摘要

复制式分布式文件系统是为了在多台机器上可靠地存储大型文件而设计的，它引起了为客户端选择最近副本的问题。本文提出了一种基于网络坐标(Network Coordinates, NC)的最近副本选择服务Rigel，它是一种可扩展的、轻量级的为客户端选择最近副本的有效基础架构。我们的模拟结果表明，与Hadoop分布式文件系统中的副本选择策略相比，Rigel至少可以将客户端和副本之间的读取延迟减少20%。

Rigel: A Scalable and Lightweight Replica Selection Service for Replicated Distributed File System

Replicated distributed file systems are designed to store large file reliably across lots of machines, and it arouse the problem of selecting the nearest replica for clients. In this paper, we propose Rigel, a Network Coordinates (NC) based nearest replica selection service, which is an effective infrastructure to select the nearest replica for client in a scalable and lightweight way. Our simulation results have demonstrated that Rigel can at least reduce the read latency between clients and replicas by 20% when compared to the replica selection strategy in Hadoop Distributed File System.
