Internet topology
This is the network of connections between autonomous systems of the Internet.
The nodes are autonomous systems (AS), i.e. collections of connected IP routing
prefixes controlled by independent network operators. Edges are connections
between autonomous systems. Multiple edges may connect two nodes, each
representing an individual connection in time. Edges are annotated with the
timepoint of the connection.
