The proxy server includes a transmission module, a compression module, a decompression module and a connection module. The transmission module is for transmitting data between client end computer and FTP server. The compression module is for compressing data to be transferred to client end computer. The decompression module is in use for decompressing data to be transferred to FTP server. The connection module is in use for connecting with FTP server based on request sent from user. The invention increases speed for transferring files, and raises safety for transferring files.
Description
[technical field]
The present invention relates to a kind of document transmission system and method, particularly relate to a kind of file transfer agent system and method.
[background technology]
FTP is the basis of Internet file transfer, and it is made up of a series of specification files, is used for data is sent to another computer on the consolidated network from a computer on the network.
The same with most of Internet services, FTP also is a client/server system.The user is connected to the server program that moves by a client program-FTP on remote computer.The user gives an order to server program by client program, and server program is carried out the order that the user sent.Such as the user sends an order, requires server to copy to the portion that the user transmits certain file, and server can respond this order, specified file is delivered on user's the machine.The client program representative of consumer receives this file, and it is left in the User Catalog.To the computer of oneself, be referred to as " downloading (Download) " data from remote computer copy data.If data is copied on the remote computer, then be referred to as " uploading (Upload) " data from own computer.
Acting server is the server that signaling transfer point is provided on the net, be exactly the agency network user reach the network information.Vivid says that it is the terminal of the network information.
File transfer technology develops comparative maturity at present, in disclosed No. 20030208564 application case on November 6th, 2003, this application case name is called " information paper transmission control equipment (Data File Transfer Controlling Device) " as United States Patent (USP) trademark office.This application case provides a kind of information paper transmission technology.This technology discloses: send the Request signal to ftp server by ftp client, ftp server transmits needed data to ftp client.Simultaneously, this application case provides a data transmitting control with the transmission of control data between ftp client and ftp server.This data transmitting control provides the interim storage of a storage area pending data.Because this ftp client directly is connected with ftp server, the deficiency of this application case existence has: access speed is not high, poor stability and resource overhead are big.Realize transfer of data between client and the ftp server and the present invention acts on behalf of server by one, fetch the needed data of client by acting server.And, acting server has very big memory space, the data storage that it constantly will newly be obtained is to the memory of its this machine, when the visit identical information, directly read by buffer area, thereby can improve access speed, the present invention simultaneously also has the function of data compression, and the transmission quantity that can reduce data reaches the effect that improves transmission speed.And all users visit ftp server by acting server, can the limiting access authority, come data transmission by acting server, and also can protection be arranged to the safety of ftp server.
[summary of the invention]
Main purpose of the present invention is to provide a kind of file transfer agent system and method, and it can receive and the transmission data, and has the function of data compression.
File transfer agent of the present invention system comprises acts on behalf of server, a plurality of client computer and a ftp server.Wherein this acting server comprises a transport module, a compression module, a decompression module and a link block.Transport module is used for client computer and ftp server data transmission.Compression module, the data that is used for transferring to client computer is compressed processing.Decompression module, the data that is used for transferring to ftp server is carried out decompression.Link block is used to connect ftp server, if ftp server is normal, then can form the transmission of data between ftp server and acting server, if ftp server is undesired, and then connection failure.
The present invention also provides a kind of material upload method of file transfer agent.The method includes the steps of: (a) client computer compresses processing to data; (b) this packed data is transferred to acting server; (c) with this compression data carry out decompression; (d) request according to client computer connects ftp server; (e) and by network is monitored judge whether ftp server is normal; (f) if ftp server is normal, then will be the transfer of data of decompression to ftp server.
The present invention also provides a kind of data method for down loading of file transfer agent.The method includes the steps of: (a) request according to client computer connects ftp server; (b) and by network is monitored judge whether ftp server is normal; (c) if ftp server is normal, then download data from ftp server; (d) data is compressed processing; (e) this packed data is transferred to client computer; (f) client computer with this compression data carry out decompression.
Utilize the present invention, can improve file transfer speed, and improve security of File Transfer.
