  2. Outline Mobile Peer-to-Peer (BitTorrent) Message model Protocol model BitTorrent messages BitTorrent protocol (and event handling) Modelling the UI DSML-Aided Development for Mobile P2P Systems

  3. BitTorrent DSML-Aided Development for Mobile P2P Systems

  4. Mobile Peer-to-Peer • Increasing capabilities of simple mobile phones • Find, access and play multimedia content with the same device • Bringing peer-to-peer technology to the player device • MobTorrent 1.1 • 31th of April • http://amorg.aut.bme.hu/projects/mobtorrent DSML-Aided Development for Mobile P2P Systems

  5. Modelling BitTorrent Easier to update the model Easier to fix bugs The protocol can be used for other content sharing solutions (more than a simple BitTorrent client) Easy to build applications on top of the protocol DSML-Aided Development for Mobile P2P Systems

  6. Message model BitTorrent messages have common structures ConstantField: this part of the message is constant SeparateField: length is not fixed but it is separated by characters FixedLengthField: length is fixed DSML-Aided Development for Mobile P2P Systems
