[Cake] why "triple-isolate"? Why not just "isolate?"

[Sebastian Moeller]

Hi Dave,

Cake offers three relevant per-IP "isolation" options, dual-srchost, dual-dsthost, and triple-isolate. The dual options are relatively straightforward, they promise to separate by either SRC or DST up address of the packets, allowing easy prediction what they should do to a given set of flows between internal and external machines. They for example allow to set up either fairness by external IP addresses or what commonly seems to be wanted fairness by internal IP addresses. BUT to work correctly one needs to configure the correct directionality for ingress and egress. Triple-isolate promises to do something in-between per-internal-IP and per-internal-IP fairness making it possible to forego having to configure the right "direction" into the shaper. The goal making it easier for the user to get a reasonable, albeit not perfect, fairness guarantee is surely laudable; what I so far have not seen is a top level description what it does exactly and data showing that it DTRT.

Best Regards
        Sebastian
