Abstract

The invention relates to a distributed code storage-based network data centralized-broadcasting transmitting method, belonging to data transmission technical field, comprising: firstly storing coded data and coding information in plural servers; a user end sends request through network to plural servers; the servers receive data transmission request from the user end and sends confirm and coding information to the user end and packets the coded data and sends data packets to the user end; the user end receives the confirm information and obtains the number of data packets to be received from the coding information and receives the data packets from the servers and decodes them. And its advantages: providing downloading service by powerful servers, assuring relative stability of data service; making distributed data storage and implementing data centralized-broadcasting downloading, raising downloading rate; randomly coding data, saving network bandwidth and improving network survivability.

Description

technical field

[0001] The invention relates to a network data assembling and broadcasting transmission method based on distributed encoding and storage, and belongs to the technical field of network data transmission. Background technique

[0002] Existing network transmission methods include network unicast, multicast and broadcast. Unicast refers to a method in which a server in the network transmits data to a user terminal by establishing a network link, and is the most basic data transmission method in the network. When multiple users need to obtain the same data, it is very inefficient to establish multiple independent unicast transmission links between the server and users for data transmission, because it will repeatedly send the same data many times, reducing the network bandwidth utilization rate. Multicast is a transmission method in which a server transmits the same data to multiple user terminals at the same time. This method improves the utilization rate of n...
