Maintaining Redundancy in Peer-to-Peer Storage Systems
Anwitaman Datta, Di Wu, Xin Liu, Adam Wierzbicki · IGI Global eBooks · 2010
Peer-to-Peer (P2P) storage systems leverage the combined storage capacity of a network of storage devices (peers) contributed typically by autonomous end-users as a common pool of storage space to store and share content. A major challenge in such a system comprising of autonomous participants is to guarantee quality of service in terms of persistence and availability of the stored content. This chapter focuses on the different possible design choices for maintaining redundancy in P2P storage systems, including algorithm details of maintenance mechanisms, analytical models to understand system’s dynamics, empirical results from simulation experiments as well as experiences from prototype deployments.
