search for: peakrate

Hi, Can you please explain to me the difference between rate and peakrate, in conjucture to TBF. IMHO, rate : controls the no. of pkts flowing through the pipe, and peakrate : controls the no. of tokens flowing through the bucket. A funtion(?) of peakrate and mtu is rate. If this is true, why do I need to specify both peakrate and rate? Regards, suraj. ______________...

...because the delay is so great that things are getting thrown away by the kernel? Could I munge the packets to turn up the TTL or something similar? Many thanks for some excellent tools.

...How much tokens are used for one packet (1500)? 3) And token unrelated question. Does packet droping alway ocurrs or it happens because of bad settings? I have applied this settings on 10mbit ethernet card: tc qdisc add dev eth1 root tbf rate 0.5mbit burst 5kb latency 70ms / peakrate 1mbit minburst 1540 Result: qdisc tbf 8007: dev eth1 rate 512Kbit burst 5Kb/8 mpu 0b peakrate 1Mbit mtu 1539b/8 mpu 0b lat 68.4ms Sent 1284481 bytes 852 pkts (dropped 48, overlimits 1743) Thanks! _______________________________________________ LARTC mailing list / LARTC@mailman....

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!

...it packet should be delayed for 1 second on a 5000bit link) Problem 3: Is it possible to stop the flow of data when the simulated link is unavailable - whilst still keeping a queue of packets The tc command line I am using is tc qdisc add dev eth0 root tbf rate 5kbit burst 0.01kbit limit 50kbit peakrate 5kbit minburst 500 and to simulate a temporary link loss I use tc qdisc change dev eth0 root tbf rate 0.001kbit burst 0.01kbit limit 50kbit peakrate 5kbit minburst 500 Any help would be much appreciated. -- Nick Howden - Senior IT Analyst QinetiQ Trusted Information Management Woodward Bu...

...probably I get something around 620ms. Note that if I configure the "limit" parameter instead of "latency", I can manage to reach values closer to what I need (e.g. 500ms). Is there something I''m missing about latency configuration? 3. I''ve tried to configure peakrate/minburst, but I had to struggle a bit to have them work. In particular, when I tried to set minburst equal to interface MTU (100 bytes, ethernet) as suggested in the manpage I did not even manage to set up an HTTP session. I had to configure a minburst equal to around 12000 to have some traffic pas...

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the
