In this paper, we propose a system based on partial replication what has a lower cost of resource than those based on full replication. 文中首先提出一个基于部分复制的容忍入侵系统,可大大降低基于完全复制所带来的系统资源的浪费;
In mobile environment especially mobile ad hoc environment, mobility, disconnections, weak connectivity, resource scarcity, diversity of networks together bring big challenges when designing a data replication system. 在移动环境尤其是移动adhoc环境中,移动性、断连接性、弱连接性、资源的局限性、以及网络情况的多样性都给复制系统的设计带来了挑战。
Thirdly, proposing a graph model of the resource dynamic replication strategy. 提出了网格中资源动态复制的图模型。
Fully analyzed the whole architecture design and module partition of the SAN-based storage resource management system, described the functional description to each frame constituent part in detail and explained the relationship of Replication/ Restore module and the whole storage resource management system. 研究了SAN环境下的存储资源管理软件(SRM)的基本构成和模块划分,对各个框架构成部分进行了详细的功能描述,分析了备份恢复管理与整个存储资源管理系统的关系。
During the past one year, the author took part in a SAN-based storage resource management project and worked on the Replication/ Restore module. 作者在一年多的时间内参与了一个基于SAN的存储资源管理系统(SRM)服务器端的设计与开发,并在其中主要负责备份恢复管理模块。
As mobile learning is a typical mobile computation, it adopts Tree-Tier Replication Architecture in resource base model, then designs the air replication model and mobile client caching model which is suitable for the characteristic of mobile learning. 移动学习作为典型的移动计算,其资源库采用了三级复制体系结构,并设计了适合移动学习特点的空中复制模型和客户机缓存模型。
First, in the level of code, we reduced the number of logic units through resource sharing, removed a number of redundant bits of comparative statement by s suitable description which can reduce the cost of comparison logic, and improved the delay by resource replication. 首先,在代码级,通过资源共享减少逻辑单元的数量;通过剔除多位比较判断语句的冗余位,减少比较逻辑的代价;通过资源复制均衡重负载逻辑,改善了关键路径延时。
Assistant locating requiring processing mainly utilizes resource replicas to reduce locating latency. However, how to balance the performance and replication overhead and how to keep consistency of resource replica in the dynamic P2P systems are still demanding. 辅助定位信息处理技术主要利用资源备份策略来减少定位延迟,但是如何提高定位性能,如何在动态性强的P2P系统中更新资源备份并保持信息的一致性也成为亟待解决的问题。
However, data management is more complicated in the MANET that has such basic characteristics as self-organization, mobility, multi-hop and limited resource. Therefore the research on data replication for MANET is quite challenging. 移动自组网络由于其自组性、移动性、多跳性、资源有限性等特点使数据复制技术面临新的挑战。
Focused on the problem that the data related to replication technology of existing discovery mechanism not only occupies large storage space, but also inapplicable for hierarchical structure, this paper put forward a resource discovery mechanism based on the local index information replication technology. 针对现有资源发现机制中复制技术引起的数据占用存储空间大且不适用于层次式网络结构的问题,提出了基于本地索引信息复制技术的资源发现机制。
