可用性感知的连续网络布局问题

Availability Aware Continuous Replica Placement Problem

Abdullah Yousafzai, Abdullah Gani, Rafidah Md Noor

摘要:

一种数据放置(RP)方法,用于在分布式系统的节点上产生一组重复的数据项,以优化容错、可用性、系统性能和负载均衡。通常,RP公式采用动态的方法来改变系统中的副本放置潜在的用户请求配置文件。连续副本放置问题(CRPP)是副本放置问题的一种扩展,它考虑了分布式系统的当前复制状态以及用户请求配置文件,根据优化准则和约束条件定义新的复制方案。本文提出了一种替代技术,命名为可用性感知的连续副本放置问题(AACRPP)AACRPP可以被定义为:给定一个已经定义的副本放置方案,用户请求配置文件,和节点故障配置文件定义一个新的复制方案,受到优化标准和约束。在这项工作中,我们使用修改后的贪婪算法从CRPP和研究所提出的机制,使用跟踪驱动的Java为基础的模拟。

英文摘要:

Replica placement (RP) intended at producing a set of duplicated data items across the nodes of a distributed system in order to optimize fault tolerance, availability, system performance load balancing. Typically, RP formulations employ dynamic methods to change the replica placement in the system potentially upon user request profile. Continuous Replica Placement Problem (CRPP) is an extension of replica placement problem that takes into consideration the current replication state of the distributed system along with user request profile to define a new replication scheme, subject to optimization criteria and constraints. This paper proposes an alternative technique, named Availability Aware Continuous Replica Placement Problem (AACRPP).AACRPP can be defined as: Given an already defined replica placement scheme, a user request profile, and a node failure profile define a new replication scheme, subject to optimization criteria and constraints. In this effort we use modified greedy heuristics from the CRPP and investigated the proposed mechanism using a trace driven java based simulation.
