Embodiment Construction

[0036] figure 1 It is a system block diagram of a virtual private network communication system according to an embodiment of the present invention. Please refer to figure 1 , the virtual private network communication system 10 includes a server 110 and routing devices 120 , 130 . In fact, the virtual private network communication system 10 may include multiple routing devices. For the convenience of description, the routing devices 120 and 130 are used as representatives in this embodiment for illustration.

[0037] The routing devices 120 and 130 are the egresses of the private networks 150 and 160 to the Internet 140 outside the private networks, and provide services such as NAT for each host under the private networks 150 and 160 . For example, the private network 150 includes hosts 151 - 153 , and the routing device 120 configures a virtual IP address in a virtual subnet segment to the hosts 151 - 153 respectively. When the hosts 151-153 intend to connect to the externa...

Abstract

The invention provides a virtual private network communication system, a routing device and a method thereof. The virtual private network communication system includes a server and multiple routing devices. A plurality of routing devices respectively send a piece of registration information to the server, wherein the registration information includes an identification character string. The routing device includes a first routing device and a second routing device, wherein the first routing device sends a positioning request to the server, and the server transmits the positioning request to part or all of the routing device according to the identification string, when the second routing device When the device receives the positioning request, the second routing device returns positioning information to the first routing device through the server according to the positioning request. The first routing device directly establishes a connection with the second routing device according to the positioning information, and transmits data after the connection is established.

Description

technical field [0001] The invention relates to an Internet communication system, in particular to a virtual private network communication system, a routing device and a method thereof. Background technique [0002] With the rapid popularization of the Internet, under the framework of the fourth version of the Internet Protocol (Internet Protocol Version 4, hereinafter referred to as IPv4), the number of public Internet Protocol addresses (Public Internet Protocol address, hereinafter referred to as Public IP address) is no longer sufficient for Rapid emergence of a large number of Internet users. Therefore, after the concept of a private network (Private Network) or an enterprise intranet (Enterprise Intranet) was proposed, private networks have been widely used by various organizational systems today. [0003] The request for comments (Request For Comments, hereinafter referred to as RFC) issued by Internet Engineering Task Force (Internet Engineering Task Force, hereinaf...
