Abstract: The research of the macro-topology between large-scale software and AS-level Internet has important significances in the further comprehension and application for their structures. According to the complex network characteristic which is reflected by the macro-topology between largcscale software and A}level Internet, their structures were converted to network topology, analyzed and compared from connectivity, degree distribution characteristic, small-world characteristic and hierarchy, using the methods of complex network metric and analysis, then some macro-topology similarities and differences between large-scale software and AS-level Internet were discovered. Additionally, the reasons of them were discussed.

Key words: Complex networks,Connectivity,Free-scale,Small-world,Coreness
