[LARTC] Simulating 256k Link Using CBQ or HTB

[LARTC] Simulating 256k Link Using CBQ or HTB

[Shaun Cronin]

Hi All,

I've been asked to provide a QA setup in which one W2K server must only 
communicate with the rest of the network at a speed of 256 or 512k (to simulate 
and external link)

My idea is to place a Linux box with two NICs between the server in question 
and the rest of the network and use it to control bandwidth.

With Kernel 2.2 it seems that rshaper would work but reading Linux 2.4 Advanced 
Routing How-To is leading me to think that CBQ might be the answer. 

Now I see that there HTB may be prefered to CBQ.

So in trying to work out the correct tree to bark up, any ideas whether the my 
idea would work and which method HTB/CBQ would be the best?

Thanks,

Shaun

If you are just using ethernets, you can probably get away with CBQ with TBF
internally. See the excellent cbq.init tool mentioned in the HOWTO.
