Redes ópticas definidas por software: um estudo do controle de equipamentos NETCONF/YANG usando os modelos OpenROADM

Abstract

The constant evolution and increasing over the network elements to keep the traffic demand has made service providers to search for other alternative solutions in a way to automate network operations and reduce the monitoring cost. Therefore, the optical transport network integrated with software defined network concepts has become an alternative solution because it allows the unification of the network topology, adapts the configuration on different equipment vendors, and separate the control and data plans. To do so, the network elements must be disaggregated e its functionalities be abstracted by standard or common data models. OpenROADM has become a feasible solution to disaggregate network elements in the optical transport network because it provides a deep and realist optical domain level for functions, layers, interfaces, alarms and metrics, which it is needed to optimize the resource utilization. The objective of this paper is to study how the OpenROADM models will disaggregate the network equipment and its functions.
