Last Call Review of draft-ietf-pwe3-fat-pw-
review-ietf-pwe3-fat-pw-secdir-lc-sheffer-2011-05-19-00

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,
