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.
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.
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 />

21.
Initial strategy<br />Web application to integrate BBB into Global Plaza - Mconf-web<br />

22.
Mconf-web<br />User rooms<br />Agenda<br />Recent activity<br />Spaces (groups)<br />

23.
Integration with IM systems and social networks<br />Simplify the registraion<br />Integrate with Google Talk, Facebook, Twitter, Skype<br />1<br />The user access Mconf and chooses how he will be authenticated<br />2<br />Mconf gets the user information from the service provider<br />

24.
Webconference broadcast / invitation<br />E-mail and internal message invitations already implemented<br />

25.
Mconf can become a federated service<br />Simple and standard way to authenticate users<br />Possible services:<br />Webconference: federation users can easily access the webconference<br />Access to the recordings: asynchronous access to the service that provides the webconferences’ VOD<br />

30.
Potencial service for RNP<br />The product can potentialy become a service similar to Adobe Connect, but free.<br />Mconf is free, open source, and easily customizable to what RNP and it’s partners need<br />Create a domain “mconf.org”???<br />
