An Insider’s View of the JT-NM Tested 2022 Network

This presentation will describe the network design, provisioning of network services, and automation of network configuration that lead to the 2022 JT-NM Tested event in August being hosted on the most realistic ST 2110 live production network to date. In order to maximise the industry benefits of the JT-NM Tested event, it was decided to design the network and associated network services in a way that reflects the best practices that we see employed in today's live production networks. Hear how the media and management networks were architected with universal access to the basic network services that are needed for NMOS operation (DHCP, DNS), and how these design principles provide scalability and reduce failure domain size ("blast radius"). As the scope of the event has continued to grow, it was also obvious that taking an automated approach to the design and creation of switch configs would reduce human error, event setup time, and make design changes easier to implement. Hear how this was achieved with an open-source Ansible based approach.
