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. |
