Description
Technical field
The present invention relates to the foundation structure of Message Processing, relate in particular to message switching apparatus and switching method in a kind of distributed environment.
Background technology
Message generally is that application system inside is sent to the another one assembly from an assembly, perhaps be sent to the information unit of Another application system from an application system, message is the means of communication between component software or the application system, and message is the central topic of application system integration.
Message must be the height architectureization, like this could analyzed and understanding.This architecture use abstractdesription the structured documents of message element between service and solution development personnel, communicate.The key message that comprises in the message structure has: whether masurium, data type (for example, integer), value constraint (for example, the integer of expression percentage requires between 0 to 100) and element are essential etc.
The message form comprises incident, monologue, request response, dialogue, session.Our the most familiar message form is the request response: the sender opens a connection to receiving port, sends message, receives affirmation then.Real process is usually more complicated, and the transmission of message will be passed through the intermediate layer usually, for example, and high-speed cache, filter fire-proof wall and voucher management system.These intermediate layers can be described as will intercept message, to carry out section processes or complete process.The intermediate layer may produce unusually, and for example, the mandate intermediate layer of denied access request causes returning to mistake of sender.
Intercepting is the basis of message, and sender of the message and message acceptance person must intercept message, and just because of intercepting, message is able to the path route along complexity, so that dedicated system can participate in Message Processing.Intercepting a more common application is, uses different message formats to ask conversion between application system.This pattern both can be used for providing standard compliant interface in the front of the system that uses proprietary protocol, can be used for changing the message of the service agreement of observing out-of-date version again.
As mentioned above, message switching apparatus is used to finish the search message route, message transmits and processing, and under distributed environment, the application system major part all is foreign peoples's a system in addition, comprises that message structure all is the foreign peoples, also needs to carry out the conversion of message structure.But these three links all are to seem the very complicated link of simple reality.The definition of message structure and the application system in the distributed environment itself is closely related, and the selection of message route relates to basic communication structure, and Message Processing is owing to the restriction of distributed environment becomes difficult unusually.
As shown in Figure 1, what have the message dedicated system now generally is network structure, the system of each manufacturer is independent separately, and also there is more system independently mutually each manufacturer inside, if integrate, generally independently increase in the system and the interface of another one autonomous system, as the 110-114 interface among the figure at each, the 114-billing interface, 1000-97 interface or the like.
This dedicated system can participate in Message Processing, but has following shortcoming: because the unreliability of Network Transmission (the especially transmission between heterogeneous network) is made mistakes in the message exchange procedure easily, cause a plurality of replying or no response of message; Secondly, because the selection mistake of route control strategy causes message to arrive each message recipient according to Business Processing sequencing (operation flow), or message recipient receives the message of incorrect order, or the transfer path confusion of message.
Therefore be necessary to provide new message switching method and the device that uses in a kind of distributed environment, can eliminate preceding two shortcomings, the while is simple in structure, does not influence the speed of message.

Embodiment
With reference to the accompanying drawings embodiments of the invention are elaborated.
Fig. 2 is the structured flowchart of present embodiment message switching apparatus, only shows the structure of module one-level among the figure.As shown in the figure, this message switching apparatus comprises message control module, name server, message routing module control and a plurality of node adaptation module.Each node adaptation module all is connected to a foreign peoples or similar application system, and name server, message routing module control and each node adaptation module are connected with the message control module respectively.Wherein:
Node adaptation module (NAM) adapts to the application-specific system, and the Message Agent operation of application system and message control module is provided.Further comprise: the register requirement unit is used for initiating or transmit register requirement (can carry out to the short connection of message control module by the node adaptation module) to the message control module; Dispatch Unit is used for the message stores that the source application system is sent is forwarded to the message control module, and the message stores that the message control module is sent is forwarded to corresponding application system, and the message of forwarding mainly is Business Processing message and relevant response message; And the Structure Conversion unit, be used between the application system or the message format between message control module and the application system not simultaneously, finish the conversion operations of message format.
The present embodiment device is used under the distributed environment, and the application system major part under this environment all is foreign peoples's a system, comprises that message structure all is the foreign peoples, so message conversion is important link.Fig. 3 has showed the transfer process example between two kinds of message formats.Figure is the source data conversion at the middle and upper levels, wherein the left side is the information field in the message structure, the centre is " type of service " element format in the message of application system 1, and the right side is " processing type " element format in the message of application system 2, and in fact implication is identical for these two kinds of elements.Lower floor is a data transaction among the figure, and wherein middle is the value of application system 1 " type of service " element, and the right side is the value of application system 1 " processing type " element.
This device of present embodiment can self-defined a kind of standard message structure, perhaps selects the existing standard message structure as this device internal default structure, adopts with the application system (also having the application system of transforming) of exploitation after an action of the bowels.Just can to select this relatively more excellent message format be its default message form to the message control module like this, and the message conversion example among the figure has represented that also the message format of message control module and the message format of application system change.
