Best relation (value) of rate and burst in TBF and HTB
Hi, I''m going to setup a linux traffic control box and has decided to adapt HTB. What should be the best relation(value) of rate and burst? I mean the formula used to calculate burst give rate or vice verse. I think the bandwidth of NIC and CPU processing speed are also important in the calculation above. What else are important?? Thanks a lot, Willim __________________________________________________ Do You Yahoo!? Yahoo!

What else > are important??Rate and burst do not really influence the CPU. The more classes you have, the more load it will give. But I once shaped 5.000 parallel streams on a 10mbit connection with 486, 25hz, 8MB ram. I used htb and the box survived the test without the load becoming bigger then 1.00. If you use latest htb, you only need a rate parameter. The burst will be callulated for you.
