Systematic QoS class mapping framework over multiple heterogeneous networks

Abstract

A network defines its own Quality-Of-Service (QoS) class and has QoS support mechanisms. So, effectively to support end-to-end QoS in heterogeneous networks, a certain unified control is needed, however, it causes scalability problem as management complexity and implementation difficulty. There is a strong need to provide simple interoperability with QoS support so we present a QoS Class Mapping (QCM) framework: building blocks should be defined such as parameter mapping and class mapping. And we improve the framework, called as QCM-ASM, to support not only flawless class mapping but also fine-granular QoS in any circumstance. At last, another framework with adaptive QoS Class Selection (AQCS) mechanism, named as AQCM-ASM framework, is proposed. AQCS mechanism can prevent resource starvation of lower priority class and provide an effective resource distribution. As an experimental result, we demonstrate a performance of the proposed frameworks. The performance results show characteristics of each framework. © 2008 Springer-Verlag Berlin Heidelberg.
