Here are my comments.

1. In this definition:

Control Plane Cost:  The overall cost associated with operating the
       Control Plane.  The cost consists of capital costs (for  
hardware),
       bandwidth costs (for the control plane signalling) and any other
       operational cost associated with operating and maintaining the
       control plane.  In the present Internet, the primary current cost
       concern is on the capital hardware."

The final sentence, "In the present Internet, the primary current  
cost concern is on the capital hardware", caught me by surprise until  
I reread it focusing on the context of control plane cost.  Even  
then, I'm not sure everyone would agree that capital hardware is  
their greatest concern when it comes to control plane.  It would  
probably not be hard to create a lively conversation in various  
forums by putting up the strawman that the opex associated with the  
current Internet control plane is insignificant.

I would suggest simply deleting the sentence.

2. Replace "more specific" with "more-specific" throughout except of  
course if it's not being used to mean "more specific route", or where  
it's fully written out as such.  (Also if grepping note that it's  
broken across lines in some cases.)

3. Point 6 of the summary section seems to be redundant with point  
1.  Delete it?

4. Speaking of section 6, can someone remind me why we didn't think  
"provides end-to-end convergence/restoration of service at least  
comparable to that provided by the current architecture" was worth  
including?

5. I made a few trivial proofreading edits to the document and have  
attached a diff.

Thanks,

--John
