[Asterisk-Users] 5,000 concurrent calls system rollout question

[Paul Mahler]

Based on our benchmarking, I am VERY skeptical of this number. I'm guessing
that you don't really have RTP streams going through the NIC.

I have tested an asterisk server with over 5000 concurrent calls.

The system setup was a P4 HT 3Ghz, 4 Gb RAM, and 1 gbps Ethernet connection
on a cisco 3560 switch.

 

This works, but puts some serious stresses on the system.

Why don't u considered using g.729 codec, this will at least lower the
bandwidth consumption significantly, and, you can overcome the CPU resource
issue by just using a server grade multi CPU xeon server.

 

I would never the less still connect the system via 2 ethernet connections,
just for some redundancy, as mentioned before in this thread.

 

Bandwidth should be about 24 kbps (half duplex) per call

 

So, 5000 * 24 is roughly 120 mbps, so a gigabit Ethernet should do just
fine.

Why not bond multiple NICs together to do a load balance output?  Would 

provide redundancy as well.
