AS-PATH Verification Method for AS Routing Integrity in NDN

摘要

The present invention relates to an AS path integrity verification method of a DN-based network. The NDN-BGP router according to the present invention extracts an AS number and an AS network name when receiving an interest packet for AS path verification for AS path integrity verification. In addition, by comparing the AS number set in the NDN-BGP router with the extracted AS number, if the AS numbers are different, it is checked whether a related entry exists in the PIT table. Also, as a result of the check, if there is no related entry in the PIT table, the next-hop AS of the neighboring NDN-BGP router is searched using the AS network name as a search term. In addition, if the Next-Hop AS does not exist, it responds by generating an Error Data packet, whereas if the Next-Hop AS exists, the router name and VERIFICATION An Interest packet for verification request with a name is generated and the Interest packet is transmitted to the NDN-BGP router designated by the Next-Hop.
