Re: [mpls] Poll on draft-koike-mpls-tp-temporal-hitless-psm

[[e-mail]]

Hi 

One comment:

I do not think the descriptions in section 5 are accurate:
"Packet loss and packet delay measurements are OAM functions in which 
hitless and temporal segment monitoring are strongly required because 
these functions are supported only between end points of a transport 
path."

For according to the descriptive scopes at the section 2.9.5 of RFC6374, 
the packet loss and delay measurement functions are not strictly limited 
only between endpoints: 
"In the case of an LSP, it may be desirable to measure the loss or delay 
to or from an intermediate node as well as between LSP endpoints.  This 
can be done in principle by setting the Time to Live (TTL) field in the 
outer LSE appropriately when targeting a measurement message to an 
intermediate node".

Since this is a requirement document and if the inaccuracy does not affect 
this document, please count "yes/support" from me to support this 
adoption.

Regards

Fei
