The Computer Networks Laboratory was formed in 1995 as a result of the solution of research tasks and pilot projects in cooperation with the industry. It is a joint contractual research and experimental work station KPI FEI TU and elfa s.r.o. Currently it is a top work station involved in the progressive network technologies in the Slovak Republic and highly appreciated also by the international expert community (during its existence this lab was awarded number of international awards). The main research objective of the lab are computer networks and progressive network infrastructures emphasizing the issue of the information transfer of the multimedia nature with the required quality of services parameters (QoS). Special attention is paid to the following areas: The effective methods of quality service property parameters assessment, Implementation of the powerful streaming technologies in the IP network environment, Videoconference solution and voice services of the new generation, Monitoring, control and visualization of topologies in LAN and WAN, Virtual communication infrastructures and their use in practical (e-learning technologies and their solutions). Based on CNL the first Regional Cisco Network Academy (RCNA) came into being in the Slovak Republic in 1999 providing certified education of the network specialists on the basis of industrial standards effective on the whole territory of the Slovak Republic within the NetAcad Program (Networking Academy) implementation. The lab premises consist of a complex of five rooms with top equipment suitable for provision of teaching in the respective area, but also for extensive specialized and research activities implemented on the lab basis. The lab offers an integrated educational process in the field of information and communication technologies emphasizing the issue of computer networks, their design, administration and management. In the lab premises specialized teaching of courses and events oriented on network technologies and teaching within NetAcad program (network academy program CISCO) is implemented. LPS has university significance currently offering teaching for more than 200 students of the Technical University annually. The lab is built in cooperation with a whole range of other external sponsors, especially Cisco Systems Company. In cooperation with T-com (Slovak Telecom, a.s.) and experimental nod of the WAN network with access to WAN ATM ST, a.s. as the first experimental and training segment on the basis of the ATM technology in the Technical University Campus and the first specialized work station in the Slovak Republic and the Czech Republic for training of network specialists on
