How many concurrent streams can my server handle?

I am trying to serve streaming video over a 10 mb network and using Adobe® Flash® Media Streaming Server 3.5.  Here are the specs on the video.
Video:
Codec: On2 VP6
320x240px
frame rate: 30fps
400 kbps (VBR)
keyframe distance: 15
Audio:
Mono channel
96 kbps
 Does anyone know how many of these I could serve up concurrently?  Or is there a spec somewhere?

It might be that straightforward question to answer because your network might support "x" mbps but your server configuration including CPU,Memory,Network card you have.
If you need to do simple calculation (considering you have calculated your bandwidth for video and audio individually) it would like one client would take around 496kbps. Now that means roughly 2 clients will take 1 Mbps so 20 clients will eat up 10Mbps - so at given point of time only roughly 20 clients would be able to play stream without much of rebuffering issue.
Any number of clients would be able to connect and play but more the clients quality of service for each client might start degrading , they might start getting insufficient bandwidth messages.

    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!

  • 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 Recording Tracks Can an iBook Handle?

    I have an iBook (specifications below) and have my eye on one of these when it is released http://www.alesis.com/product.php?id=96 for recording in Logic.
    How many tracks could my iBook record simultaneously at 44.1 MHz & 24-bit with no extra CPU load - e.g Audio Unit effects. Latency is not an issue, I can turn it up as high as it wants as I will not be software monitoring.
    Would I be able to use all 8 analogue inputs without recording clicks? How do other people's iBooks perform with FireWire multi-tracking?
    Regards,
    Andrew
    iBook G4   Mac OS X (10.4.3)   1.33 GHz - 512 MB RAM - 40 GB HD - ATI Radeon 9550

    Well that's what mine can do, easily. Recording onto a lacie firewire drive I should add, although performance from the built in drive isn't unbearable.
    I'm not making it up, I can easily do that on my powerbook. I've done many sessions recently with that sort of track count, not so much the 42 channels but that was just a test of my HD.
    I can easily do a session with about 24 channels at 96khz. Obviously everyone's idea of a few versus a lot of plugins is different but say a couple on each channel, maybe a reverb and delay too.

  • How many concurrent requests can WAS support?

    Hi all,
      I want to know what is the maximum number of concurrent users/requests that can WAS6.4(latest pack) support? We are looking at around 40,000 concurrent users.. Is this feasible? If yes what is the max possible?
    Regards,
    Harsh
    PS: Would appreciate a prompt response:)

    Hi Harsh,
    I was just reading those notes that Alexander found as well and I would have to agree with him the that webdispatcher could handle the 10,000. However you have to remember that if you are running a BSP or other application located on a WAS server you have the constraints there as well.
    Now I've just done some load testing with some stress tools.
    500 concurrent connections on a Linux server dual processor 4 GB RAM and I started to see some major performance problems. Any higher and the system or at least the apps would have started to hang I think.
    So with 40,000 connections even with loadbalancing and application instances you are going to need some major hadware to handle the connections.
    Now back to your other questions.
    The WAS and the R/3 are built on the BC level, which means  the basic connections are made at that level and effected by these parameters. With a 640 Java Stack only then you have the J2EE engine only in which case the BC level is basically not there at least not like the ABAP level.
    Now if you have a single JSP page deployed on your J2EE and not making any RFC calls to your backend then you only have to worry about the dispatcher connections. However, from my understanding if you make those RFC calls then you have the connections of the backend to worry about as well.
    Now if you can gives a bit more detail of what the connections (all these 40,000 are doing) then perhaps we can come up with some alternatives that will help out.
    As for being intimidated, don't be, I'm learning this from searching as we go along as well

  • What no of concurrent connections can each server serv?

    Ok we're a startup and currently thinking about whether to use flash media streaming server or red5, or progressive streaming with lighttpd.
    In order to make a decision I would like to know how many concurrent streams can flash media server server stream until one has to purchase another license. Do any of you guys have some numbers.
    We will be streaming mp3 at low bit rates, service will be hosted within AWS EC2 (with whatever instances are available there). So if you can post some performance specs that would be great....
    Oddly enough Adobe Sales does not even know the answer... I have heard rumors that high number of concurrent connections is not a really a feature that this product is developed towards.
    Thanks for you answers.

    I'd do some more research before commiting to EC2/S3 at all. I'd also confirm that comment about Wowza streaming from S3... I've never worked with it, but if you're streaming, chances are S3 is just storage, and you're actually streaming from EC2 (I don't think you can run an application on S3... but maybe I'm wrong there)
    The trouble is, regardless of the software, you're still in competition for bandwidth. There's only so much capacity at the network interface of each shared server, and if you happen to land on a busy server, you may find there isn't enough to go around. For stateless applications like HTTP request/response, that's fine, but for apps that require statefull client/server connections, bandwidth and latency issues can prove catastrophic.
    The biggest problem I have with running a streaming server on EC2 (virtualization issues aside), is that they won't disclose hardware or network specs. So, while you can be sure you'll have the memory and processor allocation, it's a crapshoot when it comes to disk time and bandwidth, as you have no real idea how many other instances you're sharing a server with, or what those other instances are doing in terms of bandwidth and disk usage.
    While I don't know any of the specs on the cloudfront service, I suspect those servers are load balanced in such a way that bandwidth is accounted for. In the general population EC2 servers, that's not the case.
    My advice... really research this before you make your deployment decisions. I've come to find that while scaling out is a bit more challenging, dedicated hardware and bandwidth isn't all that much more expensive than EC2, and when you go dedicated, you can actually count on your resources being available to you.

  • How many video chats can you use with this server?

    I am looking to develop a multi-video chat app that's easy to
    build. Can I use Stratus with this? Or do I need to use FMS.

    none of the video streams will pass through Stratus. Stratus
    only enables end-to-end streams. You are limited only by the amount
    of bandwidth the client ends have as far as how many different
    streams can be flowing.
    if you need to relay streams through a server (the to-many
    case, or the end-to-end is blocked by firewalls or certain NAT
    configurations cases), you'll need to use FMS.

  • 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.

  • How many Voice connections can cisco 2821 support?

    Good day.
    I have a cisco 2821 with EVM slot, NME-X slot and two HWIC slots. I have 4 port FXOs on the two HWIC slots. The EM-HDA-8FXS module on the EVM slot can handle 8 FXS connections. Please i would like to know if there is an EVM module that can do FXO connections and also how many voice connections can this router handle in total. Can the EM-HDA-8FXS module handle both FXS and FXO connections?
    Hope someone can help me out. My deadline has already passed.

  • 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?

  • 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"

  • 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,

    Theoretically as much as you want but there are technical limitations about the usable bandwidth in the wireless or by the used access point.
    All participants (stations) in a wireless network share the available bandwhith equally and therefore a point will get reached where the throughput in the network became insufficient to stream music.
    Also some routers limit the number of stations could get connected. For instance Apples Airport Extreme have a limit of 50 connected clients and the AP-Express (if used as access point) a limit of 10 simultaneous connections.

  • HT204291 Is there a limit to how many AppeTVs I can stream to simultaneously?

    Is there a limit to how many AppeTVs I can stream to simultaneously?

    Stream what? If you mean airplay then you can only send 1 video stream, audio cannot be separated. Music can be sent to different airplay enabled speakers (including those connected to ATV) within iTunes or by using remote app.
