Dear TEASers,

We've just updated the new revision of draft-ietf-teas-gmpls-controller-inter-work. The main changes include:

  -  Added the description of FRR in GMPLS-centralized controller interworking scenario in Section 7.4.5 (as Lou mentioned in the last IETF meeting);
  -  Distinguished single-domain and multi-domain restoration in GMPLS-centralized controller interworking scenario in Section 7.4.3 and 7.4.4
     (Section 7.4.4 is newly added to describe the multi-domain restoration);
  -  Editorial changes, e.g., added a reference to G.808.1 for APS.

Comments are always appreciated. Thank you.

   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 issue from multi-
   domain, multi-vendor and multi-technology. An example of such
   centralized architecture is 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.