The message routing module control is used for after the routing inquiry request of receiving the message control module, and carry out automatic route judgement or the message path is set according to information receiving and transmitting person identity and predefined type of service, and return results.The application system domain name can reach Route Selection control purpose by the assistance messages routing module control.Message can be divided into following five kinds of situations:
1) only relate to two application systems, unidirectional, the message route is: domain name 1 → domain name 2.
2) only relate to two application systems, but two-way, the message route is: domain name 1 → domain name 2 → domain name 1.
3) relate to a plurality of application systems, unidirectional, the message route is: domain name 1 → domain name 2 → domain name 3 → ... → domain name n.
4) relate to a plurality of application systems, two-way, the message route is: domain name 1 → domain name 2 → domain name 3 → ... → domain name n → domain name n-1 → ... → domain name 1.
5) relate to a plurality of application systems, part is two-way, and the message route is: domain name 1 → domain name 2 → domain name ... → domain name n → ... → domain name k.
Automatically the route arbitration functions is used for very simple situation, relatively is convenient to automatic judgement such as the message situation between two application systems, can directly provide the target application system that needs forwarding.But, the message routing module control needs according to information receiving and transmitting person identity and predefined type of service the message path to be set more frequently, be the schematic diagram of a Route Selection as shown in Figure 4, the route list of having represented a business in the schematic diagram, use domain name to represent application system, domain name mapping function by name server can the location node adaptation module the position, thereby find the position of target application system.
The message route is different with the IP route, the message route is the path of message, if a certain application system in the professional route list is to disapprove state or a link is therein made mistakes, then should business not handle, belong to abnormality, the alternate routing that also can increase after unusual improves reliability.In addition, after certain application system is handled, the result data that obtains can be encapsulated in and issue the message control module in the response message, the message control module need be rewritten the message of issuing this application system according to route, comprise destination address (changing the address of next application system into), data volume (result that has just obtained) etc., issue next application system then, up to the terminal point of route.
Name server (DNS) is used to provide the function of similar general domain name resolution server, and in the present embodiment, the domain name of application system is that the overall situation is unique, is made up of module title and global unique sign (GUID) of corresponding node adaptation module.Clauses and subclauses during domain name approaches corresponding to domain name server address, as shown in Figure 5, these clauses and subclauses comprise domain name, computer address, listening port, process number, thread number etc., and these information relation of having levels singly is that possibly of address can't the position application system.
On function, can be further divided into domain name registration unit, domain name mapping unit and information updating unit to name server.Wherein, the domain name registration unit is used for when receiving register requirement, whether legal according to the domain name judgement that the domain name or the message control module of the request of node adaptation module are distributed, such as checking whether domain name repeats, whether computer address is correct etc., if legal then add respective entries on address book, the notification message control module succeeds in registration then, otherwise directly notifies registration failure.Domain name in a single day registration can not nullified easily, if application system is owing to reasons such as inefficacy need to nullify, and manual cancellation on name server so; If because reasons such as illegal, network failures, application system is unavailable, revises this domain name state so for disapproving, and do not nullify.
The domain name mapping unit is used for the request according to the message control module, parses one or more item of information in the address book domain name relevant entry.When transmitting message in the decision process of domain name registration with according to the application system domain name in the route, be all key messages that are used to parse this domain name correspondence, wherein the IP address is indispensable, and when Business Processing relates to message, because long the connection sets up, so analysis result mainly is the state of the application system of domain name correspondence.Whether the permission in the address book/disapprove this application system of state representation is in state available or that allow others to use, and disapproving may be because long the connection such as disconnects, this application system is illegal at reason.In addition, the domain name mapping unit also after receiving the reverse resolution request that the message control module sends, goes out domain name, the return messages control module according to information reverse resolutions such as node adaptation module title, address, process numbers.
Information updating unit is used for the notice according to the message control module, the corresponding information item during scheduler is thin, for example according to notice with the status modifier of application system for disapproving etc.
Message control module (MCM) comprises further and long the connection sets up unit, long connection management unit and message control unit that message control module and each intermodule exist request message and response message all the time.Wherein:
The long connection sets up long connection the (node adaptation module and application system are man-to-man, and connection wherein can be short the connection or the length connection, and the present invention does not do qualification) that the unit is used to set up message control module and node adaptation module.In the present embodiment, long connect set up the unit can initiate to set up long connection the: A under the following situation, after the node adaptation module succeeds in registration; B carries out reverse resolution at the long disconnection back request name server that connects, and initiates the long of the several times application system corresponding with the gained domain name again and connects; C is not having according to route under the corresponding long situation about connecting at the message control unit, can set up subelement by connection and initiate to set up long connection the, back and application corresponding systems exchange message earlier.
