About lab

SAGElab  is a joint laboratory of CESNET, the Faculty of Information Technologies and the Faculty of Electrical Engineering at the Czech Technical University. The goal of the laboratory is to support education and research in network and visualization technologies, development of new kinds of applications and experimental work in these areas. The laboratory is used by students and employees for their research work and thesis preparations in collaboration with institutions in Czech Republic and abroad. Local and remote lectures of experts in various fields of research take place in the laboratory opened to public.

CESNET builds a national e-infrastructure for universities and research institutions comprising a high-speed network, computing and storage facilities and distance collaboration tools. To achieve this goal, collaboration with universities, research institutions and educating new experts in the related areas is necessary. Therefore, CESNET has signed a Memorandum of collaboration with the Faculty of Information Technologies at the Czech Technical University. The core of the laboratory was created under a research grant supported by CESNET development fund no. 464/2012. The laboratory equipment and its research activitites have been since than continuously extending.

The laboratory is equipped with a large-scale visualization wall connected to a high-speed network. The current resolution is 8K+ (9600 x 4320 px), created by ultra-narrow-bezel LCD panels. The wall is driven by SAGE/SAGE2 software, allowing to work with multiple local or remote applications simultaneously. The laboratory also provides additional equipment to support research, development and education in computer networks, human-computer interaction.
