Abstract 
 
   Generalized Multi-Protocol Label Switching (GMPLS) control allows 
   each network element (NE) to perform resource discovery, routing and 
   signaling in a distributed manner. On the other hand, with the 
   development of software-defined transport networking technology, 
   central controllers are introduced to transport networks to control 
   a set of NEs.  

   In transport networks, the GMPLS control has many mature mechanisms 
   such as RSVP-TE, OSPF-TE, and LMP, so that GMPLS can be applied for 
   the NE-level control in the centralized controller systems.  

   This document describes how GMPLS control interworks with 
   centralized controller systems (e.g. ACTN) in transport network.
