Hi, A few questions for the CAKE experts here:
I’m trying to untangle the information available in the openwrt wiki: https://openwrt.org/docs/guide-user/network/traffic-shaping/sqm https://openwrt.org/docs/guide-user/network/traffic-shaping/sqm-details and for the latter especially the part here: https://openwrt.org/docs/guide-user/network/traffic-shaping/sqm-details#sqmlink_layer_adaptation_tab For ADSL/VDSL, I believe the instructions are clear and the Luci interface is too. However for ethernet/fiber, I’m confused: In the first list of this paragraph it is first suggested to use « Ethernet with overhead » and set the per-packet overhead to 44 for FFTH (which seems like a large value for this use case), then later in the second list (« the details »), it is suggested to use « None », directly contradicting the above. The 44 byte overhead for ethernet/FTTH is also mentioned here: https://openwrt.org/docs/guide-user/network/traffic-shaping/sqm More specifically, there are two (increasingly common I think) use cases I would like to document with your help: - FTTH with plain DHCP, no VLAN - FTTH with PPPoE, no VLAN (And adding a footnote for the extra overhead to consider if the above include a VLAN tag) In the latter case (FTTH with PPPoE), another point that needs to be clarified is: do we apply CAKE to the ethernet interface, or to the PPP interface? (and I assume that depending on the answer, the overhead settings will have to be adjusted). Also in that case, what about ISPs that allow sending a full 1500 frame over PPPoE (using 1508 MTU on the underlying ethernet interface)? Thanks for your input, T _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
