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.

Measurement of Backbone Routing Parameters
Celárek, Ondřej ; Kořenek, Jan (referee) ; Matoušek, Jiří (advisor)
This thesis deals with issue of routing between Autonomous Systems. For routing between autonomous systems is used Border Gateway Protocol (BGP). The routers in Autonomous Systems modify their routing tables based on BGP messages. Routing tables are used for forwarding information on Internet. Issue of this thesis is analysis of change routing tables for eventually optimizing of routing architecture. First part of thesis is focused on theory of routers, routing ang BGP. Second part of this thesis focuses on implementation and execution experiments with routing tables. In this part are also described reached results.

IPv6 Communication Library
Pecháček, Václav ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
Thesis deals with IPv6-based network communication. The aim was to create a library enabling FITkit development board equipped with Ethernet extension module to act as an IPv6 node. Project includes application to demonstrate available functionality. The library is written in ANSI C.

Longest Prefix Match Search
Chrastina, Ondřej ; Puš, Viktor (referee) ; Tobola, Jiří (advisor)
This thesis deals with the problem of an efective routing and a data clasification in computer networks, in particular searching for the longest prefix match for the internet protocol of version 6. First the algorithm, Binary Trie, Level Compressed Trie, Lulea Compressed Trie and Binary Search on Intervals, are described and then tested to find the the most suitable algorithm from the viewpoint of memory requirements and the speed of the searching.

Graphical Tool for IPv6 Packet Generation
Jochec, Jakub ; Bartoš, Václav (referee) ; Puš, Viktor (advisor)
This thesis is targeted on creation of graphic interface for generating IPv6 packets which can be used for creation of correct packets with different options. It describes TCP/IP model of network and IPv6 including extension headers. In next part is presented some of existing tools for IPv6 packet generating. Last part includes user interface design and implementation using Python and wxPython and Scapy libraries.

IPv6 Network Address Translation
Rek, Vít ; Polčák, Libor (referee) ; Grégr, Matěj (advisor)
This thesis deals with the translation of network addresses in the Internet protocol version 6. The aim is to use translation in the automatic configuration of end devices. In this work are discussed existing mechanisms for the dynamic configuration, and their advantages and disadvantages. There is designed and implemented system for connecting home computer network to the Internet, which combines Network Prefix Translation and Neighbor Discovery Proxy technologies.

IPv6 Hosts Monitoring
Rapavý, Martin ; Kašpárek, Tomáš (referee) ; Lampa, Petr (advisor)
This thesis is dedicated to network layer protocol IPv6, purposes of its creation and penetration. Former chapters briefly describe IPv6 protocol format and protocols, methods and technologies related to IPv6. The thesis summarizes security risks and flaws in IPv6 and ICMPv6 protocols. In context of the risks and flaws the thesis describes several of local ICMP attacks. It also mentions security incidents resulting from exploiting those security flaws and means of countermeasures. One of the used countermeasures is passive monitoring of ICMP messages. Thesis contains brief description of tool used to achieve this - NDPMon with its advantages, disadvantages and concepts of usage. Rest of the thesis describes design and implementation of monitoring tool similar to NDPMon, but with some improvements.

Server for Automatic IPv6 Tunnel Connectivity
Drahoš, Vojtěch ; Grégr, Matěj (referee) ; Matoušek, Petr (advisor)
One of the major problems of modern Internet is the upcoming depletion of addressing space in IPv4 protocol. This master thesis focuses on the study of network protocol IPv6, the possibilities of expanding this protocol in the Internet using the appropriate tunelling method and ways of tunnel management, especially the TIC protocol. Major goal of this work is using knowledge of protocols in a design and implementation of the server part of tunnel broker system, which uses mentioned tunneling method and is compatible with the open source client AICCU. Second part of this work deals with testing and pilot deployment of this system. Main benefit consists in creation an open source tunel broker system. Real deployment of this system is particularly advantage for Czech users as a low latency tunnel IPv6 Internet.

Longest Prefix Match Algorithms
Weigner, Martin ; Puš, Viktor (referee) ; Tobola, Jiří (advisor)
The speed of computer network is increasing. One of the basic tasks which has to be solved by the network devices is longest prefix match. Many algorithms are able to solve this task but it's necessary to solve it very fast because of increasing transfer speed and the routing standard IPv6. This standard has longer addresses and it's necessary to search prefixes in much bigger sets. The thesis describes present algorithms that solve the problem. These are confronted with new algorithm HashTreeBitmap which is also described in the work. On the tests is documented that this algorithm is able to cope with high demands which are placed on it.

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.
