ABSTRACT:
A “Mass File Sharer” (MFS) provides a mass P2P file sharing protocol with optional on-demand file access across a P2P network. Unlike conventional P2P file sharing, the MFS simultaneously asynchronously shares large numbers of files, while providing optional on-demand (synchronous) access to shared files. The MFS uses a unique metadata structure in combination with an inter-peer file/folder version analysis and an inter-peer file/folder availability analysis to share complex directory structures that may include any number of folders, sub-folders, and files. Sharing may be asynchronous and/or synchronous. Specifically, file sharing is generally accomplished as an asynchronous distribution across the network. However, when a particular peer wants direct access particular files, an on-demand access mode is used to enable synchronous delivery of shared files. This combination of asynchronous and synchronous file distribution enables the MFS to support a number of applications, such as on-demand movie viewing, file/folder browsing, etc.
