The present invention relates to a data communication network and a service providing method. In particular, by connecting a user terminal and a backbone network through a wireless network clustering device, a plurality of users can be easily accessed without being affected by the terrain, features, installation and operation environment. A traffic distribution processing network system capable of accessing a network and enabling effective distributed processing of traffic when using data communication, and a method for providing a traffic distribution processing service using the same.

Conventionally used conventional networks utilize a multi-stage network approach. This conventional network configuration is shown by way of example in FIG.

1 is a block diagram showing a conventional network.

Referring to FIG. 1, a conventional network includes a router 1 that provides an optimal path between the Internet or another network, a web server 2 that is connected to the router 1 to provide an Internet service environment, a router, and a user. A second node (3, 4, 5) providing a data path between the terminals 10, a second node (3, 4, 5) connected to the first node (3, 4, 5) to provide data communication, including Internet communication, to the user ( 6, 7, 8, and 9) and a terminal 10 connected to the second node or the first node and connected to the Internet.

The first nodes 3, 4, and 5 refer to a terminal device or a branch that provides a data branch such as a digital subscriber line access multiplexer (DSLAM), a cable modem termination system (CMTS), and a HUB. DSLAM (5) is a multiplexing equipment for DSL access that collects data transmitted and received by the digital subscriber line (DSL) modem at the end and transmits it to a backbone network, that is, a device accessible to the Internet. In addition, CMTS is a device that enables users to communicate data by converting modem data transmitted and received by modem installed at the end of cable such as coaxial cable into Internet data packet.

The second nodes 6, 7, 8, and 9 are means for directly connecting the first nodes 3, 4, 5 and the user terminal 10 to the DSL modems 8, 9 and WLAN access points (APs). (7) and Cable Modem (6).

In a conventional network, an Internet service provider (hereinafter referred to as "ISP") provides a transmission line and installs and maintains a line immediately before a terminal, that is, the modems 6, 7, 8, and 9. And maintenance, and the user is generally operated in the form of paying the service fee to the ISP. Such a conventional network is judged to be a consistent and efficient form at first glance, but it is true that an ISP has a lot of burden due to the operation and management of a detailed network of an end.

First, the ISP manages a large-capacity, high-speed transmission path such as an optical communication network and a high-speed communication network from the backbone network to the first nodes 3, 4, and 5. The first communication line is connected to the main communication network, or is installed in a portion adjacent to the main communication line, so that the subsequent maintenance is relatively easy if only the huge cost required for initial installation is handled. As such, the first communication line is installed only to the first nodes 3, 4, and 5 installed in a part of city, county, and town unit areas as the first entrance of a large apartment complex. From the first node 3, 4, 5 to the user terminal 10 end or the second node is transmitted using a different transmission path and method than those used in the first communication network. That is, from the first nodes 3, 4, and 5, a relatively low-capacity, low-speed optical network and a cable network are installed as compared with the first communication network. The second communication network includes modems 6, 7, installed in user homes and offices. 8, 9). As such, when the multi-stage communication network is installed, the user connects his terminal to the modems 6, 7, 8, and 9 and uses the Internet, and provides the ISP with the cost of using a predetermined service.

On the other hand, the first communication network of the first and second communication networks maintained and managed by the ISP connects a specific location such as a telephone station at a telephone station and a city at a city. However, in the case of the second communication network, since the installation environment is very different from that of the first communication network, the installation, maintenance and repair of the second communication network are not easy.

In the case of the second communication network, since the user must be installed to the place where the user lives or lives, it is spread to the home or the office through the telephone pole or the underground track which is commonly seen in the surroundings. For example, since DSL lines mainly use telephone lines, in order to connect users with DSLAMs 5 installed in designated places such as telephone stations, a telephone line must be constructed to the connection area. Or it will be used in combination with the telephone line already established. In the case of using a cable, a cable network for cable broadcasting or a cable for data communication must be separately installed.

