Distributed network storage service with quality-of-service guarantees

摘要

This paper envisions a distributed network storage service with Quality-of-Service(QoS) guarantees and describes its architecture and key mechanisms. When fully realized, this service architecture would be able to support, in one integrated framework, network stor- age services ranging from best-effort caching to replication with performance guarantees. Content owners could, through the use of standardized protocols, reserve network stor- Be able to specify either the number and/or placement of the replicas, or highr-level Performance goals based on access latency, bandwidth usage or data availability.
