read-write operation around the inlet flow of BufferedReader and the output stream of PrintWriter to character string, for server being passed the order and parameter of coming and other programs are carried out alternately.Exception catching is carried out with try catch statement in whole program segment.

The program composition of server end should adapt with the establishment of client-side program.Because a Long-distance Control machine can control multiple on-site monitoring equipment, so server program must adopt multi-thread mechanism, this is also a large characteristic of Java language.

This program segment is made up of two classes: main classes and thread class.Main classes is responsible for setting up server socket ServerSocket, and port numbers must be consistent with the port numbers of client computer, then creates a sockets interface by the accept method of ServerSocket, the communication of special disposal and client computer; Thread class, for creating a new thread, is responsible for the input and output request of each on-site monitoring equipment of process.Certainly each client also can adopt different port numbers to send request to server, and the client that server also creates the thread of different port number consistent with port numbers accordingly communicates.

Long-range control host machine server program must have the ability of carrying out dynamic interaction with database.Deposit a large amount of field datas in database and control the parameter of execute-in-place and order etc.A certain thread body in server program is responsible for the operations such as access to database, amendment and maintenance, and Java language realizes the connection with database by JDBC; Make Java language can by driver accessing database.

1.2 JNI specific implementations

Java language can only adopt third party's language to carry out to the control of monitor node, such as C or assembly language.Because the communications portion Java language of controller is write, for realizing the control to monitor node, the JNI technology of Java language just can realize with C and C Plus Plus flawless combine, although this sacrifices transplantability to a certain extent, but enable Java language and concrete environment come into contacts with, possess the ability driving hardware.In the example that native system realizes, the application of EPC and driver C language is developed, and Java language makes nation method body the program that C language is worked out.Thus realize the control of native system.

Write the driver C language of monitor node, the C built-in function of the function major part Shi Yanhua company exploitation adopted in program, utilizes these built-in functions to drive watch-dog to complete various function.These procedure sets are become Java nation method body, becomes the gordian technique realizing Long-distance Control with Java language.

For controller, utilize the integrated nation method of Java.

This section of program is made up of main classes and nation method class, and main classes, also must instantiation nation method class except the program completing communications portion, and calls nation method; When defining nation method class, keyword native must be added, and there is one section of static code in program segment, this static code is that nation method class loads drive storehouse by system function, go to obtain the data in monitor node or data acquisition unit by the execution of nation method again, pass to data server.

So far, the code of remote monitoring equipment just achieves substantially, it mainly comprises the Socket service device and nation method application that operate in controller one end, have " RUN " order that server monitoring is sent from far-end (Browser), Socket service device calls according to " RUN " order transmitted again and is operated accordingly by the EXE programmed control of nation method or runtime server end.In data acquisition application, JNI method is adopted directly to be inserted into background data base reading the data gathered, then JDBC accessing database is adopted to be presented at Browse end, because system must first drive reading data, adopt multi-threaded approach to realize time delay, guarantee after data have been transmitted in the display of Browse end.For other embedded system such as supervisory system, the communication mechanism of the integrated of nation method and Socket network can be adopted equally, effectively controller and distance host are coupled together by network, to realize Long-distance Control.

Send different command road servo driver end by bottom Socket communication mechanism and carry out corresponding process.Due to the platform-neutral of Java language, make Java with nation method integrated in conceal a large amount of ins and outs.

2. the design of system

2.1 for EPC front platform industry long distance control system, the structural design of system as shown in Figure 2 SHAPE * MERGEFORMAT

Due to history, watch-dog can not directly and information network carry out communication, so in the design process of system, between middle layer and watch-dog layer, add industry control station, as the data service layer of three-decker.

Such project organization can make the exploitation of middle layer and presentation layer be totally independent of particular type and the structure of industry control network, and industry control stands in the effect serving intelligent gateway in the connection of industry control network and information network, shields industrial control network.Thus, the various advantages of three layers of C/S structure in Internet/Intranet application can be played completely.

The gordian technique that 2.2 systems realize

According to above design architecture, take compressor long-distance monitoring system as example, this system realizes distributed three layer structure with B/S structure, and has used the technology such as ASP, DCOM, ActiveX technology and remote scripting of Microsoft.