Since the conventional network has the features described above, it is very difficult to expand the subscriber network of the second communication network. That is, the conventional network has a disadvantage in that a new subscriber is generated or when a single subscriber uses multiple terminals, a new transmission path must be added or changed to be installed. In addition, one modem or one AP is connected to each dedicated line, and in the case of a modem, a limitation of an installation environment in which a terminal should be installed in an adjacent place where a modem is installed is also a problem. In addition, when a user using a leased line is moved, there is an inconvenience of removing the installed temporary road and installing a new leased line in the previous place.

In addition, the conventional network has a problem that cannot be used due to force majeure, even if the user wants to use a faster communication method because it must determine the installation or impossible according to the residential environment of the resident. In more detail, in order to provide a DSL-based leased line service, a subscriber using a leased line using a cable LAN method had to remove the existing cable leased line and construct a DSL line. In addition, by returning the modem used in the cable method to the ISP, the DSL modem is supplied and used, there is a problem that requires a huge cost and time due to the change of transmission path. Due to these problems, the conventional network method requires a great deal of time and effort for the ISP to install, maintain and maintain the second communication network.

Therefore, by making the user terminal and the backbone network irrelevant to the user use environment, a new network access method capable of efficiently and easily connecting the user terminal and the backbone network is urgently required.

Accordingly, the present invention is to solve the above problems, by configuring the communication network of the user terminal as a wireless network clustering device, connecting some of the network clustering device and the backbone network, affecting the terrain, features, installation and operation environment It is an object of the present invention to provide a traffic distribution processing network system and a traffic distribution processing method using the same, capable of effectively distributing traffic when using data communication.

Further, the present invention significantly reduces the number of first communication networks directly connected to the user terminal, and removes the wired network portion of the user terminal, thereby preventing traffic from being excessively spent on installation, maintenance, and maintenance. Another object of the present invention is to provide a processing network system and a traffic distribution processing method using the same.

To this end, the present invention is a network clustering device that is directly connected to the user terminal, a network clustering device for traffic distribution processing, a second communication network consisting of a network clustering device connected to the backbone network, and the second communication network is a backbone network It is another object of the present invention to provide a traffic distribution processing network system having a first communication network having a modem which allows a modem to be connected to a network, a first node having modems connected to and accessible to a backbone network, and a traffic distribution processing method using the same. do.

In addition, the present invention provides a traffic distribution processing network system capable of providing a connection between the first network clustering device or the second network clustering device and the user terminal and its operation method in order to increase the degree of freedom of operation of the user terminal and the second communication network and the same. Another object of the present invention is to provide a traffic distribution processing method.

In addition, the present invention uses a wireless communication method as a communication method for the traffic distribution processing of the second communication network, the wireless communication channel to the unlicensed frequency band to almost eliminate the influence of the installation environment, to present flexibility of the second network operation Another object of the present invention is to provide a traffic distribution processing network system enabling the use of a commercial licensed frequency band and a traffic distribution processing method using the same.

Lastly, the present invention allows the user to select whether to share the traffic distribution process or the network access service sharing of the network clustering device constituting the second communication network, and to autonomously select whether to participate in the traffic distribution process. Another object of the present invention is to provide a traffic distribution processing network system and a traffic distribution processing method using the same, so as to secure data stability.

In order to achieve the above object, a traffic distribution processing network system according to an embodiment of the present invention is established by an Internet service provider or an Internet user, and is connected to a first communication network providing a first node accessible to the Internet, and connected to a first node. A first network clustering device providing a second node for connection with the first communication network, the first network clustering device being connected via a wireless communication channel with the first network clustering device, the communication network with the first communication network or from adjacent network clustering devices; And a second communication network having at least one second network clustering device for sharing and distributing traffic of the network.

And a fourth step of determining a transmission path to a user terminal connected to the device and performing data communication that is a cause of communication traffic through the transmission path.

Other features and operations of the present invention in addition to the above objects will become apparent from the detailed description of the embodiments with reference to the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 8.

2 is a block diagram illustrating a traffic distribution processing network system according to an embodiment of the present invention.

2, a first communication network 32 connected with a backbone network 31 including a web server 21 or the Internet 20, and a second communication network connected with the first communication network 32 ( 34).

