DCE Distributed File System [SEP] based on
DCE Distributed File System
The DCE Distributed File System (DCE/DFS) is the remote file access protocol used with the Distributed Computing Environment. It was a variant of Andrew File System(AFS), based on the AFS Version 3.0 protocol that was developed commercially by Transarc Corporation. AFS Version 3.0 was in turn based on the AFS Version 2.0 protocol (also used by the Coda disconnected file system) originally developed at Carnegie Mellon University.
DCE/DFS consisted of multiple cooperative components that provided a network file system with strong
Kerberos as the security server, LDAP for the CDS and the Network Time Protocol implementations for the time server.
While it is possible to implement a distributed file system using the DCE underpinnings by adding filenames to the CDS and defining the appropriate ACLs on them, this is not user-friendly. DCE/DFS is a DCE-based application which provides a distributed filesystem on DCE. DCE/DFS can support replicas of a fileset (the DCE/DFS equivalent of a filesystem) on multiple DFS servers - there is
