一种基于索引P2P分层的网格资源发现模型

Grid resource discovery model based on index P2P layered topology

网格资源发现是网格研究中的重要组成部分,随着P2P网络的兴起,许多新的概念和研究方向为网格研究提供了思路。针对网格环境下集中式和无结构P2P资源发现机制的缺陷,提出了一种基于索引P2P分层的网格资源发现模型,引入了索引P2P分层网络,充分利用了网格环境中节点性能的差异,具有较好的资源查找发现功能,并且对大规模的网格具有较好的适应性。

Grid resource discovery is an importance part of the grid research.New ideas are introduced to grid with the development of P2P system.This paper proposes a new resource discovery model based on index P2P layered topology.This model introduces an index P2P layered topology which can alleviate the deficiency of centralized and non-structured P2P resource discovery mechanism in grid environment.Performance of the model in highly dynamic environment is analyzed and tested.It shows that the searching,routing,indexing and query transmitting ability of the model are greatly improved.
