Abstract :
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.
