Discrete Simulation of Programmable Systems
Mynář, Pavel ; Zuzaňák, Jiří (referee) ; Mlích, Jozef (advisor)
The subject of this thesis is the design and implementation of software library for discrete simulation of programmable units and their mutual communication and implementation of several illustrative examples based on it. The library is designed to be platform independent and as robust and simple to use as possible.

OMNeT++ Extension with ACL Filtering Module
Suchomel, Tomáš ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This bachelor's thesis describes discrete simulation of network in OMNeT++. We are exploring effective representation and evaluation of ACL rules by advanced data structures based on interval decision diagrams. OMNeT++ is extended by filtering properties of packets using access control lists. Because ACL filtering is not supported in OMNeT++, it was added as a brand-new module, whose concept and implementation is described here. Practical usage of the implemented module is demonstrated on a simulation of real nontrivial network. We also analyse results of the simulation and verify them by comparison with real network behaviour.

Simulation of Network Behaviour Based on Analysis of Configuration of Active Network Devices
Macků, Jiří ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This masters thesis describes simulation of network using Network Simulator. Model of network and description of simulation is extracted from the analysis of configuration files of active network devices, and translated by a parser. Concept and implementation of the parser is described here. Because IPv4 addressing is not supported in Network Simulator, it was added as a new module. The Network Simulator is also extended by filtering properties of packets using access control lists. Practical usage of the implemented modules is demonstrated on a simulation of real network.

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 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.

Using of Discrete Event Simulation in a Production Planning
Shylin, Ivan ; Chadima, Libor (referee) ; Videcká, Zdeňka (advisor)
Diploma thesis is dealing with the possibility of use of discrete event simulations in a production planning. The connection of the work measurement and the production planning is described. The thesis describes the modeling methodology, design and realization of the experiment with the model. The production planning part describes the processing of the data generated from the model, which are further used to demonstrate the planning method and optimization of the production plan.

City Traffic Simulator
Dostál, Martin ; Dalecký, Štěpán (referee) ; Rozman, Jaroslav (advisor)
This thesis is focused on microsimulation of city traffic, specifically a small city circuit in Brno. The thesis describes approaches for solving the problem of road network representation and presents basic methods and models needed for traffic simulation on the level of individual vehicles control as well as on the level of simulator control. In the case of more possible solutions to the given problem, the features and suitability of these solutions are compared. In the practical part of the thesis, the structure of the proposed simulator is presented with all the dependencies among individual submodels, along with the description of implementation details related to the individual parts.

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.
