HI = Simo,

Thanks for the = info. Very interesting read. I forgot to mention in the post that I am still relatively new to traffic shaping with Linux but was still able to more = than comprehend the info in that document. Many thanks = again.

One thing that I am = slightly uncertain of though is that I would prefer not to divide the bandwidth = between x amount of people but rather designate a priority that packets take = over each other which that info doesn’t cover. Is it still possible = using HFSC to accomplish this?

Kind = regards,

Rangi

Hi = Rangi,

Bandwidth ist = important, but VoIP needs more than this. Voice traffic needs low latency of packets. That’s why traffic shaping maybe not lose your problem. &= nbsp;

in this a HFCS = queuing descipline is used instead of HTB, because this can separate between bandwidth and = delay. For more Information about this can you find here: http://linux-ip.net/articl= es/hfsc.en/

Betreff: [LARTC] Traffic Shaping

Dear List,

I am wanting to perform some traffic shaping as the = subject of this email suggests.

What I am wanting to do is this; I would like = to have traffic shaping performed on the following protocols: HTTP, RDP, = GRE, PPTP, SIP and IAX. Obviously I would like to have highest priority = set for voice packets so much so that the general http traffic does not = impede on the voice packets. I would like to have ample bandwidth available = for RDP so that I am able to connect to a remote site and not have too much lag = but ample enough that most tasks can be done. HTTP traffic would = possibly have the lowest priority of all the protocols that I have listed. = So to clarify priority would be something such as this:

1.       = IAX

2.       = SIP

3.       = GRE

4.       = PPTP

5.       = RDP

6.       = HTTP

I have a linux gateway that I will use for = performing the traffic shaping and is setup in the following way:

         &= nbsp;      -------------         =             &= nbsp;   ------------          &= nbsp;           &n= bsp;    ---------

         &= nbsp;      |    ADSL     | <----------> |   LINUX | <----------> | LAN   |

         &= nbsp;       -------------          =             &= nbsp; ------------          &= nbsp;           &n= bsp;    ---------

I plan to have the ADSL router forward all traffic = to the linux gateway using something similar to a BIMAP rule where all incoming = and outgoing traffic is made to appear to come from the public IP = address. I welcome any and all suggestions but would possibly prefer the most = elegant of solutions J

Many thanks in advance

Rangi
