Abstract
The Network Infrastructure as Code paradigm empowers network engineers to create a repository
of configuration templates and automation scripts, facilitating the automated configuration,
management, and monitoring of the network infrastructure and services. Moreover, applying
standardised approaches to high-level network processes, utilising a common data model for
network description, and employing standardised open APIs for components, can offer reusability
of the implementation of automated and orchestrated network solutions. In its recent activities, the
GÉANT Global Platform for Labs (GP4L) group is actively collaborating with the Polish national
research and education network (NREN) PIONIER focusing on developing a generalised, reusable
approach to orchestrating service provisioning. By abstracting the process to define common steps
in service provisioning, the goal is to provide a collaborative blueprint that other NRENs can
adopt. The modular nature of the approach allows the creation of a repository of processes, subprocesses, and elementary tasks that can be reused across the community. This article presents the
concept of developing generalised reusable processes and discuss challenges and decisions while
working on the PIONIER use case. Aiming for reusability and sharing lessons learned, it builds
towards a community of network automation and orchestration activities.
