UTP Cat.5 cable is a local area network (LAN) cable for short-range data communications. Because Ethernet transmission technology can transmit two-way 100Mbps speeds with only 2 pairs of cable per subscriber, high-speed Internet service providers can use a certain percentage of UTP depending on the number of households in the building. The service is provided by receiving and laying cables horizontally.

On the other hand, with the recent increase in high-quality IPTV channels, 3DTV activation, and increased file sharing traffic such as high-capacity Web hard / P2P, data transmission environment is required to be faster than the existing 100Mbps high-speed Internet.

However, this requires 4Pair UTP Cat.5 or higher cable per subscriber, so the UTP cable already installed by many high-speed Internet providers for the 100Mbps high-speed Internet service needs to be replaced or expanded with 4Pair's cable.

In the high speed data transmission system according to the present invention using a cable of the type shown in FIG. 1, prior to data transmission through the cable 100, the link transmission speed through the cable 100 is determined.

That is, at least one of the terminal repeater 200 and the aggregation relay 300 may be a data transmission speed and a cable 100 supported by at least one of the terminal repeater 200 and the aggregation relay 300. The link transmission speed through the cable 100 is determined based on the number of transmission paths provided in the circuit.

The maximum link transmission rate that can be transmitted can be determined.

In this case, the terminal relay apparatus 200 or the aggregation relay apparatus 300 that determines the link transmission speed may recognize the data transmission speed of the counterpart device through basic information sharing with the counterpart device connected through the cable 100. In addition, the data transmission speed of the counterpart device may be recognized through various methods.

The end relay device 200 transmits the received data corresponding to the at least one terminal device 10 connected through wire or wirelessly through the cable 100 to correspond to a predetermined link transmission speed.

In more detail, the terminal relay apparatus 200 may include a coding scheme corresponding to a link transmission speed that predetermines the received data corresponding to at least one terminal apparatus 10 connected through wire or wireless connection (eg, 2D-). Coding is performed based on PAM5), and the coded data can be simultaneously transmitted through each transmission path provided in the cable 100.

Accordingly, the aggregation relay 300 collects data transmitted through the cable 100 from at least one terminal repeater 200 and relays the data to an external network (for example, the Internet).

In more detail, when the aggregation relay device 300 receives data simultaneously transmitted through each transmission path of the cable 100 from the terminal relay device 200, that is, data corresponding to at least one terminal device 10. In addition, the data may be decoded based on a coding scheme (eg, 2D-PAM5) corresponding to a predetermined link transmission rate, and the decoded data may be relayed to an external network (eg, the Internet).

In this case, the data classification and relaying method in which the concentrating relay 300 collects data corresponding to a plurality of end relays 200 and relays the data to an external network (for example, the Internet), corresponds to a conventional method. Omit it.

Meanwhile, a process of downlinking data to terminal devices 10 of subscribers located in a building will be described below.

When the data corresponding to the terminal device 10 is received from the external network (for example, the Internet) to be transmitted to a specific terminal device 10 from the external network, the aggregation relay device 300 may correspond to the link transmission speed determined in advance. Transmission through the cable (100).

In more detail, the aggregation relay apparatus 300 performs a coding process based on a coding scheme (eg, 2D-PAM5) corresponding to a link transmission rate previously determined for data received corresponding to the terminal apparatus 10, The coded data may be simultaneously transmitted to a specific terminal relay apparatus 200 connected to the corresponding terminal device 10 through each transmission path provided in the cable 100.

In this case, the data classification and relaying method in which the concentrating relay 300 collects data corresponding to a plurality of end relays 200 and relays the data to an external network (for example, the Internet), corresponds to a conventional method. Omit it.

Accordingly, the terminal relay device 200 transmits / relays data transmitted from the aggregation relay device 300 through the cable 100 to the corresponding terminal device 100.

In more detail, when the terminal relay device 200 receives data simultaneously transmitted through the respective transmission paths of the cable 100 from the aggregation relay device 300, that is, data corresponding to the specific terminal device 10, the terminal relay device 200 receives the data. The data may be decoded based on a coding scheme (eg, 2D-PAM5) corresponding to a predetermined link transmission rate, and the decoded data may be transmitted by wire or wirelessly to the corresponding terminal device 100.

