Instituto de Telecomunicações, Universidade de Aveiro

We are pleased to announce the presence of the distinguished lecturer, Prof. Dr.-Ing. Stefan Wesner, who will visit us at the Instituto de Telecomunicações, in the Universidade de Aveiro Campus. The title of the presentation is:

“BelWü – A High Speed Network Supporting a State Wide Secure Cloud Infrastructure”

The region of Baden-Württemberg operates its own dark fibre based research network currently connecting 9 universities, more than 40 universities of applied sciences and other non-profit organisations such as cultural institutions or schools between each other and to the Internet. BelWü has just completed a major upgrade of its optical infrastructure from a static optical network towards a dynamic and flexible ROADM based solution and will upgrade  its IP layer accordingly connecting the universities with redundant 100Gbps.
The network evolution is driven by a regional service provision concept across the universities supporting cross-organisational services such as compute clouds, long term archiving, high performance computing services but also common IT services such as the library management system.
Technology choices and challenges with a 100Gbps connectivity have been investigated within the bwNET100G+ and bwCloud Projects bringing together the network operation centre of BelWü, the computing centres of the nine universities and researchers in the region specialised in relevant fields such as high speed transport protocols, security solutions at high speeds, software defined networking and Cloud computing.
This talk will outline the technological evolution of BelWü in 2017 and how the regional service provision (using bwCloud as an example) and technology evaluation projects such as bwNET100G+ supported technological choices.


Prof. Dr.-Ing. Stefan Wesner is the director of the Communication and Information Centre (KIZ) and the institute for Organisation and Management of Information systems (OMI) of the University of Ulm. Furthermore, he is the scientific chairman of the research network ISP connecting the 9 state universities and 40 applied research schools in the region. He has been actively participating in research projects on national and international level since 1997, focusing in particular on distributed systems and improving programmability and usability of large scale systems.
His research interests are currently focused on intelligent and adaptive execution environments for next generation of Cloud infrastructure systems. This covers in particular Multi-Cloud solutions and integration of Cloud and Software Defined Networking in wide area networks. Furthermore his group is working on efficient programming of heterogeneous computing systems.
