Summary: Ready for publication as an Informational RFC but with nits 


that should be considered before publication




Nits/editorial comments:



There are 6 authors listed - please double-check the guidance in section 


4.1.1 of RFC7322.


If retaining all the authors still makes sense, please help Adrian by 


providing an argument



that he can pass to the RFC Editor.



The shepherd writeup indicates a solution ID is ready. I didn't check to 


see how the requirements


listed here were reflected there. Would it make sense to provide a 


reference? (While I see no harm


in publishing the document, it's not clear how doing so will be helpful 


if the requirements were


uncontentious as the writeup implies. There are few enough of them that 


adding a short list in



the mechanism document might be more effective.)



Items 2 and 3 in section 3.4 are confusing as currently written. 2 seems 


to be talking


about the case that the current path is still optimal. Is 3 trying to 


talk about the case


where there is no path, not even the current path, that will work? If so 


the "(i.e., other



than the current path)" in 3 doesn't make sense.

Should you have captured a requirement that any mechanism implementing these


requirements be extensible to allow for cases like polarization based 


multiplexing



when they eventually come along?



Please consider reordering the sentences in section 3.5 - the last 


sentence seems



to be talking about the first paragraph?



You say "mechanisms defined in this document" several times in section 


4, but this



document defines no mechanisms.
