Laboratory of computer networks

Laboratory of computer networks, converged systems and complex IT systems

Science and research and teaching laboratory. Research conducted in the laboratory of computer networks, converged systems and complex ICT systems concern a wide range of issues in the field of design and operation of complex communication systems, including effective and trouble-free data transmission in the environment of ICT networks. The laboratory conducts research in the area of: network traffic analysis, its properties and impact on network infrastructure; analysis of long-term processes occurring in computer networks; research on mechanisms of load balancing and maintaining the reliability of network infrastructure, as well as ensuring the resistance to damage of network structures carrying out data transmission in critical infrastructures; automating the process of managing distributed systems, optimizing the use of elements of the transmission system (eg tolerance of damage, load balancing). The laboratory also performs tasks in the design and configuration of network infrastructure based on both a homogeneous and heterogeneous environment of computer networks. As part of the work, various configuration scenarios are tested based on widely accepted standards and network protocols as well as proprietary and newly created mechanisms and network solutions. The scope of work and exercises relates both to issues related to Enterpise class networks, operator networks, as well as industrial ones used, among others in Industry 4.0 and energy. Laboratory equipment also allows you to test ready-made solutions before implementing them for production or operation in the proof of concept scenario. Most of the laboratory equipment is also used by students during classes, during the preparation of diploma theses and during student internships.

In addition to the network equipment of the leading manufacturers, there are software and hardware traffic generators, motion analyzers and simulation platforms (eg Riverbed Modeler, Omnet). Researchers and students have also prepared computer stations, structural cabling (copper and fiber), auxiliary servers and private cloud resources. The wide range of available equipment also allows work to be carried out in cooperation and for industry.
