Abstract
Traditional networked file systems like NFS do not extend to wide-area due to network latency and dynamics introduced in the WAN environment. To address that problem, a wide-area networked file system is based on a traditional networked file system (NFS/CIFS) and extends to the WAN environment by introducing a file redirector infrastructure residing between the central file server and clients. The file redirector infrastructure is invisible to both the central server and clients so that the change to NFS is minimal. That minimizes the interruption to the existing file service when deploying WireFS on top of NFS. The system includes an architecture for an enterprise-wide read/write wide area network file system, protocols and data structures for metadata and data management in this system, algorithms for history based prefetching for access latency minimization in metadata operations, and a distributed randomized algorithm for the implementation of global LRU cache replacement scheme.
