A structural model of Internet organization discovery

This paper presents a highly structured model to automatically discover Internet organizations from the data of RIR (Regional Internet Registry) and IRR (Internet Routing Registry), where network operators register their networking resources such as IP addresses and routing policies. Our basic idea is to discover network operators that have close ties among each other from those registry activities, and consider them as being from the same organization. With the data from two RIRs, this model produces to date the first organization level network of current Internet. The model shows its reasonability in our validation with real Internet routing data, and is likely to be applied extensively in networking area.
