Description¶

A bit brainstormed for the moment ;)

• Designed for LAN usage (full trusted peers)
• Efficient (very low cpu usage)
• Distributed download (multi peer downloading and no central server)
  • Quicker seed first. The speed of a peer is an average over a period of time say 5 min. A speed of a peer can be unknown. If a downloading is too slow (like three time slower than the best known peer) then it can switch from a quicker free seed.
  • Rarest parts first.
  • A part can be resumed from any peer.
  • Fixed part size (2^24 B = 16 MB) hashed with SHA-1. Used to control the integrity of parts and to identify a file. A file is identified by the concatenation of all the SHA1 of all its parts. If the SHA-1 of a part does not match with the given SHA-1 then it will be re-downloaded entirely.
  • Recursive folder downloading
• There is a general chat
• Multicast UDP for services discovering (maybe UPNP)
• MDI GUI with GTK2HS
  • A panel to view the current peers
  • A window to view the current downloads (leechage) and one for the current uploads (seedage)
  • A window for the chat
  • A window for searching
  • Some windows for each file browsing
  • A modal window for the settings
    • The shared folders
    • The incoming folder
    • Bandwidth limitation
• File list with name+size
• Non blocking search
• Using of systray (optional)
• Free space management
• Graphic of the transfert rate over time
