Data packet sharing-based large file transmission system

Abstract

The present invention discloses a data packet sharing-based large file transmission system and belongs to the large file transmission technical field. The data packet sharing-based large file transmission system of the invention comprises a terminal control unit, a cloud storage unit, a transmission unit, a subscriber unit and an addressing unit; the transmission unit comprises a first data transmission module and a second data transmission module; a cloud server is connected with the second data transmission module through an IP (Internet Protocol); and the automatic addressing module is connected with the cloud server through the IP. According to the data packet sharing-based large file transmission system of the invention, the cloud server and the automatic addressing module are adopted, so that the system can automatically store information and perform addressing through the automatic addressing module; when the same information is sent to an information receiving end, data packet content can be called at the cloud server through the automatic addressing module, and therefore, a step that an information transmitting end re-transmits the information to the cloud server can be omitted, the efficiency of information transmission can be improved, second-level transmission is realized in a real sense, the probability of file loss can be decreased, the security of the transmission of a large file can be ensured, and information transmission time can be saved for people.

Description

technical field [0001] The invention belongs to the technical field of large file transmission, in particular to a large file transmission system based on data packet sharing. Background technique [0002] As the basic form for people to store and exchange data, files have undergone several important changes with the continuous development of multimedia technology. The content has changed from text and pictures to audio and video, and the quality has changed from low resolution to high resolution. , The capacity has changed from small files to large files. As a result, the demand for exchanging large-capacity files such as high-definition pictures and video and audio is increasing day by day. In a packet-switched network, a single message is divided into blocks of data called packets, which contain address information for the sender and receiver. These packets are then transported along different paths in one or more networks and reassembled at the destination. Any host ca...
