摘要: 针对在P2P环境中可扩展标记语言的端点目录管理的要求,提出一种APNI索引方法,该索引方法利用素数索引方法(Prime Number Index)并加以改进,借以素数索引表和层次索引表辅助。实验结果表明,APNI查询结果比Prime Number Index更快。

Abstract: In order to meet catalog administration of Extensible Markup Language(XML) in P2P, this paper proposes an index method Advanced Prime Number Index(APNI), which uses the prime number index method and improves it with accessorial structures of Prime Number Index table and hierarchy index table. The purpose is that it queries XML more flexibly. Results of the experience show that it queries XML using APNI more quickly than using Prime Number Index.

Key words: eXtensible Markup Language(XML), P2P, Advanced Prime Number Index(APNI), Prime Number Index
