Description
Technical field
The present invention relates to LAN data simultaneous techniques fields, and in particular to one kind is efficiently across the LAN data side of synchronization
Method.
Background technique
With informatization, the exchange transmission of data between networks is more aobvious frequent, based on to important department inside number
According to the consideration of safety, the isolation of physics is carried out to computer network, but this isolation is built upon sacrifice computer network
The convenience used is cost, thus greatly reduces working efficiency.In order to meet physically-isolated safe need between heterogeneous networks
The exchange of inter-network data safety is realized in summation, generallys use data individual event transmission technology, is the data information security of high security requirements
Work provides effective solution means, data individual event transmission, although the secrecy of data is ensured, in frequent data exchange
In the case where, working efficiency is lower.
Summary of the invention
It is an object of the invention to overcome problems of the prior art, provide a kind of efficiently same across LAN data
One step process, it may be implemented effectively to guarantee the synchronous confidentiality of data, is uploaded multiple packets respectively using FTP, and Intranet end can be with
It is quick-downloading, while multiple threads synchronize update, avoid the obstruction of data synchronization process.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved by the following technical solutions:
A kind of efficiently across LAN data synchronous method comprising following steps:
Step 1 sets up two-way isolation gap between local area network and public network；
Step 2, configuration mirroring: configuring public network end and gateway Data entries address is A, gateway and public network data outlet address
For B, gateway and intranet data exit address are C, and intranet data and gateway data outlet address are D, and configuration access A, B, C, D are each
The user name and password of address, the address mirroring of configuration C and A address mirroring, D and B；
Step 3, public network are synchronous to Intranet, specifically comprise the following steps:
Step 3.1 formats the data for needing synchronization；
Step 3.2, the ZIP file that formatted data are packaged into encryption；
The ZIP file that step 3.3, starting thread upload encryption with FTP connection type is deleted after uploading successfully to the address A
ZIP file；
Step 3.4, Intranet program starting thread, from the address C, are downloaded file and are saved in specific bit in a manner of FTP downloading
It sets；
Step 3.5, decompression thread monitor download location decompress file, identification file mark, and synchronized update is corresponding
Database table deletes source data file after the completion of updating；
Step 4, parsing data simultaneously establish index: parsing formatted data in the step 3.1 and be stored in memory
In, database level establishes unique field index；
Step 5, Intranet are synchronous to public network: the data format that needs are transmitted, ciphered compressed generate the text of ZIP format
Part；
Step 6, FTP connection transmit files to the address D；
Step 7, outer net FTP obtain the formatted file transmitted from Intranet to outer net from the address B.
Preferably, synchronous data format will be needed to turn to JSON format in the step 3.1, monofile number of data exists
In 100~500, and the rule name file name mutually to appoint.
Preferably, XML format is melted into the data format that needs transmit in the step 5.
Further, formatted data are named in the step 3.1, and naming rule need to have uniquely
Property.
Beneficial effects of the present invention: by setting up gateway between public network, local area network and carrying out data transmission, object is used in realization
Reason isolating means carry out data transmission, ensure that data transmission when safely controllable property, while also meet high private data across
Network data demand；Database level establishes unique field index, the high efficiency of improve data transfer process.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram efficiently across LAN data synchronous method of the present invention.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below will
In conjunction with the attached drawing in the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that
Described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the implementation in the present invention
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The scope of protection of the invention.
Efficiently across the LAN data synchronous method of one kind as shown in Figure 1 comprising following steps:
Step 1 sets up two-way isolation gap between local area network and public network；
Step 2, configuration mirroring: configuring public network end and gateway Data entries address is A, gateway and public network data outlet address
For B, gateway and intranet data exit address are C, and intranet data and gateway data outlet address are D, and configuration access A, B, C, D are each
The user name and password of address, the address mirroring of configuration C and A address mirroring, D and B；
Step 3, public network are synchronous to Intranet, specifically comprise the following steps:
Step 3.1 formats the data for needing synchronization；
Step 3.2, the ZIP file that formatted data are packaged into encryption；
The ZIP file that step 3.3, starting thread upload encryption with FTP connection type is deleted after uploading successfully to the address A
ZIP file；
Step 3.4, Intranet program starting thread, from the address C, are downloaded file and are saved in specific bit in a manner of FTP downloading
It sets；
Step 3.5, decompression thread monitor download location decompress file, identification file mark, and synchronized update is corresponding
