[LARTC] Shaping the sum of incoming and outgoing traffic

[Jan Rovner]

Hello,

does anyone have a working solution for the shaping both incoming and
outgoing traffic in such
way, that for a given client the *sum* of incoming and outgoing traffic
is somehow defined?

My ISP does the same thing, it gives me just a line of a defined rate,
no matter the traffic
direction (i.e. here is your line, the clock speed is 1024kbps, do what
you want).

I'm a litte bit familiar with HTB, my download shaping works fine.
However, I would like shape
both incoming+outgoing traffic in a way that the sum of actual outgoing
and incoming rates=20
of all my clients would be always below the ISP's line speed in order to
shaping get working.

In other words, I would like to split the ISP's line into a bunch of
hierarchical "virtual" lines
with traffic borrowing etc. like HTB does for download, but with defined
*total* rates (i.e. dear
customer, here is your 128kbps line, do what you want).

What can I do with HTB is to shape incoming and traffic separately
(somehow to virtually split=20
the line for upload/download with limited speeds), but this is not the
way I would like it to be, since=20
would like to get the line used as effective as possible.

Maybe something like IMQ would work, but unfortunately I have found no
example for
that solution.

Any ideas?
