Vertically Integrated Optical testbed for Large Applications

In addition to the ever-growing demand for bandwidth in the Internet, new types of applications with extreme communication demands are evolving, e.g. in the areas of Virtual Reality and Grid-Computing. These applications often require short-term dynamic provisioning of high bandwith and Quality-of-Service. Such demands cannot be fulfilled by todays production networks. The project VIOLA addresses these issues by setting up an optical testbed in the area of North-Rhine-Westfalia with an extension to Bavaria. In a vertically integrated approach, a consortium with partners from from industry, research laboratories, universities and the DFN association deploys and evaluates advanced networking equipment and developes middleware and applications that make use of the novel testbed features and serve to stress-test the network.

The major goals of VIOLA are:

  • Test of advanced network equipment and network architectures.
  • Development and test of software tools for the user-driven dynamical provision of bandwidth.
  • Interworking of network equipment from different manufacturers.
  • Enhancement of middleware and deployment of a production Grid in support of the applications.
  • Enhancement and test of new advanced applications (e.g. Grid, Virtual Reality).
  • Cooperation with similar projects in Europe and elsewhere.

The VIOLA Consortium contains 10 partners and three associated partners from German industry, research laboratories and universities:
