QoS with latest Merlin FW on AC68U -- OneDrive sync

[pmosher441]

I've got Adaptive QoS enabled on my AC68U with 378.51 Merlin. My main objective in using this is to ensure that VoIP traffic is given priority over streaming and file up/downloading. The main source of upload traffic isn't torrents, but rather OneDrive syncing, which can occur frequently because I have my main photo database of over 45,000 pictures on OneDrive.

I've observed that the upload syncing can more or less saturate my outbound bandwidth (about 7Mbps). It shows in the Traffic Analyzer as the "app" SSL/TLS, I guess because OneDrive traffic is encrypted. Which of the Adaptive Types on the configuration page is this type of traffic included in -- File Transferring? It's not clear to me how to ensure that this sync traffic isn't given priority over VoIP.

Thanks -- Pauline

If the adaptive QoS is a layer-7/application-level firewall, encryption renders it practically useless.

Does the OneDrive Sync use a particular destination port?

Can you allocate all generic/unknown traffic into a lower priority than VOIP?

If you have known, common traffic types, standard QoS may be a better choice.

I think this is a good point. I don't know what ports are used by OneDrive, but rather than try to figure that out, I've changed to standard QoS from adaptive, and simply prioritized all traffic from the VoIP adapter as "highest." Fortunately, VoIP doesn't really use a lot of bandwidth, although voice quality depends on having no delays in getting what it needs.

Thanks for the suggestion.

I have been tasked to benchmark and write a config note on the 68. I use a 66 to the 68 via media bridge. I have 4 VoIP polycoms, 1 Wyse P25 Thin client, HP 6500+ and my personal PC tied to the 66. I started with Adaptive and found my SOAK test with Jitter and Latency as high as 1200 ms up and down. Setting my limits in QoS as the full bandwidth down and full bandwidth up helped nothing. I have a SOAK test running in the back ground emulating 5 G729 calls 24/7 I had set Adaptive to have VoIP first, web browsing 2nd, video 3rd and file 4th etc etc giving VoIP the highest.

Though I experienced no lose of Voice Quality the SOAK test was showing huge problems on the back bone. I ran the 68 yesterday with no QoS and it ran in the 0 - 20ms jitter and latency and this is streaming a baseball game, listening to pandora, testing phones running the VoIP SOAK test and doing my normal day work with no Voice degridation. Why do I mention this?

IMO Adaptive sucks, it is best to use traditional as I wil be testing that tomorrow as I write up my port configs today and implement tomorrow.... More wil be revealed

AT best use Traditional or do not use QoS at all it seems to me that so far Asus does a pretty damn good job without it.

How did your testing with Traditional mode go? I've also seen high latency when QOS is enabled.

It was flawless. IN both Asus-Merlin and AsusWRT. I even cranked up the VoIP test to include 50 G729 Calls on a 50/5 pipe I reduced up stream by 50% and still no degradation.
