On providing a Dynamic QoS Management system for IP networks

Abstract

This paper discusses the design of a network management system that supports QoS in IP networks. The proposed architecture, namely QMTool, uses the evolving Differentiated Services paradigm and provides end-to-end QoS for IP based applications. The novel aspects of the proposed approach rely on the integration of a collection of mechanisms including QoS provisioning for different types of traffic, flow level admission control and resource management mechanisms that interact with the routers of a network. We focus our attention on the dynamic aspects of QoS management, which is achieved by introducing a set of new technologies. The concept of the proposed management system is described in detail followed by notes of implementation issues