As described above, the high-speed data transmission system according to the present invention, the terminal relay device 200 and the aggregation relay device 300 is connected through a cable (100: 2Pair UTP CAT. 5) for ensuring 100Mbps already installed in the existing ) Automatically determines the maximum link transmission rate through the cable 100 based on the data transmission rate supported by the mutual device and the number of transmission paths provided in the cable 100, and corresponds to the determined link transmission rate. (E.g., 2D-PAM5), data is coded and transmitted simultaneously through each transmission path of the cable 100 in a full-duplex transmission method, thereby replacing the existing cable (100: 2Pair UTP CAT. 5) for 100Mbps guarantee. It can provide high speeds up to 500Mbps without the need for expansion.

Hereinafter, the configuration of the data relay device according to the present invention will be described in more detail with reference to FIGS. 2 and 3.

First, referring to FIG. 2, a data relay as the termination relay 200 will be described.

The data relay 200 according to the present invention is connected to one end of the cable 100 having a data transmission and reception unit 240 for transmitting and receiving data from the outside, and at least one transmission path formed in a pair, the data relay device Based on the data transmission rate supported by at least one of the other relay connected to the other end of the 200 and the cable 100, that is, the aggregation relay 300, and the number of the transmission paths provided in the cable 100 The transmission control unit determines the link transmission speed through the cable 100, and transmits the data received through the data transmission and reception unit 240 to the aggregation relay device 300 through the cable 100 to correspond to the determined link transmission speed. And 210.

In addition, the data relay 200 according to the present invention may further include a switching unit 230 and a traffic control unit 220.

The data transmission and reception unit 240 may include a communication module for transmitting and receiving data from the outside.

Accordingly, the data transmission / reception unit 240 may receive data for transmission to an external network (for example, the Internet) from at least one terminal device 10 that is wired or wirelessly connected, or to an external network (for example, the Internet). Data corresponding to the specific terminal device 10 relayed / transmitted through the aggregation relay device 300 may be transmitted to the specific terminal device 10 via wire or wirelessly.

The switching unit 230 performs a switching operation for data uplink transmission and downlink transmission between the data transmission / reception unit 240 and the transmission control unit 210.

That is, the switching unit 230 performs a switching operation to upwardly transmit data uplinked from the at least one terminal device 10 to the transmission control unit 210 through the data transmission and reception unit 240, and in the transmission control unit 210. In order to transmit the provided data to the at least one terminal device 10 through the data transmitter / receiver 240, a switching operation is performed to transmit the data to the data receiver 240.

The traffic conditioner 220 matches the data transfer according to the operation speed between the transmission controller 240 and the switching unit 230 according to the link transmission speed determined by the transmission controller 240.

In more detail, when the determined link transmission rate is determined as a specific link transmission rate at which a mismatch between the operation speed of the transmission control unit 240 and the operation speed of the switching unit 230 occurs, the traffic adjusting unit 220 transmits the transmission link. Based on the operation speed of the control unit 240 and the switching unit 230, at least one of performing buffering or changing the clock speed of data transmitted between the transmission control unit 240 and the switching unit 230 is performed to transfer data. Can match.

For example, since the transmission control unit 240, which will be described later, automatically determines the link transmission speed through the cable 100 automatically, the transmission control unit for transmitting / processing data to correspond to the determined link transmission speed (for example, 500 Mbps) ( Mismatch may occur between an operating speed of 240 (for example, 500 Mbps) and an operating speed of the switching unit 230 for switching up and down for data transmission (for example, 100 Mbps or 1 Gbps).

In particular, the data relay 200 supports a 1 Gbps data rate, while the aggregation relay 300 supports a 500 Gbps data rate and the cable 100 is equipped with a standard Ethernet-based 1 Gbps cable. (4Pair UTP CAT. 5), or the data relay 200 and the aggregation relay 300 supports a 1 Gbps data transfer rate, while the cable 100 is equipped to support 100 Mbps based on standard Ethernet (Ethernet) Cable (2Pair UTP CAT. 5), the operation speed of the transmission control unit 240 for transmitting / processing data to correspond to the determined link transmission speed (for example, 500Mbps) is 500Mbps and the operation speed of the switching unit 230 is Mutual mismatch can occur at 1Gbps.