2.3 based on arrowband multi-protocols EPC supervisory system implementation model

System can adopt bandwidth only to have 64Kbps, and also needs on this channel to run a small amount of data-transfer applications, and thus effective bandwidth is very limited.The requirement of user to single-frame images is higher, and in order to carry out dynamic frame per second and two field picture adjustment better, we have employed the Motion-JPEG form of customization.In addition, user is in order to the safety of network, and adopt agreement to separate mode, leading portion operates in an Internetwork Packet Exchange LAN, and far-end is then the Intranet based on TCP/IP, and the data transmitted need to change between IPX and TCP/IP.Like this, also must construction protocol gateway between front-end collection and remote monitoring.This system physical structure can be divided into 5 parts: 1) head end video equipment; 2) front-end control PC; 3) communication line; 4) protocol gateway; 5) remote controller.Whole system contains the modules such as collection, compression, preservation, network transmission, remote monitoring, structure as shown in Figure 3:

Because the message sink coding of this model, decoding, transmission, playback and storage are all based on software simulating, the parameter such as frame per second and picture reconnaissance all allows user's dynamic conditioning, and realize certain bandwidth self-adaption by systems response, so basic QoS can be ensured.

2.4 Location of Vehicle License Plate algorithms

Native system carries out topography for common CCD camera candid photograph image and strengthens process, and obtain desirable vehicle license plate characteristic and describe, efficient in conjunction with genetic algorithm, feature meets the regional location of vehicle license plate characteristic most at full figure range searching fast, thus accurate positioning licence plate.1) Image semantic classification; 2) topography's process; 3) feature statement.

(2) design of charge system

The function of 1.EPC charge system:

In this projector operating and managing, the webmaster personnel of bank preposition system (BFS) to be calculated whole EPC by EPC management of computing system and manage, and comprise the current operating state of all equipment or facility in all EPC computing systems and running parameter, the duty of equipment or facility are controlled to (as started, closing), operation of modifying etc. to running parameter.The user job that EPC computing system is submitted to calculate EPC user, need between EPC user and local user, contact is set up between EPC resource and local resource, EPC user is namely needed to be mapped as local user, be local resource by EPC resource mapping, the use of EPC user to EPC resource is mapped as the use of local user to local resource.(list of references 7 " The grid:Blueprint for a New Computing Infrastructure ").Abstract EPC calculates and is converted into concrete local computing by this series of mapping process, EPC system, by performing concrete local computing to complete abstract cloud computing, carries out concrete operation by specific transmission line and control protocol to the long-range network equipment or facility.

2.EPC charge system structure is for shown in Fig. 4:

2.1 authentication modules:

To the proof module of entity identities in computing machine EPC system.Entity comprises resource or user, realize its certification by HIEP authentification of message certificate, HIEP authentification of message is signed and issued by mechanism trusty, shows as a segment information, this segment information includes the information of certificate owner, the effective time of certificate and the digital signature of authentication module.To user or the resource of all access, its information is recorded in accounting module.

2.2 user agent module:

When user needs to use EPC resource to carry out EPC calculating time, user's initial landing one is connected to the computing machine of HIEP bank preposition system, and connect user agent module, then user by need application resource information and calculative user job for he give user agent, user agent module replace user complete two-way authentication, application resource, submit job, obtain the work such as result.

2.3 resource proxy modules:

When one group of resource adds EPC computing system, first Resource Manager wants connection resource proxy module, and this Resource Broker is responsible for the work of this group two-way authentication of resource, distribution and recovery.Resource Broker not necessarily operates on the node of this group belonging to resource, but this group resource of Resource Broker and its management will in same local trust territory.

2.4 resource distribution modules:

A process created by EPC computing system, is responsible for the management work of resource, conveniently manages a large amount of dynamic resource, simplifies complicated resource allocation process simultaneously.Resource distribution module sends resource requirement information to Resource Broker.The information that it manages by all Resource Brokers issues resource distribution module, and when resource updates, the lastest imformation of resource is sent to resource distribution module.This module arranges the resource information received, and forms resource information that is abstract, logic.Therefore, resource distribution module is the core of information interchange between a module.

2.5 accounting modules:

The information of this module record set process user and resource, authentication module joins the user of this EPC computing system and the information write accounting module of resource all applications, resource distribution module also writes this module the information of submit job after user completes calculating, carries out record by this module to it.

