Description
Software defined networking (SDN) has made it possible to move the control plane to the software allowing for converged management and control of the network elements (NE) by utilizing standard open interfaces for both the southbound (SBI) and the northbound (NBI) interfaces thereby paving the path for open and disaggregated optical networks. The disaggregation requires interoperability, is highly desired and is in-line with the industry trends where both partial and full disaggregation options exist. In the optical network, it is the optical SDN domain controller that allows for service provisioning, increasing capacity, FCAPS monitoring, operation, and management of the network elements within the open line system (OLS) via standard SBI APIs and protocols. At the same time, these operation and configuration capabilities are also made available to the hierarchical SDN controller via standard NBI APIs and protocols. In this talk, we’ll look at the overall technology, the associated advantages and disadvantages and the way forward.
