Embodiment
As shown in Figure 2, network management system of the present invention comprises:
Foreground process, main responsible mutual with the software systems users' interfaces; As typing user's operation requests and be sent to background process, the data on backstage are presented on the terminal in the understandable mode of user.
Background process mainly is responsible for data interaction, logical transition between presentation layer (being the foreground process part) and the database.As the operation requests of sending on the presentation layer being carried out logic analysis, taking out and translate into form that presentation layer needs or the like with the mutual of equipment and with information in equipment, the database.As shown in Figure 3, background process of the present invention is made up of supporting layer, core layer, interface layer, functional module, wherein supporting layer has encapsulated the basic function that background process need use, as application programming interfaces API such as operation log recording, database manipulations, provide as the instrument that needs to use in the background process exploitation.Core layer is responsible for dispatching the operation of each functional module in the background process, dispatches the processing method of the corresponding function module as the command messages that sends according to the foreground.Core layer is responsible for the processing of process internal event and message simultaneously, as notifying each functional module with the communication disconnected event of interface layer, so that each functional module is according to carrying out running status process relevant treatment.Interface layer be responsible for other processes between communicate by letter, as receive command messages from other modules, to other modules transmission message or response message etc.Interface layer is in charge of the communications status with other processes simultaneously, and when disconnecting with communicating to connect of other processes as discovery, the notice core layer is handled.Functional module is articulated on the core layer by the means of log-in command word or registered events, and the functional module application programming interfaces API that calls supporting layer, interface layer finishes the operation in the storehouse that reads and writes data and mutual with other process.The design that is to say background process of the present invention is exactly that a background process is divided into the background process general framework of being made up of supporting layer, core layer, interface layer, four parts of functional module.Background process provides support the service of layer, core layer, interface layer with the form of Static-link Library and Dynamic-link simultaneously, promptly provide a cover to be used for the static library of background process general framework design as its using method, with the data interaction of background process and other processes, the general operation of all general character such as scheduling of the accessing operation of database, software function module is encapsulated, with C
++The form in static function storehouse provides application programming interfaces API; The application programming interfaces API that utilizes this static library to provide, make other software developers energy can be concentrated on the design of software function module, make the peopleware only need design relevant functional module according to the function that the process needs are realized, and be articulated on the background process general framework it just passable, promptly the method that provides by the background process general framework is registered the function that this module need realize to the background process general framework.Thereby can significantly reduce the design work amount of background process, design as a topological background process, need not be concerned about database manipulation, with how realizing alternately of other processes, only need be according to a topological functions module of Demand Design on topological backstage, in this module, finish the interrelated logic operation of topological functions, as the additions and deletions node, view management etc. (the supporting layer function that can use the background process general framework to provide in this process), and be articulated on the background process general framework, finish scheduling by the background process general framework, just can realize a complete background process the topological functions module.And need not be concerned about such as details such as interprocess communication/database manipulations; And can be easily oneself functional module be articulated on the background process general framework, thereby constitute a complete background process.So abundant assurance developer only need realize concrete functional module, by means such as log-in command words it is articulated on the core layer, thereby the assurance background process can be finished the scheduling of functional module easily.Simultaneously the API that can use supporting layer, interface layer to provide in the design of functional module finishes such as the operation in the storehouse that reads and writes data and mutual with other processes.Such architecture makes the expansion of new function become convenient, thereby has reduced software development cost, has improved efficiency of software.Keep-alive and the Restoration Mechanism of a kind of TCP/IP are provided in background process simultaneously, so-called keepalive mechanism, the two ends that refer to a TCP/IP link possess the periodic monitor opposite end and whether move normal ability.As monitor link the other side and closed this link, or occur unusually, should be able to discharge the related system resource automatically, and system running state is returned to normally, also promptly so-called recovery mechanism.ICP/IP protocol itself provides a kind of keepalive mechanism, but depends on the difference that operating system realizes, the time interval of keep-alive and the processing of recovery are also not quite alike.But for making software systems possess stronger consistency, unlikely because the upgrading of operating system or migration cause the unusual of running software, background process of the present invention promptly provides the keepalive mechanism of oneself, also is the keepalive mechanism of application layer.TCP/IP connection the carrying out timing that the static library that its implementation provides for background process is responsible for this process is set up is monitored, and this timing can dispose.As monitor the TCP/IP link interruption, then discharge system resources such as the port that takies on the peer link, internal memory, thread, and according to other recovery operations of determining positions in network connects of this process.As this process is client process, then sets up the link to server end again automatically.When abnormal termination phenomenon appearred in part webmaster background application, keepalive mechanism can guarantee that the application safety of being correlated with stops, and has avoided occurring the influence that unusual part is used other webmasters as much as possible.When the abnormal restarting phenomenon appearred in part webmaster background application, keep-alive and Restoration Mechanism can make system need not artificial intervention, quickly recover to normal operating condition, had reduced the influence that operation causes to network management system unusually as much as possible.Simultaneously, this mechanism is for safeguarding under the condition of running without interruption and upgrading network management system partial function provides guarantee.
Database mainly is responsible for the storage administration of data, and it mainly comprises the database table structure, storing process etc. of network management system.
Of the present inventionly focus on being provided with between this background process and the foreground process the isolated foreground process that constitutes by network interface backstage and event center and the flexible bus of background process, and adopt extending mark language XML report between network interface backstage and event center and foreground process and the background process as the interface packets formal definition standard between process, it is the message that transmits the XML form between process by TCP/IP, and the XML message that receives resolved, obtain information wherein.Because the XML report is an extending mark language, is one of current international practice standard of present SGML, has extremely strong expression ability, can carry the data message of large amount of complex.Thereby effectively utilize the XML report as the process interface.With the interface that standard is provided, opens to the third party easily.Background process is by registering the command word that needs so that the service that Mk system can provide is adopted multithreading simultaneous operation technology thereby make between foreground process and the background process to the network interface backstage; Owing to realize the needs of function according to program, a plurality of threads in process need be visited identical physical resource when operation, as internal memory, TCP/IP port, file etc.For avoiding a plurality of threads to read while write the entanglement that shared resource causes data, need carry out Synchronization Control to the visit of resource.When as a thread certain shared resource being write, other all concurrent write operations all must be clogged to could be carried out after current write operation finishes.So this Synchronization Control of the present invention by background process guarantee semaphore, mutual exclusion lock etc. synchronously object can reliably realize.Background process comes the various asynchronous events in the treatment system to pass through by the event type that needs to handle to the event center registration simultaneously, and the information interaction of foreground process and background process is distributed by command word and event type by network interface backstage and event center.
