Problems solved by technology

[0008] At present, many network data transmission technologies are implemented based on p2p, mainly in the form of exchanging the data owned by each client node in the peer-to-peer network based on the bitmap exchanged with each other, but this requires each node to exchange its own bitmap Graph information, not only the technical implementation is complicated, but also has an impact on the transmission speed and performance, resulting in poor effect on achieving low latency

Abstract

The invention provides a data transmission method based on a peer-to-peer network. The method comprises the following steps: slicing request data, and establishing at least two transmission sub-streams; selecting the transmission sub-streams by a request node, and establishing a data sharing relationship with other request nodes selecting different transmission sub-streams; and downloading a corresponding data slice by the request node through the transmission sub-streams, and receiving the data slices downloaded by other request nodes through the transmission sub-streams through the data sharing relationship. The request data are sliced and are shunt for transmission, the request node only selects one sub-stream for downloading data and obtains other data from the other nodes, thereby being simple and efficient, and the data transmission method is particularly suitable for live broadcast services. The invention further provides a data transmission system based on the peer-to-peer network.

Description

technical field [0001] The invention relates to the technical field of network data transmission, in particular to a peer-to-peer network-based data transmission method and system. Background technique [0002] With the continuous development of Internet technology, network data transmission technology is also constantly improving. [0003] In the traditional network data transmission, the client downloads the file data from the server to the local by means of the network connection with the server. In this process, because the file data has a certain size, a certain download time is required. [0004] For the client, the file transfer may be slow or abnormal due to the network bandwidth limitation, packet loss rate and unexpected abnormalities, which may cause the client to fail to obtain the requested data normally or quickly, especially for the requested file data Large or real-time, such as streaming media files, the file data transmission mode under this C / S architectu...
