Description
Technical field
The present invention relates to the method in network management technology field, particularly network management data synchronous refreshing and the system of network management data synchronous refreshing.
Background technology
Network management system is called for short network management system, be the software systems that various telecommunication apparatus are managed, network management system has realized the centralized management to various telecommunication apparatus, and topography module offers user's an important operation man-machine interface as network management system, allow the user equipment, connection etc. to be opened up and mend object and operate, and finish mutual with background server by this interface.For in the quick response telecom operators maintenance process to the response speed of work such as telecommunication apparatus, network operation, topography module adopts the means of client-cache partial data on data distribute, cause delay on the network interaction to reduce the data change that causes because of operation.Along with the development and the expansion of telecom operators' business, the number of devices that network management system is managed is also increasing, and the device data amount in the Dui Ying network management system is also increasing thereupon with it; And, all may cause the attribute change of telecommunication apparatus data for Business Processing such as the configuration of telecommunication apparatus, maintenance, monitoring, service dispense, and the user of client itself operates, and also can cause the attribute of partial data to change.Attribute described here comprises title, coordinate position, icon style, text description and the gentlemen of equipment.Normally, off-line, the various states of fault or the like.As main topological data synchronization means, be that the user solves a kind of function easily and efficiently of opening up benefit server end and client data difference.And under the large-scale data environment, how to realize the immediate problem that data sync has fast and accurately just become the network management system topography module to be faced.
Client comprises client database, data management module, control module, view control module etc., and wherein control module also comprises message sink module and message transmission module; Server end comprises server end database, data management module, control module etc., and control module also comprises message sink module and message transmission module.Between the client and server end, can also comprise the message distribution module that is used for dispatch messages.When prior art is carried out data synchronous refreshing at needs, at first at the local data of client by data management module full scale clearance client, and by the demonstration of view control module removing view, again talk from server end then and get total data, re-construct the local data of client again in client, repaint whole topological view by the view control module simultaneously.Prior art is by mutual based on massage pattern of client and server end; Can guarantee that server end when producing data change, can upgrade client data in client.But, in the ordinary course of things, client when carrying out the data sync refresh process, the discrepant just fraction data of itself and server end, carry out for a small amount of inconsistent data total data synchronously, obviously cost is relatively too high.
Summary of the invention
The present invention proposes a kind of method of network management data synchronous refreshing, data quantity transmitted during in order to the reduction network management data synchronous refreshing.Another object of the present invention is to propose a kind of webmaster and draws the system that data sync refreshes that pounces on.
The invention provides a kind of method of network management data synchronous refreshing, this method comprises: client sends to server end with the sign and the corresponding status indicator of client data; The server end comparing data identifies clients corresponding status indicator and server end status indicator, and returns the pairing server end data of the different Data Identification of above-mentioned status indicator to client; Client is upgraded local data according to the server end data of being received.
Beneficial effect of the present invention:
Server end database of the present invention is used for the storage server end data; The server end data management module; Be used for the data of server end database are read, increase, delete or revise; The server end control module is used for more described Data Identification clients corresponding status indicator and server end status indicator, and returns the pairing server end data of the different Data Identification of above-mentioned status indicator to client.Client data and server end data are provided with the status indicator of the current attribute status of expression, carrying out data sync when refreshing, client needs again the sign of client data and corresponding status indicator are sent to server end, relatively whether each Data Identification clients corresponding status indicator is identical with the server end status indicator for server end then, and returns the pairing server end data of the different Data Identification of above-mentioned status indicator to client; Client is according to the data of being received, upgrade local data, like this, when data sync refreshes, only transmitted the data that change, having significantly reduced data sync, to refresh the data volume that causes mutual, and therefore also having reduced data sync refreshes network consumption and the whole time loss that causes.Owing to reduced the caused whole time loss of data sync, thereby reduced the possibility that causes loss of traffic and function to omit in the data synchronization process.

Fig. 1 is a system configuration schematic diagram of the present invention.
Embodiment
The present invention carries out data sync when refreshing at the client and server end, by relatively, and data that there are differences synchronously only, and asynchronous identical data, thus reduce the data volume of synchronous refresh.Further, also just repaint the topological view part corresponding, mend the view refresh time, improved the efficient of refresh operation thereby reduced to open up with variance data in client.Client described here is meant Topology Foreground, and server end is meant to open up mends the backstage.
The embodiment of the invention is added status indicator by the data to the client and server end; In order to represent the change situation of attribute in each data.Status indicator can be used as the part of data.In addition, status indicator also can adopt the mode of correspondence table to unite preservation with corresponding Data Identification.In other words, in database, preserve the corresponding relation of data ID and status indicator.The mapping table of data ID and its status indicator.No matter be the part as data, still in mapping table, the value of status indicator can be preserved with the integer categorical data, can reduce the time complexity of internal memory, calculating and comparison like this.The status indicator of same data ID correspondence between the client and server end represents that then the data of this ID correspondence are variant not simultaneously, need carry out Synchronous Processing; When if the status indicator of the same data ID correspondence between the client and server end is identical, represent that then data not there are differences, so just do not need to carry out Synchronous Processing.The status indicator of data can be the timestamp of these data, also can be by certain algorithm computation, then can calculate the ID in the data and every combinations of attributes.
