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.

Why is E2E automation important and which role can ZSM play?
Klaus Martiny, Senior Consultant, ORBIT at Deutsche Telekom AG - Chair of the ETSI ISG ZSM

The operations of a Telco Network are more complex than years ago. Virtualization, slicing, 5G, cloudification are impacting the network architecture and the OAM strategy. The current fragmentation of network management solutions makes the problem more challenging. A common, harmonized approach is needed in order to mitigate the complexity and makes the networks manageable. ZSM can help to deliver at least a framework regarding management solutions.

Expert Panel

Title: On the challenges of network programmability and automation under resilience and sustainability stakes

Overview: As we are heading towards nascent 6G networks, this is the appropriate time to do a hindsight exercise to gather the lessons learned to start shaping the networks to come in a coherent and converged manner towards service-oriented, programmable and automatically managed networks.

In this direction, network programmability and automation _with the extreme form known as “zero-touch”_ have drawn the attention of many actors from the IT, Telecom and Cloud sectors. A plethora of initiatives dealing with all related aspects from a global or specialized point of view for 5G and beyond networks can be cited here: TMF ZOOM, ETSI ZSM, ETSI ENI, RAN-related management initiatives (O-RAN, ONF SD-RAN), different EU and non-EU research projects like MON-B5G, 5G-DIVE, 5Growth, 5GZORRO, INSPIRE5Gplus, and last but not least the Hexa-X project recently launched as a flagship 6G European initiative.

With the ever-growing connectivity demand and continually more stringent performance requirements along with operational and environmental costs are pushing the boundaries of network solutions to maximize the efficiency of every deployment and operation action. In parallel to that, the security, resilience, and sustainability stakes are getting a societal and economical importance.

We propose this panel to gather views from research and standards experts focusing on ETSI ZSM ISG, Hexa-X project on 6G, MON-B5G, 5Growth, and 5GDive European projects to discuss how programmability and automation can foster reliability and optimality of networks for applications and services that leverage societies and business.
