Hi, Actually, I did some modification on sch_fifo.c to do some required accumulation of packets lets say 300 packet and to dequeue them together but I couldn''t compile the modified fifo, the question is How can I compile and to test my modified fifo.

Hi all I am conducting the experiments comparing IP router forwarding delay and MPLS LSR forwarding delay, it is obvious in theory MPLS in Core should be faster than IP, but for small netork (only have several core routers), result show it is not, this is why I want emulate a large IP routing table in one core router. can I do it and how ? right now I use static routing table (by using command :

tc class add dev $DEV parent 1: classid 1:1 htb rate ${UPLINK}kbit burst 6k tc qdisc add dev $DEV handle ffff: ingress tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \ 0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1 why does the download is being sent to class 1 which is limited by uplink ? why the rate is being mentioned in filter and in class ?

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

Hi, I have a parent class 1:1 with rate=ceil=64kbit i create 3 classes under it(1:1). class 1:2 rate=ceil=32kbit class 1:3 rate=ceil=16kbit class 1:4 rate=ceil=16kbit if 64kbit traffic is flowing from the cable all the 3 classes will get their respective shape. 1 .if only 32kbit data is flowing(for some reason). a. Then how will the traffic gets distributed.? b. Is it in first come first serve

For simplicity, I tried this: tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:1 handle 10: sfq perturb 10 tc qdisc add dev eth0 parent 1:2 handle 20: sfq perturb 10 tc qdisc add dev eth0 parent 1:3 handle 30: sfq perturb 10 tc filter add dev eth0 protocol ip parent 1: prio 2 flowid 1:1 The last line prints: Unknown filter "flowid", hence option "1:1"

I''m trying to setup a netem delay with no luck (using iproute2-2.6.8, compilation broke during arpd compile, so I use the tc binary in the tc/ subdir, there''s also a q_netem.so there). kernel is 2.6.8.1, compile with CPU cycle counter as time reference. I was using sch_delay of 2.6.7 happily with something like: tc qdisc add dev eth0 root 1: delay latency 1ms rate 35M now I use:

Hi! I had two uplinks till today. We stopped one of them today, so i thought i could share my experience. (it is maybe useful for somebody) I hadn''t managed to configure it using a LARTC howto, but the Nano-howto (http://www.ssi.bg/~ja/nano.txt) and julian''s kernel patches. I had some problems with icq connections, because it is a two step connection (It is just theory). 1.

Hi, my name is Grant Taylor. I am a subscriber to the LARTC mail list lartc@mailman.ds9a.nl. The LARTC mail lists has been plagued with viral email coming from changing IPs in your one of your subnets. Based on the fact that the WhoIs information below says that the subnet in question is a dial up pool this would explain the changing IPs. In less than 6 days the list has received 14 viral

Hi folks I have created a script file (dsmark+policing.sh attached) to check graphic an text outputs of simutations, against original examples/dsmark+policing coding (see TCNG Reference Manual-pg.90). It uses tcng coding (*.tcsim file attached) and old tc coding (*.tcsim_old file attached) inserted in tcsim files. Observation 1: The graphic outputs from (*.tc included in *.tcsim) and (*.tc_old

... do not work anymore. Anybody with a hint? I''ve got a fully functional HTB setup and just wanted to replace the kernel from 2.4.17 to 2.4.19. In the end the modified tc binary doesn''t recognize "tc filter add" (yet it does accept qdisc show and recognizes htb...) I''ve downloaded the 2.4.19 from kernel.org, iproute2 (2.4.7), installed the patches

Hey Marek, I´know that i must to works whith the INGRESS (instead of EGRESS), i´ve well formed my kernel. My others TC rules for source IP address (not for MAC address) does work fine...!!!, the problem is whith the MAC because is a not "IP PROTOCOL" and for that i must to use the "u32/u16 match" to solve it, and if i make an analogy from my others INGRESS rules applied to Src

Hi, I think you now have 2 Links to the internet. You want to route web traffic (transparent proxy triffic) via one link and the rest via the other link. If it is the case, It is possible to do. I have done it. here I have mentioned eth0 and eth1 eth0 is connected to one link (link1) eth1 is connected to other link (link2) , via this link, web traffic will be routed. echo 210 link1 >>

Hi Andreas! I mainly understand what you mean, but best for me would be if you could make an example from the script I have. I know I did something wrong into it, but I still can''t see the error. If you could fix the error from my script that would be much appreciated. Looking forward to hear from you, Daniel Phlander lartc-request@mailman.ds9a.nl wrote: Send LARTC mailing list
