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.
