I presently use TBF with this syntax: tc qdisc add dev eth0 parent 1:100 tbf buffer=15000/8 LIMIT=30000 MTU=1500 parent class is a cbq with rate=128Kbit when I want to add PEAK, I get always RTNETLINK error: Invalid argument. Maybe be I don''t understand this parameter. What I know about it, it''s that it can control short-term burst traffic, and it''s what I need to do.

Hi all! I just started to experiment with bandwidth management using tbf. I have the folowing problems with token understanding: 1) What unit is token? Is "1 token = 1 byte" ? If this is so, then with rate=0.5mbit and HZ=100 the bucket gets filled with 0,64kb (655 tokens) every 10ms? 2) How much tokens are used for one packet (1500)? 3) And token unrelated question. Does

Hello all, My company is sharing it''s internet access with a neighbor and the neighbor in question was eating our bandwidth (both in upload and download) most of the time. I finally set up a linux router to limit the incoming/outgoing bandwidth to his network by adding a tbf on eth0 interface and eth1 interface of the router (neighbor is behind eth1 and we are in-between him and the

Hi, I have a basic router that is shaping traffic, and it seems to be working at the moment. We have a 100Mbit connection to the internet, however we get charged for each mbit that we use and so have to shape/limit the traffic to avoid huge bills and my boss getting cross!! We have a /29 subnets set up as follows: tc qdisc add dev eth0 root tbf rate 0.8Mbit latency 50ms burst 10k tc qdisc add

Hello mailing list, i stand bevor a mystery and cannot explain it J. I want to do shaping and prioritization and I have done these following configurations and simulations. I can´t explain, that the combination of PRIO and TBF is much better than the HTB (with the prio parameter) alone or in combination with the SFQ. Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

Hi Everyone.. I started using Tc and iam Newbie.. Iam trying to use simple TBF to drop the excessive traffic than the rate. ******* Scenario: ******* SRC 1,SRC 2 are sending 5MB traffic each to DEST. I have implemented TBF qdisc at Eth0 0f R1 Eth0 of R2 Eth0 & Eth1 of R3 Eth0 0f R4. the TBF applied is tc qdisc add dev eth0 root tbf rate 1mbit burst 5kb latency 350ms. ******** Result

hi i am running Debian/GNU Linux with 2.4.26 kernel and radius server my kernel conf looks like this <*> Packet socket [ ] Packet socket: mmapped IO < > Netlink device emulation [*] Network packet filtering (replaces ipchains) [*] Network packet filtering debugging [ ] Socket Filtering <*> Unix domain sockets [*] TCP/IP networking [*] IP: multicasting [*] IP: advanced

Hi have set the following tbf tc qdisc add dev eth0 root tbf rate 0.5mbit \ burst 5kb latency 70ms peakrate 1mbit \ minburst 1540 I want to add a filter so the ip traffic pass from it.. plz help me __________________________________ Yahoo!

Hello, My company runs several Internet Cafes in Mexico, where bandwith is limited and very costly. We use Linux to do NAT and firewall stuff and at each location we have about 30-40 stations. I''d like to know if anyone out there has any suggestions about how to use CBQ to limit the bandwith at each station. We only have a 128k circuit. The problem I am having is that since I have that

lartc-request,hello! 　　 I find a line in tbf_change() in sch_tbf.c: ptab = xchg(&q->P_tab, ptab); Can I consider that the pointers are exchanged between q->P_tab and ptab? as following: prev=q->R_tab; q->R_tab = rtab; rtab = prev; Is my understanding righ? ======= 2002-03-23 12:01:00 you wrote:======= >Send LARTC mailing list

Hi all! I''m new to this list, and hope for some clarity in this matter: I have a home-gateway with linux-2.6.9 and iproute2 (ver:2.6.9). My following tc syntaxes. # eth0 internet scheduleing are: tc qdisc add dev eth0 root handle 1: htb default 20 tc class add dev eth0 parent 1: classid 1:1 htb rate 512kbit burst 6k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 512kbit burst

I have a setup where I have three NIC in a Debian box. I have eth1 conected to internet and eth0 NAT''ed to 192.168.1.1. eth1 and eth2 are bridged together, given ip 192.168.122.2. What I want to achieve is to perform traffic shaping on the bridge as well as prioritizing the traffic from eth0 very low. (This is from trental flat ...) However it seems that I am unable to perform thhe

Hello all, I am trying to configure a linux box to make some QoS into my netowork and, at the same box, control my clients bandwidth. I have this classes created: ---------------------------------------------------------------- UP="eth0" # wan infocontabil DL01="eth2" # lan clientes $TC qdisc del dev $DL01 root 2> /dev/null >

Hello Please give advice in selecting suitable QoS Solution for our device. It contains one WAN port and a LAN port(4 port switch). The WAN will be connected to an ADSL modem(so we don`t know the bandwidth in advance for the WAN and depends on the ADSL connection taken). We need to give highest priority to the Voice and control the WAN bandwidth to 2Mbps. I tried with the TBF by giving 500kbps

Hiya, i have a squid-2.5.4 transparent proxy working in http accelerator mode (i.e. web servers are behind the squid, and all www records point to the squid IP) and i want to implement some sort of bandwidth management so, for example, any given hosted website/server won''t eat more than let''s say 1Mbit of upstream bandwidth, i have recompiled squid using Patrick Mchardy

Hello all, I have set my QoS solution and now I am facing a little problem... When I ping to my server it has some lost packages: Estatísticas do Ping para 172.30.0.1: Pacotes: SENDED = 1029, RETURNED = 880, LOST = 149 (14% de perda), Aproximar um número redondo de vezes em milissegundos: Mínimo = 0ms, Máximo = 686ms, Média = 105ms If I disable my QoS ping stats to be ok. I even have

Hello all, I am with a doubt about QoS solution... I have a 4 Mbit backbone coming from the telco I use... This is the link I serve to my clients, so I make this classes: $TC qdisc add dev $DL root handle 1: htb default 60 CLASS="/sbin/tc class add dev $DL parent" $CLASS 1: classid 1:1 htb rate 4096Kbit $CLASS 1:1 classid 1:10 htb rate 256Kbit ceil 3072Kbit burst 15k $CLASS 1:1

About the cbq.init. Four machines which traffic to limit in same LAN. Is the samething if I put limiting rules to four different files or all to the same file? Like: DEVICE=eth0,10Mbit,1Mbit RATE=64Kbit WEIGHT=6Kbit PRIO=5 RULE=192.168.0.5 RULE=192.168.0.6 RULE=192.168.0.7 RULE=192.168.0.8 OR four equal files with different IPs, Ids and no PARENT rule? What style of ID numbering you use if

Hi there, i''m trying to shape incoming trafic on my linux box. I want it to depend on the source IP adress of the packets (in fact, i got a VPN on an ADSL link and wanted to get at least/max 64Kbit/s for the VPN) So i tried this : tc qdisc add dev ppp0 root handle 1:0 cbq bandwidth 512Kbit avpkt 1000 cell 8 tc class add dev ppp0 parent 1:0 classid 1:1 cbq bandwidth 512Kbit rate

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.
