Summary

In order to facilitate a cost-efficient operation of QoS-providing IP networks, the future QoS control mechanisms have to be realized in a more autonomous way than today. The concept of Autonomic Computing (AC) has recently gained tremendous attention in the industry. Autonomic Computing is an approach towards self-managed computing systems with a minimum of human interference. AC comprises four functional domains: self-configuration, self-optimization, self-healing, and self-protection. In this project we take the self-optimizing concept of AC and extend it to the idea of autonomic QoS monitoring in IP net-works. The goal is to have a self-organizing management overlay of Distributed Network Agents (DNAs) for distributed service surveillance.

The main objectives are:

Specification of a distributed, self-organizing and autonomic IP QoS monitoring framework which is based on Distributed Hash Tables. The specification includes a QoS feed-back interface for service providers.
Evaluation of the performance of the peer-to-peer mechanisms for maintaining the monitoring overlay. The mechanism has to be investigated with respect to its scalability and reliability under stochastic conditions, i.e. with regard to the non-deterministic behaviour of the transport network and the end users.
Analysis of applicability and accuracy of generic end-to-end performance metrics with regard to user-perceived Quality of Service.
Implementation of a concept demonstrator by the participating SME which uses the .net environment in order to show the commercial viability of the approach.

Voice-over-IP (VoIP) telephony becomes more and more popular in the wired Internet because of easy-to-use applications with high sound quality like Skype. UMTS operators promise to offer large data rates which should also make VoIP possible in a mobile environment. However, the success of those applications strongly depends on the user perceived voice quality. In this paper, we therefore analyze the achievable and the actual quality of IP-based telephony calls using Skype. This is done performing measurements in both a real UMTS network and a test environment. The latter is used to emulate rate control mechanisms and changing system conditions of UMTS networks. The results show whether Skype over UMTS is able to keep pace with existing mobile telephony systems and how it reacts to different network characteristics. The investigated performance measures comprise the Perceptual Evaluation of Speech Quality (PESQ) to evaluate the voice quality, the packet loss, the inter-packet delay, and the throughput to capture networkbased factors. In this context, the concept of the Network Utility Function (NUF) is applied to describe the impact of the network on the voice quality as perceived by the end-user.
