Building and use of small computer networks
Böck, Adam ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This bachelor thesis deals with small local area networks which are used mainly at households. The work is divided into four main parts. The first describes the theoretical part of the networks, contains types of topologies, network models and the description of network devices. It also deals with both copper and wireless networks. The second part is focused on introducing the current status of my home network, which is extended in the third part of this work. The extension includes adding the server and providing network services. There is shortly described the setting of the services and the verification of the functionality in practice as well. The last part of this bachelor thesis is devoted to the project of the small business network using the latest available devices.

Building and use of small computer networks
Šrámek, Jan ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This paper deals with small local area networks. It describes types of network topologies. The paper also deals with network models and gives a brief review of basic protocols. Next part discusses Ethernet metallic network types and also wireless networks. Mentioning wireless networks it focuses on standards of signal transmission and instruments providing their security. Last theoretical part is devoted to active parts of local area networks. In the practical part of this paper are described instruments for building a home local area network and also suggestions for their improvement. This paper also deals with a small local area network with ten stations designed for enterprise usage. It also examines about choosing appropriate server for both environments. Last topic is building own home local area network. This network provides Internet connection and ensures network security through network server. Linux distributions are being briefly discussed, concretely distribution Ubuntu, which is installed on the network server. Work goes through basic configuration of the server, which provides basic functionality of local metallic and wireless network. In this part, link aggregation is being described. Server configuration also uses RAID technology. Some services are being provided by the server in the network, such as DHCP, FTP, Samba, basic configuration of these services is also included in this paper.

Network protocols and sockets
BALEJ, Marek
My work will deal with network protocols and sockets and their use in programming language C#. It will therefore deal programming network applications on the platform .NET from Microsoft and instruments, which C# provides to us. There will describe the tools and methods for programming network applications, and shows a description and sample applications that work with sockets and application protocols.

Design of computer network training room
KRHÁNEK, Jiří
This project describe design of computer classroom for learning computer networking. At first I explain how create computer network. I decide about hardware and network items to use for realization fully functional computer network. Below I describe network setting in Operating Systems. At the end I fixate to solution particular cases which could be resolved by students in this computer classroom.

Network status visualization
Hejna, Martin ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
The purpose of this diploma thesis is to provide a complex overview for the network status visualization topic. The diploma thesis is structured into four parts. The first one is dedicated to the definition of the most important terms, together with the description of several visualization methods, network metrics and last but not least to the discussion of visualization risks and benefits. In the second part, an own visualization process is at first proposed and then the particular steps of this process are discussed. Easy to understand examples are applied through this part. In the third part, several method of data collection protocols and visualization tools are briefly described. The analyzed tools are graphic libraries, as well as standalone applications and Network Management Systems. The last part is dedicated to the analysis of the current visualization tools used on the VŠE network. A short analysis of the university's network is also made. According to this analysis, an own solution is proposed for a particular part of network.

Network solutions with principles of systems thinking
Veselý, Luděk ; Mildeová, Stanislava (advisor) ; Exnarová, Anna (referee)
The main goal of this work is the application of system thinking in computer networks design and use of the systems thinking as a unique way of thinking and the presentation of the big potential which the systems thinking has in complex problem solving. Advanced network technologies are also described with their benefits for any organization. This thesis brings a whole new sight at the computer networks as a complex system and describes procedure of making a computer project in detail which can be used as a general reference model in the field of computer technologies. Solution include strong accent on how the basic knowledge of computer networking is important for information manager profession.

Support for Incident and Problem Management on Computer Network at University of Economics
Bank, Michal ; Pavlíček, Luboš (advisor) ; Matuška, Miroslav (referee)
This diploma thesis is focused on incident and problem management on computer network at University of Economics, Prague. Its goal is to study available models used in network management, analyze current status of network management support tools used at University of Economics and design and implement an application for effective diagnosis of network incidents based on this analysis. Information about network management models will be acquired from available sources -- primarily ITIL v3 and also online information published on the Web. The final part of this thesis is a fully functional web-based application which will be used by helpdesk operators to support them in finding event information in historical log files. This application will then be deployed on servers in University of Economics, Prague.

Zabezpečení přístupu koncových stanic
Beneš, Jiří ; Pavlíček, Luboš (advisor) ; Tlustý, Zdeněk (referee)
Diplomová práce se zabývá bezpečností koncové (pracovní) stanice v počítačové síti při použití pouze softwarových technologií. V první části je nejprve analyzováno zabezpečení pracovní stanice samotné, v druhé části zabezpečení komunikace pracovní stanice s počítacovou sítí a ve třetí části zabezpečení připojování oprávněných stanic a uživatelů do počítačové sítě. Pro každou oblast jsou zmíněny hrozby a způsob obrany za použití současných softwarových technologií. Teoretické poznatky jsou poté v případových studiích aplikovány na pracovní stanice v reálném prostředí.

Návrh počítačové sítě v nově postavené administrativní budově
Ptáčník, Tomáš ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
Cílem práce je popis, zhodnocení a následné porovnání procesu postupu návrhu nové lokální počítačové sítě dle doporučení firmy Cisco Systems (uvedených v základní literatuře) s postupem řešení dané problematiky ve společnosti Nestlé Česko. Shrnutí výsledků studie průběhu projektu přesunu místní počítačové sítě do nové budovy ve společnosti Nestlé Česko je uvedeno níže. Při této studii byl hlavním konzultantem tamější pracovník zodpovědný za dozor při návrhu a následně při stavbě počítačové sítě. Práce je přínosem pro tvůrce počítačových sítí v malých až středních podnicích (do 500 uživatelů) a pro managery takových projektů. Budou zmíněny důležité aspekty, možné postupy, principy a některé problémy při návrhu a okrajově i při provozu počítačové sítě.
