My server Vs. System Requirements

[Andrew]

Hello,

Our faculty server is running on the following :

Quad Core , 3.9 GB memory , 2 GHz Processor , Ubuntu 10.04 and internet connection speed 4096/1024 Kbps

should BBB works properly on this system ? if yes what is the max no. of attendees it can preserve ?!

Thank you !

Hardware,

The hardware could run a server <25 concurrent users. But the network
should be better and symmetrical.
BBB as a server must have a lot of UPLOAD bandwidth as it streams lots
of data to every client.
Best to have BBB in a datacenter with 100MB port.

Thank you for your reply!

Actually I'm targeting about 500 concurrent users!! any suggestions and modifications on the hardware to reach this goal ?!

[Chad Pilkey]

Andrew,

Are you talking 500 users in one meeting or 500 users split between many users? If you're trying to accomplish the former you're going to have a lot of problems as BBB isn't designed for that number of users in one meeting. You would need a massive server or even multiple servers to host one meeting. If instead you're looking for 500 users across many meetings you would need to set up a bunch of BBB servers and have a load-balancer infront of them distributing the meetings as required. There's no open-source load-balancer for BBB as far as I know though so you would have to create that yourself or contact one of the companies offering support and pay for the use of theirs.

Chad,

but is it possible for one meeting of 500 or more users?
Is there any documentation of setup multiple BBB servers ?

Regards,

Nikos

Thanks Chad for your reply!

I'm now somewhat depressed as I was preparing a Webinar system to host our faculty students during the summer vacation. However, we might arrange live webinar for about 25 - 100 student and the other attend a recorded version (webcast). 

One more thing, I was asking about our internet connection as its speed is 4 MB/S. Is this sufficient :) ?!!

Nikos,

BBB has no hard coded limitation on the number of concurrent users. With that said though the recommendation is always <25 people in a meeting because we know that a decent server can handle that many users. As you get into higher user numbers CPU is likely going to be the limiting factor (as long as you have enough bandwidth). I don't think anyone has ever successfully run a meeting of that size before, but technically it's feasible with the correct hardware.

As for setting up multiple servers, there's no documentation for that. If you're looking to do that you really need to have a deep understanding about how the different parts of BBB connect together.

Andrew,
The speeds in your first post were listed as 4 megabits per second down and 1 megabit per second up. You would have trouble hosting a meeting containing 3 people on that bandwidth. For BBB you really need a server with a connection bandwidth of 100 megabytes per second up and down.

Thanks Chad !

Unfortunately the Max bandwidth in our country is 8 MB/s :). I'm depressed now more than any other moment through my life but still we might try something like Adobe Connect Pro. Hope this can work !

Thanks again for your time :)

Andrew, I am not sure how it works with mconf, but it is a branch of
BigBlueButton and they have a "webinar" mode.

The challenge with BBB is it mixes each participants stream, which adds
quite a bit of processing overhead. With the webinar mode in mconf, it
will just send participants which aren't talking the same "shared" stream.

So check out mconf's site and see if it can help you:
http://mconf.org/m/#overview

MConf and BBB exchange code between the projects. There are people on
the list that know a lot more than I do about mconf on this list.

Hi Andrew,

Don't be depressed :-).  For more information on Chad's reply, see

Hi Andrew,

The MConf team maintains a fork of BigBlueButton and they made some really good contributions back to the project (such as the layout manager and video dock).  We wish there were more teams like MConf :-).

For an overview of the MConf project, see the recordings from the recent BigBlueButton Summit:

Thanks Geoffn!

This is really helpful. I'll take a look at it.

Thanks a bunch Fred!

You solved the hardware issue but what can I do with the bandwidth ? It is only 4 MB/s Fred, only 4 :) !!!

Hi Andrew,

You have insufficient bandwidth to run a BigBlueButton server in production.

Andrew, you can put your BBB server in a commercial datacenter. What
part of the globe are you in.

BigblueButton & MCONF run well in ec2, and scaling a larger server up
for your sessions is pretty affordable if you shut it down when not in
use.

Thanks Fred and hostbbb.com !!

hostbbb.com :

I'm from Egypt and we are having data centers. I like this idea and will work on it as plan (b). Really appreciate that !

Fred:

I'm intending to use BBB in the form of webinars and I'm not going to use any webcams neither by the presenter nor by the attendees. Sharing slides and chat don't take bandwidth and the VoIP takes only 20 KB/sec so we may be able to host around 50 users (if some software upgrades were made). Also we have another internet connection of 4096/1024 Kbps which can be connected to the server too, might all of this help ?!!

Our BBB Server is running 16gb ECC RAM; 2x Quad-core Intel XEON (i forgot, but over 3 ghz) with 60mbps down 10mbps up. This for us, is sufficient for what we want it to do. But even this dell blade server and our business-class network speeds would not be sufficient for what you want to do.

You will need multiple servers, with more RAM than the one you have now. A load balancer in front of the servers (which is relatively easy to create in PHP, if you understand how these servers work --and php) and way more network bandwidth! Sometimes it seems even fiberoptic wouldn't have enough bandwidth for our BBB sessions XD

Joe,

Can you be more specific on the scenarios where your hitting your bandwidth limits?

Hi, Fred 

For presentation BBB supports upto 25 concurrent members, then what about playback..for how many concurrent users it supports, because we use BBB mainly for playback purpose, so pls give me advise.. if it not supports what are the other alternate methods..and also for playback what is the required bandwidth at user side and server side..

Pls help me in this regard..

Thanks ,

Madhukar

[Chad Pilkey]

The playback is just serving up static files so your only limiting factor would be your server's upload bandwidth. If you have too many user's trying to replay meetings at once all they should see is slow loading pages or buffering video/audio.