The realization of 3.EPC charge system

The flow process of 3.1 chargings

3.1.1EPC computing system manages resource, and distributes resource according to the situation of user, and each entity obtains the process of entity certificate;

3.1.2 user creates the process that user agent and user agent submit user job to;

3.1.3 the calculation process of user job;

3.1.4 the dispose procedure of resource.

3.2 EPC calculate the design and implimentation of database:

If we will manage a small-scale EPC, in accounting module database, recording user information, resource information, user use the information of resource.It is convenient and swift that we not only will ensure that data store, more to ensure consistance and the integrality of data, whole charge system is made up of multiple thread, they exchange information by a shared drive, because multiple process will access shared memory field simultaneously, the conflict of share and access will be produced.

The conventional method solving share and access conflict adopts locking mechanisms to solve, but very Iarge-scale system resource is inherently taken to the locking and de-locking of shared drive, thus the performance of EPC system can be affected, therefore we are by the read-write region of each process in reasonable arrangement system, avoid two processes to revise an internal storage location simultaneously, just can prevent sharing conflict and not need to carry out locking and de-locking operation.Data layout in our design database is as shown in following table 1-3:

				htbuser_id	String	16	User ID, using the code name of EPC user, is one of candidate key
htbres_id	String	16	Resource code name, the code name of resource in this process is one of candidate key
				flux	Long	32	Flow when user uses resource to calculate
start_time	Timestamp	8	User brings into use the moment of resource
				end_time	Timestamp	8	User terminates the moment using resource
time	Time	8	Current state is validated user or disabled user

For avoiding internal memory sharing conflict, each table between relation as shown in Figure 5:

In order to prevent share and access conflict, we arrange different processes to write different regions, and wherein, htbuser_id, user_type are only write by user agent's process; Htbres_id, res_type, in_time, out_time are only write by Resource Broker process; Usercer_id, state, rescer_id are only write by authentication processes; Flux, start_time, end_time are only write by Resourse Distribute process.These regions only can perform write operation in a process, and other processes are read-only, so there will not be sharing conflict, ensure that the security of database to a certain extent.

(3) fee evasion capturing system

The first situation:

Vehicle is legal identity, uses normal payment

The second situation:

Vehicle is legal identity, but can not normally pay the fees (comprise and resist payment), be then recorded to blacklist server CRLs;

The third situation:

Vehicle is illegal identity, is forced through EPC passage, will be recorded to blacklist server CRLs;

In this project, fee evasion capturing system is that client behavior record after occurring in two kinds of situations is to blacklist server.When generation the second situation is that the settling bank being paid address by this Hart carries out deducting fees or punishing automatically; When there is the third situation, this information of vehicles is transferred traffic process.

In this project implementation, according to XHSI (X.509V3 privately owned extension HIEP authentification of message system), for the underlying security service of the HIEP that provides support.X.509 digital certificate is used to provide certification and message protection in HIEP extension.What adopt the second situation is the mode of certificate revocation list CRL.

What adopt here is combine based on XHSI one-way hash chain, HIEP extension and CRLs shared model the scheme of cancelling, its advantage is: the participation not needing CA during certificate revocation, the problem of single point failure and CA cross-certification can be solved preferably, traffic congestion and the real-time guaranteeing certificate revocation can be avoided.

Scheme cancelled by 1.HIEP extension participating certificate:

The situation of certificate revocation has two classes: the first kind is that the private key corresponding with PKI is lost or reveal; Equations of The Second Kind is that certificate contract may stop, or the identity of the holder described in certificate changes or business information is cancelled.The one-way hash chain that this programme uses, for above-mentioned first kind situation, can not need the participation of CA and make certificate temporarily or permanent failure.For Equations of The Second Kind situation, HIEP extension and CRLs shared model can be used to realize illegal charging.

2. based on the New Certificate of one-way hash chain

Hash chain is based on a disclosed function H, and this function is easy to carry out forward calculating but may carries out backwards calculation hardly under existing computing environment.If the input of one-way function is fixed length, one-way Hash function that Here it is (OWHF).

