Self-Paging in the Nemesis Operating System
Steven M. Hand
University of Cambridge Computer Laboratory
Abstract
In contemporary operating systems, continuous media (CM) applications
are sensitive to the behaviour of other tasks in the system. This is
due to contention in the kernel (or in servers) between these
applications. To properly support CM tasks, we require "Quality of
Service Firewalling" between different applications. This paper
presents a memory management system supporting Quality of Service
(QoS) within the Nemesis operating system. It combines
application-level paging techniques with isolation, exposure and
responsibility in a manner we call self-paging. This enables
rich virtual memory usage alongside (or even within) continuous media
applications.
