Subject: [LARTC] simple traffic shaping problem
Date: Sun, 03 Feb 2002 18:21:43 +0000	[thread overview]
Message-ID: <marc-lartc-101276057903430@msgid-missing> (raw)

Hi All,

I read the advanced networking howto and find a useful way to shape my 
adsl link.

is says:

"tc qdisc add dev ppp0 root tbf rate 220kbit latency 50ms burst 1500

[...]
Change 220kbit to your uplinks *actual* speed, minus a few percent. If 
you have a really fast modem, raise 'burst' a bit. "

My adsl's upload brandwidth is about 120 kbits/sec, download brandwidth 
is about 384 kbits/sec.

So I use

tc qdisc add dev ppp0 root tbf rate 100kbit latency 50ms burst 1500

but after this command upload falls down to ~20-30 kbita/sec average.
as I see in iptraf, the upload speed can reach the needed 100 kbits/sec 
but it 'hangs' very often.

can you help me with the right parameters?

thank you,
