Laboratory exercises explaining network technologies using various simulation instruments
Vaľuš, Dávid ; Ilgner, Petr (referee) ; Bečková, Zuzana (advisor)
This diploma thesis focuses on the preparation of an operating system, a simulation environment and the creation of two laboratory exercises explaining network technologies. In the theoretical part protocols DHCP, FTP, TFTP, HTTP, and NAT service are described. The practical part focuses on the installation of ns-3 and GNS3 programmes and their utilization and settings on OS Ubuntu 18.10. Moreover, it deals with the preparation of laboratory exercises created in the simulation programmes mentioned above together with tutorials, self-check questions and HTTP server in the Python programming language.

MPLS based virtual private networks
Daněk, Michal ; Červenák, Rastislav (referee) ; Novotný, Vít (advisor)
Master thesis deals with architecture of network based on multiprotocol label switching technology (MPLS). Work also describes use of this technology for point to point or multipoint connections based on network or data link layer. The practical part is focused on design of laboratory task which is aimed to configuration of virtual private LAN service (VPLS). This technology emulates multipoint connection based on the data link layer.

Active security equipment in computer networks
Škrdla, Vojtěch ; Martinásek, Zdeněk (referee) ; Malina, Lukáš (advisor)
The main object of this bachelor's thesis is to describe problematics of active security devices. The thesis is mainly focused on firewalls. Thesis is divided into several topics, in which we describe types of security devices, division of firewalls, description of their advantages and disadvantages, types of VPN. The practical part describes the security design of mid-sized computer network, description of software that was used to test this network and the last part focuses on designing laboratory tasks with firewalls Cisco ASA5520 and Checkpoint Gaia R77.

Design of new laboratory exercises for GNS3 network simulator
Bureš, František ; Červenka, Vladimír (referee) ; Jeřábek, Jan (advisor)
The goal was to create three laboratory tasks with process and help in GNS3 environment. All laboratory tasks should be used for extending practise experiences from Cisco course CCNP and illustration of GNS3 function. Whole thesis is focused on using IPv6 and coexistence with IPv4. Teoretical parts are dedicated for preparation on laboratory tasks and their main goal is explaining and use of commands in specific problematics. In GNS3 environment, there is explained instalation and basic settings. Laboratory tasks on theme MP-BGP, IPv6 tunnels and IPsec VPN with use of VTI are divided into specific parts. The parts consist of the described procedures with topology, detailed instructions and the entire configuration in Annex.

Routing among autonomous systems in Internet
Daněk, Michal ; Komosný, Dan (referee) ; Novotný, Vít (advisor)
Bachelor thesis describes the architecture of the Internet, its division into autonomous system and methods of their interconnection. Furthermore extensively describes routing mechanisms among autonomous system but also inside. More space is dedicated to routing protocols OSPF and BGP. At the end of the work is designed laboratory task for subject Network Architecture where this protocols are used.

Proposal of the secure network model
Kis, Matej ; Rosenberg, Martin (referee) ; Babnič, Patrik (advisor)
The goal of this work was to create a design of a secured network infrastructure with decribing different ways of securing at ISO/OSI layers. Create a list of protocols which can be used to achieve a secured network design. In the theoretical part of this work the attention was placed to analyze possible solutions, which can be appllied in a practical part of the work. The practical part involves a design of a network topology and simulation. The part of the simulation was device configuration and network security testing.

Protocols Analysis of CISCO Networks
Karlík, Martin ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
ABSTRACT Bc.Karlík, Martin Department of Telecommunications, Faculty of Electrical Engineering and Communication, Brno University of Technology. Analysis of CISCO networking protocols This semestral thesis is focused on CISCO networks and protocols like MPLS, BGP, Ipv4, Ipv6, Multicast – sprase / dense mode. The task was study of those protocols and design and implement lab excercise with one of those protocols by using free network simulator GNS3. In this excercise is used CISCO router 3745.

Design of new laboratory exercises for GNS3 environment
Barniak, Martin ; Koton, Jaroslav (referee) ; Jeřábek, Jan (advisor)
Diploma thesis deals with four laboratory tasks in simulation environment GNS3. Designed tasks are primarily focused on comparison of IPv4 and IPv6 protocols. In the first task the subject is concerned about OSPFv2 and OSPFv3 routing protocols. Next themes are transit techniques like NAT-PT and tunneling like GRE and 6to4. The second task is focused on configuration of routing protocols like EIGRP and EIGRPv6. Next sections are concerned about DHCP and ICMP protocols within IPv4 and IPv6 protocol suits. The third task is primarily focused on security relations of protocol suite IPv6. It contains OSPFv3 authentication, access lists and Cisco stateful IOS firewall. Content of the fourth task is protocol MPLS. First part of this task is concerned about basic configuration of this protocol and second part is focused on MPLS within IPv6 environment. All tasks contain test questions and individual part task.
