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 defines additional GMPLS-specific requirements on the PCE 


architecture.






It would be an understatement to characterize this reviewer as a 


non-expert on PCE and GMPLS. That being said, I believe the Security 


Considerations are correct in saying that this document does not add any 


additional security issues on top of PCE.






I would recommend to add a pointer to where such considerations are in 


fact listed, e.g. Sec. 10 of RFC 5440. Though security folks will cringe 


at TCP-MD5 being described as the most practical security solution in 


that section.




Thanks,