As such, when a mismatch occurs between the operation speed of the transmission control unit 240 and the operation speed of the switching unit 230 according to the determined link transmission speed (for example, 500 Mbps), the traffic adjusting unit 220 may determine the transmission control unit 240. By buffering data transmitted between the transmission control unit 240 and the switching unit 230 based on the operating speed (for example, 100 Mbps or 500 Mbps) and the operating speed of the switching unit 230 (for example, 1 Gbps) by an operation speed difference, Data transfer between the transmission control unit 240 and the switching unit 230 may be matched.

In addition, the traffic controller 220 is based on the operating speed of the transmission control unit 240 (for example 500Mbps) and the operating speed of the switching unit 230 (for example 100Mbps or 1Gbps), by the clock speed difference according to each operation speed By changing the clock speed of the switching unit 230, it is possible to match the data transfer between the transmission control unit 240 and the switching unit 230.

Meanwhile, when the determined link transmission rate is determined to be a specific link transmission rate at which the mismatch between the operation speed of the transmission control unit 240 and the operation speed of the switching unit 230 does not occur, the traffic control unit 220 determines the transmission control unit 240. And bypass the data transmitted between the switching unit 230 and.

The transmission control unit 210 is connected to one end of the cable 100 having at least one transmission path composed of a pair.

The transmission control unit 210 may include a data transmission speed supported by at least one of another relay device, that is, the relay relay device 300, which is connected to the data relay device 200 and the other end of the cable 100. The link transmission speed through the cable 100 may be determined based on the number of transmission paths provided in the cable 100.

In this case, the transmission control unit 210 may recognize the data transmission speed of the aggregation relay device 300 through basic information sharing with the counterpart device, that is, the aggregation relay device 300, connected through the cable 100. It will be possible to recognize the data transmission speed of the aggregation relay device 300 through various methods.

The process of determining the link transmission speed through the cable 100 will be described in more detail as follows.

When the data transmission rate of the data relay 200 and the data relay of the aggregation relay 300 satisfies a predetermined high speed transmission condition, the transmission controller 210 determines the number of the transmission paths provided in the cable 100. Detect and determine a first link transmission rate corresponding to the high-speed transmission condition as the link transmission rate when the transmission path is a specific first number, and when the transmission path is a second number less than the first number, A specific second link transmission rate slower than one link transmission rate may be determined as the link transmission rate.

For example, if the data transmission rate of the data relay 200 and itself and the aggregation relay 300 of the data relay 200 supports 1 Gbps based on the standard Ethernet, the transmission controller 210 may define a predetermined high speed transmission condition. You can judge that you are satisfied.

Thus, the transmission control unit 210, if both the data transmission rate of the data relay device 200 and the aggregation relay device 300 supports 1Gbps, and satisfies the high-speed transmission conditions, the transmission path provided in the cable 100 Detect the number of.

The transmission control unit 210 determines, as the link transmission rate, a first link transmission rate corresponding to the high speed transmission condition when the detected transmission path is a specific first number.

That is, the cable 100 may be a cable (4Pair UTP CAT. 5) having four transmission paths configured as a pair installed to support 1 Gbps based on a standard Ethernet.

In this case, the transmission control unit 210 will recognize that the detected number of transmission paths as described above is a specific first number (four), thereby linking a first link transmission rate (1Gbps) corresponding to the high speed transmission condition. Can be determined as the transmission speed.

On the other hand, if the detected transmission paths are a specific number of second numbers, the transmission control unit 210 may determine a specific second link transmission rate that is slower than the first link transmission rate as the link transmission rate.

That is, the cable 100 may be a cable (2Pair UTP CAT. 5) having two transmission paths configured as a pair installed to support 100 Mbps based on a standard Ethernet.

In this case, the transmission control unit 210 will recognize that the detected transmission paths are the specific second number (two) as described above, and thus are slower than the first link transmission speed (1Gbps), but the cable (100: 2Pair UTP) The maximum link specific second link transmission rate (500Mbps) possible in CAT. 5) can be determined as the link transmission rate.

