all there.

Talk Title: Policy Analysis for DiffServ Quality of Service Management

Abstract:
Policy-based management provides the ability to (re-)configure 
differentiated services networks so that desired Quality of Service 
(QoS) goals are achieved. This requires implementing network 
provisioning decisions, performing admission control, and adapting 
bandwidth allocation to emerging traffic demands. A policy-based 
approach facilitates flexibility and adaptability as policies can be 
dynamically changed without modifying the underlying implementation. Yet 
despite various research projects, standardization efforts and 
substantial interest from industry, policy-based management is still not 
a reality. One of the reasons behind the reticence to adopt this 
technology is that it is difficult to analyze policies in order to 
guarantee configuration stability given that policies may have conflicts 
leading to unpredictable effects.

The talk will describe a comprehensive set of QoS provisioning policies 
from service management to traffic engineering, classify inconsistencies 
that may arise between them, and provide an overview of the methodology 
developed for their analysis.
