Autonomic network platforms aim to solve the shortcomings of traditional static network technologies by enabling the capability to evolve. They propose a functional alternative to current infrastructures whereby applications do not need to conform to the limitations of the network, but the network does its best to optimise itself to application requirements(More)

Anomaly detection in communication networks provides the basis for the uncovering of novel attacks, misconfigurations and network failures. Resource constraints for data storage, transmission and processing make it beneficial to restrict input data to features that are (a) highly relevant for the detection task and (b) easily derivable from network(More)
A broad spectrum of network measurement applications demand passive multipoint measurements in which data from multiple observation points has to be correlated. Examples are the passive measurement of one-way delay or the observation of the path that a packet takes through a network. Nevertheless, due to high data rates and the need for fine granular(More)

We introduce a charging and accounting (CA) architecture for IP multicast services with QoS guarantees over ATM for QoS-sensitive fair charging. The architecture is based on an extension of the Multicast Integration Server (MIS, [SaCS97]) that efficiently provides IP multicast over ATM, supporting Internet Integrated Services (IS) with receiver(More)
In this paper we propose a layered framework for charging QoS-enhanced IP services with policy based configuration of its layers. As an example architecture we present our implementation-Value Added IP Charging and Accounting Service (VIPCAS). We further concentrate on VIPCAS elements for policies and data exchange. As flexible data structure for exchange(More)
