Newbie Cake user here. Happy to report I've recently managed to compile and run Cake on my home router, a Raspberry Pi 3B+ (Kernel Version: 4.14.62-v7+). Did not know of bufferbloat until quite recently, and I learned a bunch. Today is day 2 on Cake, and quite pleased with its outcome - thank you for curbing the menace! I've jotted down the steps I took to get it setup. Until 4.19 becomes common I hope it helps those who are looking to get Cake running on their Pi's. https://evuraan.info/evuraan/stuff/bufferbloat.html#compile Here's my Pi with Cake: $ tc -s qdisc show dev eth1 qdisc cake 8001: root refcnt 2 bandwidth 5Mbit diffserv3 triple-isolate nonat nowash no-ack-filter split-gso rtt 100.0ms raw overhead 0 Sent 3055787687 bytes 6902761 pkt (dropped 49776, overlimits 9775200 requeues 0) backlog 0b 0p requeues 0 memory used: 360982b of 4Mb capacity estimate: 5Mbit min/max network layer size: 42 / 1514 min/max overhead-adjusted size: 42 / 1514 average network hdr offset: 14 Bulk Best Effort Voice thresh 312496bit 5Mbit 1250Kbit target 58.1ms 5.0ms 14.5ms interval 153.1ms 100.0ms 109.5ms pk_delay 1.9ms 1.3ms 1.7ms av_delay 230us 189us 414us sp_delay 6us 4us 11us backlog 0b 0b 0b pkts 19446 6229022 704069 bytes 1050305 2850269228 279273436 way_inds 18 313898 991 way_miss 2953 203634 677 way_cols 0 0 0 drops 0 49764 12 marks 0 10 0 ack_drop 0 0 0 sp_flows 1 2 1 bk_flows 0 1 0 un_flows 0 0 0 max_len 98 1514 1514 quantum 300 300 300 $ modinfo sch_cake filename: /lib/modules/4.14.62-v7+/kernel/net/sched/sch_cake.ko description: The CAKE shaper. license: Dual BSD/GPL author: Jonathan Morton srcversion: 1FE38B4A137EF6ADC576887 depends: nf_conntrack name: sch_cake vermagic: 4.14.62-v7+ SMP mod_unload modversions ARMv7 p2v8 Best!