On the other hand, the transmission control unit 210, when the data transmission rate of the data relay device 200 itself and the aggregation relay device 300 does not satisfy the pre-defined high-speed transmission conditions, and itself of the data relay device 200 and By comparing the data transmission speeds of the aggregation relay 300, if the same, the same data transmission rate is determined as the link transmission speed, and if different, the data transmission of the data relay apparatus 200 and the data of the aggregation relay 300 are different. The slower data rate of the rate can be determined as the link rate.

For example, if the data transfer rate of the data relay 200 and the data transfer rate of the aggregation relay 300 both do not satisfy the above-described high speed transfer conditions that support 1 Gbps, then the data relay device ( The data transmission speed of the self and the aggregation relay device 300 of the 200 is compared.

In this case, when the above-described high-speed transmission conditions are not satisfied, the data relay 200 supports a data transfer rate of 1 Gbps based on a standard Ethernet, but the aggregation relay device 300 supports 500 Mbps or 100 Mbps. Or, it may be the case that the data relay 200 supports 500Mbps or 100Mbps based on the standard Ethernet (Ethernet).

As such, when the above-described high speed transmission conditions are not satisfied, the transmission control unit 210 may have the same data transmission rate (eg, 500 Mbps) if the data transmission rates of the data relay apparatus 200 and the aggregation relay apparatus 300 are the same. Or 100 Mbps) can be determined as the link transmission rate.

When the data transmission speeds of the data relay 200 and the aggregation relay 300 are different from each other, the transmission control unit 210 controls the data of the data relay apparatus 200 and the data of the aggregation relay 300. The lower data rate (eg 500Mbps or 100Mbps) can be determined as the link rate.

As such, when the link transmission speed through the cable 100 is determined as described above, the transmission control unit 210 performs data transmission matching as described above by the traffic control unit 220 when the data received through the data transmission and reception unit 240 is used. When received after coarse, the data is transmitted to the aggregation relay device 300 through the cable 100 to correspond to the determined link transmission speed.

In more detail, the transmission control unit 210 determines the link transmission rate as described above in the uplinking process of providing data from the terminal device 10 of the subscribers located in the building to an external network (eg, the Internet).

Coding process, it is possible to simultaneously transmit the coded data in full-duplex transmission through each transmission path provided in the cable (100).

For example, when the transmission control unit 210 determines the second link transmission rate, that is, 500Mbps as the link transmission rate in the above-described link transmission rate determination process, the transmission control unit 210 is based on the 2D-PAM5 line coding scheme set corresponding to the 500Mbps link transmission rate. The received data may be converted into two code symbols 2D having a 5-level PAM (5-level pulse amplitude modulation) signal form.

In addition, the transmission controller 210 may transmit the converted symbols to the aggregation relay apparatus 300 by simultaneously transmitting the converted symbols through a full-duplex transmission method through each transmission path provided in the cable 100: 2Pair UTP CAT.5.

On the other hand, when the transmission control unit 210 determines the first link transmission rate, that is, 1 Gbps as the link transmission rate in the above-described link transmission rate determination process, the transmission controller 210 based on the 4D-PAM5 line coding scheme set corresponding to the 1 Gbps link transmission rate.

After data coding is performed according to the coding scheme corresponding to the determined and determined link transmission rate, data transmitted through the cable 100 according to the full-duplex transmission scheme will be received.

Accordingly, the transmission control unit 210 receives data simultaneously transmitted in the full-duplex transmission method through each transmission path provided in the cable 100, and decodes and outputs the data according to a coding method corresponding to the determined link transmission rate. The data provided by the transmission control unit 210 may be transmitted from the data transmission / reception unit 240 to the corresponding terminal device 10 through the trapping adjustment unit 220 through the downward transmission of the switching unit 230.

Here, the cable 100 may be a cable (2Pair UTP CAT. 5) having two transmission paths composed of pairs installed to support 100 Mbps based on standard Ethernet.

And, the transmission control unit 210, without the process of determining the link transmission rate through the cable 100, the specific link transmission rate (500Mbps) of the maximum possible level with the cable (100: 2Pair UTP CAT. 5) manually set It is preferable that it is done.