The first communication network is connected to the backbone network 31 to search for an optimal path, and provides a routing device 22 for providing a data traffic path between networks, and a first device 33 connected to the routing device 22. Is divided into the access device 33. The access device consists of a DSLAM 23, a CMTS 24, or a HUB 25. This access device 33 provides a first node for connection to the backbone network 31 to a corresponding device of the second communication network 34. In this case, as shown in FIG. 2, the HUB 25 may provide a connection between the network clustering device 28a and the user terminal 29a and the backbone network 31 directly without a second node. The first communication network 32 is configured by using a high-speed high-capacity dedicated line or an optical communication network such as E1, T1, T2, and T3.

The second communication network 34 is connected to the second node 35, which is constituted by the modems 26 and 27 and the first network clustering device 28, and the backbone network 31 is connected to the second node 35. It consists of a lower second communication network 36 to be connected.

The second node 35 is a modem 26, 27 connected with the first node 33 of the first communication network 32 and the first network clustering device 28b, 28c connected with the modem 26, 27. It consists of. Here, the first network clustering device 28a that can be directly connected to the hub 25 is also included in the second node 35.

The lower second communication network 36 shares the traffic by wireless communication with the first network clustering device 28 or the second second network 33 connects to the backbone network 31 through the first and second nodes 33 and 35. It consists of a user terminal 29 connecting to the first and second nodes 33, 35 via the network clustering device 30, the first network clustering device 28, or the second network clustering device 30. The second network clustering device 30 allows network connection of the wired terminal device and the wireless terminal device connected to the corresponding device. Separately, the second network clustering device 30 provides a service for network connection to wired / wireless terminal devices located in the second communication network 36 by providing a channel for communication with each other.

An embodiment of the present invention of FIG. 2 will be described in more detail with reference to FIG. 3.

3 illustrates the embodiment of FIG. 2 in more detail and illustrates a second communication network in more detail.

Referring to FIG. 3, in the traffic sharing processing network system according to an exemplary embodiment of the present invention, a dedicated line is not connected to each user terminal. As shown in FIG. 3, a modem 40 connected to the first communication network 32 is connected to some first network clustering device 41. That is, the network clustering device 41 connected to the modem 41 connected to the first communication network 32 becomes the first network clustering device 41. The distance that can communicate with the first network clustering device 41, or between the plurality of second network clustering devices 42, 43 and the plurality of users between the first network clustering device 41a and the first network clustering device 41b. Terminal 44 is located. That is, the group that can access the backbone network 31 only by using the first network clustering device 41 among the network clustering devices and the user terminal 44 becomes the lower second communication network 42, and the lower second communication network ( 42 is configured by the second network clustering devices 42 and 43 and the user terminals. At this time, even if the first network clustering device 41b exceeds the traffic capacity of the first network clustering device 41b, when the neighboring first network clustering device 41a needs to request sharing of traffic, The first network clustering device 41b may also be included in the lower second communication network 42. In addition, the network clustering devices 42 and 43 included in the lower second communication network 42 also serve as the first network clustering device 41b when they can be connected to the first node 33 such as the modem 40. Will be performed.

The network clustering devices 41, 42, and 43 perform respective communication over the air. In other words, each of the network clustering devices 41, 42, and 43 has a radius of circular or side-lobed radiation pattern having a predetermined radius according to the omni-directional and directed characteristics of a given output and a used antenna in an ideal environment. It has a limited communication distance. Each network clustering device 41, 42, 43 may form a redundant communication path between the network clustering devices 41, 42, 43 with overlapping communication distances.

