The Implementation of an Active File System
By Steve Hart, James Nugent, Arman Rouf
Abstract
The Active File System (ACFS) is a concept of file system design that allows
an existing file system to be extended easily and in a secure and efficient
manner. This paper describes the design and implementation of an
Active File System. We first describe our concept of an Active File System
and our goals for such a system. We include a detailed discussion of security
and efficiency. We then describe our implementation of an active file system
and how it relates to our goals. We conclude with some measurements of
our implementation's performance and how it could be extended to a production
system.
