Re: How to increase the large_fdset value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is very pesimistic formula - in real world,
when you almost always use H.245 tunneling,
you need 2 sockets (non-proxy) or 4 sockets (proxy)
per call.

Now, what'll I have to do to increase the large_fdset value, so that I
can handle 600 concurrent calls ?? As we know for 100 concurrent calls
we need 1024 sockets.

Please tell me what will be the steps and commands to configure it.
I'll be highly gratefull.

./configure --with-large-fdset=<value>

According to the docs for 600 concurrent calls you would need an fdset of at least 7200.

MAX_NUMBER_OF_CONCURRENT_CALLS * 10 * 120%

Where:
10 = 2 sockets for Q.931 + 2 sockets for H.245 + 6 sockets for RTP and other stuff
So for 100 concurrent calls you don't need more than ca. 1024 sockets in the LARGE_FDSET.


As for real world values, I can't speak to that as I'm new to gnugk myself.
