传统的网格资源发现系统采用集中式或者层次化的结构,但这些结构不能满足网格系统规模不断扩大的需求。而P2P系统是一种扩展性好的分布式系统,采用已有的P2P技术解决网格环境下的资源发现问题是一种有效的途径。简要介绍了目前采用P2P技术解决网格资源发现的问题,提出了一种采用超级节点模型和资源主动声明机制相结合的资源发现方法,并给出相应的算法描述,最后验证了其有效性。
Traditional grid resource discovery systems use centralized or hierarchical structures, but these structures can not meet the expanding needs of grid systems. However, P2P system is a distributed system with good scalability. It is an effective way to solve the problem of resource discovery in grid environment by using the existing P2P technology. A brief introduction to the current problem of using P2P technology to solve the problem of grid resources discovery is proposed. A resource discovery method based on super node model and active resource declaration mechanism is proposed. The corresponding algorithm description is given and its validity is verified.
