Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] In the present invention, network cards corresponding to different networks are respectively configured in the transfer server, and when the source client sends data to the destination client of different networks, the data transmission between the clients is directed to the corresponding transfer server through the relocation server , using the transfer server to provide data transfer services for the client.

[0031] figure 2 The network structure of the data transmission system provided by the present invention is shown, and the source client and the destination client belong to differe...

Abstract

The invention fits for network communication field, and provides a data transmission system and method; said system includes re-direction server and at least one transferring servers which is connected with the re-direction server, the re-direction server which is used to receive data transmission request message of client, select the transferring server which transfers data based on IP address of source client and destination client took by message; and transferring server which is used to receive data of source client and transfer said data to the destination client, said transferring server possesses at least two net cards, IP address of different net cards are corresponding with different networks. By the invention, the multiple net cards transferring server provides data transferring service for client, data transmission quality between clients is increased.

Description

technical field [0001] The invention belongs to the field of network communication, in particular to a data transmission system and method between different networks. Background technique [0002] During the communication process, clients communicating with each other may belong to different networks, or may belong to different subnet networks within the same network. Generally, the data transmission of the client between different networks adopts direct transmission or transit transmission. Direct transmission means that the source client directly transmits data to the destination client. Usually, if the source client and the destination client are in the same network, the network transmission quality of direct transmission is better. However, when the source client and the destination client are not in the same network, if the direct transmission method is used, the transmission quality of the network is usually poor due to reasons such as narrow transmission bandwidths,...
