The performance of AF service in multi-DS domain networks

There are many research papers concerning the performance of Assured Forwarding (AF) service in a single Differentiated Services domain network. However, few works have dealt with the performance evaluation of architectures that are based on interconnected AF service domains. The paper presents a simulation based performance study of the AF service in a multi-DS domain network architecture. This was motivated by the fact that in the real world, communication systems are often composed of many interconnected domains. We also give a comparison of the performance of AF service in single- versus multi-DS domain networks.
