Embodiment Construction

[0070] The specific embodiments of the present invention will be described in detail below in conjunction with the drawings. The structures described in the drawings and embodiments of the present invention are basically preferred embodiments, but the description of the preferred embodiments does not include all the spirit of the present invention. Therefore, changes and replacements to specific embodiments by those skilled in the art should be included in the protection scope of the present invention.

[0071] According to the present invention, in a communication network, clients connected to a system including a proxy server and client information are provided to a server. In particular, client information is provided to a server in a server communication network including various relay devices. In this scenario, the original data packets transmitted by the clients connected to the system are provided to the client and the server without any changes to the original data pac...

Abstract

The present invention relates to a relaying system and method for transmitting an IP address of a client to a server using an encapsulation protocol. The relaying system comprises: a first proxy; and at least one second proxy or a bridge router. The first proxy reconstitutes a packet by receiving an archetype packet which includes an IP address of a client in a header thereof, and then adding the archetype packet to the inside of an encapsulation packet consisting of a header and a payload using a predetermined encapsulation protocol. The at least one second proxy or the bridge router extracts the archetype packet attached to the inside of the encapsulation packet, and then transmits information on the IP address of the client to a server. According to the present invention, a host server is capable of providing a service using information of a packet header such as an IP address of a terminal. Also, the presence of a proxy cannot be known. In addition, tunneling communications are conducted between two terminals, and can be conducted without special modification to the terminal and the host server or installing a program. Furthermore, there is an advantage in terms of security because the capsulation protocol is used, and it is possible to rapidly find the encapsulation packet.

Description

technical field [0001] The present invention relates to a relay system for connecting a client to a server through a communication network, and in particular to a relay system and method for sending the IP address of the client to the server using an encapsulation protocol. The relay system can transmit data packets to To the destination (server), during wired / wireless communication through a relay device (such as a proxy server or gateway), this relay system can keep the transmitted data packets in the same form as the original transmission of the user (client). Background technique [0002] Servers and user PCs are the starting and ending points of data transmission, and such starting or ending points are called end systems (ES). [0003] Networks are used to connect end systems together, and the devices that sit between end systems are called intermediate systems (IS). Multiple intermediate systems are used to direct data to its destination, enabling communication betwee...
