This workshop presentation delves into the future of network standardization, specifically focusing on naming and addressing issues that arise in contemporary and emerging network systems. It covers various aspects such as the challenges of network integration, technical limitations, and the necessity for a clean design slate. An emphasis is placed on geographical addressing, the importance of separation between identifiers and locations, and the need for improved system requirements. The scenarios proposed include packet transferring using a geographical addressing scheme, highlighting innovative approaches for effective network design.
