Complex Event Processing (CEP) is the method of choice for the observation of system states and situations by means of events. A number of systems have been introduced that provide CEP in selected environments. Some are restricted to centralised systems, or to systems with synchronous communication, or to a limited space of event relations that are defined in advance. Many modern systems, though, are inherently distributed and asynchronous, and require a more powerful CEP. We present Cordies, a distributed system for the detection of correlated events that is designed for the operation in large-scale, heterogeneous networks and adapts dynamically to changing network conditions. With its expressive language to describe event relations, it is suitable for environments where neither the event space nor the situations of interest are predefined but are constantly adapted. In addition, Cordies supports Quality-of-Service (QoS) for communication in distributed event correlation detection.

in 2007. He is now a research assistant and PhD candidate at Technische Universität München. His research interests center around network security, with a focus on cryptographic protocols and security in massively distributed systems. Together with Dirk Haage, he developed CLIO/UNISONO in the course of the SpoVNet project. AbstractOverlay networks and distributed services are currently favorite approaches to add new functionality to the network. Often, these approaches strongly rely on accurate information about the current state of nodes and network to increase performance, efficiency and user experience. Based on previous work, we show how UNISONO provides this information while hiding the complexity of the measurement task. UNISONO is a generic framework for host-based distributed network measurements. In this paper, we present UNISONO as a way towards consolidated measurement for the creation of overlays as well as for service placement. We give an overview of the UNISONO concept as well as security considerations of such a service and show how distributed services benefit from its usage.

a visiting researcher at University of Toronto. His research interest include overlay-networks in nextgeneration communication systems as well as modeling and analysis of spontaneous, self-organizing systems. AbstractDeveloping new network services in the Internet is complex and costly. This high entrance barrier has prevented new innovation in the network itself, and stuck the Internet as being mainly browser-based client/server systems. End-system based decentralized services are cheaper, but have a complexity several orders of magnitude higher than centralized systems in terms of structure and protocols. To foster development of such decentralized network services, we present the ariba framework. We show how ariba can facilitate development of end-system based decentralized services through self-organizing service overlays-flexibly deployed purely on end-systems without the need for costly infrastructure.
