Modelling OSPF Routing Protocols Using OMNeT++ Simulator
Danko, Martin ; Matoušek, Petr (referee) ; Ryšavý, Ondřej (advisor)
Open Shortest Path First (OSPF) is a dynamic, hierarchical routing protocol designed to support routing in TCP/IP networks. There is a deliberate need for large-scale simulation of OSPF protocol in order to understand its dynamics. Content of this bachelor's thesis is modeling and simulation of OSPF protocol in discrete event simulation system OMNeT++. The main focus is to give an insight of the architecture of the existing implementation in module OSPFRouting. The module OSPFRouting is also validated against OSPF implementation on the real routers. Next, the usage of OSPF simulation is demonstrated on the specific experiments.

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.

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.

Modelling Cisco Router in Simulation Tool OMNeT++
Sivák, Vladimír ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This bachelor's thesis describes simulation of computer networks using open source simulator OMNeT++ including the INET Framework extension. According to real behaviour of Cisco routers, we implemented a new modul for the INET Framework extension. Casy study compares behaviour of real network with simulation of the same network in OMNeT++ using the implemented modul.

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.

Modelling of OSPFv3 Link-State Routing Protocol
Mrázek, Jakub ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
OMNeT++ is a discrete event, modular simulator often used for simulation of computer networks. The universal simulator can be extended by various packages, such as INET framework, which is used for simulation of devices and TCP/IP protocols. This thesis examines facilities of INET package in the routing that is dynamic routing protocols. Concretely, it aims at OSPF protocol for IPv6 networks (OSPFv3). The protocol is presented and its principles are interpreted. The work is designed to simulate the module OSPFv3 protocol and module is partially implemented.

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.

Modelling QoS in Computer Networks
Danko, Martin ; Veselý, Vladimír (referee) ; Ryšavý, Ondřej (advisor)
Quality of service (QoS) is an important consideration in networking, but it is also a significant challenge. Providing QoS guarantees becomes even more challenging when you add the complexities to the network like voice and video applications. This master's thesis focuses on QoS modeling and simulation in discrete event simulation system OMNeT++. The implementation of multiple techniques for QoS simulation is added to OMNeT++ within this work. All implemented modules are validated against the QoS tools on real routers. The last part of the work presents the possibility of QoS simulation in newly implemented modules.

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.

Using OMNeT++ simulator in teaching telecommunication technologies
Jalůvka, Jiří ; Zeman, Václav (referee) ; Novotný, Vít (advisor)
Main goal of this thesis is to familiarize with possibilities in simulating environment OMNeT++ with use of pre-integrated models or models imported from INET Framework. Simulated LAN networks created by 802.3 standard (ethernet) and 802.11 (Wi-Fi) will be performed in this simulation environment. In such networks, data traffic will be created at the application layer (video streaming, telnet, etc.) using the TCP and UDP transport protocol. For the UDP transport protocol graph will show a delay between end-to-end network elements in the first and second example and a jitter grap in the second practical example. For the TCP transport protocol will be performed „three-way handshake process“. Also, multi-way signal spread is shown by 802.11 standard.
