Subject: [LARTC] Question: traffic shaping (tc-htb)
Date: Mon, 30 May 2005 14:39:18 +0000 [thread overview]
Message-ID: <002d01c56525$5d124180$0b00000a@jo> (raw)
Hello *!
My trafficshaping (tc-htb) drops packets very early, at least i suspect
this. It drops about 30% fo the packets. The traffic-generating appication
is running locally on the shaping host. I think i can lower this rate by
increasing the packet-buffer, because the locally application will slow down
with increasing buffer (tcp/ip). But i can´t find any options for that, i
cycled the manual several times. Is there a solution?
see output of "tc -s -d class show dev ppp0" (main class):
class htb 1:10 parent 1:1 prio 1 quantum 1800 rate 144000bit
ceil 480000bit burst 1779b/8 mpu 0b overhead 0b cburst 2199b/8
mpu 0b overhead 0b level 0
Sent 57567157 bytes 40609 pkts (dropped 16033, overlimits 0)
rate 460328bit 40pps
lended: 12845 borrowed: 27764 giants: 0
tokens: -74623 ctokens: -28826
This class is the only one with packet drops. Does tc use the kernels
network packet queue?
Great thanks in advance
Alvo