Long connection management unit is used to monitor the long state that connects, long connect initiatively disconnect because of the node adaptation module or network interruption etc. is former thus disconnect after, the long connection of triggering set up unit trial recovery connection (can carry out several times), if failure, notice name server with the status modifier of corresponding application system for disapproving.
The message control unit is used for finishing the functions such as legitimate verification, state verification, routing inquiry and exchange control of register requirement and Business Processing, comprises again:
The registration control sub unit, be used for after the login request message of receiving the node adaptation module, being forwarded to name server, if name server returns failed message, send error message then for the node adaptation module, set up the unit and set up with the length of this node adaptation module and be connected otherwise trigger long the connection;
The state verification subelement is used to ask the domain name server parses to go out the state of application system, and receives the state information of returning;
The routing inquiry subelement is used for sending routing inquiry request to the message routing module control, information such as the transmitting-receiving person's identity that in request, gives information (being domain name), predefined type of service, and receive the routing inquiry result;
The Business Processing subelement, be used for after receiving the Business Processing message that the node adaptation module is transmitted, trigger the inquiry route and to using the checking of system mode, first application system in route sends message, after obtaining replying, rewrite message and be transmitted to next application system, up to message route terminal point; If a certain application system state in source application system or the route is made mistakes when disapproving or handling, then this service fail.Above-mentioned registration control sub unit and state verification subelement also play the effect of the information receiving and transmitting person being carried out identity validation, further can also increase authentication functions such as authority, licence.
The message Route Selection of present embodiment is to decide and send a message to next node according to the message path (similar routing table) of predefine or dynamically generation, and the node here is meant the application system of managing business, and is not the address of next router.Present embodiment provides a concentrated routing module control to decide feasible path, does not have conventional router to be responsible for the function of transmit information data bag.
Distribute a global domain name because special-purpose name server is an application system, in fact simplify the Classification Management of application system and relevant information thereof, also simplified the message Route Selection simultaneously.Because the message control module must have the long foundation that is connected with the node adaptation module in message, domain name also has man-to-man relation with long the connection, so the selection speed of data link must be accelerated.The route of routing module control is no matter be predefined or dynamic the generation, it all is the chained list of the domain name of a series of application systems, the message control module produces the long chained list that connects between message control module and the node adaptation module according to this chained list, the long application system that connects direct location node adaptation module agency herein, thus determine a complete message transfer path.Domain name is to the location of node adaptation module, exactly by using domain name--〉system--〉node adaptation module among Fig. 4--〉and the correlation of long connection establishes.
As shown in Figure 6,110 receive the people's of a hand-set from stolen alarm call, and 110 forward the true identity and the operator of the stolen number of 114 inquiries after putting on record to, forward 1000 then to and report the loss shutdown, forward 110 places at last to.The message transfer path is 110 → message control module → 114 → message control module → 1000 → message control module → 110.
The present embodiment device can use one or more between the of the same race or xenogenesis application system in distributed computing environment (DCE), communication basis as each application system in the distributed environment, be equivalent to be connected in the another one said apparatus as an application system for each application system provides bus-type message structure.
Be the flow chart of present embodiment method application system registration as shown in Figure 7, may further comprise the steps:
Step 180 after the message control module is received the message of registration failure, sends registration failure message to the node adaptation module.
Be the message flow chart that the present embodiment method is crossed over the application system Business Processing as shown in Figure 8, may further comprise the steps:
When step 220, source application system need other application systems to manage business, send the Business Processing request to corresponding node adaptation module;
After step 240, message control module received this forwarding message, the License Status by name server checking source application system then returned error message to the node adaptation module if disapprove, otherwise carries out next step;
Step 290 after the message control module is received this response message, judges whether needs to next target application system forwards according to route, if need, carries out next step, otherwise has arrived message route terminal point, finishes;
If Business Processing successfully or after makeing mistakes in follow-up link, the message control module also can return success or failed message to initial node adaptation module.In addition, in above-mentioned steps 260, if there is the target application system of the state that disapproves, also can attempts earlier setting up with the long of its and is connected, if successfully, then continue execution in step 270.
Except above-mentioned flow process, the present embodiment message switching apparatus is in running, if because network failure causes long the connection to disconnect, and the domain name mapping result is not temporarily stored in the message control module, then carries out following handling process:
The message control module monitor and the node adaptation module between disconnect long the connection, send the reverse resolution request to name server, information such as node adaptation module title, address, process number are provided;
Name server goes out corresponding domain name according to the clauses and subclauses reverse resolution in the address book, the return messages control module after receiving this reverse resolution request;
The long of node adaptation module that the message control module attempts recovering corresponding with the gained domain name connects (can carry out repeatedly), if successful connection then finishes, otherwise carries out next step;
Message control module notice name server with the status modifier of corresponding application system for disapproving.
After if long connection disconnects, temporary in the message control module have the domain name mapping result, just there is no need to resolve domain name.