We are divided into multiple segment the maximum vital values of a certificate.Certificate can be expired at the end of any one time period, expiredly can be controlled by the owner of certificate or its supvr.Certification authentication person need not obtain the validity of revocation information with regard to energy authentication certificate from CA.Therefore, this revocation mechanism simply safety.One-way hash chain carries out recursion to set up to an one-way Hash function by inputting a character string, Hi (r)=H (Hi-1 (r)) (i=1 can be expressed as, 2 ...), H0 (r) here=r is hash chain root.

Certificate update time point is defined as: D1=D+L, D2=D+2*L ... Dj=D+j*L, and produce one-way hash chain Hi (r)=H (Hi-1 (r)) (i=1,2, j), H0 (r)=r and r is a random number being only known to user U.End user sends request (PK1, D, Hj (r), j, L) to CA.

The request of ca authentication user Generate Certificate (PK1, D, Hj (r), j, L).Compared with traditional public key certificate, certificate CERTu comprises extra data (Hj (r), j, L).As shown in Figure 6, user can discharge the validity that Hj-1 (r) carrys out initialization certificate after CA acceptance certificate.

If user is because certain reason needs cancellation of doucment, release cryptographic hash can be stopped to make certificate expired at next renewal point.User even can make certificate temporarily lose efficacy, and then again discharges corresponding cryptographic hash when needed and carrys out more new authentication.

The multiple certificate of 3.HIEP describes

In order to solve the problem of single point failure and CA cross-certification, we have proposed the new certificate mechanism that is called multiple certificate.We form a virtual tissue (VO) several CA.When a CA issues certificate, other members in this Virtual Organization according to a predetermined sequence to the content signature of certificate, and produce the auxiliary certificate that comprises original certificate content and CA self signature separately.Such as, as shown above, user sends its certificate request road CA.If this request of ca authentication, will issue a certificate.Meanwhile, auxiliary CA1 also will produce auxiliary certificate 1 to this certificate signature, and then auxiliary CA2 signs to auxiliary certificate 1 and produces auxiliary certificate 2, the like.Therefore, only need to obtain the validity that any one auxiliary certificate just can verify a certificate, and do not need directly with issue this certificate CA and directly communicate.

4.CRLs shared model

User and the resource of enormous amount is had in EPC application.Each user and resource hold a certificate.When their certificate needs to cancel, huge CRLs can be brought to CA.The server of CA will become the bottleneck of whole system, and network delay increases, and user cannot obtain certificate revocation information in time.In addition, because EPC node is dynamic, even if must guarantee that all nodes also can reliably obtain up-to-date CRLs in the temporary transient disabled situation of listserv.According to this characteristic of EPC, this project proposes CRLs shared model.

Each EPC node downloads CRLs from the LIST SERVER of CA, then issues with the form of EPC service.EPC node according to according to CA after first other nodes rule searching and obtain CRLs.The CA private key of oneself is signed to CRLs, to guarantee that CRLs is not tampered.

5. conclusion

For the first vehicle condition, the New Certificate of one-way hash chain can be used realize.

For second and the third vehicle condition, the multiple certificate of HIEP can be used to realize.

Whole scheme is realized by CRLs shared model.

Advantage based on the program:

5.1 certificate revocations are independently real-time

Because certificate is issued based on one-way hash chain, user can make certificate temporarily or permanent failure with stopping the method for release cryptographic hash.This will come better independence and security to user's use certificate book band.Also mitigate the burden of CA in communication and process simultaneously, the real-time cancelled can be improved.Add and have employed CRL shared model, EPC Computation distribution, dynamic feature can be adapted to better, ensure that all nodes can obtain up-to-date revocation information in time.

5.2 certificate managements are simple and reliable

Owing to have employed HIEP multiple certificate authority mechanism, the certificate that different CA issues can carry out mutual certification, and user directly access certificate issue the validity that CA just can verify this certificate, avoid the single point failure of EPC system.

(4) EPC bank preposition system BFS

1 based on the realization of the distributed BFS parallel calculating method of Scilab.

Based on Schab [3] computation engine, with OpenBFS/webBFS for background, under relating to BFS environment, Distributed Parallel Computing instrument (Netbutterfly htbBFS Computing System NBFS) is to support that BFS carries out the implementation platform of extensive scientific algorithm.