In more detail, for example, in the case of the user terminal 44b, the devices of the modems 26 and 27 that can connect to the first node 33 and the second node 35 are not connected. At this time, when the user terminal 44b requests access to the backbone network 31, the second network clustering device 42b searches for an adjacent second network clustering device 43b. When the second network clustering device 43b is found as a result of the search, a communication channel is formed between the second network clustering device 42b connected to the user terminal 44b and the discovered second network clustering device 43b. In addition, the second network clustering device 43b for distributed processing goes through a process of searching for and connecting the network clustering device for the connection with the first or second nodes 33 and 35. In this process, each network clustering device 42 or 43 determines the amount of traffic concentrated on each network clustering device 42 or 43, or if the user allows traffic sharing to avoid the network clustering device where the traffic is concentrated. It is determined whether or not the best route to explore. That is, the path through which the user terminal 44b can access the backbone network 31 is CL1_1 (41a)-CL2_1 (42a)-CL2_2 (43b)-CL2_4 (42b), CL1_1 (41a)-CL2_3 (43c)- CL2_2 (43b)-CL2_4 (42b), CL1_1 (41a)-CL2_1 (42a)-CL2_5 (43a)-CL2_2 (43b)-CL2_4 (42b), CL1_2 (41b)-CL2_2 (43b)-CL2_4 (42b) Various paths can be selected, for example. That is, each user terminal can be connected to the backbone network 31 without being provided with the modem 41 and the dedicated line. As a result, the present invention enables a user to use data communication through the backbone network 31 by connecting to various types of networks regardless of one communication method such as DSL and cable.

Such network clustering devices 41, 42, and 43 may be licensed to unlicensed frequency bands such as Industrial, Scientific, and Medical (ISM) or Unlicensed National Information Infrastructure (U-NII) frequency bands, CDMs, and GMSs. Communication may be performed using a mobile communication frequency band including GSM) and portable Internet (WiBro or WiMax).

Although the ISM and U-NII frequency bands can be used without prior permission to provide separate network services, they are limited to relatively short distance communication because they allow only weak radio emission. From other users using the same frequency or from the surrounding environment, mediation or understanding of limited channel usage between users is required in advance due to the deepening of interference caused by over-access of the same channel. However, the connection with the network connection device or the terminal device that can communicate with the network clustering device can be made without prior approval of the radio regulatory authority, which provides the advantage of quick and easy network installation and service provision. In addition, it is possible to implement using a short-range wireless communication frequency band, or a mobile communication frequency band used for a wireless LAN frequency band, such as 802.11, wireless ATM frequency band, Bluetooth, Zigbee. However, for the traffic sharing, a large amount of data can be processed at high speed, and any frequency band can be used as long-range wireless communication can be used. Due to the characteristics of the communication frequency band and the communication frequency, the network clustering devices 41, 42, and 43 may distribute a plurality of terminals such as an access point (AP) used in a wireless LAN. That is, it is possible to connect several terminals to one network clustering device 41, 42, 43 to access the backbone network 31.

In addition, the traffic distribution processing network system according to an embodiment of the present invention can select and use the traffic distribution of the network clustering device according to the user's intention to use the service or the processing capacity of the traffic. In addition, when a user who owns each network clustering device transmits personal credit information through his or her network clustering device, in order to prevent the possibility of hacking, the user stops distributed processing of traffic from outside. The transmission path may be set to the shortest distance and the highest priority traffic so that the traffic can be transmitted on the shortest path.

As can be foreseen through FIGS. 2 and 3, the traffic distribution network system of the present invention is provided in the form of owning and using each network clustering device by an individual user. Of course, it is also possible to secure a transmission path by arranging a plurality of network clustering devices owned by one or a group of users at a designated location. Such a network clustering apparatus may be used for the purpose of connecting each terminal 44 to the backbone network 31, and may be used for the purpose of dedicating the sharing of traffic. It is also possible to operate by merging them. In addition, a user configures the second communication network 34 through the plurality of second network clustering devices 43 and one or more second nodes 35, and provides a network service to other users to receive charges for using the service. Some form of service is also available.

