Ficus is a flexible replication facility with optimistic concurrency control designed to span a wide range of scales and network environments. Optimistic concurrency control provi...
Optimistically replicated systems provide highly available data even when communication between data replicas is unreliable or unavailable. The high availability comes at the cost...
Replication is a key strategy for improving locality, fault tolerance and availability in distributed systems. The paper focuses on distributed file systems and presents a system ...

We develop a consistent mutable replication extension for NFSv4 tuned to meet the rigorous demands of largescale data sharing in global collaborations. The system uses a hierarchi...
Replicated file-systems can experience degraded performance that might not be adequately handled by the underlying fault-tolerant protocols. We describe the design and implementa...
—Peer-to-peer (P2P) file sharing systems are becoming increasingly popular due to their flexibility and scalability. We propose a new model to design file replication schemes ...
