"A Survey on Replica Placement in Wide-Area Distributed Systems"

By Mr. Huicheng Chi


Abstract:

With the widespread installation of content distribution networks (CDNs)
in the Internet, data replication has been used extensively to improve the
accessibility of Web sites. Existing work has focused on request routing
techniques for efficiently redirecting user requests to appropriate
servers. In this survey, we investigate the replica placement problem in
wide-area distributed systems. First, we survey the theoretical background
and introduce a framework to model different issues in replica placement.
In this framework, the replica placement is combined with consistency
management and various quality of services (QoS) issues. Applications to
both fixed-topology Internet and the emerging peer-to-peer (P2P) networks
are discussed. Finally, we suggest a list of promising future research
directions.
