| 摘 要： | P2P与网格都是新型的分布式计算模型,在分析现有网格动态资源发现机制的基础上,将P2P的相关技术引入其中,提出了一种基于DHT的网格动态资源查找算法.该算法结合DHT技术和泛洪式查找技术,在实际的分布式网络之上建立一层结构化的Overlay层.实验结果表明,当用户需要在系统中获取信息时,通过该查找算法,查询只在一些特定的结点上进行,这样就避免了泛洪式查找的盲目性,因此大大提高了信息搜索的效率.

| Abstract: | P2P and grid are new-style distributed computing models.Based on the analysis of dynamic resource search mechanisms in grid system,the technique of P2P is introduced in this thesis,and a DHT-based dynamic resource search algorithm in grid environment is proposed.The algorithm constructs the structural overlay layer above the distributed network by means of combining DHT technique with flooding technique.The analysis shows that query is only performed on some specific nodes in this algorithm while users obta... |
