Hello all,
I have browsed archives and real all
available HOWTOs, but I still have a few doubts.
My set up is a router, as below.
LAN(100MB)-------------(eth1)Linux-Router(eth0)---------------WAN(2MB/512)
My aim is to cotrol both uplink and downlink
bandwidth.
For uplink control, I will use HTB on WAN
interface. For downlink, I plan to attach HTB on LAN interface(both
egress/outgoing). No ingress policing, no IMQ.
On WAN interface, like in wondershaper and
myshaper, I plan to have classes which handles interactive and bulk traffic
seperately. ACK packets and small packets also in interactive
class.
This setup guarantees that
a) interactive traffic wont be drowned
out
b) uploads won't slow downloads
But this set up does not guarantee that one bulk
traffic will not drown another bulk traffic, right? For example, FTP traffic
might affect HTTP. If
Am I right?
So I plan to have a downlink control, achieved by
shaping on LAN interface(eth1).My idea is to
filter different protocols into different classes having different rate and
ciel. In this way, I maybe able to ensure that FTP downloads will not slow down
the HTTP traffic too much.
My doubt is, if I do this, will it work well with
the different filtering scheme of uplink(WAN)? i.e, the traffic is controlled in
the uplink and downlink in different ways, one based on protocol(LAN) and the
other based on latency issues(WAN). Will they affect each other? Can
they exist together and give the desired results?
I know it maybe a good idea to test it myself,
hands-on. But I am not able to simulate all the combinations. If my idea is bad
in theory, I do not need to spend too much time on it.
On a different note, why the sum of child classes
in wondershaper is more than its parent? Why it still works?
regards
Salim
