Smart Matching Networking System Using Router

The present invention relates to a smart networking system using a router, and more particularly, a target engaged with the router remotely by performing the port connection control automatically between the viewer terminal externally and the target terminal engaged with the remote router. The present invention relates to a smart matching networking system using a router capable of freely connecting to a terminal.

In general, in order to access other computers through a router from outside, they are connected through a port, which is a virtual logical connection structure for direct connection without exchanging files or temporary storage when exchanging information between programs. Representative ports for the connection are TCP and UDP ports.

Here, in order to remotely access another computer from the outside, it is possible to remotely access another computer bited by the router through the port opening through a port forwarding process between the external, the router, the router and the other computer.

However, since the conventional port forwarding process can be set through a very complicated process of directly inputting IP information or port information, there is a problem that setting is very difficult.

For users who are not familiar with computer details, it is not easy to check the IP information of a computer terminal. Therefore, performing port forwarding is recognized as a very difficult process.

In addition, in the conventional networking system, the same port may be allocated between the router and the target terminal engaged with the router, but since only one viewer terminal may be connected to the same port, the other viewer terminal may be separately connected to the port forwarding. There is a very troublesome connection because it needs to connect after processing port mapping.

An object of the present invention is to solve the problems as described above is that the router performs a port connection control between the viewer terminal in the outside and the target terminal engaged with the remote router, the target to be engaged with the router from the remote The present invention provides a smart matching networking system using a router capable of freely connecting to a terminal.

In order to achieve the above object, the smart matching networking system using the router according to the present invention may be configured to display the router access information of the specific target terminal in response to a request for access to a specific target terminal of a viewer terminal of a remote site through an external Internet. And matching port information to a management server provided as a viewer terminal and a viewer terminal connected with the router access information, and controlling a connection between the viewer terminal and the target terminal through the port information.

The management server provides a viewer application to the viewer terminal, and a router providing information in which a target terminal is engaged with a program providing unit providing an agent program to the target terminal and a request for access to a specific target terminal from the viewer terminal. It characterized in that it comprises a router connection information providing unit for extracting and providing.

The router access information providing unit maps the client identification information to store and manage access information (including target terminal IP and target terminal MAC address) of the target terminal and router access information (including router IP information) that the target terminal has inherited. Smart matching networking system using a router.

In addition, when there is a request for port information for a specific target terminal from a viewer terminal of a remote place through an external Internet, the router extracts port information accessible to a specific target terminal connected to the router and provides the viewer terminal to the viewer terminal and the target. It characterized in that it comprises a port matching module for automatically controlling the connection of the terminal.

The port matching unit extracts and provides port information according to a request of a viewer terminal and the viewer terminal and a target when the viewer terminal requests access to a port information specific target terminal provided from the port information extraction module. Characterized in that it comprises a connection management module for connecting the terminal.

In addition, when the viewer terminal requests port information while the viewer terminal transmits the access information of a specific target terminal, the port information extracting module analyzes the actual port information of the specific target terminal and connects to the port using the actual port information. Providing information to the viewer terminal, extracting available virtual port information and providing the same to the viewer terminal when the connection is not possible with the actual port information, and storing and managing the virtual port information and the actual port information by mapping. do.

The access management module connects the viewer terminal with the specific target terminal when the access request is made from the viewer terminal using the actual port information of the specific target terminal, and when the access request is made with the virtual port information, the access management module attaches to the virtual port information. The viewer terminal and the specific target terminal are connected by mapped actual port information.

In the smart networking system using a router according to the present invention, the router automatically performs a port connection control between an external viewer terminal and a target terminal engaged with a remote router, regardless of whether an external port is used or not.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a system configuration diagram schematically showing a smart matching networking system according to a preferred embodiment of the present invention, Figure 2 is a detailed block diagram of FIG.

1 and 2, the smart matching networking system according to the present invention includes a viewer terminal 40, a target terminal 10, a router 20, a management server 30, and a viewer terminal 40. Can be.

Here, the target terminal 10 refers to a terminal connected to the router which the client designates as a target to be accessed by the viewer terminal of the remote location, and the viewer terminal 40 is connected to the remote terminal through the external internet to access the target terminal. Means the terminal located in.

The target terminal 10 and the viewer terminal 40 may include all terminals capable of internet access as well as computer terminals such as PCs and laptops.

In particular, the viewer terminal 40 is connected to the target terminal 10 in the case of a portable smart phone, a mobile carrier-based portable Internet terminal capable of accessing the Internet, and the like, using the process of the target terminal 10 as it is, as the viewer terminal 40. Since the same effect can be obtained by executing the function of the utility is very large.

The management server 30 is responsible for providing an agent program and a viewer application to the target terminal 10 and the viewer terminal 40, respectively, and engaging the target terminal 10 at the request of the viewer terminal 40. It is responsible for providing router IP information.

More specifically, the management server 30 when the target terminal is requested to access the target terminal through the program terminal 310 and the viewer terminal for providing an agent program and a viewer application to the target terminal and the viewer terminal; It may be configured to include a router access information providing unit 320 for providing the interlocking router access information.

The agent program installed in the target terminal 10 is a program for sharing IP information and port information of a target terminal in synchronization with a router supporting smart matching networking according to the present invention.

