Embodiment Construction

[0026] In conjunction with the drawings, the present invention is further described through specific embodiments.

[0027] exist figure 1 In the process, Peer logs into the P2P network, creates a pipeline, and stores its file notification locally; Super-peer1 updates the SRDI index after receiving Peer’s login information, and notifies other Super-peers; Super-peer6 stores Peer needs When it finds that the Peer has logged in, it notifies the Peer to download the file; after the file is transmitted, Super-peer6 changes the file_flag in the file summary to 0, and publishes the file summary on the Internet to notify other Super-peer6 that has saved the file. The peer deletes the file.

[0028] exist figure 2 In the process, Peer needs to store files in the P2P network, and it sends a request to the Super-peer in the network; Super-peer1 retrieves the topology of the network after receiving the request first, and sends other Super-peers in sequence according to the order of cri...

Abstract

The invention provides a P2P push type network storage method base on JXTA, which combines the network storage and JXTA technology, uses the JXTA2.0 characteristics to store files in the Super-peer. The other Peer download files from the Super-peer or uploads files to the Super-peer after landing the network: firstly, when the Peer needs to download the files, the Peer lands to the P2P network, if there is super-peer stored with files that Peer is requested to download in the P2P network it informs the peer to download the file; secondly, when the Peer is needed to store in the P2P network, it sends request to the super-peer in the P2P network, the super-peer that has received the request detect whether the local has a memory space capable of storing the file, if so, sending a notice agreed to upload files to the Peer; Peer establishes communication channel upload files after receiving the notice agreed to upload files.

Description

technical field [0001] The invention relates to a network storage method, more specifically, relates to a JXTA-based P2P push network storage method. Background technique [0002] In recent years, P2P (Peer-to-Peer) has become a hot spot on the Internet. It is an application mode of the Internet. Any device in the network, including mainframes, PCs, PDAs, mobile phones, This application mode enables direct connection. [0003] At present, the representative research and development products and technologies of P2P are as follows: [0004] (1) Instant messaging software like ICQ. It supports multiple users to communicate in text and files, and can be interconnected with other communication devices, weakening or even getting rid of the dependence on the central server. Such communication is closer to the non-Internet communication mode. [0005] (2) Napster-like software. Users can realize file sharing, retrieval, and copying of files by installing such software, and can a...
