I am using tbf to do bandwidth limitation. i found that when i start passing traffic there is a burst and then the rate goes down to what is configured. is this a known issue or do i need to change some parameters? thanks. --------------------------------- Do you Yahoo!?

Hello. I am wondering if the default (auto-computed) burst and cburst parameters are appropriate values for my application. I have a 100 mbit interface which is connected to a 16 mbit uplink. I am sharing this bandwidth into a set of partitions (tc classes) defined as follows: root class [1:1]...

All: Does anyone know what the burst and cburst parameter do? My understanding so far: * I see a lot of different definitions on the web. It seems like burst is the number of bytes sent before serving other queues/classes. So if burst was 1000 bytes and class rate was 100kibit per second. It would send 1000 bytes each time the scheduler...

Hello to everybody, We want integrate in a router/firewall (Debian Based, 2.6 Kernel), an HTB shaper. The goal is to divide the traffic for classes of workstations, at example in three classes, let say A, B and C. Example: A 70 Mb/s B 20 Mb/s C 10 Mb/s If B don''t make traffic, 7/8 of 20Mb/s must be assigned to A and all the rest at B We have used CBQ and HTB, with poor succes. Anybody

Hi! I built some rules to shape traffic from my linux router in both dirrections: to the Internet and to the LAN. When i apply the rules my computer cannot acces the Internet or the LAN. Is this behavior normal? Do I need to write some rules for local IPs of my router? (I have sevaral, both on the internal and the external NICs.) Thank you for any advice! Sorin.

Hi all :) If I set the burst/cburst parameter to, let''s say, 1500, the command "tc -s -d class show dev eth0" says that the value is 1499b/8 instead of the (correct?) 1500b/8. Is this right or am I doing anything wrong? Many thanks in advance :) Raúl Núñez de Arenas Coronado -- Linux Registered Use...
