Dynamic Reconfiguration of WDM Virtual Network Topology over SDM Networks for Spatial Channel Failure Recovery with gRPC Telemetry
2022 Optical Fiber Communications Conference and Exhibition (OFC2022)
We experimentally demonstrate the dynamic reconfiguration of WDM VNTs in response to SDM spatial channel failures. We present an SDN control architecture with gRPC-telemetry and analytics to detect failures and restore failed virtual WDM links.

Scalability analysis of machine learning QoT estimators for a cloud-native SDN controller on a WDM over SDM network
2022 - Journal of Optical Communications and Network, Vol. 14, Issue 4, pp. 257-266
Maintaining a good quality of transmission (QoT) in optical transport networks is key to maintaining the service level agreement between the user and the service provider.

SDN Control Architectures for WDM over SDM (WDMoSDM) Networks
2021 Photonics in Switching and Computing Conference
We provide an overview of SDN control architectures for WDM over SDM (WDMoSDM) optical networks. We address dynamic management of end-to-end connec- tivity services and WDM virtual network topologies (VNTs) for partially disaggregated multi-domain WDMoSDM networks.

First Scalable Machine Learning Based Architecture for Cloud-native Transport SDN Controller
2021 Optical Fiber Communications Conference and Exhibition (OFC2021)
We present a cloud-native architecture with a machine learning QoT predictor that enables cognitive functions in transport SDN controllers. We evaluate the QoT predictor training and auto-scaling capabilities in a real WDM/SDM testbed.