The distributed parallel computing structure of 1.1NBFS

As shown in Figure 7:

The BFS computer node of being served by multiple BFS of providing forms a virtual parallel machine.It can complete the parallel computation task submitted to by BFS client.A node of each BFS computing node and parallel computation, provide one or some can the parallel BFS service of the task such as executed in parallel.As the complete package to calculation resources, BFS computing node has been used for concrete calculation task, and he uses Scilab as algorithm description language.The difficulty that user describes scientific algorithm problem can be reduced.Computing power that calculation services layer (virtual parallel machine) is abstract, when calculation task is accepted, it will come by the suitable computational resource of Automatic-searching.Application layer is mainly used for effectively using calculation services and managing, and processes the problems such as many application coordination.Pay space by WEBHTB(Hart) the parallel OPENHTB(Hart that calls pays space) Service Instance.

1.2NBFS designs framework

1.2.1NBFS application structure mode

As shown in Figure 8:

Data capsule mainly leaves concurrent program and application data in.Computing container comprises N number of resource node, for system provides computing power, Resource TOC service comprises calculation resources service and data resource service, when NBFS runs, node sends to data capsule editting of task, data capsule and computing container find resource requirement by directory service, until computing completes.

1.2.2 server system design

NBFS have employed Core server group structure at unable realization row.Client is resource provider and resource transfer person, and intrasystem computational resource comes from effective gathering of client resource.The server of NBFS adopts the clustering design of expansion, and modules can run respectively.Server group structure as shown in Figure 9.

1.2.3 client node design

The client node of NBFS comprises task access interface and ScilabBFS calculates virtual machine.Task access interface is the interface that user applies for entering NBFS, user by task access interface job invocation to NHCS system, ScilabBFS calculating virtual machine is the operation node of NBFS, and it provides arithmetic capability for system.Client node divides mission mode and computation schema.The former submits calculation task wait for complete process to system for node, and the latter provides calculation services to system for node.So, it supports any machine from microcomputer to giant computer, from Windows to Unix and Linus and any operating system that may occur in the future, greatly facilitate the network parallel between Heterogeneous Computers, thus existing Internet resources can be utilized fully to carry out distributed parallel computing.

1.2.4 system coding design

Native system have employed Scilab language as scientific algorithm script descriptive language.Scilab sets up automation research institute (INRIA) by France and EBFS develops " open source code " software, use Scilab to be conducive to the quick description of calculation task as application scenarios language and user grasps fast, thus improve the description efficiency of user to scientific algorithm problem.Application program due to NBFS have employed the mode being interpreted as performing, and the application scenarios of NBFS directly can be run at the NBFS node of different platform, and in different operating system node, a common operation concurrent program, has good isomery extended attribute.

In order to the parallel computation making Scilab be applicable to networking, system adds teledata read write command NBFS-RD and NBFS-WS, eliminate the dangerous command that disk operating etc. may endanger client computer, whole computing the entrance of program is Mainnhcs file, other programs are called as process.Mainnhcs is a file describing task flow.Grammatically only have both keyword NBFS-CX and NBFS-END.

NBFS-CX: the condition of program performs, when expression formula X is true time, system in parallel performs all functions in NBFS-CX statement.

NBFS-END computing terminates, and this instruction is generally used for ends with system task, and discharge institute's Resources allocation when system performs this statement, application completes.When expression formula X is true time, whole processor active task terminates.To job invocation, person sends end mark.

1.3. gordian technique

1.3.1 tasks in parallel

NBFS Parallel Scheduling language, task nexus is described, by the tasks at different levels in natural for the decomposition of people to problem corresponding program, multiple programming is natural, clear, simultaneously, tasks in parallel combines the advantage of data parallel and function parallelization, in support compared with under the prerequisite of high degree of parallelism, effectively can process irregular problem.More conveniently serial program can be rewritten as concurrent program.System is packaged into different tasks to realize parallelization data and operation.When multiple task has same operation, different pieces of information realizes data parallel, and when multiple task has different operating, practical function walks abreast.Each task is divided less than a BFS node, distributed parallel computing based on Scilab can be expanded and property computing environment develops formula HTB Hart payment space to OPENHTB() network node is in the Wide Area Network of parallel computational nodes, like this, can the task of parallel computation can be distributed on BFS on multiple computational resource, system performance will improve greatly.

