Bandwidth control


Hi all,

Can anyone help me ?

We have a 2 Mbit DSL, a 16 IP subnet routed on a linux server and there are a 3 Servers, a NAT-Router and 2 Clients

Now it shoud work so, that the 3 Servers have a higher priority and should able to use most of the bandwidth (~85%) when anyone connect to one of them (each server shoud get same speed when more connections one diverent servers) and the clients should only get the left speed (~15%)

but whem there are no connections to the servers the clients (NAT and direct) should be able to use the full speed - 10% (to left a minimum bandwidth to be fast enough for incoming connections to the servers)

is it possible to realize this with linux, and how can I get it to work ??

best thanks for your help

Christoph Krikl

errrmmm... don't know what's in it, and whether it can help you do what you've described but there is a bandwidth limiting howto on the ldp pages:

Good luck, reetep.

thx

thx but I still know this howto and the way with CBQ but so it is only possible to limit the bandwidth to a solid value and not temporery when anyone connect to a server

I'm not sure what you mean by solid value, but the situation you described in your first post is completely doable using CBQ.
I'd make two main classes: one for servers (with guaranteed 85% of the bandwitch) and clients (min 15%, ceil 90%). Then second level classes would divide bandwith between servers. It's also a good idea to do the same for users.
