Abstract
The evolution of the Andrew File System (AFS) into a wide-area
distributed file system has encouraged collaboration and information
dissemination on a much broader scale than ever before. In this
paper, we examine AFS as a provider of wide-area file services to over
80 organizations around the world. We discuss usage characteristics of
AFS derived from empirical measurements of the system, and from user
responses to a questionnaire. Our observations indicate that AFS
provides robust and efficient data access in its current
configuration, thus confirming its viability as a design point for
wide-area distributed file systems.
