Design and implementation of the Sun network filesystem

The Sun Network Fllesystem (NFS) provides transparent, remote access to mesystems. Unlike many other remote rllesystem implementations under UNIXt, the NFS is designed to be easily portable to other operatin& systems and machine architectures. It uses an External Data Representation (XDR) specification to descnoe protocols in a machine and system independent way. The NFS is implemented on top of a Remote Procedure Call package (RPC) to help simplify protocol definition, implementation, and maintenance.
