Administrative Policies to Regulate Quality of Service Management in Distributed Multimedia Applications

摘要

Properly capturing and handing administrative requirements for Quality of Service (QoS) management is a challenging, infrequently studied, problem. In this paper, we formalize administrative requirements as administrative policies, and use policy-based management techniques for enforcing them. Doing so adds a great deal of flexibility and power to QoS management. We discuss our general policy-based approach to QoS management, provide several examples of administrative policies, and present highlights from the use of a prototype policy-based QoS management system that uses administrative policies in a variety of experiments with a distributed multimedia application.
