X-BeenThere: codel@lists.bufferbloat.net X-Mailman-Version: 2.1.13 Precedence: list List-Id: CoDel AQM discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 24 Jun 2014 17:55:06 -0000 --=-5/UVaXvglIdt+RW0hyqK Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi all, I've upgraded my router to OpenWRT Breaker Barrier r41163 which has kernel 3.10.36 in it. I was pleased to see that codel appears (to my very newbie eyes) to be default on what should be the "fast->slow" (where bufferbloat happens) interfaces: qdisc fq_codel 0: dev eth0 root refcnt 2 limit 1024p flows 1024 quantum 300= target 5.0ms interval 100.0ms ecn=20 qdisc mq 0: dev wlan1 root=20 qdisc mq 0: dev wlan0 root=20 qdisc fq_codel 0: dev pppoe-wan1 root refcnt 2 limit 1024p flows 1024 quant= um 300 target 5.0ms interval 100.0ms ecn=20 qdisc fq_codel 0: dev tun0 root refcnt 2 limit 1024p flows 1024 quantum 300= target 5.0ms interval 100.0ms ecn=20 So first thing to notice is that this router has two WAN interfaces but only one of them (pppoe-wan1) has had codel applied. The other WAN interface (eth0.2) is not even listed. So off I go to experiment with the WAN interface that does have codel applied... So I do the saturate-and-ping test through pppoe-wan1 and ping times go from ~12ms to ~1200ms, while saturating the upstream so clearly codel is not working there. What am I doing wrong?
