Hello all, I am interested in hearing any thoughts you have on a data problem that I have, that I am sure many of you have approached, and which is, of course, a result of the structure of the Internet itself. In my ideal world, I would be able to build a relational database of data traffic between the largest cities worldwide. The data I have found shows gross data traffic between nodes, which includes traffic originated in third-party cities and destined for fourth-party cities, for example, and which does not provide an estimate of the traffic originated in 3 and destined for 4. This means that the data doesn't relate every node in the city system to every other in terms of network traffic inbound and outbound. Have you approached this problem? Do you have any thoughts on how currently available data can be patched for network analysis, or how such a relational database could be built in the future?
