hi all

1. i still don't understand the need for the [ ... ] after each term - if
authors could clarify this would be helpful

2. in general, i don't see why this document meant to clarify GMPLS terms
for ASON includes ASON specific terms/definitions and interpretations hence
the need for each "ASON terms" sub-section is unclear

some other specifics

3. " Node [Control & Data Planes] is a logical combination of a
     transport node and the controller that manages the transport node.
     In early deployments, all control plane and data plane functions
     associated with a transport node were collocated in a node and
     referred to as a Label Switching Router (LSR)."

the second sentence is imho outside the scope of such definition

4. "3.4.1. GMPLS Terms

   Label [Control Plane] is an abstraction that provides an identifier
   for use in the control plane in order to identify a transport plane
   resource."

how to interpreet an MPLS label with this definition ? or is MPLS out of
scope ?

5. "3.5.1. GMPLS Terms

   Unidirectional data link end [Data Plane] is a set of resources of a
   particular layer that belong to the same transport node and could
   be allocated for the transfer of traffic in this layer to the same
   neighbor in the same direction."

what "same transport node" means here ?

6. " The need for advertisement of adaptation and termination capabilities
   within GMPLS has been recognized and work is in progress to determine
   how these will be advertised. It is likely that they will be
   advertised as a single combined attribute, or as separate attributes
   of the TE link local end associated with the link interface."

afaik, GMPLS is able to advertize "termination" capabilities -

thanks,
