Description

[0001] UDP COMMUNICATION TEST APPARATUS AND THE METHOD THEREOF [0002]

The present invention relates to a UDP communication technology, and more particularly, to coding and compiling for changing a setting of UDP communication between different types of programs or hardware devices designed to communicate with different types of UDP packet structures The present invention relates to a UDP communication test apparatus and a method thereof.

UDP is an abbreviation of User Datagram Protocol (UDP), a kind of protocol for computers to communicate data with other computers. UDP is a protocol used in the transport layer, which is the fourth layer in the OSI model developed as a global communication standard.

The UDP packet consists of destination address, data order, checksum and real data, so it transmits the data to the other side with no transmission confirmation. The transmission speed is fast but the acknowledgment can not be made, so that the reliability is lower than TCP. Therefore, UDP is called a connection type and TCP is a connection type.

Since UDP is important for real-time security, it is used in streaming fields, VoIP, and mVoIP, which are very inefficient. Also, UDP is mostly used for server-client communication of online games. In this case, it is used because the faster response speed is more important than the data being transmitted completely. In this case, the game server often uses a method of leaving the input data transfer to UDP and recovering most of the lost key input itself or ignoring it altogether. When sending data, a mechanism is used to send two packets in duplicate to recover from the next packet even if one packet is lost. However, in case of UDP transmission, the responsiveness of user input and server are important, and important data is used together with TCP transmission.

In addition, if TCP is used in a situation where efficiency is low, but reliability must be ensured, a reliable network can be constructed using UDP by programmatically coding and implementing the reliability work in TCP. For example, some P2P systems have developed and used a separate communication method that uses UDP while ensuring reliability at the same time, and most famous is μTP used by some bit-torrent clients.

In the case of the UDP-applied software having the above-described characteristics, the setting for UDP communication is coded and compiled. Therefore, in the case of software coded in a UDP packet structure other than the software coded in the same UDP packet structure, It is not possible to perform communication by means of the network. Therefore, in the case of software that can not receive UDP communication signals (muzzle direction and trigger signal for calculation of bullet trajectories, etc.) because the server program or client program test using UDP is not completed and hardware production is not completed, the same UDP packet structure UDP communication can be performed only with coded software. In the case of software coded with a different UDP packet structure, since the packet structure is set differently, communication can not be performed, and UDP packet setting related codes And then compile the code.

In addition, in the case of the conventional commercial UDP communication test software, since the configuration of the data received through the UDP communication is not known, the received data is expressed in binary or hexadecimal (Hex) . In addition, UDP communication is difficult to change because data can not be transmitted or the data to be transmitted is also expressed in the form of binary or hex code (Hex).
