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.                

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/articles/hfsc.en/

 

bye

Simo

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:

 

                 -------------                         ------------
---------

                |    ADSL     | <----------> |   LINUX  |  <----------> |
LAN   |

                 -------------                         ------------
---------

 

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
