Embodiment Construction

[0059] 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.

[0060] Such as figure 1 As shown, in the present invention, the central server 101 uses the client whose network traffic meets the data transmission requirements and has an external IP as an instant messaging node to transfer and transmit the instant messaging data between the clients, thereby saving the transfer server purpose of bandwidth. Whether the client can become a node is judged and selected by the central server 101 .

[0061] In step S101, the central server 101 judges whether the client has the ability to transmit data according to the information reported by the client, and selects a...

Abstract

The invention provides a data transmitting method and system of an instantaneous communication. The transfer transmitting switches in the date between the client end and the object client end. The method comprises: a) choosing the client end with data transfer ability as node; b) choosing the node for providing the data transfer server to the client end and the object client end and then allocating a node key to the node; c) establishing the node transfer communicating channel; d) using the node transfer communicating channel to switch the data of between the client end and the object client end.

Description

technical field [0001] The invention belongs to the field of instant messaging, and in particular relates to a data transmission method and a data transmission system in instant messaging. Background technique [0002] In the process of instant messaging, the interaction of information and data between clients needs to be realized through the transfer server. The client requests the IP address of the other party from the central server, and uses the IP address to send a direct connection request to the other client. If the request is approved by the other party’s client, a direct connection will be established for communication. If the direct connection cannot be achieved due to the firewall of the other party’s client, the initiator’s client will send a relay request to the relay server and communicate through the relay server. [0003] At present, since most users access the Internet through a LAN, in order to achieve the purpose of network security, the LAN often sets up ...