The viewer application is a program that can remotely control the target terminal by accessing the target terminal designated by the viewer terminal.

After all, the agent program and the viewer application are synchronized with the target terminal when a port is connected between the viewer terminal 40 and the target terminal 10 so that the remote viewer terminal 40 can use a program or file stored in the target terminal. It is a link program that can.

As described above, in order for the viewer terminal to remotely control various functions of the target terminal (for example, executing a video stored in the target terminal) through the viewer application of the viewer terminal and the agent program of the target terminal, the connection between the viewer terminal and the target terminal is established. If necessary, the router 20 is responsible for controlling the connection between the viewer terminal and the target terminal as described above.

To this end, the router 20 is configured to include a port matching unit 210 to control the port connection between the viewer terminal and the target terminal.

The port matching unit 210 is responsible for automatically controlling the port connection between the external viewer terminal and the router and the port forwarding connection between the router and the target terminal.

More specifically, the port matching unit 210 provides a port information extraction module 211 and the provided port that provide port information accessible to the viewer terminal when the viewer terminal via the external Internet requests access to a specific target terminal engaged with the router. It may be configured to include a connection management module 212 for connecting the connection between the viewer terminal and the specific target terminal with the information.

A more specific connection method will be described in detail later in the smart matching networking method.

Hereinafter, a smart matching networking method according to the present invention will be described.

First, an agent program, which is a software program, is installed on the target terminal, and access information is obtained (S110).

More specifically, when the setting application 110 is installed and activated, the target terminal extracts router IP information about the shared router, and extracts IP address and MAC address information of the target terminal to obtain access information. The agent program may be implemented by a client directly inputting router IP information, but may be configured to automatically extract IP information stored in the router for convenience of setting.

When the access information is obtained as described above, the agent program accesses the management server and provides an interface for setting identification information of the client.

The client sets identification information through the interface and transmits the obtained access information to the management server (S120).

Subsequently, the router access information providing unit of the management server registers the access information table in which the access information is mapped to the identification information in a database as shown in Table 1 below (S130).

Table 1

Identification Information		Router Connection Information	Target terminal connection information
ID	password	Router IP	Target terminal IP	MAC address
ABC	****	211.111.XXX.XXX	192.168.XXX.XXX	xx-xx-xx-xx-xx-xx

Through this, if only the identification information (ID, password) of the client can be remotely received, the access information and the router access information of the target terminal can be provided.

If the access information of the router or the target terminal is changed later, for example, the IP address is changed, the changed information may be transmitted to the management server to update the access information.

Subsequently, the viewer application installs a viewer application on the viewer terminal 40 that provides an interface for remotely accessing the target terminal.

First, the viewer terminal activates the viewer application, logs in to the management server (enter client identification information) through the viewer application, and requests the router access information of the target terminal.

When the connection to the target terminal 10 is requested as described above, the router access information providing unit 320 extracts the access information of the router 20 which the target terminal is inherited from the access information table and the viewer terminal 40. To transmit (S150).

The viewer application of the viewer terminal requests port information for accessing the target terminal designated by the router IP through the transmitted router access information (S160).

The port matching unit 210 of the router analyzes the port connection state of the target terminal engaged with the router according to the request of the viewer terminal and automatically performs port matching to transmit the extracted port information to the viewer terminal (S170).

More specifically, for example, the IP information of the router is "111.111.XXX.XXX", the access information of the target terminal (IP information is 192.168.XXX.XXX, and the MAC address is XX-XX-XX-XX-XX- XX) is assumed.

When the viewer terminal requests access while transmitting the access information of the target terminal through IP information of the router, the port information extracting module 211 of the port matching unit extracts the port information by analyzing the port information of the target terminal. )

Currently, when the port information of the target terminal is "1000", the port information extraction module may provide the port information "1000" of the target terminal to the viewer terminal, but the current port information "1000" is being used inside the router. Cannot provide access to the target terminal even if the port information " 1000 " is provided to the viewer terminal.

Because the same port can be shared in the internal network between the router and the target terminal engaged with it, the connection itself is impossible because the same port cannot be shared between the router and the external Internet.

Therefore, the port information extraction module 211 extracts the used virtual port information, for example, "1001", rather than the port information "1000" that can be connected to the target terminal, and transmits the extracted port information to the viewer terminal (S190).

In this case, the actual port information ("1000") and the provided virtual port information ("1001") are mapped to a port table for storage management.

Then, the viewer terminal 40 requests the connection with the target terminal with the virtual port information "1001" (S200), and the connection management module 212 of the port matching unit searches the port table to search the virtual port information (" 1001 ") and the actual port information (" 1000 ") mapped to the extracted terminal and the target terminal (" 1000 ") connected to connect the viewer terminal (S210).

Thus, the viewer terminal can be remotely connected to the target terminal and can freely execute a desired function or process.

In particular, the agent program of the target terminal 10 may play a role of streaming the video content when the viewer terminal 40 selects the video content stored in the target terminal. The video is played just as it does.

Although the detailed description of the present invention described above has been described with reference to the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, and those skilled in the art will appreciate It will be understood that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention.
