[secdir] SecDir review of draft-ietf-pwe3-fat-pw-06

[Yaron Sheffer <[e-mail]>]

I have reviewed this document as part of the security directorate's 
ongoing effort to review all IETF documents being processed by the IESG. 
These comments were written primarily for the benefit of the security 
area directors.  Document editors and WG chairs should treat these
comments just like any other last call comments.


This document proposes the addition of MPLS flow labels, to enable 
multiplexing of a single pseudowire (PW) over multiple paths, while 
retaining the packet order within each IP flow.


The document's security considerations simply reference several former 
MPLS documents. I believe this is appropriate in this case.


Nits: although very readable, the document needs another round of 
proofreading. The following is from the abstract and the first sentence 
of the Introduction (!):


- Abstract: "most forwarding engines": the sentence is unclear - hash 
what? Also a dangling "END" at the end of the abstract.


- Intro first sentence: exit -> exist, equipments -> equipment/devices.


Thanks,

     Yaron
