Information about how Autonomous Systems are interconnected is stored at BGP (Border Gateway Protocol) routing tables, are all in text format. There are several public "looking glass" servers that publish the routing tables for the Internet core formed by those tier-1 core routers free of charge every day. However, the BGP routing tables contain just lists of ASs that represent the way the Internet cores are interconnected, but only in the text format. An integrated system which downloads the BGP routing tables from multiple looking glass servers, stores the BGP routing tables in a database that allows efficient storing of them, and visualizes the Internet connectivity by graphics based on the BGP routing tables. The system will come with some fringe functions, such as double-clicking an AS-to-AS link in the output visualization would contact Internet naming-service servers, such as WHOIS servers, to resolve the AS Number into actual carrier's name (such as AT&T, Sprint, Verizon, UUNET, and Colorado-Super Net, etc).