If IPv6 is used to implement a system using such a network clustering device, it is possible to assign and use respective IP addresses to all of the subscriber terminals, but under the current IPv4, an IP address shortage phenomenon becomes more prominent. To this end, the user-owned network clustering device should create a user classification signal for distinguishing each user terminal or network clustering device such as an IP router (NAT) and include it in the transmission data. In this case, the first network clustering device 41 connected to the second node 35 and the network clustering device 42 connected to the user terminal may proceed with the creation and inclusion of such a user distinguished signal. The process of generating and including a user identification signal may be performed in a network clustering device existing on a path through which corresponding data is transmitted. In addition, even when a plurality of user terminals are connected to one network clustering device, it is possible to distinguish the user terminals using the user identification signal.

4 briefly illustrates a configuration of a network clustering apparatus according to an embodiment of the present invention.

Referring to FIG. 4, the network clustering apparatus according to the embodiment of the present invention includes at least one RF transceiver 50, a modulator 51, a controller 52, a memory 53, a relay processor 54, The beacon processing part 55, the routing part 56, the communication processing part 57, and the wired I / O part 58 are provided.

The RF transceiver 50 forms a communication channel with an adjacent network clustering device to provide a communication path in order to transmit and receive a radio signal for communication between the network clustering devices. In order to be able to use heterogeneous communication methods simultaneously, different RF modules may be provided according to communication methods.

The modulator 51 provides a modulation and demodulation function between the RF signal and the baseband signal between the at least one RF transmitter / receiver 50 and the controller 52.

The control unit 52 transmits and receives a wireless message with a communication device on a network, routes a wireless message between the network clustering device on a network, and relays the wireless message, and the RF transceiver 50 and the modulation / demodulation unit 51. Control unit 54, beacon processing unit 55, routing unit 56, communication processing unit 57, and the like.

The memory unit 53 provides a memory space required for each component including the control unit 52 to proceed with the process, and stores driving programs and data for controlling them.

The relay processing unit 54, together with the routing unit 56, controls the data passing through the network clustering device under the control of the control unit 52, so that traffic can be distributed.

The beacon processing unit 55 identifies other network clustering devices and user terminals existing on the network, and generates and interprets a beacon signal for synchronization between the network clustering device and the user terminals.

The routing unit 56 performs routing and exchange of routing / forwarding information between adjacent network clustering devices under the control of the control unit 52.

The communication processor 57 transmits data provided through the wired I / O unit 58 to the RF transceiver 50, and transmits data received from the RF transceiver 50 from the wired I / O unit 58. Relays data between wired and wireless for processing.

The wired I / O unit 58 is an interface unit for connecting a network clustering device and a user terminal by wire, and provides an interface such as an Ethernet port RJ-45. In addition, it can be equipped with various interfaces such as USB or IEEE 1394 (FireWire), and a flash memory slot.

5 illustrates a traffic distribution processing method using a traffic distribution processing network system according to an embodiment of the present invention.

Referring to FIG. 5, the traffic distribution processing method according to the present invention includes a first step (S1) in which a first communication network formed by an Internet service provider or an Internet user and a first network clustering device are connected to maintain a communication network, and a first A second step (S2) in which communication traffic occurs in a communication network or a second communication network; a third step (S3) in which the network clustering device in which the communication traffic has occurred searches for a neighboring network clustering device; and a third step A fourth step S4 of determining a transmission path to a user terminal connected to the first network clustering device or the second network clustering device, and a fifth step of performing data communication as a cause of communication traffic through the transmission path ( S5).

In a first step S1, a first communication network and a first node are installed by an ISP or an internet user. In addition, a second node is installed in a user who operates the first network clustering device, and the first node and the second node are connected. In this case, the first communication network is preferably provided with a high-speed high-capacity dedicated line, a relatively low-speed low-capacity dedicated line is installed between the first node and the second node. Then, the user connects the second node and the first network clustering device, and other users who do not connect with the second node join the second communication network using the second network clustering device and their respective user terminals. . Here, the second communication network includes at least one modem, at least one first network clustering device connecting to the modem, and a second network clustering device and a first network clustering device or second connecting to the backbone network through the first network clustering devices. It is configured to include a user terminal connected to the network clustering device.

In the second step S2, traffic by communication is generated. For example, traffic from a user terminal connected to the first network clustering device to a user terminal or a backbone network existing in the second communication network may occur, and traffic may occur between the second communication network and the backbone network.

