[PANRG] On the new text on ECN: draft-irtf-panrg-what-not-to-do-16

[Gorry Fairhurst <[e-mail]>]

HI,

Two observations on ECN in what may have been learned?

* I think the "one chance" is per one /Generation/ of equipment for 
hardware, possibly less time for software updates - but hard to 
eliminate deployed critical bugs completely.

* "Measure widely before, but important also gently test during initial 
deployment", to avoid the pain when there are issues and therefore to 
provide a chance to refine the design if there is a problem, and reduce 
the pain of trying.

I like the additional thought from Eric (in the RG meeting) on 
mitigating user pain by using fallback techniques, so they do not share 
your pain when something happens to go wong.

Is this a typo?: /Cannot be recovered at TCP layer/
- it seems like a partial sentence, does need a /This.../
