Over the last decade, the Internet in Korea has developed rapidly. The number of ASes in Korea is 755. However, there has been no significant effort to obtain an accurate picture of the Internet AS-level topology. To construct more complete set of Korea AS-level topology data all the available data sources are critically reviewed and compared. Three data sources, which can be used to infer Korea Internet AS-level topology, are selected; BGP data of UCLA "Internet Topology Collection", IRR data and IXP data. It is known that global Internet AS-level topology follows power-law distribution. In this paper, we also investigate if the Korea Internet AS-level topology follows power-law distribution.
