Understanding How QoS works.

Hi,

I have some questions about Download Equalizer - Upload Optimizer options of QoS.

Let me explain our network first. we have total of 20 mbps total bandwidth. Main unit uses10 mbps is wich is on TRUST interface. There are two other units, 5 mbps each. Say LAN2 and LAN3 interfaces. And There is EXTERNAL interface witch is connected to internet. Main unit has heavy internet usage in work hours (08:00-17:00) and needs some QoS love.

If I understand correctly, Download Equalizer and Upload Optimizer are for this purpose; when the specified bandwidth is full, astaro drops the most bandwidth consuming streams packages and processes the new comming packages. Thus it prevents a few users to eat all bandwidth and make the others can't use internet.

I also understand it calculates when the bandwidth is full via Downlink kbit/sec: and Uplink kbit/sec: options.

There the problem comes. What should I set to the Downlink kbit/sec: and Uplink kbit/sec: options? If I set 100 mbps which is internal lan speed, astaro will not drop packages when the internet usage exceeds 10 mbps as it will calculate on 100mbps. If I set them to 10 mbps wont our local file transfers affected and we will not use local 100mbps bandwidht?

You can say set QoS on the EXTERNAL interface but the other LAN1 and LAN2 interfaces internet usage are very low at work hours. So if I set 20 mbps it will also not work as the traffic will never reach that level at work hours and astaro will not try to QoS when the traffic is about 10 mbps.

Hope you get what I am asking. Sorry if its confusing to you.

Thanks

This entire scenario strikes me as odd, but who am I to criticise. [:)] I think you should be able to achieve the desired result by creating three bandwidth selectors:

Name:		TRUST traffic

Selector Type:	Selector

Source:		TRUST (Network)

Service:	Any

Destination:	Internet



Name:		LAN2 traffic

Selector Type:	Selector

Source:		LAN2 (Network)

Service:	Any

Destination:	Internet



Name:		LAN3 traffic

Selector Type:	Selector

Source:		LAN3 (Network)

Service:	Any

Destination:	Internet

and three bandwidth pools, all bound to your EXTERNAL interface:

Name:			TRUST pool

Interface:		EXTERNAL

Position:		1

Bandwidth (kbit/s):	10000

[V] Specify upper bandwidth limit

Limit (kbit/s):		10000

Traffic selectors

[V] TRUST Traffic



Name:			LAN2 pool

Interface:		EXTERNAL

Position:		2

Bandwidth (kbit/s):	5000

[V] Specify upper bandwidth limit

Limit (kbit/s):		5000

Traffic selectors

[V] LAN2 Traffic



Name:			LAN3 pool

Interface:		EXTERNAL

Position:		3

Bandwidth (kbit/s):	5000

[V] Specify upper bandwidth limit

Limit (kbit/s):		5000

Traffic selectors

[V] LAN3 Traffic

You may have to juggle the numbers a bit, but I believe that should achieve what (I think) you're after.
