| 摘 要： | JXTA 2．0参考实现中，索引发布和查询机制是基于索引固定分布的策略。现有索引查询方案中集合点的RPV(flemiezvous Peer View)松散一致性会导致查询请求在集合点之间重复巡查(walker)的问题。提出使用索引的动态分布改善查找目标索引的准确度，并且就索引的冗余及振荡进行了分析改进，避免在RPV中重复巡查和减小每一次巡查的距离，从而提高查询效率。

| Abstract: | In the JXTA 2.0 reference implementation, policy of publishing and searching index is based on the policy of index fixed distribution. The current loosely-consistent RPV(rendezvous peer view) mechanism should lead to matter of query repeatedly among rendezvous peers. Index dynamic distribution was proposed to improve performance of finding objective index; the redundancy and swing of the index were analyzed and resolved also. It can avoid walking in RPV repeatedly and decrease the distance of every walk, so can achieve a better search efficiency. |
