Abstract: The present disclosure belongs to the field of data transmission, and provides method, device and system for downloading data blocks of resource files. The method includes: when a target peer needs to download a target resource file, the target peer notifies a tracker server of a file size and a URL of the target resource; the tracker server forwards the file size and the URL to super peers preset in a P2P network to notify the super peers to prepare data blocks of the target resource file meeting the file size and the URL; after the super peer is ready, the tracker server recommends the super peer to the target peer in a form of a peer list; furthermore, the target peer downloads the data blocks of the target resource file from the super peer. With technical solutions of the present disclosure, validity of the resource file downloaded by the target peer may be guaranteed.

Abstract: The present disclosure discloses a method and a device for downloading a resource file, which belongs to data transmission technologies. The method is applied to a client in a peer-to-peer network, including: receiving a download request for a target resource file, and determining a data block download sequence of the target resource file (201); adjusting a download priority of each of the data blocks of the target resource file in real time according to the data block download sequence and a data block consumption progress of the target resource file (202); and downloading the data blocks of the target resource file through a plurality of download paths with different network qualities based on the adjusted download priority of each of the data blocks (203).

Abstract: The present disclosure provides a method for managing resource state information and a system for downloading a resource, which belongs to network communication technologies. According to the method, a target super node receives a file identification of at least one target resource file sent by a Tracker server (204); the target super node configures a download service of each of the at least one target resource file according to the file identification and a local resource storage state (205); and the target super node feeds back service configuration information of each of the at least one target resource file to the Tracker server (206).
