Description

How to measure data transmission / reception speed of communication device connected to network

The present invention relates to a communication device connected to a network, and more particularly to a method for measuring the transmission and reception speed of data.

There is a method of configuring a network using a telephone line for the purpose of communication with a computer and a method of configuring a local area network (LAN) through a separate line. In the case of the LAN, a device for connecting the computer to another computer must be separately provided. These devices have separate baud rates. However, there are many cases where the actual transmission speed when connecting using the LAN is different from the theoretical transmission speed between the devices displayed on the device.

Accordingly, an object of the present invention is to provide a method for actually measuring the download speed according to data communication.

In order to achieve the above object, the present invention provides a method for measuring a data reception speed of a communication device having a network connection device, the method of designating a data to be received and selecting a region of a memory to be received, and the reception is started when the selection is completed. Storing the reception start time in the memory and performing a reception; storing the reception end time in the memory at the end of the reception; calculating a difference between the stored reception end time and the reception start time; And a method of measuring a data transmission / reception speed of a communication device connected to a network, wherein the received data is calculated by dividing the amount of the received data by the required time.

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

1 is a network structure diagram of a LAN for computer-to-computer communication.

In the case of the communication using the LAN, there is a method of communicating by wire and a method of communicating using wireless as shown in FIG. 1, and when using the wireless, the communication is performed by a packet. In addition, when connecting a network, as shown in FIG. 1, there is a method of communicating between computers of subscriber computers 201 to 206 through a host computer 100 at the center, or by connecting each computer by a single line through a dedicated line. .

2 is a schematic block diagram of the computer. Hereinafter, the present invention will be described in detail with reference to FIG. 2.

The control unit 111 controls the overall operation of the computer and controls the operation of measuring the data transmission speed of the wired / wireless network according to the present invention. The memory 112 is divided into a program memory (not shown) and a data memory (not shown). The program memory stores a program necessary for performing basic operations of the computer, and the data memory temporarily stores data generated during program execution of the program memory.

The computer may also have an auxiliary memory for storing a particular program. The printer 113 prints image information, text information, and the like under the control of the control unit 111 as one of the output devices. The scanner 114 reads and encodes image information with one of the input devices under the control of the controller 111 and outputs the encoded information to the controller 111. The key input unit 115 includes a keyboard (not shown), a mouse (not shown), and the like, and outputs a key input signal necessary for executing a program to the controller 111. The monitor 116 converts and displays the character information or the image information formed by the control of the control unit 111 into an image. The wired LAN 117 enables wired communication during network connection according to the present invention under the control of the control unit 111. The wireless communication transmitter / receiver 118 modulates data to enable wireless communication in the transmission mode under the control of the control unit 111, outputs a radio signal to the antenna ANT, and demodulates the data to be processed by the computer in the reception mode. To the control unit 111.

3A to 3B are flowcharts illustrating a data transmission rate measurement control according to an exemplary embodiment of the present invention. Hereinafter, the present invention will be described in detail with reference to FIG. 3. The invention is also invented to run on Microsoft Windows 95 or Windows TECHNOLOGY: NT.

There are two cases of data rate measurement: download and upload. Hereinafter, the present invention will be described taking the case of a wired download as an example.

In step 31, the controller 111 checks whether a key input signal applied from the key input unit 115 is a network connection request signal. The control unit 111 proceeds to step 33 if the network connection request signal is a test result, or proceeds to step 65 to perform the corresponding function and ends. When the controller 111 proceeds from step 31 to step 33, the controller 111 attempts to access the network through the FOS cable by controlling the wired LAN 117. In step 35, the controller 111 checks whether the network is successfully connected. The control unit 111 proceeds to step 37 when the test result connection is completed, and continues to perform the network connection of step 33 if the connection is not completed. In step 37, the control unit 111 checks whether the signal applied from the key input unit 115 is a download speed measurement request signal. If the download speed measurement request is requested, the controller 111 proceeds to step 39; otherwise, proceeds to step 65 to perform the function and ends.

In step 39, the control unit 111 selects data to be downloaded from the connected computer according to the key input signal of the key input unit 115, and proceeds to step 41 to designate a table (directory) to be downloaded and stored in the memory 112. In step 43, the controller 111 displays a message on the monitor 116 inquiring whether the selection is to be completed and executes the download, and checks the key input signal applied from the key input unit 115, proceeds to step 45 if the download start signal is reached, or step 39 Proceed to The control unit 111 stores the downloaded time in step 45 in the memory 112 and proceeds to step 47 to download the data selected in step 39 through the wired LAN 117. The control unit 111 checks whether the download has ended in step 49 and proceeds to step 51 when the download of the test result is finished, and continues with step 47 when the download is not finished. The control unit 111 stores the time at which the download is completed in step 51 in the memory 112 and calculates the required time in step 53.

[Equation 1]

The elapsed time can be calculated by the calculation method of Equation 1 above. In step 55, the controller 111 checks whether the elapsed time calculated by Equation 1 is 0 seconds. If the elapsed time is 0 seconds, the controller 111 proceeds to step 61; In step 55 to step 57, the control unit 111 calculates the downloaded speed.

[Equation 2]

Equation 2 can actually measure the average value of the transmission rate through the LAN. In step 59, the control unit 111 displays the name of the downloaded data, the size of the data, the required time calculated through Equation 1, and the transmission rate calculated through Equation 2 on the monitor 116.

On the other hand, if the process proceeds from step 55 to 61, an error message of the speed measurement to be downloaded is displayed on the monitor 116, and the process proceeds to step 61 to display a message on the monitor 116 asking whether to retry the speed measurement. The control unit 111 checks the key input signal applied from the key input unit 115 and proceeds to step 39 if the download speed is a re-measurement request signal, or ends.

The speed of upload as well as download can be calculated by the method of Equation 1 and Equation 2 above and can be equally used in wireless network communication.

As described above, the data transmission speed of the wired / wireless network is actually calculated to detect the average transmission speed, so that the actual transmission time of the network connection device can be known, and the network traffic status can be known.
