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.

Chrooma+

Crossmediale Mehrwertdienste für die digitale Mediendistribution

2012/08 - 2014/12

The junior research group Chrooma+ is exploring how to enrich audiovisual media with semantic interlinked information. The project is a cooperation with the professorships Medieninformatik and Technische Informatik. We are focusing our research on Web services, digital signage and interactive television.

MockupDD

MockupDD

2012/01 - 2013/12

MockupDD project intends to combine the high degree of end-user involvement provided by agile methodologies, with the productivity provided by MDWE (Model-Driven Web Engineering). MockupDD uses interface mockups (popular in code-based agile processes) to gather interaction and functional requirements, and then reuses them throughout the whole development process as valuable model specifications. These specifications provide also the foundation required to generate running web applications (even partially) by following an iterative enrichment process. MockupDD intends to be a hybrid agile and model-driven methodology to analyze, design and implement web applications. It promotes intensive end-user participation by incorporating user interface mockups as a common language between them and the development team. At the same time, MockupDD relies in the productivity provided by MDWE methodologies to quickly derive web applications from high-level models.

WebComposition/DGS

Data Grid Service

2007/10 - 2013/07

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.

Research and Development for ARC Solutions

2009/01 - 2009/12

The project is concered with platform-independent access to and control of a product lifecycle management software (Siemens Teamcenter) by using a web service interface.

GIG-E-Vision

Research and Development for GIG-E-Vision / BGAPI

2007/08 - 2009/08

The project focuses research and development of drivers and platform-independent applications for the GIG-E-Vision standard. GIG-E-Vision allows the connection of cameras and computers via Gigabit-Ethernet.

Hanoi

Web-based Federation Technologies for Science

2007/04 - 2008/12

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.

Nevada

Federated System Modeling

2005/01 - 2007/10
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.

BMS

Bildungsmarkt Sachsen

2003/01 - 2007/07

The BMS project deals with the conception, development and operation of an education information system in the form of a Web portal. The mission of this portal is to provide unified access to educational offers within the Free State Saxony. Project activities also involve the creation of interfaces for the exchange of data between multiple institutions and enterprises.

AriPhone

Java-SIP-Phone

2006/12 - 2007/05

AriPhone is a Web-based SIP-Phone that works as a Browser applet. The implementation is based on the Java-WebStart-Technology.

Kenya

Service Infrastructure Systems for Federated Identity Management

2003/11 - 2007/04
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.

L:Aus 2

Lehrveranstaltungen: Anmeldungen und Scheine, Version 2

2006/01 - 2007/01

Project L:Aus is concerned with the design and implementation of a Web-based tool for teaching event management. The system is currently in use for the faculty of computer science and provides features like online course registration or seminar work assignment.
