Distributed and Self-organizing Systems (VSR) : Research: Areas: Service Infrastructures

Situation / Problem / Solution requirements

VSR focuses research for Service Infrastructures. This research area addresses important areas of the future internet. The European Commission has said about this:

The current Internet architecture was not designed to cope with the wide variety, and the ever growing number of networked applications, business models, edge devices, networks and environments that it has now to support. Its structural limitations in terms of scalability, mobility, flexibility, security, trust and robustness of networks and services are increasingly being recognised world-wide. The challenge is to comprehensively and consistently address the multiple facets of a Future Internet, with energy efficiency also appearing as an important societal concern. Clean slate or evolutionary approaches or a mix of those can be equally considered. From a networking perspective, this entails a need to rethink architectures such that performance bottlenecks are overcome, a wider variety of service types can be supported, 13 of 134 novel types of edge networks such as wireless sensor networks may be integrated, and constraints imposed by new types of media applications such as 3D virtual environments can be supported. Mobility and ever higher end to end data rates also emerge as important design drivers, and so does security and trustworthiness. At network level, a clear challenge will be to provide the Internet with the flexible and ad-hoc management capabilities that have never been part of the 'best effort' paradigm driving the original design. Novel radio and optical systems are important components of this overall network perspective. These network infrastructures need to support an Internet of dynamically combined services with worldwide service delivery platforms and flexibly enable the creation of opportunities for new market entrant. The 'third party generated service' is emerging as a trend supporting the move towards user-centric services, as shown by the advances in Service-Oriented- Architectures and in service front-ends as the interface to users and communities. Virtualisation of resources remains an important research driver enabling the delivery of networked services independently from the underlying platform, an important issue for service providers. Advances in these domains also require breakthroughs in software engineering methods and architectures addressing complexity in distributed, heterogeneous and dynamically composed environments, as well as non-functional requirements.

Goal

VSR develops technologies under this research challenge. Student projects are expected to be tailored to meet key societal and economic needs.

Data Grid Service external link

The WebComposition/DGS continues the research within the WebComposition field and constitutes the first component of the fourth generation of the WebComposition approach. The WebComposition/DGS addresses the increasing need to store, access, manage and to publish ultra large amounts of data over the World Wide Web using a RESTful approach. The developed component addresses both, complex business-related scenarios as well as requirements in the context of Web2.0. The formal description of system-transcending relations allows furthermore modeling the interaction of different system components.

Web-based Federation Technologies for Science external link

The research project Web-based Federation Technologies for Science (codename "Hanoi") is concerned with the practical application of federated Web technology in real-life scenarios. This covers e.g. single-sign on access across Web sites, inter-organizational use of Web services, or federation management with the help of architecture registries.

Federated System Modeling

Project Nevada is concerned with modeling organization-spanning Web-based systems with respect to federation techniques studied in the context of the Kenya project. As a major subject of research, the WebComposition Architecture Model (WAM) is developed, comprising graphical modeling notations, machine-readable model representations as well as infrastructure services based on the modeling information.

Service Infrastructure Systems for Federated Identity Management external link

The goal of the Kenya project is to provide support by system and support by method for scenarios of federated identities. The support by system includes a software infrastructure to support delegated, decentralized and federated authentication and identity management for the Web by partially implementing specifications on top of specifications like WS-Federation and SAML. The support by method consists of concepts and methods for developing and maintaining distributed systems with identities originating from multiple trust realms.
