h1. Home * [[Study of bittorent protocol]] * [[Study of UPNP]] * [[Study of Thrift]] * [[Protocols]] h2. Brainstorming * Core and GUI are independent. They communicate over TCP socket. ** It is possible to launch the core without the GUI. The core does not depend of any kind of graphic library. ** If the GUI crashes then the core remains. * Designed for LAN usage (full trusted peers and very high speed transfers). * Efficient (very low cpu usage). * Distributed download (multi peer downloading and no central server). ** Quicker peer first. The speed of a peer is an average over a period of time say 5 min. The A speed of an unknown a peer is maximum thus it will can be take first. unknown. If a downloading is too slow (like three time slower than the best known peer) then it can switch to a quicker free peer. ** Rarest parts first. ** A part can be resumed from any peer. ** A file from a user is identified by its name and folder. ** Fixed part size (2^24 B = 16 MB) hashed with SHA-1. Used to control the integrity of parts and to identify each part. If the SHA-1 of a part does not match 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). Each peer announces periodically he is alive with a multicast message. * 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 folders (take the first if enough available space disk otherwise the second and so one..). *** Bandwidth and CPU limitation with a single option (checkbox). **** Maybe automatically detect a running game and set this flag. * Using of "Thrift":http://incubator.apache.org/thrift/ for definition of the protocol between two peers and between the Core and the Gui. * File list with name+size. * Non blocking search. * Using of systray (optional). * Free space management. * Graphics of the transfer rate over time. * The number of concurrent download is around 3 parts and the number of concurrent upload is unlimited. * Parse meta data like ID3tag when searching.
