Due to the high manufacturing, launching, and updating cost of LEO mega- constellations, it is expected that ISTNs can be well designed and evaluated before the launch of satellites. However, the progress of designing, assessing, and understanding new network functionalities and protocols for futuristic ISTNs faces a substantial obstacle: lack of standardized evaluation methodology with acceptable realism (e.g. can involve the unique dynamic behaviors of ISTNs), flexibility, and cost. This memo first reviews the unique characteristics of LEO mega-constellations. Further, it analyzes the limitation of existing evaluation and analysis methodologies under ISTN environments. Finally, it outlines the key requirements of future evaluation methodology tailored for ISTNs.}, }
