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, routing devices and a method thereof. The virtual private network communication system comprises a server and a plurality of routing devices; the plurality of routing devices respectively transmit a piece of registration information to the server; the registration information comprises an identification character string; the routing devices comprise a first routing device and a second routing device; the first routing device sends a positioning requirement to the server; the server transmits the positioning requirement to partially or all routing devices according to the identification character string; when the second routing device receives the positioning requirement, the second routing device transmits a piece of positioning information back to the first routing device via the server according to the positioning requirement; and the first routing device directly builds connection with the second routing device according to the positioning information and data are transmitted after the connection is built.

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 Version4, 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 Used by a rapidly emerging large number of network 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...
