KDE4 Decibel You are not alone! http://decibel.kde.org/ Dipl.-Technoinform. Tobias Hunger basysKom GmbH 23/09/06 Tobias Hunger / KDE4 1 What is the fuss about? What do we want to do? 23/09/06 Tobias Hunger / KDE4 2 Defining Decibel

  1. KDE4 Decibel – You are not alone! http://decibel.kde.org/ Dipl.-Technoinform. Tobias Hunger basysKom GmbH 23/09/06 Tobias Hunger / KDE4 1

  2. What is the fuss about? What do we want to do? 23/09/06 Tobias Hunger / KDE4 2

  3. Defining Decibel Decibel will be a real time communications framework What is real time communication • Instant Messaging • VoIP/Video conferencing • Computer Telephone Integration (CTI) Why a framework? • communication is one of the fundamental use cases of computers • integrated communication is a prerequisite of collaboration 23/09/06 Tobias Hunger / KDE4 3

  4. Technologies Which technologies exist? 23/09/06 Tobias Hunger / KDE4 4

  5. Technologies: Telepathy Telepathy is a RT communications infrastructure • Defines DBus interfaces to access RT communication services • desktop independent specification • low level API • hosted at freedesktop.org • Implementation of jabber protocol is available, used in existing products. • Gnome seems to be heading into this direction URL: http://telepathy.freedesktop.org/wiki/ 23/09/06 Tobias Hunger / KDE4 5

  6. Technologies: Telepathy II Connection Manager: • Implements protocol(s) Connection: • Represents one connection to one server using one of the protocols supported by the Connection Manager Channel: • Represents one class of information transmitted over a connection 23/09/06 Tobias Hunger / KDE4 6

  7. Technologies: Tapioca Tapioca used to be a infrastructure competing with Telepathy. Today they implement the Telepathy specification. • Qt Bindings for Telepathy (QtTelepathy) with raw DBus bindings • “Convenience wrapper” QtTapioca hiding some of the messier details URL: http://tapioca-voip.sourceforge.net/wiki/index.php/Tapioca 23/09/06 Tobias Hunger / KDE4 7

  8. Why Decibel? What will Decibel offer in addition to all that? 23/09/06 Tobias Hunger / KDE4 8

  9. Decibel: Houston • Provides desktop independent DBus interfaces to high level RT communication features. • Persistently stores user data (accounts, preferences, etc.) • Starts/stops Connection Managers as required • Starts/stops desktop dependent components as required. Houston AccountManager ProtocolManager ComponentManager Telepathy Connection Manager Connection Channel 23/09/06 Tobias Hunger / KDE4 9

  10. Decibel: Houston - AccountManager The AccountManager persistently stores the user's account data in one central place including: • Connectivity information (account is online/offline) • Visibility information (hidden, free to chat, etc.) • Privacy information (invisible to user X, etc.) • etc. 23/09/06 Tobias Hunger / KDE4 10

  11. Decibel: Houston - ProtocolManager ProtocolManager encapsulates Telepathy's Connection Managers: • Holds a list of Connection Managers installed with supported protocols • Selects Connection Manager to use for a protocol • Persistently stores preferred Connection Managers • Uses the data stored in the AccountManager to bring up Connection Managers as requested. 23/09/06 Tobias Hunger / KDE4 11

  12. Decibel: Houston - ComponentManager The ComponentManager • is a registry for components. • stores the user's preferences on which component is supposed to handle which kind of channel • is notified on New Channel events • decides what do do with a new channel by deciding on which component to use to handle it. 23/09/06 Tobias Hunger / KDE4 12

  13. Decibel: Desktop Components Specialized applications started by Houston • Desktop specific! • Handle one specific task well • Work in concert with Houston and other componets Component Houston AccountManager ProtocolManager ComponentManager Telepathy Connection Manager Connection Channel 23/09/06 Tobias Hunger / KDE4 13

  14. Status Where is the code? 23/09/06 Tobias Hunger / KDE4 14

  15. Status We are behind schedule :-( • Mostly due to HR issues But we got some things done already: • Qt bindings to Telepathy were missing [done] • QtTapioca was launched to make writing applications like Houston easier [in progress] • Houston implementation [started] • KDE specific components Your help is welcome! 23/09/06 Tobias Hunger / KDE4 15

  16. PS PS: 23/09/06 Tobias Hunger / KDE4 16

  17. BoF Session Please consider participating in the BoF Session “Realtime Communication & Collaboration” on Tuesday, September 26th, 6pm to 7pm, LB04 23/09/06 Tobias Hunger / KDE4 17
