The mechanism for scalable Registry System with aggregatable address allocation on WIDE 6bone

The change over from IPv4 to IPv6 entails a potential increase in the numbe r of records that the Registry System must maintain. Currently, only a few Network Information Centers (NICs), controlled by Internet Assigned Number Authority (IANA), operate their Registry Systems. As they concentrates data into several Registry System, it is not scalable. This paper focuses on th e scalability issue in a Registry System and Mie Advanced Registry System ( MARS) is proposed. Through the collaboration of independent Registry System s, MARS ensures data consistency as well as making it possible to access da ta managed hy other Registry Systems. A prototype system of MARS is impleme nted, maintained and managed on the WIDE 6bone. Some lessen from the operat ion of MARS give also described.
