ASA 5510 - how many concurrent VOIP calls can pass through?

Hi all,
I wonder how many concurrent VOIP calls can handle Cisco ASA 5510, any idea?
Gegham

hi Gegham,
Basically what the values of  50,000 and 130000  connections indicate  are lab values  tested with 80% TCP and 20% udp  traffic. (according to table a-2 in the doc below)
http://www.cisco.com/en/US/docs/security/asa/asa72/configuration/guide/specs.html#wp1170941
RTP  is udp traffic but in case of an asa and considering a customer  scenario what happens is...
1 voip call =  1 control connection (h323,sip,sccp)    +   2 or 4 rtp connections
-so a call will in total  easily consume  5  or more  connections depending on control connections you have set up .
-also this number differs depending on if the call is  voice only or video.
So to  simply answer your  questions...
1>the number of connections that a call  consumes depends on the above factors.
2>Also there is no hard number on the  number of calls an asa can handle because this depends on the controls  you use ...including nat and inspections.
Thanks,
Karthik

    Yes. sabretooth is right. It's around 32 connections. You might need to perform a hard reset on your router then reconfigure it back manually.

  • How many concurrent connections can ACS handle at once?

    Hi Experts,
    Could you please let me know how many concurrent connections ACS can handle at once?
    Is there any limitation on it?
    Our ACS version is 4.0 (1) build 27.
    Thanks in advance for your help and have a nice day!
    Regards,
    Gabor

    It depends on many other factors but as far as I know ACS can handle upto 40 Auth request per second*

  • Recommended spec can take how many concurrent users

    With the following recommended spec from Adobe website, how many concurrent users ?
    Flash Media Streaming Server system requirements
    OS : Windows Server 2003 SP2 or Windows 2008
    H/W Requirements
    -          3.2GHz Intel Pentium 4 Processor (dual Intel Xeon or faster recommended)
    -          2GB RAM ( 4GB recommended)
    -          1Gb Ethernet card

    Hi,
    The number of concurrent users really depends on your setup.
    You might want to read the blogpost from the FMS PM on this at: http://blogs.adobe.com/ktowes/2008/08/breaking_1gbps_on_flash_media.html
    "I’ve received a lot of requests lately about how much media can be delivered through Flash Media Server (FMS). As you may or may not know, FMS is held to the same limitations as most other streaming or HTTP servers, that is the available bandwidth, disk speed, memory and CPU power on a single server. When we introduced Flash Media Server 3 we increased the performance significantly to allow you to take full advantage of hardware and ultimately help to reduce the total cost of ownership. ........... read on"

  • How many concurrency request can handel in wcf

    hi
    i have a question :
    wcf support how many concurrency request a time ?
    for example i have a wcf service and a lot of (10000) client that call the wcf together 
    thanks

    I think all your clients will be able to use your WCF Service regardless of Concurrency.
    I believe that concurrency is related to the threading of the individual request. Not completely sure about that part though. But, all your clients should be able to access the service regardless of the concurrency. That would be more based on the stress on
    your server.

  • How many concurrent connections that an ACS server version 4.2 latest patch can handle?

    I have about 50 routers and layer-3 switches that autheticate via tacacs+.  The AAA server used to be on a Linux machine running open-source tacacs+ built by me.  I have a perl script that will log into all 50 devices at the same time to collect statistics.  This script is multi-threaded.  Everything is working fine so far.
    I recently out-sourced the AAA function to a 3rd party company, not by my choice.  The 3rd party uses Cisco ACS version 4.2 with the latest patch running on Windows 2003 Enterprise Server with 16GB RAM and quad processors with quad-cores, IBM x3650-M2 hardware. The connectivity between the 3rd party and my company is through a DS-3 connection.  Maximum bandwidth over this DS-3 connection is less than 10Mbps at most.
    I noticed that for the past 3 months I have multiple failures with this perl script due to authentication failure with the ACS server.  If I just run the script again a few routers/switches, there are no issues; however, whenever I started the script to log into 50 devices all at the same time, it will fail.  If I made the configuration on all routers/switches to point back to the old open-source tacacs+ server, the issue goes away.  The minute I switched back to the
    new ACS server, the issue came back.  If I modified the script to hit one device at a time, it works fine.  I think it is the ACS server can not handle a lot
    of AAA requests at the same time.
    Does anyone know how many concurrent connections that an ACS 4.2, with latest patches on Windows 2003 Enterprise Server with lot of memory and CPU power, can handle?  I can't seem to find this anywhere on Cisco website.
    Thanks in advance.

