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

** Section 2.
   Many legacy OAM tools can be used in DetNet networks, but they are
   not able to cover all the aspects of deterministic networking.

What is a legacy tool?

** Section 2.

   For example, appropriate placing of MEPs along the path of a DetNet
   flow is not always a trivial task and may require proper design,
   together with the design of the service component of a given DetNet
   flow.

Agreed.  However, it seems me to that there is a missing sentence explicitly
linking OAM to placing these MEPs.

** Section 8.  This section seems to be missing mentioned that OAM mechanism
could be tampered with depending on their construction and that some OAM tools
are dual-use potentially enabling reconnaissance by an attacker.  These and
other topics are covered in the Security Considerations of RFC7276.

** Section 9.  The GENART reviewer (Mallory Knodel) also notes that OAM
mechanism can be used as the further basis of reconnaissance by fingerprinting
their features.
