在结合网格与P2P网络技术优势的基础上,提出一种在网格环境下基于P2P技术的覆盖网络构建机制.该机制对传统的P2P网络资源管理协议Chord进行改进,并根据节点对系统贡献的大小决定其资源管理的权限,实现大规模网格中不同虚拟组织间异构资源的整合,旨在进行有效的资源管理,消除集中式的网格环境下单点失效和系统性能瓶颈的问题.实验结果表明,该机制在使得网格系统获得良好性能的同时,也保持了P2P网络的动态性与网络规模的可缩放性.
Based on the advantages of grid technology and P2P network technology, this paper proposes a new overlay network construction mechanism based on P2P technology in grid environment. This mechanism improves the traditional P2P network resource management protocol Chord, and according to the node contribution to the system The size of its resource management authority to achieve large-scale integration of heterogeneous resources between different virtual organizations in order to carry out effective resource management, centralized grid environment to eliminate a single point of failure and system performance bottlenecks The experimental results show that the proposed scheme not only keeps the grid system in good performance, but also keeps the dynamic of P2P network and the scalability of the network scale.