1.3.2 system communication

System communication relates to two aspects: one is the communication between parallel computational nodes, and the data communication mainly completed between the BFS service on each BFS computing node of parallel computation exchanges with synchronizing information, and another is that BFS serves between client and communicates.Can be used for realizing communication and BFS between BFS service to serve and the communicating of client.Communication equipment is shaped with two kinds of implementation methods: PUII method and PUSH method.Wherein push method allows data to transmit together with notice, and this communication mode efficiency is high, for this feature performance benefit demand of parallel computation, can adopt in this way.In addition, because BFS service is that therefore, communication efficiency is higher based on this bottom communication mode of TCP/IP.

In order to realize the communication of NBFS under internet, NBFS have employed SOAPV1.2 standard and encapsulates it.SOAPV1.2 is loose at one, uses the switching fabric of XML equity and typed information to provide a simple and mechanism for lightweight in the environment of distribution.SOAP itself is not any applicational language of definition, he just defines a kind of simple mechanism, makes it can by very eurypalynous system for the extension of (Remote Procedure Call) from message system to RPC by this ability of a modular packaging.

NBFS extends Scilab and encapsulates SOAP, adds the data manipulation instruction of SOAP-EH, NHCS-SOAPEH in Scilab, makes user can data message in each data buffer storage of access system, realizes the transparency of distributed memory to user.NHCS-SOAP command N HCS-SOAEH.

There are two parameters: [TYPE] determines the operation model that system performs: digital independent or data write: [Name] is for needing name variable to be processed, by the string representation of taking the lead with letter, be expressed as data pointer operation when adding " # " above, before operate without representative value during " # ".

1.3.3 fault tolerant mechanism

Perfect condition lower network has following characteristics: shorter communication delay, higher communication bandwidth, extremely low error rate, good extendability.And reality is the time delay being difficult to tolerate, limited bandwidth, possiblely at random makes mistakes, and the distributed parallel computing knee pain therefore set up based on internet must have a set of fault tolerant mechanism corresponding with unit to adapt to.This computing environment is formed by connecting by some the computing machine Internet distributed.The fault of a unit or resource does not affect the normal function of other resources in theory, can realize the fault-tolerant of BFS by the inspection of the overall situation.But it is large to realize difficulty.Feasible method realizes fault-tolerant function by application program itself, when can break down again, unserviceable fault detector cannot solve NB-AC problem, so to weakening his non-trivial condition, obtain NB-WAC problem, then with HB by his reduction to consistent desirable problem, then solve consistent desirable problem with HB, thus complete solving NB-WAC problem.Use HB to solve, NB-WAC problem can be solved in the Asynchronous message transfer system comprising process failure and link failure, and other known at present traditional fault detectors can only solve the NB-WAC problem only comprising process failure.The method is applicable to often pair of different correct process all by a BFS expanding channels situation, thus realizes the fault-tolerant object of BFS.

1.3.4 safety problem

Owing to adopting SOAP to carry out bottom communication, NBFS applies the scope that can dispose and greatly expands, but can hardly be avoided in exposed node address in operational process, and node security problem and problem of data safety become the subject matter that system for restricting is disposed.The strategy that can adopt at present is limited not transferable trust principle, and the trust of node to master control system is distributed in units of task, and mission script can not the file system of access node, can only read and write the internal memory that system specifies.

2. the MVC pattern implementation of the support multiple terminals of all the other XML models

Current most typical a kind of MVC pattern implementation is the J2EE technology that make use of SUN company.J2EE technology mainly comprises Servlet.JSP.Java Bean.EJB, the parts such as Filter.In MVC pattern realizes, general JSP respective view, the interface that system is provided by JSP is come and user interactions.The corresponding model of JavaBean or EJB, process service logic, controller realizes, as the hinge between model and view due to Servlet.But, this implementation has following weak point:

Because JSP embeds Java language in the page, cause the mixing of view and controller, destroy the style of MCG Design Mode, the defect of this mode makes exploitation and maintenance become very difficult.

This implementation can support multiple client browser type, but all wants a presentation layer interface for each specific client type.Such as identical service logic, for one side browser, needs a set of JSP to form the presentation layer view of html format.And for the mobile phone using Hart to pay space, then need other a set of JSP to generate the presentation layer view of HIEP form.Code redundancy, not easily spreads.

JavaBean or EJB is generally relevant to specific database, if change or add data resource type or need multiple isomeric data resources integration, then may need again to rewrite code, reusability and extendability poor.

