Problems solved by technology

However, VPN technology requires a server through which all data forwarding is performed (such as figure 1 ), so the bandwidth and cpu burden of the server is very heavy, and it cannot support large-scale (millions of clients online at the same time) network connections
[0004] In addition, some network application software, such as Microsoft network service (MSN, Microsoft serviceNetwork), QQ, Skype, etc., can connect multiple clients into a private network to prov

Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The data transmission method and virtual peer-to-peer network system for data transmission provided by the present invention adds a virtual IP layer to the IP layer of the original Transmission Control Protocol / Internet Protocol (TCP / IP, Transfer Control Protocol / Internet Protocol) network protocol stack on the client side , Used to obtain the public network IP address and TCP port number corresponding to the virtual network IP address from the server when the virtual network IP address is used as the destination network IP address, and encapsulate the virtual network IP address into the corresponding public network IP address , Obtain the routing path information to the public network IP address from the routing information table st...

Abstract

The invention discloses a data transmission method and a virtual peer-to-peer network for data transmission, and the data transmission method comprises the following steps: increasing a virtual IP layer at an IP layer of an original (TCP/IP, Transfer Control Protocol/Internet Protocol) network protocol stack of a client, thereby obtaining the public network IP address which corresponds to the virtual network IP address from a server and packaging the virtual network IP address as the corresponding public network IP address when taking the virtual network IP address as the target network IP address; and obtaining routing path information to the public network IP address from a routing information table stored in the server and carrying out the corresponding treatment according to the obtained routing path information. When a VPN network is constructed by applying the invention, the server does not need to forward data any longer, thereby reducing the data transmission time delay, simplifying the requirements on the performances of the server and the bandwidth and improving the network transmission efficiency.

Description

Technical field [0001] The invention relates to data transmission technology, in particular to a data transmission method and a virtual peer-to-peer network system for data transmission. Background technique [0002] In existing Internet applications, when two clients need to perform data communication and networking, data is often forwarded by the server. This mode is generally called the CS (client server) mode. With the explosive growth of personal data, people urgently need a technology that can realize direct communication between two clients. However, in real networks, there are a large number of clients that only have private IP addresses. These clients are blocked by the NAT gateway and cannot be accessed by other clients. To this end, the prior art proposes a network address translation (NAT, Network Address Translation) gateway traversal technology. By adopting certain technical measures, clients between intranets can be interconnected. Commonly used NAT gateway traver...
