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
