Overview

We have built a tool that allows the for Multiple perspectives of Autonomous Server Mapping (M-PASM). The tool can access and retrieve evegrow's DIMES and CAIDA's Skitter daily released AS edges. The tools facilitates data validation of AS numbers through comparison with databases at the five regional Internet registries (RIRs). M-PASM can allow for mapping AS number to their apparent geographical locations and hence allows for constructing a picture of global AS connectivity. It implements topology analysis features that allows for temporal comparisons of the evolution of the AS topology.

Features

Automatic parsing of DIMES and CAIDA data for any given date
Mapping AS numbers to their corresponding countries
Tracking changed in AS number over time
K-shell Analysis
Visualization:

A number of network layouts
Changes in K-shell distribution
