This invention discloses a method and device for content transmission on P2P network, including: dividing the content into multiple blocks and mark each of them; dividing nodes participating in content transmission into at least two groups; selecting part or all members from the content-transmitting groups to participate in the distribution of the blocks, in which the nodes respectively transmit the distributed blocks to part or all members of the corresponding content-receiving groups; controlling the members of the content-receiving groups who have received the blocks to transmit the content to other members in the their own group. In this invention, the nodes are divided into groups, the content blocks are actively transmitted between groups, and the members in the same group also can exchange content blocks actively through management of the control dataset, therefore, the node can fully schedule the resources of each node without interrogating the other nodes. Thus the real-time performance of transmission can be enhanced.
