Abstract

Multi-vendor interoperability can be achieved at node and network levels by relying on standard data modeling. YANG represents an attractive data modeling solution for network component definition. This article reports on the work done on YANG models for optical networks with particular reference to flexible-grid networks. In addition to a YANG model description for link, node, and media channels, YANG for a sliceable transponder is introduced given the importance of such a data plane device for the next generation backbone. Then a contribution is provided in proposing YANG models for events and state machine to further extend and increase the programmability of networks. This latter contribution is particularly relevant in the case of faults or physical layer degradation in a network. Finally, YANG models are validated in an experimental control plane testbed.
