Does Queue processing (QoS, PCQ, HTB, etc.) depend on ISP?!!

[dot-bot]

What I’m talking about have been discussed by other members as well:

from Is (( PRIORITY )) Really working ??? topic:

@janisk

create main queue with 100% upload or download respectively. then make child queues,

• • queue for ping, high priority, 1% of traffic
    
    
    
• • queue for http, high priority -1, say, % depending on speed for example 1MB/s and that is 40%
    
    
    
• • queue for the rest of traffic

all that for download, upload

that way, if no one uses ICMP and TCP-HTTP you have 100 - 40 -1 % of your BW used = 59%

then, when you have some “hardcore http surfers” you will use 99% of traffic, and then, if someone start using icmp he will get last 1% for ICMP

…

also - parent queue have to have match all the traffic that will go for child queues

This way we waste bandwidth. Download will achieve only 59% of total link speed. We need to show our customers advantage in speeds and quality, not disabilities.

1 What queue type are you talking about? HTB or PCQ? No text clearly explains when one can be used and when other should not be used. 2 Does queue trees need to have queue-type=default for HTB and queue-type=pcq-up/pcq-down for PCQ? 3 Can I use PCQ and set priority=?? kinda giving priority for some packets over others, while equalising bandiwdth (keeping PCQ functionality). Hoping to minimize delay for prioritized packets (with priority=1). ? 4 Can I build a Queue Tree with leafs and parents having different queue-type?

@samsoft08

YES we can let the side car to enter the road even if its 100% , a police man can stop the side line making a space for this car … right ? this police man what i’m searching for ..

yeah, right. but, as I said, this policeman had to be before the side road, i.e. at your provider’s devices

5 If this policeman is our bandwidth manager in our MT, when he drops packets, tcp flow should adjust in 2-3 seconds due to TCP window adjusting?

@gustkiller

i think if you just do the queue tree and the MAIN QUEUE for upload and the MAIN QUEUE for download for an example 95% of your total down/up bandwitdth the priorities and qos should work better coz they will have some room to work.

6 Maybe QoS should work nevertheless but keeping some spare bandwidth could save us those 2-3 seconds? Allowing for the car to enter the road first, and the policeman dropping another car after he sees there will be no space on the road ahead?

@MyThoughts

…
Another thing to mention is I’ve noticed some internet service providers are already doing their own internal QoS I noticed this on my home internet connection. This made it a bit more difficult as I had no idea what they were in fact doing. So if you are using a generic cable/DSL connection to the internet for your backbone to your wireless network it may be worth asking them if they apply any QoS, or if the modem unit they provided you does.

This is the question of this topic. 7 How does provider queue processing (a.k.a. QoS, shaping, policing, etc) affect the work of our QoS in our MT?

@omega-00

@Equis

I shape Inbound Traffic
The key is to set your upper limit about 15% lower than your service can push.
so if I had 10Mbps from my supplier I would set my top to 9Mbps.
It does work perfect, I light user has 10ms ping, the hog user when he uses torrent gets 1000+ms ping.

This is probably the best idea I’ve seen yet, nowhere near as complicated as shaping outbound pps and makes sense that it allows a margin for any new traffic/connections you can’t control straight up. You do however need a connection that has a set limit (eg this wouldn’t work as well on an contentioned connection as you aren’t guranteed the bandwidth)

Exactly. 8 What about those cases when ISPs give us let’s say 100Mbps town speed tops, 20Mbps country speed tops, 10Mbps Europe speed, 1Mbps world speed in one cable? How will MT PCQ handle this type of service? It looks like we will be forced to set max-limit 1Mbps for speed to be fair, loosing the rest of the bandwidth. Another type of service is when our ISP gives us for example 10Mbps but between 16:30-22:00 limits us to let’s say 5Mbps. How to s setup PCQ then? 9 If we do not set max-speed at tall, what will happen to PCQ?

I hope everyone understands what is talked about here and if anyone has anything at all useful to share here - please tell us. Thank you.

@MikroTik staff: This is a challenge for MT as well so I anticipate your answers to these questions above. And am thankful as well.
