Consider a Linux NAT-gateway on an ADSLlink providing internet for a
number of users, say, 100 or so.
I want to use WRR, perhaps with attached SFQs or similar, to make sure
every user get their fair share of download.
Atop, at the root, I'll place a HTB to limit bandwidth to make sure the
gw is the bottleneck to make shaping efficient.
How do I prioritize packets based on tc filters between the root HTB and
the WRR?
What I imagine is something like:
DEV
|
---------
| HTB | "Bottleneck"
---------
|
|
-------|--------
/ | \
/ | \
/ | \
------- ------- --------
| LOW | | MED | | HIGH | "Prio-bands"
------- ------- -------- (HTB, pfifo_fast, PRIO
\ | / or the like)
\ | /
\ | /
----------------
|
|
-------
| WRR |
-------
|
|
-------|--------
/ | \
/ | \
/ | \
------- ------- -------
| SFQ | | SFQ | | SFQ | x 100
------- ------- -------
I'd like to do that to make sure that the system overall favours
interactive traffic before "bulk". Games and other latency-dependant
traffic types must perform the best on the cost of ftp-download or similar.
Attaching pfifo_fast, PRIO or triple (low/medium/high priorities) HTB
qdiscs to the root is easy but it seems that it is impossible to attach
/one/ WRR afterwards.
How do I accomplish what I want to do?
