cyber and real networks --- This video is quite illustrative. It seems that the establishment of submarine cables during the last 30 years have been following the pattern of the global economy network. One can see that the cables are strongly concentrated in some areas, not only because of technical or economic reasons but also political and strategic. Would be more suitable to talk about a centralized graph than a network in topological sense? The physical layer design follows the transport and content layers, or the other way around?
