Fragment Maintenance in Distributed Storage Systems

摘要：

How to efficiently enhance fault-tolerance and data access availability are the major problems to solve in distributed storage system. Data fragment maintenance is an essential part of distributed storage systems. Byzantine quorum system is a typical system model in maintaining data availability. The paper presents a novel fragment verifying and repairing algorithm built in Byzantine quorum system with the mechanism of fragment verifier generation and recovery. Different data redundancy schemes are considered when applying our algorithm. According to our analysis, the algorithm can greatly reduce computing complexity and network load in probing and returning an available quorum. More importantly, processing simplification is considered.