For this reason, consider BFS faced by be one and physically disperse, allos, the data environment of isomery and different terminal users, realize data sharing with mutual to be competent between different application systems or between different pieces of information source, namely client and server end bi-directional data exchanges.Adopt a kind of implementation based on XML model, namely XML virtual data base is used to replace JavaBean/EJB as the model realization of MVC pattern, simultaneously, by TIM terminal identification module J2MEMIDP(mobile middleware platform) identification terminal type, and unified by XSLT style sheet conversion processor dynamically to generate the final view being applicable to terminal demonstration.

System architecture as shown in Figure 10, gives the MVC pattern implementation of XML model.

2.1 design and implimentation

2.1.1 controller partial design

Controller has still been come by Servlet, and its implementation procedure is as follows:

Obtain the request (client can be desktop browsers, collection or PDA product etc.) from client

TIM terminal identification module J2ME(cell phone platform) judge terminal type by catching HTTP request head.In HTTP request, show between UserAgent HTB(MIDP mobile information apparatus) Accept(user terminal acceptable MIME file type) these two message headers are relevant with terminal type.By safeguarding that the dictionary of a User-Agent and acceptable mime type has carried out the identification of paired terminal.

Access model data XML virtual data base.

Put in context object or request session by terminal type recognition result and to the result data of XML virtual data base access, visit for View component.Control is handed to view to process.

2.1.2 modelling

It is an XML virtual data base design and implimentation shown in Figure 11.

Realize XML virtual data base by XML virtual data base and serve as data bus, completing with real data resource (can be various traditional relational, pure XML document or other resource types) mutual, mask the difference of each data source, consistent Data View is provided.If XML virtual data base provides necessary data converting function or instrument, carry out the mutual conversion of each resource and XML format data, and maintain the mapping relations between XML data and each heterogeneous data source.

XML virtual data base accepts XML format request from control, and it is corresponding to generate XML format, for View component.Its core is: virtual data base engine and data integration configuration documentation.

Data integration configuration documentation

Data integration configuration documentation is a self-defining XML format configuration file, and it occupies very important position in virtual data, it defines request, the syntactic structure of response document, and dynamic queries is decomposed, and merges rule and the associative operation to database.Essential element and the property value of this configuration documentation are as shown in table 1 below:

In table, </htbdate element with/HTBQUERY> element is similar.

Virtual data base engine parses data integration configuration documentation, and according to the configuration information after resolving, request is verified, decompose, perform, merge, and the XML document of final form format specification.The difference shielding each heterogeneous data source mainly here completes.

2.2 view

View be the appearance of model in performance, by xslt processor, and in conjunction with XSLT(Extensible Stylesheet Language, extensible style language) pattern unifies dynamically to generate the view being applicable to terminal demonstration.

XSL style sheet is used for defining a series of transformation rule, describes how to show XML document.Xslt processor provides a kind of general method, source XML document can be converted into the output format that various client terminal can identify, comprise the form of HTML-HIEP.The output format of xslt processor is determined by the transformation rule of XSL style definitions.Different client types, corresponding XSL style sheet is different.

Generate the process being finally supplied to the view of user as follows:

XML business datum and user terminal browser type is obtained from context or session.

The XSL style sheet suitable according to browser terminal type selecting, and after xslt processor carries out format conversion processing to XML business datum, form the format view of final HTML-HIEP.

View is submitted to client device.

2.3 these structural advantages

Model uses XML virtual data base, if need to add resource type, so only need increase the mapping of XML virtual data base and this kind of data resource and change, and achieves data resource and namely broadcasts and namely use.

Be embedded in Java code with JSP in current typical MVC pattern implementation, thus cause controller to mix different from view.This structure kind, the XML style sheet in view is only used for defining display format, realizes user-interface design, thus achieves model, controller, the thorough separation of view.Such developer can clear Partition of role, and each several part obtains importance amount of money maintainability and greatly improves.

In addition, this framework adopts unified mode to have xslt processor to carry out conversion process, generates the final view being applicable to terminal demonstration.Such system represents that layer interface just can support multiple client terminal.When needing to add new client type, without the need to changing presentation layer interface, only need increase corresponding XSL style sheet, code is simple and clear very, and can obtain better modularization and retractility.Open the demonstration at EPC services interface as shown in figure 12.
