The trick is to signal looming So based on @moeller0's post and the fact that it maps well to both Wifi WMM queues, and the queues on cheap TP-Link managed switches, you should probably switch to CS6 for highest priority, CS3 for mid priority, CS0 for normal priority, and CS1 for bulk. According to the OpenWRT documentation, dnsmasq, firewall, and dhcp should be disabled. So now I added a OpenVPN (tun0) connection (Hopefully properly) and sending the OpenWRT Users: Recommended SQM/CAKE Settings? 📶 Starlink Speed Fellow Starlink Testers: As a long time WISP user (survivor?), I've been using CAKE for fair and minimal-bloat congestion control on our network. The working configurations immediately and obviously reduce bufferbloat and correctly limit The best strategy is not to install SQM on the wifi interfaces, but to DSCP tag high priority packets, in which case the WMM queues will reduce the latency for important packets.

I switched back from fireqos to SQM, because my router (TP-LINK W8970) have low power to handle fireqos config. qos but not with piece_of_cake. 5 r11257-5090152ae3 / LuCI openwrt-19. But I need to enable PBR to allow Netflix and Amazon Prime traffic to bypass WireGuard through the WAN interface. 8. If you're on a Debian-derived distribution that I switched back from fireqos to SQM, because my router (TP-LINK W8970) have low power to handle fireqos config. SQM Struggle Continues. I know that cake supports layer_cake and piece_of_cake scripts. FriendlyElec would be direct from manufacturer. It is there to copy the previously set DSCP value to all # corresponding egress packets and thus eliminate the requirement for each # packet to pass through the 'hard' ruleset. sh 12: veth0@veth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000 13: veth1@veth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc noqueue master br root@OpenWrt1er-router:~# service cake-qos-simple download qdisc cake 800c: root refcnt 2 bandwidth 4Mbit diffserv4 dual-dsthost nonat nowash ingress no-ack-filter split-gso rtt 100ms noatm overhead 38 Sent 15121193 bytes 20638 pkt (dropped 658, overlimits 17755 requeues 0) backlog 0b 0p requeues 0 memory used: 129336b of 4Mb capacity estimate: Why have u made two config. 05. cake doesn't have to set dscp/marks itself, it can put the traffic directly in the right tin with its own internal functions. 7.

This seems to work well for the case that all traffic is sent through the WireGuard interface. also it's better idea to control both bufferbloat + doing prioritization using a AIO solution. 2 install of OpenWRT. I have downloaded the package on github : you need to propetly assign dscp marks before sqm gets hold of the packets, and especially for ingress traffic that is a bit of a challenge. I'm doing 4g over tethering on a RPI4. This should be used in conjunction with layer-cake SQM queue with ctinfo configured to restore DSCP on the device ingress. OpenWrt Forum Extra arguments (in port forward. Then adjust the values in the file to your environment, setting at least UPLINK, DOWNLINK, and possibly SCRIPT. 0 subnet and stays in the switches, where it can max out the switching bandwidth without a big root@OpenWrt:~# cat /etc/config/sqm config queue 'eth1' option interface 'eth1' option qdisc 'cake' option script 'piece_of_cake.

Hello I need some help 🙂 This is my setup: Vodafone Station Cable (Bridge Mode) into NanoPi R4S with OpenWrt 22. ) My setup: I Hi Everyone, New to setting up on how to create dscp marking on specific mac address or potentially a port? This is just outgoing. and I would say 60% elan 40% dscpclassify. Current settings root@OpenWrt:~# cat /etc/config/sqm co My computer is wired to my router, a TP-Link Archer C60 v2 with OpenWrt 19. I play fps (mainly valorant) a lot so having latency is important. Both can do cake SQM at 1400+Mbps. 07 branch git-20. 236 and anything can go to bulk. With SQM off, I average somewhere around 42Mbit/s down and 9. That's still 58k packets a second to do firewall, NAT, and QoS. R6S - Can do cake SQM up to 1500 Mbps (w/ performance tweak). Hi If i use extra arguments in port forward does this applies before custom rules in iptables? The only time you'd do POSTROUTING is if you want to use the incoming DSCP values for something route-wise before you overwrite them. I have been following this thread and a few others older threads in order to try understanding the use of DSCP marks with Cake SQM. Smart Queue Management (SQM) is our name for an intelligent combination of better packet scheduling (flow queueing) techniques along with with active queue length management (AQM). If you have a wired only router you can put SQM on your wired LAN interface with its egress rate equal to your download speed, and don't put anything on the download direction for your WAN. I set up sqm-scripts with fq_codel and simple. 06. Installing and Using OpenWrt. If you want to do the work, you can read the full description at the QoS HOWTO I've installed SQM and what I'm trying to do is classify manually the packets by marking them with DSCP marks. @Hudra @dlakelan @choppyc config queue option enabled '1' option interface 'eth1' option download '750000' option upload '750000' option debug_logging '0' option verbosity '5' option qdisc 'cake' option script 'layer_cake. qos, but override certain things by hand in the configuration file, notably: (DSCP AF33) iptables -t mangle -A FORWARD -o eth0 -p udp -m mac --mac-source 192. 0-1 installed and I'm also able to install the packages which you mentioned above. Bear in mind I do not use PPPoE. 4ghz wifi being outputted, and I am running wired on it. When I'm the only one using the internet, the connection is rock solid in terms of latency (31ms with zero jitter on League of Legends). When I implemented CAKE, it was transformative - suddenly multiple conference calls could coexist with large downloads. What am I missing to get DSCP markings working on ingress? Hey guys, passively reading for some time, I encounter some problems/weird behaviours. It would need to be adapted for however DSCP is being stored in the Installing and Using OpenWrt. I have a WISP that provides me with 50Mbit/s down and 10Mbit/s up. 650 up). My contracted ISP speed is 1. A Xiaomi Redmi AX6 is serving as wireless AP. 63033-62ed4e6.

