Map of the internet could make it stronger

From the Scientist: “In many ways the internet is like another country. It has its own communities, cultures and even currency. But its infrastructure – the fibre optic cables that span the globe, and the thousands of buildings housing servers and routers – passes through almost every nation…. Previous attempts to map the internet have been from within, using “sniffer” software to report the IP addresses of devices visited along a particular route, which, in theory, can then be translated into geographical locations. But this approach doesn’t work,… Barford and Roughan head up two separate projects that are attempting to change that. Instead of relying on sniffers, they are scouring ISP databases to find published information about local networks, and piecing these together into a global map. Roughan’s Internet Topology Zoo is a growing collection of maps of individual networks. Barford’s Internet Atlas expands on this, adding crucial buildings and links between networks to flesh out the map. So far the Internet Atlas, perhaps the most comprehensive map of the physical internet, maps 10,000 such structures and 13,000 connections.”