Accordingly, when the data received through the data transmission / reception unit 240 passes through the data transfer matching as described above of the traffic control unit 220, the transmission control unit 210 may correspond to the preset link transmission speed. The cable 100 is transmitted to the aggregation relay device 300.

That is, the transmission control unit 210 codes the received data based on a preset coding scheme corresponding to the manually set link transmission rate, and transfers the coded data through each transmission path provided in the cable 100. Simultaneous transmission is possible by transmission method.

For example, the transmission controller 210 may generate a 5-level PAM (PAM5: 5-level Pulse Amplitude Modulation) based on a 2D-PAM5 line coding scheme set corresponding to a preset link transmission rate, that is, 500 Mbps. Can be converted into two code symbols 2D having a signal form.

In addition, the transmission controller 210 may transmit the converted symbols to the aggregation relay apparatus 300 by simultaneously transmitting the converted symbols through a full-duplex transmission method through each transmission path provided in the cable 100: 2Pair UTP CAT.5.

Meanwhile, in the process of downlinking data from an external network (eg, the Internet) to terminal devices 10 of subscribers located in a building, the data relay 200 transmits the link transmission speed as described above from the aggregation relay device 300. After data coding is performed according to the coding scheme corresponding to the determined and determined link transmission rate, data transmitted through the cable 100 according to the full-duplex transmission scheme will be received.

Accordingly, the transmission control unit 210 receives data simultaneously transmitted in a full-duplex transmission method through each transmission path provided in the cable 100, decodes and outputs the data according to a preset coding method, and accordingly, the transmission control unit 210. The data provided by the data transmission / reception unit 240 will be transmitted from the data transmission / reception unit 240 to the corresponding terminal device 10 through the trapping control unit 220 through the downward transmission of the switching unit 230.

Hereinafter, a data relay as the aggregation relay 300 will be described with reference to FIG. 3.

In addition, the data relay 300 according to the present invention may further include a switching unit 320 and a traffic control unit 330.

The data transmission and reception unit 310 may include a communication module for transmitting and receiving data from the outside.

Accordingly, the data transmission / reception unit 310 may receive data corresponding to the terminal device 10 to transmit to the specific terminal device 10 from an external network (eg, the Internet), or the specific terminal relay device 200. Data corresponding to the specific terminal device 10 that is relayed / transmitted through may be transmitted to an external network (for example, the Internet).

The switching unit 320 performs a switching operation for data upward transmission and downward transmission between the data transmission and reception unit 310 and the transmission control unit 340.

That is, the switching unit 320 switches the data downlinked from an external network (eg, the Internet) to the transmission control unit 340 through the data transmission / reception unit 310 to transmit to the specific terminal device 10. In addition, a switching operation is performed to upwardly transmit the data provided from the transmission control unit 340 to the data transmission / reception unit 310 so as to transmit the data provided through the data transmission / reception unit 310 to an external room (eg, the Internet).

The traffic conditioner 330 matches data transfer according to an operation speed between the transmission controller 340 and the switching unit 320 according to the link transmission speed determined by the transmission controller 340.

Since this corresponds to the data relay 200 of the data relay 200, that is, the terminating relay 200 described with reference to FIG. 2, detailed description thereof will be omitted.

The transmission control unit 340 is connected to one end of the cable 100 having at least one transmission path composed of a pair.

In addition, the transmission control unit 340 may include a data transmission rate supported by at least one of the other relay device, that is, the terminal relay device 200 connected to the data relay device 300 and the other end of the cable 100. The link transmission speed through the cable 100 may be determined based on the number of transmission paths provided in the cable 100.

In this case, the transmission controller 340 may recognize the data transmission speed of the terminal relay device 200 through basic information sharing with the counterpart device, that is, the terminal relay device 200, connected through the cable 100. It will be possible to recognize the data transmission speed of the terminal relay device 200 through various methods.

The process of determining the link transmission speed through the cable 100 will be described in more detail as follows.