I I think the problem is in iptables the rate estimate is not on a per flow basis, but in nft it could be done because nft I switched back from fireqos to SQM, because my router (TP-LINK W8970) have low power to handle fireqos config. dlakelan November 27, 2018, hello everyone i want to give my console priority over all other devices on network I've read about tagging my console traffic with dscp and give all other traffic another dscp then let sqm / layer cake handle it used luci to do all the things above but I've read that i must use veth because I'm using wifi (5ghz) for console and 2. But WFQ is not HTB nor HFSC, and Codel is not as good as FQ_C. 5 PPPoE WAN Connection: 20 Mbps download, 20 Mbps upload. Let me try and reiterate. BUT I am also a lazy person and hence will accept a bit more slack im my QoS setup than gamers in general, if it saves me the tedious work of designing heuristic rules and (even worse) maintaining those rules (aka check continuously whether the employed heuristics still work as intended). On inbound from the internet, restore the connmark and then DSCP tag connections that have the connmark so you get the same DSCP tag on inbound packets. This person is also trying to get SQM working with PPPoE. These are the options I use, from the written config file /etc/config/sqm. They do NOT use this file. hello, i want to setup openwrt specifcly for gaming (fps) my ping is 100ms is there a good qos (not sqm) made specifcly for gaming I switched back from fireqos to SQM, because my router (TP-LINK W8970) have low power to handle fireqos config. config queue 'wan' option ingress_ecn 'ECN' option egress_ecn 'ECN' option enabled '1' option debug_logging '0' option verbosity '5' option qdisc 'cake' option qdisc_advanced '1' option qdisc_really_really_advanced '1' option squash_dscp '0' option My SQM is not squashing DSCP. root@OpenWrt:~# tc -s qdisc qdisc noqueue 0: dev lo root refcnt 2 Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 qdisc fq_codel 0: dev eth0 root refcnt 2 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 4Mb my SQM settings. My vision for it was it would (and did!) do a great job on managing interfaces running at a 10 or 100Mbit, and otherwise Just to preface, my current setup is a bridged modem/router to a Dynalink WRX36 as the actual router. I set up Qos in order to mitigate Bufferbloat, I'm getting A+ as a result but I would like to do something more to help myself get better hit reg in some fps. I have a ftth fiber connection with 200d and 100u, using a ONT from my ISP and a Linksys3200acm with openwrt. Piece of Cake seems to put less stress on the router, but seems to do this "ramping up Layer cake vs piece of cake, what is better? If I use piece of cake do I need to use the wash command in the upload? In layers cake, does sqm automatically mark packages or do I need to configure it manually? Which one is the best? diffserv3, diffserv4 or diffserv8.

Obviously the traffic is already tagged as I use SQM on my home router. Copy /etc/sqm/default. So the main issue I am facing with is rubber-banding/latency issues in video games. Here is the latest DSCP marking script, you can name it DSCP. conntrack only script: IPT="iptables" tc qdisc add dev wlan0 root mq #enable multi queue on wlan0 ## set up a 2 pair of veth devices to handle inbound and outbound traffic ip link show | grep veth0 || ip link add type veth ## get new veth interfaces up ip link set veth0 up ip link set veth1 up ## trun on Squash DSCP on inbound packets (ingress): SQUASH. SQM works by properly managing the queue of packets waiting to be sent out. dscp: string : no (none) Packets matching this, belong to the bucket defined in target : direction: string : no If you check cFosSpeed, they will teach you how to configure an ICS just to emulate something similar to what SQM does in your router. Yepp, as expected, it is not cake that screws things up, maybe the DOCSIS plant is unhappy to see DSCP tagged ICMP packets? I note I get less ICMP echorequest variations from the other side of the atlantic: computer:~ user$ mtr -ezbw -c 100 172. Network and Wireless Configuration.
