Dear Dave, dear all

please, let me introduce Andrew to this list, who is the driving force behind CAKE-autorate's design and implementation (which started from a more theoretical discussion in the OpenWrt forum before turning into something tangible). There are other alternative approaches for the rate-tracking problem many discussed in this longish forum thread: https://forum.openwrt.org/t/cake-w-adaptive-bandwidth/108848 (which is great as this occasionally leads to quite interesting discussion about how the different teams tackle common issues) but Andrew's autorate appears to the fastest moving with low software requirements (every router should run bash anyway ;) ).

Kind Regards
