UNSOLVED
Dell PowerConnect 2824
We need some help with setting up a 2824 switch to it best performance for use with pubic server like we have a large teamspeak 3 servers we use 10 servers 2 main servers with 5Virtual ts each http://www.teamspeak.com/ and we are finding when we have 200 + people on all the servers we are seeing our 100meg service drop to 30 megs so my isp is saying the the switch is the issue (maybe )voice communication using TeamSpeak 3 what would be the best setting for this we are not using phone all web base we are a nonprofit community we need everyone help with this issue i am not sure what the best.. is the 2824 good for this or do we need some better thanks
well we are seeing that the cpu at 79% with update we feel the this switch can't handle 200+traffic we are seeing a lot dropped (connection lost) on our servers when it hit this and it drops our download speed to 30 to 18 meg from105meg.. if i turn off server 2 teamspeak it puts the speed back to 105meg down this cuts off 100 +people for a min is this switch able to handle 200 to 500 traffic load or do we need a better switch we own 3 of these switch we feel great switch for small use but not good for large traffic loads what do you thing 6224 or a 5524 would in prove this or will the 2824 work and we need a Web-base Managed Switch thanks once more for your help
we test and seem to be no improvement still seeing a drop to in the 30mbs download speeds from 100mbs when we have a good amount of people on (200) we are going to try the 6224 switch and see if it the switch capacity issue loading it down if you have any more ideas let us know thanks

bandwidth does TeamSpeak require?
how many people will speak at the same time for how long makes is nearly
impossible to give a detailed result of how much bandwidth and traffic is
required.
Basics:
- Each person speaking sends one voice stream to the server
- The server decides based on who's in the same channel to whom the stream has
- If 12 persons in the same channel speak at the same time, the server
- The server does not mix the voice streams.
- The server sends a heartbeat packet (66 Bytes) to each client each second
The bandwidth and trafficto be sent.
receives 12 voice streams and sends 12 voice streams to every one in the same
channel.
which answers with a packet (62 Bytes).
requirement is depending on:
- The amount of channels and users
- Selected codec in the channels
- People speaking at the same time in same/different channel
- The server's uptime
This FAQ can only show you how you cancalculate the bandwidth/traffic requirement for your server as only you know
your specific setup and how often and how long people will talk on your
server.
Bandwidth calculation for the server
We'll
divide this into several examples which hopeful explain the calculation somewhat
better. The first is a simple example we'll explain a little bit more in detail.
For each example we use the following syntax:
DOWN:people_speaking_atm * selected_codec
UP: people_speaking_atm *(people_in_channel - 1) * selected_codec
The following would be a
server with one channel set to Speex 25.9, 10 people in the only channel and one
person is speaking:
DOWN: 1 * 25.9 Kbit/s = 25.9Kbit/s
UP: 1 * (10 - 1) * 25.9 Kbit/s = 233.1Kbit/s
As you see in this example, the DOWN bandwidth is usually
not a problem but the UP bandwidth can be one - especially with home Internet
access as they usually have asymmetric bandwidth where the DOWN bandwidth is
much higher then the UP bandwidth.
Here's another example with one
channel set to Speex 12.3, 10 people in the only channel and two persons are
speaking:
DOWN: 1 * 12.3 Kbit/s = 12.3 Kbit/sUP: 2* (10 - 1) * 12.3 Kbit/s = 221.4 Kbit/s
The last example shows how
the bandwidth requirement explodes when more then one people are speaking at the
same time. In TeamSpeak 2 there is no setting to stop simultaneous
speaking.
Client bandwidth calculation
Lets look at
the bandwidth requirement for the client. We'll explain this by looking at the
two examples above. UP and DOWN bandwidth are now contrary when looking at the
client. We always assume that the client we are looking at is the one or one of
the speaking person. If he is listening, there is only DOWN bandwidth
required.
DOWN: 0 * 12.3 Kbit/s = 0 Kbit/sUP: 1 *12.3 Kbit/s = 12.3 Kbit/s
DOWN: 2 * 12.3 Kbit/s = 24.6Kbit/s
UP: 1 * 12.3 Kbit/s = 12.3 Kbit/sBandwidth
requirement for the client are usually not a big issue, unless you're in a Speex
25.9 channel with an analog Internet access. But when hosting a server at home,
you have to be aware, that especially the UP bandwidth is the limiting
factor.
Keep in mind, that a game or other application
you run in parallel to TeamSpeak requires as well bandwidth and with several
open connections you can not use 100% of your bandwidth. The connection quality
will decrease which will be easily heard in a time sensitive application such as
a voice-communication tool.
