Question on TLV Length Calculation

["Ong, Lyndon" <Lyong@Ciena.com>]

Hi Folks,

 

Simple question on length calculation for RSVP-TE TLVs:  I've noticed that

draft-ietf-ccamp-ethernet-traffic-parameters-03.txt has adopted a method of

calculating TLV length from RFC 4420, where the length includes only the

value portion of the TLV, and does not include the header (type and length

bytes) or any padding bytes.

 

This is a bit different from how length is computed for objects and sub-objects,

where length includes header as well.  Having not followed the discussion

on RFC 4420 closely, can someone clarify:

 

-- is this method of length calculation to be followed on all new TLVs defined

for RSVP-TE?

 

-- if not, is there some basis for deciding what calculation to follow when

defining a new TLV?

 

Thanks,

 

Lyndon
