To be upfront, my current conclusion is that we don't have all the information. Without the devices, no conclusions can be ascertained. That being said, teach me more. What is exactly is a file's life cycle and its relevance in this case? Do I understand you correctly that routers maintain files of connections? I knew that servers maintained files of connections but not routers. Perhaps I was wrong.  If I understand you correctly, to be comprehensive, a need for the server(s) and any and all routers is needed. Am I on the right track? Also to your point, one would need the original source and all its dessiminations. Again, am I on the right track?
