So what I want to see is a proposal for a routing protocol that specify link metrics for a set of commonly used link types in homes. This spec could be BCP. Does it need to be a routing protocol? Just to throw another possible protocol into the mix being tossed around (like we don't have

If you have hardware with a built-in switch that can report the link-speed, The WNDR3700v2 under OpenWRT appears to do so: # swconfig dev switch0 show | grep 'link:' link: port:0 link:down link: port:1 link:down link: port:2 link:up speed:100baseT full-duplex link: port:3

Does it need to be a routing protocol? Just to throw another possible protocol into the mix being tossed around (like we don't have enough), I don't think current protocols used by ISPs or enterprises fits our plugplay requirements. Also, there is a lot more wireless in homes. That doesn't

A marginal link is simply one that has a measurable amount of packet loss. Ok, re-reading this exchange, it looks like I may have wrongly assumed that people are aware of background. I'll need to put that into the routing comparison document, this is as good a place as any to draft my text.
