Re: [openmeetings-user] Re: Using openmeetings in Low Bandwidth Environments
Good Day, Thanks Alvin and Ambarish for your inputs. Our case scenario is one teacher taking the class only his video will be shown to all connected also a presentation will be loaded on the white board as the study material. The issue i was facing during the test was that the clients are mostly connected to 256 kbps connections and they are getting good audio but the video is getting stuck. We have made some changes in the video quality side and changed the framerate to 15 frames per sec hope this will make things better. Any way i am having a testing today will get back with the details after the testing is done. Thanks Anand Ayyappan Formal education will make you a living; self-education will make you a fortune. - Jim Rohn Visit http://indya.co to post classifieds for free http://www.mozilla.com/?from=sfxuid=165364t=557 On Sat, Oct 29, 2011 at 9:37 PM, aalimbuyug...@bellsouth.net aalimbuyug...@bellsouth.net wrote: Anand, I did some load testing the last couple of weeks and here are some of the stats and observation that might help you: 1.

This is the typical presentation type conferences where only the moderator goes through his materials and chat questions are coming through. Also, the desktop sharing quality at this point was set to high so you still have some option to downgrade the bandwidth use. 2. If you start adding voice, multiple moderators, mutliple people sharing desktops, multiple people chiming in the whiteboard, etc.. the bandwidth usage spikes and can consume about up to 4-6 Mb per moderator. You have to remember that these are spikes are not consistent usage. But if your network connections are lower than that, then you will easily see degradation in the conference. I don't know what type of features and number of attendees you were planning to use OM. But overall, I've seen commercial products behave in the same fashion so OM is not that different from them. If you need more details and the exact stats, I can provide that next week when I'm back in the office.

Re: [openmeetings-user] Re: Using openmeetings in Low Bandwidth Environments
HI All, Had testing yesterday evening every thing went fine except and audio video sync. The voice quality was good but it was never synchronized with the video and also the video was freezing mostly. It would be of great help if any one can suggest a method to prevent this issue from occurring. Expecting a positive response from all. The test scenario was this. Server : Ubuntu OS with 4 Gb Ram and 1000 mbps connectivity. Moderator / Teacher : 1 Mbps upload link User : 512 kbps Only the moderator video was shown with audio from user side (only one user at a time). A slide was also played along with chat from the users.
