Qos question

[jim trudel]

Hi,

How to know if qos works and know if it's well configured?

I tried it but really not sure.
My tv is wired to my router + I have 2 laptops + 2 smartphones and I would like to be sure that my tv has more bandwidth to stream 4k vs others.

Thanks

What's your internet speed. Anything over a few hundred Mbps you don't need QoS. And it can actually hurt performance.

Even with just 120 Mbps you have enough bandwidth for a couple of 4k streams plus other less data intensive applications.

While you listed what devices connect to your network how many users do you have in your household? A multiple people downloading large files, streaming videos can impact your streaming but if that isn't the case then QoS probably isn't necessary.

Yeah, I agree. I ran (s)low speed DSL at three sites for years and QoS was a proven lifesaver. Now that I have 100 Mbps at all three sites, well, I didn't bother with QoS and everything runs just fine without it.

("If it ain't broke don't fix it" : -)

Now if you have an Asus router take a look at your "Traffic Monitor". Take a look at "real time" while your family is doing their thing. You might be pleasantly surprised by how little is actually being used.

Or check out the "24 hour" graphic to see all the peaks and valleys. Again, you might be pleasantly surprised. (Heck, you'll even be able to see what time the kids went to bed : -)

But that said QoS does work. You set your up and down bandwidth to about 10% less that your actual speeds. Then you set what's important to you to a higher priority, typically interactive stuff like web browsing or VoIP (telephone). For DSL it's a "must". For high speed, well you're probably better off taking advantage of the hardware acceleration that you would lose with QoS. 100 Mbps? You're on the "edge", you could go either way, depends on your actual usage.

I would use QoS in your situation to ensure your TV is “guaranteed” adequate bandwidth. While 120 Mbps is enough for your streaming, you can’t predict what other devices are going to be doing (e.g. downloads, speed tests, gaming, etc.). Depending on what router you’re using, your QoS options will vary. Asus with Merlin let’s you use the FreshJR QoS script which pretty much perfects QoS for most people.

If I put high priority to Netflix (smart tv)
And others less... it means that automatically the bandwidth goes to the tv when it's on function? I would like to know the ratio [emoji848]

Depends on which QoS you use. Some use canned algorithms. Others allow you to use priority "buckets" and to specify % of bandwidth by bucket. If it goes unused it spills over to the next bucket.

If TV is important to you I wouldn't give it a low priority but I wouldn't give it "high" either. Streaming is kinda forgiving, it does buffer such that you can afford to miss a "turn" or two. "Interactive" is typically low bandwidth so if it's high priority it shouldn't impact streaming much. On the other hand if a phone call (VoIP) misses a "turn" due to high priority streaming the call will "stutter".

Interesting point. At work I cannot predict what our users will be doing. At home I can. At least I can until my grandkids become teenagers. At that point I may consider using QoS : -)
