Abstract
The data synchronization method includes following steps: after connecting to local network management (LNM), remote network management (RNM) inquires for unique id of the LNM; when opening up a data file, RNM inquires for MD5 value of corresponding data file in LNM; after obtaining MD5 value of LNM, RNM compares it with MD5 value of own data file; if result is not consistent, inquiring for compressed configuration file from LNM, RNM decompresses and saves the received configuration file. If modifying and saving data, RNM saves data file first, and inquires for MD5 value of corresponding data file in LNM. Then, RNM compares MD5 value in LNM with own MD5 value; if compared result is not consistent, then RNM sends compressed data file to LNM; after receiving file, LNM decompresses the file, and save decompressed file so as to realize data synchronization between RNM and LNM.

The purpose of this invention is to provide a kind of method of data synchronization of realizing remote network management.Be connected by Dial-up Network between remote network management of the present invention and the local network management, local network management is to be connected by the RS232 interface with network element.Be mutual mutually between remote network management and the local network management, the data file between them is consistent, realize the purpose of data sync by information data.
The concrete steps that realize purpose of the present invention are as follows:
At first, local network management confirms whether the unique identification that belongs to this webmaster is arranged when starting, then do not generate a unique identification; Remote network management and local network management start is connected after, ask for the unique identification of local network management, when remote network management is opened a certain data file, ask for the eap-message digest MD5 value R1 of the data file of correspondence in the local network management then.Remote network management obtain behind the MD5 value R1 of local network management with the MD5 value R2 of own data file relatively.If unanimity as a result, then remote network management directly shows the data file of oneself; If comparative result is inconsistent, the configuration file after local network management is asked for compression then, remote network management are received behind the configuration file decompress(ion) preservation of contracing.When the user when remote network management is revised data and is preserved, remote network management is preserved data file earlier, ask for then local network management corresponding data file MD5 value R1 and with oneself MD5 value R2 comparison.If comparative result is inconsistent, the data file after local network management sends compression then, local network management is received behind the file decompress(ion) preservation of contracing, and is consistent with the configuration data of the network element preserved on this configuration data that reaches the network element of preserving on the remote network management main frame and the local network management main frame.
Described unique identification has uniqueness at the local needs of each remote network management exactly, is convenient to remote network management identification local network management, is exactly the unique identification of remote network management according to local network management, deposit data different place in the file system, prevents to obscure.
Interface channel between described remote network management and the local network management, between local network management and the network element is not limited to top described, specifically is that what channel type does not influence enforcement of the present invention.
Beneficial effect of the present invention is the data sync that can simply and efficiently realize between remote network management and the local network management.
Description of drawings
Fig. 1 is the annexation schematic diagram of remote network management, local network management and network element.
It is identical that Fig. 2 asks for content data file for remote network management to local network management.
Fig. 3 asks for content data file for remote network management to local network management.
Fig. 4 preserves the situation of data file for the remote network management user.
Fig. 5 preserves the another kind of situation of data file for the remote network management user.
Embodiment
The invention provides a kind of method of data synchronization of realizing remote network management.This method is mutual mutually by the information data between remote network management and the local network management, and the data file between them is consistent, and realizes the purpose of data sync.Figure 1 shows that between remote network management and the local network management to be connected that local network management is to be connected by the RS232 interface with network element by Dial-up Network.Be mutual mutually between remote network management and the local network management, the data file between them is consistent, realize the purpose of data sync by information data.
Embodiment is described below in conjunction with the accompanying drawings:
Preceding 6 steps of each flow chart of Fig. 2～Fig. 5 are after local network management starts, and check whether the unique identification of local network management exists.Unique identification can leave in the specific file, or other places.If such sign does not exist, then generate a sign and preservation.This specific identifier need have uniqueness, can use the unified identifier (GUID) in the whole world.
With after local network management is connected, ask for unique identification at remote network management to local network management.Same remote network management may connect with a plurality of different local network managements constantly in difference, therefore need ask for the unique identification of local network management, is convenient to discern local network management.A kind of possible application is exactly the unique identification of remote network management according to local network management, deposit data different place in the file system, prevents to obscure.
Figure 2 shows that it is identical situation that remote network management is asked for content data file to local network management, when remote network management is opened a certain configuration data file, check whether the data file of this configuration data correspondence is consistent with the corresponding data file of local network management.It specifically is remote network management is asked for data file earlier to local network management MD5 (eap-message digest) value, local network management sends to remote network management after calculating the MD5 value, after remote network management is received this MD5 value, also calculate the MD5 value of the data file of oneself, relatively whether two MD5 values are consistent then.If unanimity as a result, then remote network management directly shows the data file of oneself, if inconsistent, then points out the user " data are inconsistent, whether cover the data of remote network management ".If the user selects "Yes", then forward next step to.
Figure 3 shows that remote network management asks for content data file to local network management, local network management elder generation compression data file transmits file after the compression then to remote network management.Remote network management receives the back decompress files and preserves, and covers original data file, and then the display file content.
Figure 4 shows that the remote network management user preserves the situation of data file.The user can revise data file at remote network management, (or the user does not revise data file during the operation of preserving file after modification finishes, directly preserve operation), remote network management is preserved file earlier, and then the MD5 value of asking for the corresponding data file to local network management.Remote network management is received from the MD5 value back of local network management and the MD5 value of the data file of oneself and is compared.If the comparative result unanimity is then done nothing, if inconsistent, then referring to Fig. 5.
Shown in Figure 5.At this moment suppose that remote network management is with on local network management is connected.Since the data file that the user preserves on the remote network management be different on the local network management, therefore, remote network management elder generation compressed file sends the data file of compression then to local network management.Local network management is received the preservation of contracing of the data file thing decompress(ion) of compression, covers original data file.So far, the present invention can simply and efficiently realize the data sync between remote network management and the local network management.
