Advanced Segmentation of a Simulated Network
Slávik, Mark ; Komosný, Dan (referee) ; Benedikt, Jan (advisor)
The diploma thesis deals with the simulation of available routing protocols in the NS3 simulator and in the Quagga module. The functions of simulated routing protocols are described in the theoretical part. In the practical part, the functionality of the NS3 simulator and the RIP, OLSR and OSPF, BGP routing protocols from the Quagga module are introduced using a simple topology. Finally, the network is extended and several subnets are added. Using available analysis tools, the network is subsequently analyzed and evaluated with different scenarios.

Modelling and Simulation of Network Design Guides for IP Routing
Rybová, Veronika ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This bachelor's thesis describes simulation of network using tools Packet Tracer and OMNeT++. Models of network are created according to design guides by Cisco company, which use routing protocols RIP, OSPF and redistribution. In order to provide full functionality of models in OMNeT++ it is necessary to implement protocol RIP and redistribution from protocol OSPF to protocol RIP. Practical usage of tools is demonstrated by simulations of accessibility and stability of network. Thesis investigates results of simulations and usage of both tools for simulation of networks. We use design guides, which are destined to design of real networks, and implement protocol according to standard RFC, therefore we suppose that this thesis will have practical usage for analysis and simulation of company's and academical networks.

Simulation and Optimization of Converged Networks Traffic
Turan, Jonáš ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
The aim of this work is to explore and describe possibilities of the network simulator OMNeT++, to create a user guide using this knowledge and make three tasks for computer exercise. In the first part, the principle and functionality of OMNeT++ are described theoretically, there are possibilities and area of focus. User guide can be used for basic understanding of the system. There is a description of the environment, the file composition and the basic operations. Individual tasks are focused on implementing technology DiffServ, RIP and OSPF. The goal of student is to assemble a simulation and learn basic functions of OMNeT++ and then evaluate the results.

Comparison of Distance-Vector Routing Protocol
Cocuľa, Maroš ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
This work deals with comparing the distance vector routing protocols. More accurately, protocols EIGRP, RIP and Babel. The aim is to compare information using the simulation OMNeT++, as well as the physical connection. Part of the work is a detailed description of the protocols, simulator OMNeT++ and the libraries INET and ANSAINET. Finally, we summarized the results of experiments and the comparison of protocols with each other.

Breath monitoring during motion therapy
Koťová, Markéta ; Bubník, Karel (referee) ; Kolářová, Jana (advisor)
This semestral thesis deals with continuous monitoring of pulmonary ventilation during the patients' theraphy and focuses especially on monitoring of their ventilation processes. It is necessarry to detect, monitor and differentiate abdominal and thoracic breathing during the theraphy. This thesis describes the very basic and common method, a spirometry. Next, an overview of more advanced state-of-the-art methods based on both, tactile and proximity principles is given. In addition to that, two recently developed methods by BUT are discussed as well -- a tactile-based measurement similar to blood pressure sensor and a proximity-based measurement method employing TOF cameras. The data acquired by these two methods are proccesed and examined in order to evaluate and justify their performance in a real application.

Fault recovery in data networks
Trávníček, Michal ; Martinásek, Zdeněk (referee) ; Mácha, Tomáš (advisor)
The purpose of the bachelor’s thesis was to explain the basic principles and technologies for ensuring reliable and effective routing within networks when a link failure. This is with minimal effect to the quality of service. The focus was on mechanisms ensuring the quality of services within the network, especially differentiated services and the both groups of dynamic routing protocols – distance vectors and link state protocols. On the basis of obtained knowledge, the simulation has been designed in OPNET Modeler. It simulated routing of routing protocols RIP and OSPF of networks without any failure. The next simulations containted the link failure and the link recovery. Then the network with DiffServ was designed. It filtered data packets according to used ports and protocol and it added a label to packet with a priority for the certain service. The attention in the network was focused on the VoIP service and its parameters, such as jitter and end-to-end delay. It has also monitored the value of dropped traffic. It simulated the networks with the link failure and the link recovery. The results were compared to the network with no QoS and network with QoS but no failure.

Protocol model design in OMNET++ simulator
Vohralík, Jan ; Matocha, Tomáš (referee) ; Novotný, Vít (advisor)
The aim of this Thesis is giving information about the network simulating system OMNeT++ and its extension INET framework and explore possible solution to implement missing protocol RIP. OMNeT++ is a discrete-event simulation environment. Source code is available and free for teaching and research purposes. Its primary application area is the simulation of communication networks, but because of its generic and flexible architecture, is successfully used in other areas like the simulation of complex IT systems, queueing networks or hardware architectures as well. The first part of Thesis decribes RIP protocol operations and conception of OMNeT++. At the second part of Thesis the implementation design and discussion of created modules and component is presented here. The final part of the Thesis was creating the laboratory problem on the basis experience gained. Implementation is realized in C++ programming language.

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.

Routing principles in data networks
Stodůlka, Tomáš ; Burda, Karel (referee) ; Novotný, Vít (advisor)
This bachelor thesis deals with the problem of routing in data networks. The theoretical part defines general options of connections between two nodes. Furthermore, the principles of switching within a single network and routing between the networks are described. Another part of thesis focuses on the routing methods in terms of static or dynamic enrolment into the routing table. In the practical part have been designed and realized a structure and topology of laboratory exercise for subject Architecture of networks.

Laboratory exercises explaining the principles of network technologies and protocols
Hricko, Tomáš ; Jeřábek, Jan (referee) ; Langhammer, Lukáš (advisor)
The aim of this diploma thesis is to create two exercises for students. The first exercise is concerned with comparison of transport protocols TCP and UDP. The second exercise is concerned with comparison of routing protocols OSPF and RIP. The first part describes used simulation environment. The next part describes the operating system used in routers. The following part describes the procedure of installing virtual machines. The next part consists of theory of protocols TCP, UDP, OSPF and RIP. The last two chapters are the laboratory exercises.
