Improvement proposal of particular services provided by STUDENT AGENCY p.l.c.
Podéšť, Jaroslav ; Sádlík, Libor (referee) ; Chalupský, Vladimír (advisor)
The subject of this bachelor’s thesis is to make improvement proposals of services related to a luxury bus transport based on a research on customer satisfaction. The theoretical part deals with services in general as well as their quality. It is followed by customer satisfaction, customer loyalty and possible relation between them. To obtain some primary data a field research at the busy bus station was carried out. Respondents were asked to express their overall and particular satisfaction. The findings are finally presented and discussed. It is believed that this study will help to understand the company passengers better.

Verification of stable next generation networks via transmission parameters measurement
Gregor, Lukáš ; Čučka, Milan (referee) ; Grenar, David (advisor)
This thesis deals with the measurement of transmission parameters in the new generation access networks NGA. The aim of the thesis is to build and configure a test network and scenarios for the measurement of service quality parameters and then verify the transmission stability. The theoretical part describes general functioning of NGN networks, the requirements of different telecommunications services on quality parameters, methodology and recommendations for measuring transmission parameters in packet networks. The practical part deals with the configuration of scenarios using mainly MPLS technology and methodology of their testing. Measurements were performed according to recommendations IETF RFC 2544, IETF RFC 6349 with the ExacTCP test and ITU-T Y.1564 with the EtherSAM test. For measurements were used measuring instruments of EXFO brand. In conclusion, the measurement results according to the mentioned standards were evaluated and also the advantages of using the measurement according to the given standard in NGA access networks were discussed.

Effect of Network Link Failure and Alternative Route Usage on Quality of Service Assurance
Atanasčev, Petr ; Škorpil, Vladislav (referee) ; Hošek, Jiří (advisor)
Information about the differentiated services (DiffServ), the link failure problems and the alternate routes in a DiffServ domain finding are the aims of the master´s thesis to be given. Properties of the differentiated services, the usage of marking techniques in the DiffServ domain are described in the thesis. The concept of the DiffServ domain, its structure and mostly used today routing protocol OSPF are described too. The function model of the DiffServ domain has been created in the simulation environment called Opnet Modeleler on the basis of the obtained knowledge. The link failure and the following link recovery have been simulated in the model and the effects have been analyzed after that.

Influence of Traffic Management Parameters Settings on Efficiency of DiffServ Technology
Ludvíček, Pavel ; Skořepa, Michal (referee) ; Hošek, Jiří (advisor)
Main purpose of this bachelor thesis is to understand concepts of Quality of Services system in IP networks with main focus on DiffServ technology and packet classification on boundary routers. DiffServ domain model will be created using OPNET Modeler simulation software. Various scenarios will be created to determine level of influence of individual parameters in DiffServ mechanism to selected network transfer characteristics. Particular mechanisms of packet management will be set as well as various types of queues used in DiffServ technology. Each setting will be tested using simulation in OPNET Modeler and compared using graphs.

Queuing Systems of Active Networks for Controlled Packet Sending
Vala, Ondřej ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
This bachelor thesis is describing queueing systems to provide quality of services in telecommunication networks. The work consists of a theoretical and practical part. The theoretical part describes the types of algorithms, which are used in active components and protective mechanisms against queues congestion. In the practical part, there is the analysis of the real Matlab-Simulink model. The last chapter of the practical part is devoted to the comparison of all the systems in terms of packet loss and packet delays in queues at constant input intensity of data streams.

Quality of Service Assurance introduction in Wireless Network
Branč, Martin ; Růčka, Lukáš (referee) ; Hošek, Jiří (advisor)
This bachelor´s thesis gives a complete overview of wireless networks 802.11.It describes the basic standards and their drafts. This thesis is divided into four chapters (sections), from which two are theoretical and two practical. The theoretical part contains a comprehensive overview of all standards, the history of wireless networks and technology. Further the support of quality of service in wireless networks is here analysed and in more detail standard 802.11e. In the practical part there is the network configuration described, at which the measurement was taken. The last part is already the implementation of support for quality of service, programme IxChariot measurement, evaluation of the results and differences between network traffic with and without support for quality of service.

Quality of Services in Wireless Networks 802.11
Kopeček, Tomáš ; Skořepa, Michal (referee) ; Vyoral, Josef (advisor)
This bachelor’s thesis reports an integrated view of wireless networks of standard 802.11, known as Wi-Fi. It contains three main parts, the first two of them are theoretical knowledge. The first part of work have to do with the security issue of WLAN, the second part refers to security issue of quality of services (QoS). The aim of the third, practical part is to verify the right functions of standard 802.11e, which ensures the support of quality of services in networks 802.11. Because of huge expansion of multimedia services demand, is this support in wireless networks necessary.
