COMMENT:
----------------------------------------------------------------------

I support Ben Kaduk’s DISCUSS position.

** Section 1.  Per “There are some applications of the alternate marking method
where there are a lot of monitored flows and nodes.” -- Editorial. 
“alternative marking methods” is lower case but “Alternative Marking
methodology” is upper case in other places

-- “a lot of monitored” seems colloquial and imprecise and begged for me,
“what’s a lot”? (subsequent text says “n and m are high values”, but I also
don’t have a sense for what that might be)

** Section 1.  Per “Without network clustering, it is possible to apply
alternate marking only for all the network or per single flow.  Instead, with
network    clustering, it is possible to use the network clusters partition …”,
the phrase “network clusters partition” doesn’t parse for me.

** Section 4.  Per “By Using the "traditional" alternate marking method only
point-to-point paths can be monitored.”, perhaps say alternative marking per
RFC8321 instead of “traditional …”.

** Section 4.1.  “In general there are different options: the monitoring
network can be obtained by considering all the possible paths for the traffic
or also by checking the traffic sometimes and update the graph consequently.”

-- Editorial: s/In general there are different options: … by checking the
traffic sometimes and update the graph consequently/In general, there are
different options: by periodically checking the traffic and updating the graph
as appropriate/

-- Is there any guidance on the how to frequently this evaluation of traffic
should be?

** Section 5.  How generalizable is the flow description?  These statements
seem inconsistent:

-- Section 4 says “Multipoint Alternate Marking enables the performance
measurement for multipoint flows selected by identification fields without any
constraints (even the entire network production traffic).

-- Section 5 says “The flow definition is generalized here, indeed, as
described before, a multipoint packet flow is considered and the identification
fields of the 5-tuple can be selected without any constraints.

** Section 9.  I didn’t understand what this section was saying that is
different than Section 10.  IMO, the “SDN Controller calibrating for
performance measurements” and [I-D.song-opsawg-ifit-framework] descriptions
seemed like “Examples of applications” covered in Section 10.   The title of
this section “An Intelligent Performance Management approach” seemed a little
“marketing like”.
