Embodiment
Be described in detail as follows with regard to the preferred embodiments of the present invention below in conjunction with accompanying drawing.
The COM+Event know-why is introduced
(COM+Events is the Event Service that Microsoft provides in the COM technology to COM+Events, realized the subscription and the notification triggers of incident under distributed environment) subscription/publication that can realization event, it is a loosely coupled event (LCE:Loose Couple Event loosely coupled event, the subscriber of self-explanatory characters' part and recipient can exist simultaneously, loose incidence relation) system, system can preserve a plurality of publishers' event information, the subscriber inquires about own interested event object and subscribes to, when incident takes place, system looks is notified by the method for calling the subscriber this interested subscriber.
What COM+Events permission publisher separated with the subscriber develops, issues and carry out, and subscriber and publisher are by COM+Events opening relationships, and when the subscriber subscribed to incident, the publisher did not need to be in active state.
The realization principle of network element data Synchronization Component just is being based on above-mentioned COM+ know-why, by subscription to the interested subscriber of some configuration data of network element, after revising, calls configuration data the data that the com interface issue is modified then, so that in time notify the variation of subscriber's data.
The COM of network element internal real time data realizes:
General network element is by configuration, alarm, performance, functional modules such as maintenance are formed, and the data of network element also are made of these aspects basically, not again mutually independently each other simultaneously, certain influence is arranged each other, particularly the modification of configuration data has influence on the information that is shown to the user possibly, for example: the title that comprises the equipment of forming network element in the configuration data, after this part data is revised, with the correctness that has influence in the alarm that is shown to the user about device name, synchronization notice is to the part of being concerned about these configurations when just needing network element configuration take place to revise in this case, guarantees the consistency of data and refreshes in real time.
The subscription/publication service of COM+ has just in time solved this problem for us, the part of being concerned about configuration variation is the subscriber, and the part of generation configuration modification is as publisher (informant), by subscribing to both are connected, COM+Event is in charge of subscriber and the interactional relation of publisher, the alarm demonstration can be used as the subscriber in the top example, tell the configuration section configuration that it is concerned about, configuration section is as the publisher of notice, after revising, the data that alarm is concerned about notify timely, implementation procedure is seen Fig. 1, and the specific implementation process is as follows:
(1) during system start-up, publisher's (being network element configuration among the embodiment) at first can create event object (be used for being configured synchronous), and (CataLog is the meaning in storehouse by subscribing this object to be registered to COM+Catalog, refer to preserve the database of subscription information here) the storehouse in, this assembly is used to trigger amendment advice, and notifies the subscriber (being network element alarming among the embodiment).
(2) notice is subscribed to, subscriber's (being network element alarming among the embodiment) at first provides the data of oneself being concerned about (for example configuration) by subscribing interface, pass through character string identification, the interface pointer of processing notification data and the ID of the event object of correspondence are provided then, so just between incident and subscriber, have set up subscribing relationship.
The data of subscribing to need be harmonious with the data publisher, and for example network element alarming provides the data table name that oneself is concerned about, network element configuration will be carried out Refresh Data by the notice network element alarming when this table takes place to revise.