The transmission control unit 340, if the data transmission rate of the data relay device 300 itself and the terminal repeater 200 satisfies a predefined high speed transmission condition, the transmission control unit 340 determines the number of transmission paths provided in the cable 100. Detect and determine a first link transmission rate corresponding to the high-speed transmission condition as the link transmission rate when the transmission path is a specific first number, and when the transmission path is a second number less than the first number, A specific second link transmission rate slower than one link transmission rate may be determined as the link transmission rate.

For example, if the data transmission rate of the data relay device 300 itself and the terminal relay device 200 supports 1 Gbps based on the standard Ethernet, the transmission controller 340 may define a predetermined high speed transmission condition. You can judge that you are satisfied.

Thus, the transmission control unit 340, if both the data transmission rate of the data relay device 300 itself and the terminal relay device 200 supports 1Gbps to satisfy the high-speed transmission conditions, the transmission path provided in the cable 100 Detect the number of.

The transmission control unit 340 determines, as the link transmission rate, a first link transmission rate corresponding to the high speed transmission condition when the detected transmission path is a specific first number.

That is, the cable 100 may be a cable (4Pair UTP CAT. 5) having four transmission paths configured as a pair installed to support 1 Gbps based on a standard Ethernet.

In this case, the transmission controller 340 will recognize that the detected number of transmission paths is the first number of four (4) as described above, thereby linking the first link transmission rate (1Gbps) corresponding to the high speed transmission condition. Can be determined as the transmission speed.

On the other hand, the transmission controller 340 may determine, as the link transmission rate, a specific second link transmission rate that is slower than the first link transmission rate when the detected transmission paths are the specific second number.

That is, the cable 100 may be a cable (2Pair UTP CAT. 5) having two transmission paths configured as a pair installed to support 100 Mbps based on a standard Ethernet.

In this case, the transmission controller 340 will recognize that the detected number of transmission paths as described above is a specific second number (two), which is slower than the first link transmission rate (1 Gbps), but the cable (100: 2Pair UTP). The maximum link specific second link transmission rate (500Mbps) possible in CAT. 5) can be determined as the link transmission rate.

On the other hand, the transmission control unit 340, if the data transmission rate of the data relay apparatus 300 itself and the terminal relay 200 does not satisfy the predefined high-speed transmission conditions, and the data relay apparatus 300 itself and By comparing the data transmission speeds of the terminating relay 200, if the same, the same data transmission rate is determined as the link transmission rate, and if different, the data transmission of itself and the terminating relay 200 of the data relay 300 is different. The slower data rate of the rate can be determined as the link rate.

For example, if the data transmission rate of the data relay apparatus 300 itself and the aggregation relay apparatus 300 do not satisfy the above-described high speed transmission conditions that support 1 Gbps, the transmission control unit 340 It compares the data transfer rate of itself and the terminal repeater 200 of 300).

In this case, when the above-described high-speed transmission conditions are not satisfied, the data relay 300 supports a data transfer rate of 1 Gbps based on a standard Ethernet, but the terminal relay 200 supports 500 Mbps or 100 Mbps. Or, it may be the case that the data relay 300 supports 500Mbps or 100Mbps based on the standard Ethernet (Ethernet).

When the high speed transmission condition is not satisfied as described above, the transmission control unit 340 may transmit the same data transmission rate (for example, 500 Mbps) if the data transmission rates of the data relay apparatus 300 and the terminal relay apparatus 200 are the same. Or 100 Mbps) can be determined as the link transmission rate.

And, if the data transmission speed of the data relay device 300 itself and the terminal relay device 200 are different from each other, the transmission control unit 340, the data of the data relay device 300 and the terminal relay device 200. The lower data rate (eg 500Mbps or 100Mbps) can be determined as the link rate.

As such, when the link transmission speed through the cable 100 is determined as described above, the transmission control unit 340 determines the cable 100 to correspond to the determined link transmission speed of the data received through the data transmission and reception unit 310. It is transmitted to the end relay device 200 through.

When receiving data simultaneously transmitted in the full-duplex transmission method from the terminating relay 200 through the, it is possible to decode the received data based on the 2D-PAM5 line coding scheme set corresponding to the 500Mbps link transmission rate.

In addition, the transmission controller 340 may transmit / relay the decoded data to an external network (eg, the Internet) through the data transmitter / receiver 310.

