    abstract =  {Generalized Multi-Protocol Label Switching (GMPLS) control allows each network element (NE) to perform local resource discovery, routing and signaling in a distributed manner. On the other hand, with the development of software-defined transport networking technology, a set of NEs can be controlled via centralized controller hierarchies to address the issues from multi- domain, multi-vendor, and multi-technology. An example of such centralized architecture is Abstraction and Control of Traffic Engineered Networks (ACTN) controller hierarchy described in RFC 8453. Instead of competing with each other, both the distributed and the centralized control plane have their own advantages, and should be complementary in the system. This document describes how the GMPLS distributed control plane can interwork with a centralized controller system in a transport network.},
