METHOD, SYSTEM AND DEVICE FOR SENDING DATA

摘要

A method, system, node and supernode for sending data in the peer-to-peer network are provided, which belong to the technical field of the peer-to-peer network. The method includes the following steps: a request message sent from a requesting node for obtaining data is received; starting from those fragments obtained according to said request message from said requesting node, a key frame appearing for the first time is found among the fragments received; the fragments are then sent to the requesting node, beginning with the fragment in which said found key frame is located. The system includes a requesting node and a requested node. The node includes: a receiving module, a searching module and a transponding module. The supernode includes: an obtaining module and a processing module. The supply stream of the requesting node to the player is accelerated by the forwarding of fragments to the requesting node, said forwarding beginning from the fragment in which the key frame is located. In this way, the player can decode and play images more quickly and image play delay is reduced.