On the other hand, when the transmission control unit 340 determines the first link transmission rate, that is, 1 Gbps as the link transmission rate in the above-described link transmission rate determination process, through each transmission path provided in the cable (100: 4Pair UTP CAT. 5) When receiving data simultaneously transmitted in the full-duplex transmission from the terminating relay 200, the received data may be decoded based on the 4D-PAM5 line coding scheme set corresponding to the 1Gbps link transmission rate.

In addition, the data relay 300 according to another embodiment of the present invention may further include a switching unit 320 and a traffic control unit 330.

Since the data transmitter / receiver 310, the switching unit 320, and the traffic controller 330 perform the same functions described above, the description thereof will be omitted.

The transmission control unit 340 of the data relay 300 according to another embodiment of the present invention is connected to one end of the cable 100 having at least one transmission path composed of a pair.

Here, the cable 100 may be a cable (2Pair UTP CAT. 5) having two transmission paths composed of pairs installed to support 100 Mbps based on standard Ethernet.

And, the transmission control unit 340, without the process of determining the link transmission rate through the cable 100, the specific link transmission rate (500Mbps) of the maximum possible grade of the cable (100: 2Pair UTP CAT. 5) manually set It is preferable that it is.

Accordingly, the transmission control unit 340 codes the received data based on a preset coding scheme corresponding to the manually set link transmission rate, and transfers the coded data through each transmission path provided in the cable 100.

The end relay device 200 transmits the received data corresponding to the at least one terminal device 10 connected through wire or wirelessly through the cable 100 to correspond to a predetermined link transmission speed.

In more detail, when the terminal relay apparatus 200 receives data corresponding to at least one terminal apparatus 10 connected via wired or wireless communication (S30), the terminal relay apparatus 200 corresponds to a link transmission rate previously determined based on the received data. The coding process (for example, 2D-PAM5) is performed (S40), and the coded data may be simultaneously transmitted through each transmission path provided in the cable 100 (S50).

Accordingly, the aggregation relay 300 collects data transmitted through the cable 100 from at least one terminal repeater 200 and relays the data to an external network (for example, the Internet).

In more detail, when the aggregation relay device 300 receives data simultaneously transmitted through each transmission path of the cable 100 from the terminal relay device 200, that is, data corresponding to at least one terminal device 10. In addition, the data may be decoded based on a coding scheme (eg, 2D-PAM5) corresponding to a predetermined link transmission rate (S60), and the decoded data may be relayed to an external network (eg, the Internet) (S70). ).

In this case, the data classification and relaying method in which the concentrating relay 300 collects data corresponding to a plurality of end relays 200 and relays the data to an external network (for example, the Internet), corresponds to a conventional method. Omit it.

As described above, the high-speed data transmission method according to the present invention, the terminal relay device 200 and the aggregation relay device 300 is connected through a cable (100: 2Pair UTP CAT. ) Automatically determines the maximum link transmission rate through the cable 100 based on the data transmission rate supported by the mutual device and the number of transmission paths provided in the cable 100, and corresponds to the determined link transmission rate. (E.g., 2D-PAM5), data is coded and transmitted simultaneously through each transmission path of the cable 100 in a full-duplex transmission method, thereby replacing the existing cable (100: 2Pair UTP CAT. 5) for 100Mbps guarantee. It can provide high speeds up to 500Mbps without the need for expansion.

Hereinafter, an operation method of the data relay device according to the present invention will be described in more detail with reference to FIG. 5.

The operation method of the data relay device according to the present invention is connected to another relay device through a cable 100 having at least one transmission path configured as a pair (S100).

In addition, the operation method of the data relay device according to the present invention, at least any one of the other relay device, for example, the concentrator relay device 300 connected to itself and the other end of the cable 100 of the data relay device (for example 200). The link transmission rate through the cable 100 may be determined based on the data transmission rate supported by one device and the number of the transmission paths provided in the cable 100 (S110).

Here, the process of determining the link transmission rate will be described in more detail with reference to FIG. 6.

