The BoF session about CNaaS at TNC'25 had the following goals:

• To provide a forum for exchanging ideas, knowledge and experience of
  developing, deploying, standardizing and testing elements of a Campus of a
  Network Service (CNaaS) portfolio.
• Cooperate in the development of tools, software and standards
  of a CNaaS portfolio by exchanging best practices, business models, service delivery
  processes and technical solutions.
• Strive as a group to provide collective, coherent policies for CNaaS services
  to achieve larger economies of scale and more robust service delivery over time.
  Develop standardized frameworks and interoperable solutions for
  CNaaS, and promote the adoption of it. This ensures that services are consistent, reliable,
  and compatible across different NREN organizations.
• Provide an open collaboration platform, sharing information, standards and
  tools in order for other NRENs and organizations to use (and to provide input).
