Implementation of network protocol into network simulator 2 environment
Janiga, Robin ; Mlýnek, Petr (referee) ; Koutný, Martin (advisor)
This thesis describes a protocol for the multiple data collection system and his implementation into Network Simulator 2 environment. The system defines two communication units. CU central unit and measuring unit MU. The units operate according to the rules defined by communication protocol. The content of this work is as follows. At the beginning is described the simulation tool, namely a system NS-2 and a tool for visualization of simulation results, the NAM. This is followed by a description of the proposed protocol, his principle of functions, units description and communication messages. The method of communication between units. Mainly was described the multicast and the types of multicast ASM and SSM. Additionally, was described the principle of unicast communication. This is followed by chapter describing methods of enlargement simulator. Adding an own protocol and support of multicast communication SSM. Adding a new protocol is represented by programming a new agent, a new application and a new protocol header definition. In this chapter are also described the necessary changes in the source files that are need to the recompilation. The main objective of this thesis is own implementation of the proposed protocol. In the programming language C++ were created two agents who represent a central and a measuring unit. These agents were compiled into a simulator and by using a simple script have been tested for functionality. The simulation script define MU 200 and one unit CU. Conclusion of work is devoted to simulation the load line between the central unit and "access" node. It was examined whether the use the method of cumulative acknowledgement saves the transmission capacity of line compared to normal method acknowledgement.

Implementation of IPv6 Protocol in Corporate Network
Priesnitz, Pavel ; Kovář, Vladislav (referee) ; Ondrák, Viktor (advisor)
The bachelor’s thesis focuses on the IPv6 internet protocol implementation in Teplárny Brno, a.s. network. At the first part it contains a brief definition of the protocol, differences between IPv6 and IPv4 and the teoretical description. Practical part is focused on the analysis of the network infrastructure present state in the real enviroment and offers some possible solution to implementation including recommended devices.

Streaming of 3D Geometry over Network
Rozehnal, Jaroslav ; Beran, Vítězslav (referee) ; Přibyl, Jaroslav (advisor)
This thesis is oriented on problematics of streaming 3D geometrics over network. Main importance is seen in efectivity of streaming, for what there is presented special protocol, working over protocol UDP, and adaptation of Level of Detail. For visualization of transmitted geometry trivial graphical engine is developed. In the end there are presented results of tests, oriented on protocol's efectivness.

Existing Attacks on SSL/TLS Protocol
Lysoněk, Milan ; Smrčka, Aleš (referee) ; Fiedor, Tomáš (advisor)
SSL/TLS is a modern cryptographic protocol, which secures the communication between client and server. However, there are attacks on this protocol which can compromise communication either by eavesdropping or disruption. Defending against such attacks and testing the bulletproofness of protocols is a challenging process. This work describes attacks on SSL/TLS and implements selected attacks within tlsfuzzer --- a sophisticated solution for testing SSL/TLS implementations. The resulting implementation of attacks is demonstrated on three SSL/TLS implementations.

Ethernet Interface Module on FITkit Platform
Šoustar, Jiří ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
This graduation thesis is aimed at design and implementation of embedded systems, network communication and support of the network communication for embedded systems. Furthermore it introduces school platform FITkit and offers a conceptional extension of the network interface for this platform based on Ethernet network standard. Based on that conception I'm trying to find and describe suitable solution for FITkit platform which realizes a network interface as a form of extension module capable of development supporting.

Use of TCP/IP Protocols for Algorithm Control in Real-Time Digital Audio Signal Processing
Pilch, Martin ; Plchot, Oldřich (referee) ; Černocký, Jan (advisor)
This thesis deals with design of protocol for control of digital audio signal processing over TCP/IP networks. The application of this protocol in embedded audio processing units allows to remote control of real-time processing of digital audio signals. The library, this thesis disserts on, allows for superior and faultless transfer of data and accordingly reliable control of audio signal processing at long distances via the local network or Internet. This library is designed to transfer any type of data and can be applied in any sphere.

Network Game: Destroy the Submarine
Kovačič, Dušan ; Herout, Adam (referee) ; Szőke, Igor (advisor)
The goal of this bachelor's thesis Network game: Destroy the submarine is to analyze and implement network architecture and solve all the problems connected with it. In final version, the created program uses client-server network architecture. Both subjects are communicating with complex network protocol. For effective data the virtual connection over UDP protocol is established. Minor part of this study solves graphical problems and received data displaying. For this purpose, there are different frequenc ies used for data handlings and techniques that provide better game experience.

Protokol pro sdílení souborů
Matějek, Jan ; Mareš, Martin (advisor) ; Falt, Zbyněk (referee)
Today's networked computing environments rely heavily on the ability to efficiently transfer data between computers. In order to understand the issues and challenges involved in sharing files and publishing directory trees over a computer network, we examined and summarized features of a number of popular protocols. Using this knowledge, we designed NewTP, a modern file sharing protocol suitable for the Internet. Special emphasis was placed on simplicity of implementation and resistance to attacks. We have proven the protocol's real-world viability by implementing a reference server and a FUSE filesystem module. Powered by TCPDF (www.tcpdf.org)
