> How is a "marginal link" defined/detected? The current implementation uses ETX (MobiCom 2003), which is not very good but relatively easy to implement portably. See Appendix A2 of RFC 6126 for the gritty details. (In true truth the it uses something called Z3, which combines ETX with interference avoidance, and which I haven't published yet.) We're planning to do something smarter in the future by hooking into Linux's rate estimator (the idea is due to Dave), but we've got plenty of more urgent work. (Such as merging the source-specific code and writing a paper about Z3.) At any rate, the current ETX code will remain for non-Linux platforms. -- Juliusz _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
