[Bloat] Cake on Raspberry Pi 3B+ (Kernel Version: 4.14.62-v7+)

2019-01-16 Thread Evuraan 
Greetings!

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.

Here's my Pi with Cake:

And they make much of its no-brainer Diffserv configuration, which is nice 
considering they appear to target environments where Diffserv is actually used.

[Bloat] Cake in Riverbed?

2019-01-16 Thread Rich Brown 
I can't remember whether I had seen this on the list or not: It appears that 
Riverbed is offering CAKE on its branch gateways...
