Re: [ippm] Fwd: Expiration impending: draft-ietf-ippm-reporting-metrics

[Daniel Genin <[e-mail]>]

A very lucid and well written exposition on the relevance of metric's 
consumer to the way that it should be defined. It is surprising this 
important point has not been addressed earlier.

Just a couple of comments:

I. In Section 5.1.2 the bulleted list item 2 appears to suggest that 
orthogonality of metrics is a desirable property, however, no 
explanation for this is given. Moreover, metrics appearing in Section 6 
do not appear to be orthogonal suggesting that orthogonality is not a 
necessary property. If orthogonality is a desirable property in the case 
of delay and loss metrics but not in the case of raw capacity metrics 
this probably needs to be clarified.

II. Minor grammatical corrections:
     1. Section 5.2, Paragraph 1, line 5 "...is based a conditional 
distribution..." should probably be "...is based on a conditional        
distribution...".
     2. Section 6.2, the first letter of the title needs to be capitalized.
     3. Section 6.6, Paragraph 1, line 2 "...gives a the user..." should 
probably be "...gives the user..."
     4. Section 6.6, Paragraph 2, line 1 "What ways can Utilization  be 
measured..." should probably be "In what ways can Utilization be 
measured..." or "How can Utilization be measured..."
     5. Section 7.5, Paragraph 1, line 2 "...gives a the user..." should 
probably be "...gives the user..."

Hope this is useful.
Best regards,
Daniel
