Modelling PIM-SM in OMNeT++
Procházka, Tomáš ; Ryšavý, Ondřej (referee) ; Veselý, Vladimír (advisor)
In this master's thesis I deal with modelling and simulating of multicast routing protocol PIM Sparse Mode in OMNeT++. I also describe basic information about multicast, protocol PIM-SM, its configuration and multicast data streams visualization in computer networks. The thesis is especially focused on design and implementation of PIM-SM in OMNeT++ and extension of ANSAINET library.

Design of IP Multicast Communication Tests
Stehura, Igor ; Matoušek, Petr (referee) ; Švéda, Miroslav (advisor)
This masters thesis is about mutlicast. There are explained 2nd and 3th layers of the ISO/OSI model multicast addressing. Routers in a network use multicast routing protocols to optimally route multicast packet through the network, this is also in this project. These multicast protocols are DVMRP, protocol PIM in his two modes, PIM Sparse Mode and PIM Dense Mode. Protocol DVMRP uses protocol IGMP, which is described as well. At practical section of this masters thesis is presented connections, by which tests was executed.

Architectures of Internet-Based Systems with Multicasting
Veselý, Vladimír ; Matoušek, Petr (referee) ; Švéda, Miroslav (advisor)
With rapid expansion of interest in multimedia and distributed computing applications across the Internet increases importance of optimized delivery of group traffic. According to current situation the best practice to achieve this goal is multicasting. This masters thesis summarizes multicasting methods and facts. Also it draws conclusions from practical application of presented information on commercial project.

Monitoring Application for Multicast sessions
Kopecký, Martin ; Komosný, Dan (referee) ; Šimek, Milan (advisor)
This work deals with a monitoring application for multicast sessions. The general aim is to develop the application for monitoring multicast sessions from network elements of a laboratory computer network. The first part describes possibilities of monitoring computer networks in terms of monitoring techniques and protocols. The second part contains a topology of the laboratory computer network and several basic commands for setting of the multicast in Cisco IOS. The third part is devoted to the developed application for monitoring the multicast in Java language. The last part describes the testing on an actual multicast network and an example of such testing is stated there.

Multicast Routing Modelling in OMNeT++
Rybová, Veronika ; Matoušek, Petr (referee) ; Veselý, Vladimír (advisor)
Multicast traffic is common in today's networks. We need to simulate multicast architecture to be familiarized with its functionality in all situations. This thesis describes modelling and simulation of multicast routing using OMNeT++ tool. The text introduces protocol PIM and its particular modes (DM, SM, SSM, and BiDir) with emphasis on PIM-DM. The thesis focuses especially on design and implementation of OMNeT++ extension by multicast routing protocol PIM-DM. Correctness of implementation is verified by comparison of simulation and real network on example.

Adapting Service Interfaces when Business Processes Evolve
Kudelas, Vladimír ; Nečaský, Martin (advisor) ; Richta, Karel (referee)
In the presented work, we study a derivation of an optimal communication XML schemas for a given conceptual model of a business process, complemented with a conceptual model of exchanged data and influence of a change in user requirements on derived XML schema. The work contains a review of important problems related to the topic. It also describes existing approaches of these problems. The work analyses a derivation of an optimal XML schema in detail. The approach presented in this thesis shows an ability to model exchanged data with a conceptual model of a business process. The thesis describes a solution, how to derive a concrete XML schema automaticly from a given conceptual model of exchanged data. Finally, the work contains a prototype implementation of the presented solution.

The phenomenon of running the example RunCzech races organized by PIM in the period 1995 - 2014
Antalová, Ladislava ; Kaplan, Aleš (advisor) ; Červinka, Pavel (referee)
Title: The phenomenon of running the example RunCzech races organized by PIM in the period 1995 - 2014 Objectives: The thesis aims to briefly capture the phenomenon of running in the Czech Republic and the example of competitive races organized by Prague International Marathon Ltd. (hereinafter PIM) record in quantitative terms gradual increase in the number of candidates running in the period from 1995 to 2014 and also determine the quality level of sports performance enhancing participants in the Prague Marathon. Finally, find out the opinions and attitudes of runners participating in the Prague Marathon on sporting level and organization of the Prague marathon and compare them with the views of the author. Methods: For the dissertation was chosen method of content analysis of the basic documents and print materials, as well as results and information to individual vintages Prague marathon. In the second part, the method of polling in the form of survey questions. To compare the results of the interrogation method was also evaluated using the reflection of the author as regular participants in cross-country races. Results: The results of this thesis show a rise in the number of runners in the Czech Republic, which also corresponds to the global phenomenon that was captured in the case of selected...

Multicast routing
Hlavatý, Ondřej ; Mareš, Martin (advisor) ; Knop, Dušan (referee)
We implement multicast routing in the BIRD routing daemon. At first, we review basic principles of IP multicast and different modes of the PIM multicast routing protocol. Then we outline the architecture of the BIRD and discuss its aspects related to our goal. We present our solution based on adding IGMP, bidi- rectional PIM, and kernel interface as three separate BIRD protocols. Finally, we describe our framework for testing network software in complex virtual networks.
