Topology Generators



Understanding and automatically generating Internet topology

 

  • Understanding of large-scale Internet structure and underlying physical topology, the manner in which it evolves over time, and the way in which its constituent components contribute to its overall function.
    • BRITE
    • generates models for flat AS, flat Router and hierarchical topologies enhanced by assigning links attributes such as bandwidth and delay.
    • Support for topology imports: GT-ITM (ALT format for both flat and transit-stub topologies), Inet, and NLANR AS (ASconnlist format), CAIDA's Skitter IP level topologies and for router maps from the SCAN Project is also provided.
    • Integration with CAIDA's visualization tool, Otter, allows visualization of generated topologies.
    • Export to simulation software ns, SSFNET, JavaSim and OmNet++
  • Autonomous System (AS) level Internet topology generator
    • Inet - synthetic topologies generation which approximates the actual Internet AS topology
