Call for Papers
In the rapidly evolving landscape of computing, sophisticated network infrastructure forms the backbone of modern enterprise business, data center functionalities, and extensive Internet services. Next-Generation Network Observability (NGNO) is defined as an advanced, intelligent framework for comprehensively understanding, analyzing, and optimizing the behavior of modern network infrastructures in real time. It transcends traditional network measurement by integrating multi-dimensional telemetry, AI-driven analytics, and cross-domain correlation to address the complexity of dynamic, distributed systems such as cloud-native applications, microservices, edge/IoT networks, and AI-driven workloads. The deep insights into the operational states and resource dynamics of network infrastructure prove essential not only for troubleshooting performance bottlenecks and maintaining service quality but also for optimizing resource allocation and strengthening security.
This workshop will bring together experts and practitioners from the fields of network monitoring, management, operation, and maintenance to discuss and present best practices, innovative tools, early ideas, and emerging techniques in network observability. It will cover a variety of topics, including capturing observability signals, correlating monitoring data, and detecting failures in network infrastructure and applications. The aim of this workshop is to provide a collaborative platform for identifying challenges and opportunities in establishing, applying, and leveraging observability for network infrastructure.
