1st Joint International Workshop on Network Programmability & Automation (NetPA 2021)
Monday 25 October 2021

With the same spirit of CNSM as a whole, the workshop on “Network Programmability and Automation” (NetPA) aims at providing an international forum for researchers and practitioners from academia and industry at large, including network operators, service providers, equipment manufacturers and IT companies, to discuss and address the challenges deriving from network programmability and network zero-touch automation for the delivery and operation of networks and services. On the one hand, the workshop will discuss the use of analytics and AI-based models to perform decision making at abstracted levels of the network to bring flexible and adaptive network service provisioning while ensuring smooth service continuity, SLA-compliance and service assurance. On the other hand, the workshop captures the evolutions of networking protocols towards more performance and security. This includes the design of high-level languages and associated tool chains for specifying network and nodes behaviors, automated methods and tools for validating both control and data plane operation; protocols for network programmability like Segment Routing; programmable data plane architectures, hardware platforms, software execution environments; network applications addressing open problems in traffic engineering, measurement, and problem diagnosis.
