4 is a flowchart illustrating a data sharing method using a network file service processor according to the present invention.

Referring to FIG. 4, first, a user operates a terminal such as a mobile phone, a PDA, or a PC to connect to the first network file processor 11 through the Internet and request an access approval. Therefore, the first network file processor 11 receives a corresponding signal through the first and second Ethernet ports 116a and 116b, and the user receives the signal according to the TCP / IP (111c) protocol and the Netbios (111b) protocol. The connection request is confirmed and the connection request is connected to the source of the access approval request signal for file sharing (S11).

Therefore, the user operates the terminal again to request a directory list of the first hard disk 122, and the transmitted signal is transmitted to the first network file processor 11 through the first and second Ethernet ports 116a and 116b. Is received on. In this case, the first and second Ethernet ports 116a and 116b may be changed by the control of the Mac controller 115 so that any one of them may be received at the other side (S12).

In this case, the first bootcode includes a setting program of the second bootcode, and an administrator arbitrarily selects and sets a plurality of application programs. That is, as the first bootcode includes the setting program of the second bootcode, the administrator runs the corresponding program in the first bootcode and arbitrarily selects among the kernel and the application program to store the first bootcode in the first hard disk 122. It is set as the second boot code (S21).

When the first network file processor 11 receives a connection approval request signal from the user through the first and second Ethernet 151 ports 116b, the TCP / IP 111c and the netbios 111b ( Netbios) establishes the user's IP verification and route according to the protocol and maintains the connection with the user, thereby authorizing the user's connection (S22, S23).

Subsequently, when a directory list or a file and data request signal are applied from the user, the file sharing program 111a is driven to control the disk driver 111d to apply the control signal to the first host-disk interface 114. (S24)

Therefore, the first host-disk interface 114 converts data according to the protocol with the first disk device 12 and transmits the corresponding signal to the first disk device 12 (S25).

Then, when the directory list or data and file are transmitted from the first disk device 12, the directory list or data and file are received, converted into data conforming to the protocol of the first network file processor 11, and output. Therefore, the CPU 111 outputs it to the user through the first or second Ethernet ports 116a and 116b (S26).

Referring to FIG. 6, the PC 14 reads the control of the second network file processor 15 and the stored program and data of the second disk device 13 and outputs a request signal, and outputs the virtual Ethernet driver 141. Converts the data input and output from the PC 14 to match between the USB (not shown) side installed in the PC 14 and the Ethernet 151 side of the second network file processor 15. When the PC 14 or the external user connected to the Internet is connected, the second network file processor 15 is tunneled to the Internet protocol to extract disk interface data and send the data to the second disk device 13. Of the signals transmitted from the disk device 13, the disk interface data is extracted and tunneled into Internet packets to be transmitted to the PC 14 via the Ethernet 151.

In this case, the virtual Ethernet driver 141 is recognized as a logical separate network card sharing the Ethernet 151 card of the PC 14, and performs the task of tunneling the Internet-interface (IEEE1394) data, 14) The operating system supports the interface driver device service, and the PC 14 processes the second disk device 13 in the remote network via a USB (not shown) or a serial interface (not shown). It can be used like a device connected to.

In addition, in the second network file processor 15, the Ethernet 151 transmits and receives a signal with an external user connected through the PC 14 or the Internet, and the fixed / floating IP 152 protocol allows the connected user to move the IP. If you have it, report the location to the DDNS server on the web so that users can easily access and use it on the Internet using logic (url). The transmission protocol 153 (TCP) is a protocol for data transmission, and the protocol conversion unit 154 is configured such that the protocol between the Ethernet 151 and the interface side of the second disk device 13 included therein is identical. Convert the protocol.

In the second disk device 13, the second host-disk interface 131 is connected to the second network file processor 15, and the second disk controller 132 controls the second hard disk 133. The second hard disk 133 stores large files, data, and various kinds of information.

7 is a flowchart illustrating another embodiment of a data sharing method using a network file processor according to the present invention.

When a user operates a PC 14 connected to the second network file processor 15 via a network or the Internet, and inputs a connection approval request signal, the virtual Ethernet 151 driver 141 in the PC 14 receives a PC. The data is converted and output so as to match the protocol between the (14) side and the second network file processor 15.

Therefore, when the connection request signal is received from the PC 14, the second network file processor 15 checks the IP and the path of the PC 14 and approves the connection (S31).

When the directory listing request signal is received from the PC 14, the second network file processor 15 extracts the interface data of the second network file processor 15 from the signal and the second disk device 13 In step S32, the corresponding signal is outputted, and the data of the directory list received from the second disk device 13 is tunneled into an Internet packet (S32).

In addition, when the file and data request signals are received from the PC 14, the second network file processor 15 extracts the interface data of the second network file processor 15 from the corresponding signal to the second disk device ( 13) and tunnels the received file and data to an Internet packet and transmits it (S33).

If it is determined that the floating IP is determined, the microcontroller 155 transmits the user's IP to a dynamic domain name server (DDNS Server) through the Internet. Therefore, the dynamic domain name server transmits the received user's IP to another domain name server, thereby enabling the user to access the second network file processor using a general URL (S43).

The microcontroller 155 approves the user's connection (S44).

The microcontroller 155 extracts the interface data of the second network file processor 15 from the received signal and transmits the extracted data to the second disk device 13 (S52 and S53).

Therefore, the second host-disk interface 131 of the second disk device 13 converts the transmitted data according to the protocol between the second network file processor 15 side and the second disk device 13. The second disk controller 132 is applied. Therefore, the second disk controller 132 reads the directory list or data and files from the second hard disk 133 and transmits them through the second host-disk interface 131 according to the request signal. The controller 155 receives a directory list or data and files transmitted from the second disk device 13 (S54).

The microcontroller 155 tunnels the received data to an Internet packet and transmits the data to the PC 14 through the Ethernet 151. That is, the second network file processor 15 drives a server for a file service. The server monitors a specific port number of a TCP packet and performs an authentication process when a TCP handshake operation for the port number is completed. Interface (IEEE1394) starts a tunneling service for data transmission and reception (S55).

In this case, the authentication-related data may be performed by sending a TCP packet to an option item or a separate payload, or all functions related to upper layers may be performed using a function of an interface.
