“…2) IETF Standardization of SDN/GMPLS Interfaces: GMPLS is the most popular control plane for optical transport networks. Several demonstrations of dynamic optical transport networks used open source interfaces for centralized SDN/OpenFlow+ and proprietary interfaces and protocols for distributed GMPLS [198]. Multiple architectures and protocols have been proposed, each with different degree of integration and flexibility between the two control planes.…”

Paradoxically, with an ever-increasing traffic demand, today transport-network operators experience a progressive erosion of their margins. The alarms of change are set, and Software Define Networking (SDN) is coming to the rescue with the promise of reducing Capital expenditures (CapEx) and Operational expenses (OpEx). Driven by economic needs and network innovation facilities, today transport SDN (T-SDN) is a reality. It gained big momentum in the last years, however in the networking industry, the transport network will be perhaps the last segment to embrace SDN, mainly due to the heterogeneous nature and complexity of the optical equipment composing it. This survey guides the reader through a fascinating technological adventure that provides an organic analysis of the T-SDN development and evolution considering contributions from: academic research, standardization bodies, industrial development, open source projects and alliances among them. After creating a comprehensive picture of T-SDN, we provide an analysis of many open issues that are expected to need significant future work, and give our vision in this path towards a fully programmable and dynamic transport network.

Interworking of GMPLS and OpenFlow domains: Overarching control of flexi grid optical networks

Abstract: Both GMPLS and OpenFlow are positioned to become the pillars of a dynamic control plane for optical transport networks, each with its own strengths and weaknesses. This paper summarizes both approaches and discusses potential SDN interworking architectures.
