Configuration of QoS in IP network using Cisco devices
Brož, Kamil ; Šporik, Jan (referee) ; Růčka, Lukáš (advisor)
This bachelor's thesis is divided into two main sections. The first, theoretical section, deals with parameters and requirements of modern real-time applications. This project analyses the particular means of providing QoS. It deals with access in a form of integrated services (IntServ) and with newer access in a form of differentiated services (DiffServ). The chapter covering the Integrated services describes the very basic principles of the problematics. Differentiated services and used algorithms are discussed in detail. The second, practical section, describes the capabilities of Cisco devices and their particular implementation in two designed network scenarios including traffic measurement and user experience tests.

Testing, routing and QoS in private networks
Opravil, Tomáš ; Holík, Martin (referee) ; Škorpil, Vladislav (advisor)
This thesis concerns the interaction of technologies of routing with ensuring the quality of services. It focuses on the function of routing protocols RIP and OSPF in combination with FIFO, PQ and WFQ queues of the technology DiffServ. The main output consists of two complex laboratory tasks. The first deals with theoretical research of the two mentioned above Riverbed programme technologies. The second subsequent task uses the emulator EVE-NG to aim the verification as well as deepening the acquired theoretical knowledge in practise.

Influence of Traffic Management Parameters Settings on Efficiency of DiffServ Technology
Ludvíček, Pavel ; Skořepa, Michal (referee) ; Hošek, Jiří (advisor)
Main purpose of this bachelor thesis is to understand concepts of Quality of Services system in IP networks with main focus on DiffServ technology and packet classification on boundary routers. DiffServ domain model will be created using OPNET Modeler simulation software. Various scenarios will be created to determine level of influence of individual parameters in DiffServ mechanism to selected network transfer characteristics. Particular mechanisms of packet management will be set as well as various types of queues used in DiffServ technology. Each setting will be tested using simulation in OPNET Modeler and compared using graphs.

New laboratory exercises in OMNeT++ network simulator
Vlašín, Martin ; Polák, Josef (referee) ; Langhammer, Lukáš (advisor)
Diploma thesis deals with creating four laboratory tasks using simulation tool OMNeT++ and Inet Framework extension. Subject matter of these designed tasks is focused on routing protocols, providing quality of service, computer networking technologies used in local area networks and comparison of active networking devices. First task contains the comparison of behaviour and routing techniques between protocols RIPv2 and OSPFv2, including the effect of dividing OSPF network into smaller areas. Second task is focused on various techniques for controlling quality of service, namely FIFO queue, PQ and WFQ. Main goal is the comparison of results, that define quality of network services. Third task compares networking technologies, Ethernet and WLAN, parameters of transmission. Fourth task offers comparison of networking devices, hub, switch and router. This paper also contains required theory of network technologies and software tools used for executing simulations.
