关于副本定位数据复制新技术的设计

随着计算机网络技术的不断发展,数据网格中副本定位对于网络性能的改进逐渐被人们所认识。本文基于对副本定位数据复制技术的研究,确定了副本创建网格环境后,建立了新技术的域内副本定位机制,提出了动态均衡映射技术域间动态均衡副本定位的方法,完成了系统副本定位模块功能的设计。测试表明,改进的技术数据网格中,域间定位数据元的增加对宿主节点的负载分配没有太大的影响。这一结论对发展大规模网格系统具有重要意义。

Technology Design of One Kind of Replica Location Data Replication

With the continuous development of computer network technology, data grid replica location for improved network performance has been gradually recognized, the paper based on the replica location data replication technology research mainly done the following tasks： created a grid to determine the copy environment, the design of new technologies within replica location mechanism, designed a dynamic equilibrium inter-domain mapping technique dynamic equilibrium replica location method, completed copy of positioning module system design features. Results showed that improved technology for inter-domain data grid positioning data element increased, the load distribution on the host node was not significantly affected, and this conclusion for the development of large-scale grid systems is important.
