Abstract:

Based on analysis of internet topology model and metrics, five topology generators are compared on both autonomous system （AS） level and router level. The accuracy of these generators is checked by counting several topology metrics of the generated graphs and with indicators. Evaluation of their performance is given on the basis of comparison. It is shown that new Internet topology has the best performance on AS level, and TopGen generates most accurate topology on router level.

Key words: Internet topology model, topology generator, autonomous system level, router level, comparison in performance