    No, Im not saying ACS cannot cope.
    Concurrency and latency are very different things. ACS CSTacacs can handle many 100s of simple authentications/authorisations per second with users in the internal database. If 1000s of devices all send traffic in the same instant it would take some seconds to work through the backlog of traffic.
    Also, worth considering that a limited number of tasks within ACS (or threads) can actually handle a much greater number of "logins" because they are generally multi-message allowing ACS to keep lots of plates spinning.
    If users are in an external databases the latency (per authentication) can increase depending on where the users are (eg Windows AD) and if bad enough can have a serious effect on the overall authentication rate. At which point customers normally turn to load balancing.
    If your device timeouts are 20 seconds (totally reasonable) I suggest the issue is more likely to be something else... a bug, perhaps specific to v4.2?

  • How to find out how many concurrent users using web application?

    Hi all,
    I have a web application deployed using 9iAS. I am trying to find out how to find out how many concurrent users are using this application at any one time. According to Oracle there is no way to see this information using the enterprise manager interface.
    Does anybody out there know how I can find out this information in real time? Failing that, are there any good analysis tools out there that display usage to the minute (all the tools I have found show usage by hour which is not sufficent for my needs).
    Any help would be much appreciated,
    Caroline

    I know I haven't heard of any software to do this, but this also sounds like a really hard problem to try and really analyze well.
    The trick is, you might "infer" how long a user is using an application based on when cookies are set and when they're set to expire. If that's a long time, though, that could count far more "concurrent" users than are actually there. A user could simply close the application at any time and stop using the application; you can't really detect that because the server isn't "told" when the user closes their browser or goes somewhere else.
    A good perl script might be able to read the Apache access log and tell you how many unique IPs asked for a given directory in which various applications are stored in any 5 minute span of time... that could be something like an indicator of "concurrent" users.
    If you don't know Perl, I'd suggest getting the O'Reilly & Associates book on Perl and learning it, because the more I think about this, the more this sounds like a textbook example for applying a Perl script.

  • How many ways to call a javabean?

    how many ways to call a javabean and how a caller application know where the javabean is?

    how many ways to call a javabean A java bean is an object whose class follows a naming convention for its accessor methods, and may optionally provide additional metadata in a BeanInfo object.
    You can call the methods directly, or throw reflection, just the same as any other java object.
    how a caller application know where the javabean is?Normally the bean is used as a self contained component, and the calling application is a framework that uses reflection and introspection to manage the components. So the sort answer is 'it's probably where you last put it'.

  • How to count how many times the caller calls by using UCCX script?

    Hi there,
    My customer wants to do a few changes for their script as below:
    At the beginning of the script they are planning to add a new menu item, it will announce their new privacy policies and to continue the user must press the number one to continue to the Welcome.  If they do not press 1 then the message should repeat itself and if they again do not press 1 they should be transferred over to a live operator who will explain things and then be able to transfer them back to the message so that they can press 1 and continue.
    I modified their script as attached file, but i don't know how to count how many times the caller calls in "Get Reporting Statistic".
    Any helps would be appreciated.
    Thanks.

    Hi Aaron,
    At beginning, i want to use a variable to get number of mistake for the same caller, then we will send the call to right place to fulfill the customers' needs. 
    Do you have any suggestion for the new posted script?
    Thanks.

  • Notifying PBX if Voip calls can't be completed from WAN

    I have 10 2621XMs each connected directly to G3 PBXs. They supply VOIP call lines to the PBX via a direct T1 (NM-HDV-1T1-24). However, when the direct T1 is up between the PBX and the CISCO router, how do I tell the PBX that VOIP calls can't be completed? This, in it's simplest form, would be due to a Frame outage on the WAN side, or perhaps internal call issues in the cloud. Using basic configs, the PBX will only know it when the direct connect T1 is down not the WAN T1 on the other side of the router. Is there any proven ways to track other interfaces or routing and convey that to the voice-ports by seizing the unused ports or taking down the direct connect T1?

  • How many concurrent users on a FMS?

    We want to stream live Town Hall meetings with the majority
    of the users viewing it from our inTRAnet. 320x240, 30fps, Dual 2.8
    GHz, 4 GB widows server. Anybody with similiar setup using FIMS to
    service 200 or 500 concurrent users? We have two campuses and I
    need to know if I will need to spec a second server if we get above
    a certain number. How many concurrent users can I supprot with the
    above configuration? Thanks

    FMS should be able to handle your 500 clients with no problem
    using the configuration you mentioned (some of my apps routinely
    see many times more than that on a similar server). I use a
    slightly beefier processor in my boxes though... quad core
    Kentsfield Xeon / 4GB ram.
    That said, also make sure you have enough throughput at your
    NIC to handle the traffic. At 500 concurrent clients, a low
    bandwidth stream of 300kbps puts you at about 150Mbps, so you'll
    want to run the numbers before you commit to a single serves in
    case you can't get enough network juice to a single box.
