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.

Design of labs for Cisco academy courses
Oujezský, Václav ; Růčka, Lukáš (referee) ; Jeřábek, Jan (advisor)
This master's work deals with the design of laboratory exercises for Cisco Academy courses. Especially is oriented on Cisco technology. The theoretical part describes various devices used in the laboratory and the issue of functionality of these devices, such as switching, routing and solve any problems with the configurations of these elements. The practical part is directly generated designs laboratory exercises, focusing on specific examples of the problems from the configuration and network management with Cisco. An integral part of work consists of supporting the presentation of individual laboratory tasks, including configuration files, settings of the device. Create labs and verify the functionality of their configuration has been realized in the laboratory Cisco Academy Brno.

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 protocols analysis
Rozsypal, Ondřej ; Langhammer, Lukáš (referee) ; Kubánková, Anna (advisor)
This bachelor thesis deals with the routing problematics and the routing protocols of the third layer of the ISO/OSI reference model. In the first part of this thesis basic principles of routing are described. The next part explains the differences in routing and the behavior of each internal routing protocol. The last part is dedicated to design of a network used for analysis of each protocol, collection of routing parameters in different conditions between the routers. These parameters are then plotted into graphs and diagrams. Based on this data an analysis of these protocols is made.

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.

Modelling of network communication in OPNET IT Guru environment
Mazák, Andrej ; Škorpil, Vladislav (referee) ; Hošek, Jiří (advisor)
The aim of this work is to describe modeling of network communication with the given network performance and load. The selected model of network approaches the real network topology of a telecommunication operator that provides network services for the customers. We take a closer look on the functions of the significant network protocols EIGRP and BGP and we also will focus on their configuration on the selected network devices. Routing in the network will be analyzed in the individual project scenarios with a use of selected routing protocols. Routing policy will be enforced for a BGP protocol in a separate scenario with an aim to prefer a concrete routing path to the destination, which is a common case of traffic engineering. The issue of virtual private networks is also taken into a consideration in an individual scenario, where there is Firewall as a specific network device used for separation of networks of a different trustworthiness and a following introduction of IP tunneling for an encrypted communication among the selected network entities within the topology. Simulation of the network communication is aimed on the response of FTP service, time delay of Ethernet, throughput of backbone links and communication flow in the targeted scenarios. The output of this work deals with the analysis of the achieved results, comparison of graphs as well as evaluation of the determined simulation parameters.

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.

Modeling and Simulation of EIGRP and BGP
Zavřel, Jan ; Marek, Marcel (referee) ; Veselý, Vladimír (advisor)
Internet se za posledních několik desítek let stal jedním z nejdůležitějších nástrojů pro mezilidskou komunikaci. Miliardy lidí ho denně používají na zábavu, na práci, na vzdělání či uspokojení lidského kontaktu. Je nutné si připustit, že na jeho správném fungování je obrovská část populace existenčně závislá. Toto se odráží na stále se zvětšujících požadavcích na vyšší rychlost, nižší zpoždění a větší pokrytí a stabilitu. Síťoví inženýři a architekti musí při návrhu a nasazení dbát právě na tyto aspekty. Jedním ze způsobů, kterým je možné navržené topologie otestovat, je simulace. Simulace využívá simulační modely, které, pokud přesně odráží realitu, mohou poskytnout klíčové informace o topologiích v bezpečném prostředí a to za velice přívětivou cenu. Tato práce se zabývá analýzou a následným vylepšením dvou simulačních modelů dynamických směrovacích protokolů EIGRP a BGP. Tyto modely mohou být použity k vytvoření komplexních simulačních topologií a scénářů v diskrétním simulátoru OMNeT++.
