  3. 3. Goal 1<br />Webconference system<br />
  4. 4. Result: Webconference system<br /><ul><li>Conference held in our public server ( with 9 participants (7 on desktops and 2 on mobile devices)</li></ul>Presentation<br />Participants list<br />Chat withauto-translation in 46 languages<br />Audioconferenceparticipants<br />Videoparticipants (theteam)<br />

  6. 6. BBB stress test (March 24th, 2011)<br /><ul><li>Server: Xeon 3450 quad core 2.66 Ghz with hyperthreading(dedicated server).</li></li></ul><li>BBB stress test (March 24th, 2011) – Overview<br />Server load:<br />7:48 – 20 voiceusersand 20 webcams (~30% CPU)<br />7:57 – 40 voiceusersand 20 webcams (~45% CPU)<br />8:05 – 60 voiceusersand 20 webcams (~70% CPU)<br />8:08 – 80 voiceusersand 20 webcams (~90% CPU): Audio starts to degrade<br />Bandwidth:<br />1 audiochannel: 60 kbit/s<br />60 audiochannels: 3,6 Mbit/s<br />
  7. 7. BBB stress test (March 24th, 2011) – Conclusions<br />PS: Eachserver is different (virtual vsdedicated, numberof cores, hyperthreading, memory).<br />Software: FreeSWITCH 1.0.6; Red5 0.91; BigBlueButton 0.8 using 16khz wide-band speex for audio (encode quality 6). <br />With FreeSWITCH is possible to enable load balance using several voice servers<br />

  19. 19. Features already implemented in the web application<br />BigBlueButton provides webconference rooms, but you still need a system to provide management tasks such as:<br />User authentication<br />Permission control<br />Webconference management<br />CRUD (create, read, update, deleat)<br />Server management<br />CRUD<br />
  20. 20. Future features for the web application<br />BigBlueButton provides webconference rooms, but you still need a system to provide management tasks such as:<br />Server management<br />Load balancing<br />Conference scheduling<br />Access statistics<br />Pre-upload of documents<br />Access to the VODs (audio, video, presentations)<br />
