Problems solved by technology

Because the data needs to be transferred through the server, and the data is massive, the server needs to have a very high bandwidth for uploading and downloading, and as more terminals are connected, the bandwidth required is higher and the cost is higher. When a certain threshold is reached, the entire system will not work normally; and if the publisher’s data loses packets, other terminals will also lose packets, resulting in a high bit error rate

Embodiment Construction

[0026] Such as figure 1 As shown, in Embodiment 1, a data transmission method includes the following steps:

[0027] Step S10, receiving a data resource release request issued by the data resource release terminal, and notifying the download terminal according to the request. In one embodiment, the data publishing terminal is used to send a data publishing request to the terminal management server, and the terminal management server notifies the downloading terminal after receiving the request, and simultaneously sends the data resource information and the terminal information list of the terminal to the downloading terminal. This data resource takes the transmission of audio and video data in a chat room as an example. The audio and video data in a chat room is different from ordinary file downloads and has certain requirements for real-time performance. By buffering a piece of audio and video data, storing a piece of data, and then Download the small piece of data as a file...

Abstract

The invention relates to a data transmission method which comprises the following steps of: A, receiving a data resource publishing request published by a data resource publishing terminal and informing a downloading terminal according to the request; B, establishing network connection between the data resource publishing terminal and the downloading terminal according to the information; C, establishing broadcasting channels according to the network connection; and D, establishing a data link and transmitting data resources according to the established broadcasting channels. Moreover, the invention also relates to a data transmission system. In the data transmission method and system, the downloading terminal is informed according to the received data resource publishing request, network connection is established between the terminals according to the information, the broadcasting channels are established according to the network connection, and the data link is established according to the broadcasting channels for transmission of the data resources, so that the data resources are transmitted by using a plurality of broadcasting channels, the bandwidth cost is lowered, faults caused by failure of one broadcasting channel are avoided, and the error rate is reduced.

Description

【Technical field】 [0001] The invention relates to the field of Internet, in particular to a data transmission method and system. 【Background technique】 [0002] Data transmission on the network sometimes has the characteristics of strong real-time performance, massive data per unit time, and continuous data. In view of these characteristics, traditional technologies generally adopt the way of server transfer for data transmission. The transit server receives the data released by the data publisher, and then forwards it to other connected terminals according to specific rules. Because the data needs to be transferred through the server, and the data is massive, the server needs to have a very high bandwidth for uploading and downloading, and as more terminals are connected, the bandwidth required is higher and the cost is higher. After reaching a certain threshold, the entire system will not work normally; and if the publisher's data loses packets, other terminals will also...
