Extending and enhancing GT-ITM

Abstract

GT-ITM is a collection of software tools for creation, manipulation, and analysis of graph models of internet topology. It has been used by networking researchers in a variety of ways, most often to create topologies for use in simulation studies. This paper describes the features of a new release of GT-ITM, including enhanced visualization capabilities; a routing and forwarding module for use with large graphs; and support for modeling of interdomain routing policies.
