BRITE: A Flexible Generator of Internet Topologies

Abstract BRITE is a parameterized topology generation tool, which can be used to flexibly control various parameters (such as connectivity and growth models) and study various properties of generated network topologies (such power laws, path length and clustering coefficient). BRITE can be used to study the relevance of possible causes for properties recently observed in Internet topologies. Different combinations of possible causes can be tested. In this version, we consider four of them: (1) preferential connectivity of a new node to existing nodes; (2) incremental growth of the network; (3) geographical distribution of nodes; and (4) locality of edge connections. We use BRITE in [BU-CS-TR-2000-0004] to study the origin of power laws and other metrics in Internet topologies.