In the third step S3, the transmission path for communication is searched according to traffic generation. For example, when traffic is generated from a second network clustering device belonging to the second communication network and a user terminal connected thereto, the second network clustering device connected to the user terminal uses an adjacent second network clustering device or a second node for communication. The first network clustering device is formed. Alternatively, a connection may be attempted from a backbone network to a user terminal in a second communication network such as a remote control. In this case, the first network clustering device searches for the second network clustering device in the second communication network to transmit data to the destination user terminal.

In the fourth step S4, a transmission path to the second network clustering device, the first network clustering device, and the modem is secured according to the search result, and data communication is performed through the transmission path secured in the fifth step S5. .

The first step S1 includes a first substep of transmitting data from the user terminal to a second network clustering device connected to the user terminal when the traffic is generated from the user terminal in the second communication network. Alternatively, when data is transmitted from the first communication network via the second node, the method further includes a second substep of transmitting data from the modem to the first network clustering device.

FIG. 6 illustrates the second step of FIG. 5 in more detail.

Referring to FIG. 6, a second step of generating traffic includes third substeps S21 and S22 of generating data causing traffic. As described above, the data may be generated from a user terminal connected with the first network clustering device or the second network clustering device, or may be generated from the backbone network and transferred to the destination. The data transfer process is not terminated by one transmission, but transmission and reception are repeatedly performed several times. One of the important things in this process is to distinguish between destination and source. In other words, the source of the data is the source from the point of view of the receiver, and the destination of the data is the destination from the point of view of the transmitter. Under the new IPv6 scheme, it is possible to assign and use each IP address to a large number of terminal devices. However, under the current IPv4, it is difficult to give an IP address to each terminal in reality.

To this end, in the third sub-step, a user separation signal is created by the network clustering apparatus that first receives the data (S22). Then, the created user identification signal is included in the data to be transmitted (S23), and the data including the user identification signal is transmitted to the destination (S24). For example, the recognition in the first communication network or the backbone network may recognize the second communication network as one IP address. However, the first network clustering device for transmitting data or the second network clustering device connected to the user terminal may be given a virtual IP address in the second communication network. In this case, the assigned virtual IP address becomes a user identification signal. The user identification signal may be assigned in advance at the time of constructing the second communication network, but may be arbitrarily assigned at the time of use.

FIG. 7 is a flowchart illustrating in more detail the third and fourth steps of FIG. 5.

Referring to FIG. 7, in the embodiment of the present invention, when data is generated, the data is transmitted through an adjacent network clustering device. To this end, the network clustering device provided with data must select a network clustering device to be used as a path for communication among a plurality of network clustering devices existing in the second communication network.

That is, the network clustering device receiving the data performs a fifth sub-step of searching for an adjacent network clustering device capable of transmitting data (S31). According to the discovery of the neighboring network clustering device, it is determined whether the neighboring network clustering device is found, and if no neighboring network clustering device is found, the neighboring network clustering device is searched until the neighboring network clustering device is found or the search is terminated under a predetermined condition (S32). ).

On the other hand, if the neighboring network clustering device is found, it is determined whether the number of neighboring network clustering devices is one or more (S33). If it is determined that the number of the neighboring network clustering devices found is one, the sixth sub-step of determining whether to allow sharing and relaying of traffic is performed (S34). When the sharing of traffic is allowed, the discovered neighbor network clustering device is secured as a data transmission path.

8 is a flowchart illustrating a method for securing a transmission path when two or more adjacent network clustering devices are found in FIG. 7.

Referring to FIG. 8, when there are two or more neighboring network clustering devices in FIG. 7, the method of using both is not easy. Therefore, one of the neighboring network clustering devices must be secured as a transmission path.

In this case, the searched network clustering device proceeds to the first couple step of determining the connection priority. That is, the network clustering device which does not allow traffic sharing and relaying among the two or more network clustering devices is excluded from the target (S41). The network clustering device in which the current traffic is saturated among the remaining search targets is excluded (S42).