The operating method of the data relay apparatus according to the present invention recognizes the data transmission speed of the data relay apparatus 200 itself and the aggregation relay 300 (S112), and the self and the aggregation relay apparatus of the data relay apparatus 200 ( When the data transmission rate of 300 satisfies the predefined high speed transmission condition (S113), the number of the transmission paths provided in the cable 100 is sensed (S114) and when the transmission path is the first specific number, the high speed is detected. The first link transmission rate corresponding to the transmission condition is determined as the link transmission speed (S117), and when the transmission path is the second number smaller than the first number, the specific second link transmission slower than the first link transmission speed is determined. The speed may be determined as the link transmission speed (S116).

For example, the operation method of the data relay apparatus according to the present invention may determine whether the data transmission rate of the data relay apparatus 200 and the aggregation relay apparatus 300 supports 1 Gbps based on standard Ethernet. In operation S113, it may be determined that a predetermined high-speed transmission condition is satisfied.

Accordingly, in the method of operating the data relay device according to the present invention, if the data transmission speed of the data relay device 200 and the aggregation relay device 300 all support 1 Gbps to satisfy the high speed transmission condition, the cable 100 may be used. Detects the number of transmission paths provided at step S114.

In the operation method of the data relay apparatus according to the present invention, when the detected number of transmission paths is the first specific number, the first link transmission rate corresponding to the high speed transmission condition is determined as the link transmission rate.

That is, the cable 100 may be a cable (4Pair UTP CAT. 5) having four transmission paths configured as a pair installed to support 1 Gbps based on a standard Ethernet.

In this case, the operation method of the data relay apparatus according to the present invention will recognize that the detected number of transmission paths as described above is a specific first number (four), and thus the first link transmission speed corresponding to the high speed transmission condition. (1 Gbps) can be determined as the link transmission speed (S117).

On the other hand, in the operation method of the data relay apparatus according to the present invention, when the detected number of transmission paths is a specific number of second, the specific second link transmission speed which is slower than the first link transmission speed may be determined as the link transmission speed.

That is, the cable 100 may be a cable (2Pair UTP CAT. 5) having two transmission paths configured as a pair installed to support 100 Mbps based on a standard Ethernet.

In this case, the operation method of the data relay apparatus according to the present invention will recognize that the detected number of transmission paths as described above is a specific second number (two), which is slower than the first link transmission rate (1Gbps), but the cable (100: 2Pair UTP CAT. 5), the maximum possible specific second link transmission rate (500Mbps) can be determined as the link transmission rate (S116).

On the other hand, in the operation method of the data relay device according to the present invention, if the data transmission speed of the data relay device itself and the aggregation relay device 300 of the determination result of S113 does not satisfy the predefined high-speed transmission condition, Comparing the data transmission speeds of the data relay 200 and the data relay speed of the aggregation relay 300 (S115), if the same, the same data transmission rate is determined as the link transmission speed (S118), and if it is different, the data relay device. The slower data transmission rate among the data transmission rates of the self and the concentrator relay 300 of 200 may be determined as the link transmission rate (S119).

For example, in the method of operating the data relay device according to the present invention, if the data transmission speeds of the data relay device 200 and the aggregation relay device 300 both do not satisfy the above-described high speed transmission conditions supporting 1 Gbps. In step S115, the data transmission speeds of the data relay 200 and the data collected by the aggregation relay 300 are compared.

In this case, when the above-described high-speed transmission conditions are not satisfied, the data relay 200 supports a data transfer rate of 1 Gbps based on a standard Ethernet, but the aggregation relay device 300 supports 500 Mbps or 100 Mbps. Or, it may be the case that the data relay 200 supports 500Mbps or 100Mbps based on the standard Ethernet (Ethernet).

As such, when the above-described high speed transmission condition is not satisfied, the operation method of the data relay apparatus according to the present invention is the same data transmission if the data transmission speeds of the data relay apparatus 200 and the aggregation relay apparatus 300 are the same. The speed (for example, 500 Mbps or 100 Mbps) may be determined as the link transmission speed (S118).

In addition, in the method of operating the data relay device according to the present invention, if the data transmission speed of the data relay device 200 and the aggregation relay device 300 are different from each other, the data relay device itself and the aggregation relay device are different.
