Re: [asterisk-users] Network architecture
Hi all, Here I a have a question and hope that someone give me the right answer...Is it better to use Intel CPU inside the hardware where I need to install Asterisk or AMD? It's better to use 32 bits or 64 bit and what is the difference between both of them?

By definition, the total accomplished must be less with VMs, because the hypervisor will take some CPU cycles. While this would appear to be the case at first glance, there's something more subtle going on here. In this particular case, there are data structures inside of Asterisk that get less efficient as you put more and more calls through the system. Let's take a linked list of channels for example... when you have ten calls on the system, it's fairly simple to walk down the list of channels and find the channel you're looking for. When you have a thousand calls on the system, that's certainly less efficient. This should make it apparent why the resource requirements for Asterisk don't scale linearly with the call volume. Or, to put it another way, you you can think of splitting the calls across two VMs as a crude way of bringing some efficiency back into those structures. Now, in the interest of full disclosure, I used the idea of a linked-list above only as an example. Many of the changes in Asterisk between 1.4 and 1.6.0 have been to re-plumb a lot of the internal structures to behave better under higher call volumes (things like replacing linked lists with hash tables, etc.). The Asterisk developers are continuing to work on the efficiency of the code data structures within Asterisk, but in the meantime, I hope I've given you some insight into why splitting calls across virtual machines on the same box can offer improvements, despite the overhead of running a hypervisor. -- Jared Smith Digium, Inc. | Training Manager ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

First off I think you would have a rough time making one server handle so many calls. It also depends heavily on whether or not you will be transcoding those calls. Regardless you should split the load for the simple reason that such a high density service would be in absolute tatters if your single point of failure failed for any reason.

Re: [asterisk-users] Network architecture
found out that the best solution is to use OpenSips as SIP OpenSIPS is a great free software proxy. 1- Is there any Software limitation on asterisk regarding number of simulltaneous calls? There isn't any explicit limitation in Asterisk or OpenSIPS that I'm aware of, but you are limited to processing power, memory, bandwidth, etc. 2- Can 1 asterisk server handle 5000 simuitaneous calls if I have the appropriate hardware? There are a lot of factors to consider, but I'm sure you could do it if you are determined. Not the wisest option however - see below. 3- It's etter to have one asterisk server for hadling 5k simultaneous calls or divide the load on different servers? I would split it up and keep each server under 50% load during normal activity. That way you can handle peak load and balance if one or more servers fail. Try not to put more than 200-400 calls on each server, depending on your configuration. That would be 100-200 calls per server with 50% load. For 5,000 concurrent calls, that means 25 servers assuming decent hardware and 50% load. That might not be an option. You may be able to split up some of the servers into multiple VMs -- maybe five servers with five VMs each. You may be able to get away with 90% regular load if 5,000 concurrent calls is never to be exceeded. Anyway, there are many factors to consider. More information is definitely needed.
