Accurate real-time availability of transmission parameters at the network controller has the potential to significantly improve the efficiency of control and management operations, particularly in the case of soft failures where detection and localization procedures are typically affected by the long monitoring time intervals usually adopted in current Elastic Optical Networks (EONs). In this paper, we report on the design, implementation and experimental demonstration of a telemetry service exploiting the gRPC protocol to enable on-demand streaming of real-time monitoring parameters, dynamically retrieved from a configurable set of network devices. The telemetry service is efficiently introduced for Software Defined Networking in EONs, also accounting for disaggregated network elements through standard YANG-defined network models. The implemented telemetry service is experimentally validated for partial and fully disaggregated architectures over networking scenarios where soft failures not addressable through traditional monitoring solutions are successfully detected and localized. Moreover, detailed performance evaluation is conducted varying the number of subscribed network elements, the type of communication (e.g., compressed vs. uncompressed, bundled vs. unbundled), showing remarkable scalability performance particularly in the case of compressed and bundled telemetry configurations.
