Abstract

A content delivering method for computer network and system are provided. The present invention classifies nodes participating in content transmission into a transmitting group and a receiving group, and uses the groups to manage the nodes dynamically entering or quitting, and the management includes grouping, monitoring and reflecting update of CDS of group controlling information. Real time management for nodes is achieved through CDS, and the nodes in the transmitting group communicate information according to nodes recorded in the CDS. Multiple nodes in the transmitting group cooperate with each other in transmitting content. Firstly, transmission tasks are assigned to nodes in the transmitting group, and then, nodes in the transmitting group divide assigned content into many blocks and package them and transmit to nodes in the receiving group, and nodes in the receiving group which have received content packages exchange the content packages in the group according to the control data set. Therefore, the content is simultaneously transmitted from a plurality of nodes to other a plurality of nodes, and content transmission speed is high.
