The qosip research group joins together academic workers and students of the Department of Telecommunications, FEEC, Brno University of Technology dealing with topics of quality of service (QoS) support in fixed and wireless network technologies. We are interested mainly in QoS support mechanisms operation on the network (DiffServ) and data link layer (Ethernet, WiFi, WiMAX). Within our work we make mainly use of the advanced features of the OPNET Modeler simulation environment and additionally also the active network elements available in our Laboratory of modern network technologies.


If you are interested in the field of our activities, feel free to contact us. We are open for every type of cooperation.

Network Optimatization for Interactive Telemedicine Services

In medical environment, there is a fundamental demand to transfer and store large volumes of image data generated by modern medical devices and interactive telemedicine services. Currently the majority of the medical facilities spread around the country have quite limited Internet access, so these facilities require additional observation and network optimization for transfer of high load traffic generated...

Integration of Real Network Components into OPNET Modeler Co-s...

The OPNET Modeler is a simulation environment enables modeling of large-scale networks with in detail defined parameters. This paper is focused on the possibility to communicate with external systems and applications that this environment offers. Due to this we are able to interconnect simulation environment with real network system and gain the simulation results more accurate and in accordance with the re... Read more

The Simple Network Management Protocol is themain protocol for monitoring and configuring network devices,but it is not the only way of utilizing this protocol. With the helpof this tool, additional information about network devices can beobtained. This information can be used, for example, in theQuality of Service support system that is described in this paper.In order t... Read more
