QoS and guaranteed bandwidth

[ovidiue at unixware.ro]

I must have two different values for every user: guaranteed bandwidth and
maximum bandwidth

Citat "Alexandre D." <alexandre.delay at free.fr>:

> The best way to assign guaranteed bandwidth is to play with dummynet.
> 1) you create a pipe for each user defining the bandwidth limit (burst)
> 2) you do not assign more bandwidth than the available bandwidth.
> 
> In fact, the burst is a real value (technical value), while the "guaranteed
> bandwidth" is a theorical value (total guaranteed bandwidth divided by
> number of users).
> For example, if I have 4 users with different burst limits:
> -A: 128k
> -B: 128k
> -C: 256k
> -D: 512k
> 
> In the case of a 1024k total guaranteed bandwidth, the guaranteed bandwidth
> per user would be:
> -A: 128k
> -B: 128k
> -C: 256k
> -D: 512k
> 
> But for 512k, the guaranteed bandwidth per user would be:
> -A: 64k
> -B: 64k
> -C: 128k
> -D: 512k
> 
> You can play to assign more bandwidth per user (for example 64k for user A
> and 128k for user B), but this is a bit more difficult. In this case, you
> must use WFQ (Weighted Fair Queueing).
