An integrated IP QoS architecture - performance

In this paper, we discuss empirical, analytical and simulation-based performance studies for an integrated IP QoS architecture implementing QoS resource management over a heterogeneous wireless and wireline network. The integrated IP QoS architecture is based on Assured Forwarding (class-based) Differentiated Services and admission control of individual flows into each service class by a centralized server, called the Bandwidth Broker (BB) managing the network. The results we present in this paper are used as guidelines in designing the capacity estimation algorithm for admission control and optimizing QoS resource management within our integrated IP QoS architecture. These results serve as an instrument to understanding how to perform effective QoS resource management, using class-based Differentiated Services and admission control to guarantee class-appropriate end-to-end QoS over IP networks.
