From: Santiago [EMAIL PROTECTED] If you have for example 1024 Kbps, you have to create a class (maybe htb) about 920Kpbs to create the queue. Then you have to attach the prio qdisc to this class, mark the voip packets and send to class :1 in the prio qdisc. That's what I am talking about.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all, I made some filters on tc to match the VoIP traffic based on RTP packet RFC 1889. The only patern I found was the rtp version and the payload type wich identify the codec. The u32 rules are: - - match ip protocol 0x11 0xff - UDP - - match u8

Thanks for the tips Brian, Actually, I have many sorts of links, line PPOE ADSL, PPPOA ADSL which a use PPTP over PPOA relay, radio links that connect in the ethernet interface and cable modems. To change the SFQ queue size I must recompile de kernel? I think a saw some messages talking

Hi, the hint from Martin A Brown which I am experimenting without regret yet is that you shoul decrease the queue lenght to say 30 from the default 100 and also reduce the MTU(MAX. TRANSFER UNIT) to the size of typical voice traffic say 256 using ip link set dev eth0 qlen 30 ip link set dev eth0

Hi all, I would like to prioritise all VoIP traffic on a linux router. I am new to QoS, tc and TOS, to please be gentle. My logic works like this: 1) identify the VoIP packets 2) mark packets using iptables (with TOS?) 3) use tc to prioritise the marked packets. Is this logic correct? If not,
