Mallory,

Thanks for the feedback! We uploaded a new version of the document that 
addresses the nits.

For the minor issue, I’m having trouble coming up with something that will 
address the minor issues you noted below. In particular:


  1.  It’s hard to say what types of messages would be appropriate for a given 
application.
  2.  It doesn’t seem like using different ports really serves as a security 
protection.

If you have suggested text or can elaborate more that will be helpful 😊

Cheers,

Nate

Summary: The document is well written and easy to understand. Where there

exists some ambiguity in the narrative text, I've attempted rewrites in the

nits section below. I've included questions to be considered "minor issues".



Major issues: None.



Minor issue: It seems to me there might be a more general statement needed in

the Intro, last paragraph: [MAY/SHOULD] NOT an application sending

[multi/uni]cast messages also send [multi/uni]cast messages using a different

destination port? (And what does using the Multicast Application Port as the

destination port have to do with it, architecturally speaking?) You could also

preview for the reader why a common port doesn't introduce privacy/security

issues as that seems a curiosity worth an intro mention.



Nits/editorial comments:



The following are rephrasings that, if correct, might improve readability:



 * Intro, second para: The same applies to Source-Specific Multicast (SSM; see

 [RFC4607]) because of uniqueness when both source unicast address and

 destination multicast address are taken together.



 * Firewall considerations section, first para: just remove parentheticals in

 favour of sentence clauses, eg commas.
