Modeling and Simulation of BGP
Novák, Adrián ; Marek, Marcel (referee) ; Veselý, Vladimír (advisor)
This Master's thesis deals with modeling and simulation of BGP protocol within the OMNeT++ environment. The BGP protocol is described with employed data structures and the finite state machine of BGP peering. Next, the basic configuration is outlined involving the setup of the BGP protocol on Cisco devices. Further, BGP for OMNeT++ state-of-the-art is investigated together with its lack of functionality and issues. The second part of this thesis deals with design, implementation, and testing of the new functionality of BGP protocol and simulation models. The last section describes the overall achieved results.

Implementation of OSPFv3 for INET4
Galbička, Lukáš ; Marek, Marcel (referee) ; Veselý, Vladimír (advisor)
This thesis deals with simulation of routing protocol OSPF in simulation software called OMNeT++. OMNeT++ is a discrete modular simulator mostly used for simulation of computer networks. This thesis includes theory needed for an understanding of the functionality of OSPFv2 and changes in OSPFv3 for IPv6, which are implemented in the model itself. Moreover, thesis contains the configuration of OSPFv3 protocol on topology created from Cisco devices following by analysis of previous source files, state of implementation and its further extension. Thesis is finished with functionality testing and evaluation of results.

Comparison of Link-State Routing Protocols
Zavřel, Jan ; Marek, Marcel (referee) ; Veselý, Vladimír (advisor)
This thesis deals with a comparison of two dynamic link-state routing protocols OSPF and IS-IS. These protocols are used to route within one autonomous system under control of one administrative entity. They are similar in theory but IS-IS seems to be much more popular in large topologies in practice. Goal of this thesis is to figure out how their properties and features manifest on given topologies on real routers and in simulations. Simulations are realized in discrete simulator OMNeT++ and real topologies are built with Cisco devices. Primary measured parameters are speed of convergence, bandwidth usage and message order. The simulation result may be affected by their implementation in INET and ANSAINET frameworks. Implementation properties of OSPF and IS-IS on Cisco devices are compared to their simulated counterparts in order to verify functionality of the simulation models.

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.

Modelling of L2 Management Protocols
Rajca, Tomáš ; Marek, Marcel (referee) ; Veselý, Vladimír (advisor)
This thesis deals with modelling and simulation of management protocols on the data-link layer in OMNeT++ tool. Namely protocol CDP, LLDP and ODR routing. These protocols are described in the first thesis' half and in the second half is described their design and implementation in ANSA project. Correctness of implementation is verified by comparison between simulated and real network examples. Also dependencies on module DeviceConfiguratoru were removed from ANSAINET library.

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.

Simulation of EIGRP Protocol Behavior Using OMNeT++
Tlolka, Martin ; Matoušek, Petr (referee) ; Ryšavý, Ondřej (advisor)
The present thesis deals with the analysis of EIGRP routing protocol for the purpose of integration of EIGRP simulation model in OMNeT++ environment. Protocol EIGRP defined by Cisco Systems is proprietary, which represents an obstacle in the implementation of a simulation model. In the present work, the description of a behavior of the protocol resembled from available information sources is given and then refined according the results obtained from experiments done with real network devices. The contribution of the work consists of a description of protocol behaviors in basics situations and the identification of properties that the simulation model should comply with.

IPv6 Modelling in OMNeT++
Černý, Marek ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
OMNeT++ is a discrete-event simulator commonly used to build various network simulations. It can be extended by INET framework that supplies models of protocols and devices from TCP/IP environment. This paper explores current capabilities of INET to model IPv6, particularly routing. Implemented extension includes modules of dual-stack router and dual-stack host that support XML-based configuration of IPv6 addressing and static routing. We also introduce an OSPFv3 module that implements most of auxiliary features and is ready for future development of the routing protocol core.

Dynamic State of OMNeT++ Model via SNMP
Smejkal, Jakub ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
This work outlines ways of getting dynamic state into OMNeT++ model. SNMP as major technology was selected for reaching the goals. Protocols CDP and LLDP are participating in topology detection and in theoretical layer Breadth- first search is used. The output of this tool is file syntactically specied by NED language which is describing computer network.
