The master thesis „IP traffic performance“ is focused on traffic testing in IP networks. Theoretical section explains routing issue in an autonomous system. This work contains a detailed description of OSPF protocol. This work also deals with behavior of a link failure. There are described mechanisms that are used to link failure detection and subsequent traffic rerouting. The next section describes mechanisms to ensure quality of service. In master thesis are explained InterServ and DiffServ mechanisms. A large part is devoted to DiffServ mechanism that ensures distinction of data flows and classification packets into different classes. The routers than can process the individual data streams with different priorities. The practical section includes the design of experimental network and creation of simulation in Opnet Modeler. By using several scenarios are compared the characteristics of routing protocols and impact of QoS on the transmission characteristics of the network. Part of practical section is the improvement of OSPF protocol by adding a new metric and implementing a new metric in software suite Quagga.

Controling in the Management of Business Informatics (MBI)
Grombíř, Jakub ; Pour, Jan (advisor) ; Pražský, Petr (referee)
The diploma thesis is focused on creation of a controlling model, which follows the structure of a reference model for management of business informatics MBI. The model is being developed under the grant project at the Department of Information Technologies, at the University of Economics in Prague and cooperation with Czech Technical University in Prague. The theoretical part provides a brief introduction with the MBI model and the area of controlling. The practical part contains three main objectives. The first objective focuses on creating fundamental controlling objects in the MBI model. The second objective is to design metrics and dimensions, which provides the possibility to measure and view controlling from a different perspective. The third objective deals with the creation of an analytical application, which is used for tracking costs, expenses and effects of the controlling in company. The main contribution of this work is the created controlling model in the information basis MBI. Created objects serve companies as a starting points for implementation and operation of controlling. The model also enables watching and analyzing contributions and costs of controlling. Newly created objects are designed in a way that companies can use just some of them without the need of deployment the whole model.

Application of dashboards in the area of support of IT management
Sakař, Václav ; Pour, Jan (advisor) ; Šedivá, Zuzana (referee)
This diploma thesis is focused on the issue of IT management in the companies, which is described in the MBI (Management of Business Informatics) model, at all levels of IT management in the way how they are defined and used by MBI. The main goal of this diploma thesis is design and create (new/modified) content in the area of IT management in the MBI model for broader usage of this model in the company sphere. The main goal is fulfilled by fulfilling of two sub-goals. Firstly, it is designing and creating new metrics, dimensions and applications or modification (extension) of already existing content in MBI model. Secondly, it is implementation of new or (selected) modified content with Microsoft PowerPivot into the form of interactive applications and then into the dashboards composed from them. The structure of this diploma thesis is adjusted to make those sub-goals achievable. The structure is divided into theoretical and practical section containing together six main parts. Firstly, the two most widely used methodologies of IT management and mainly MBI model are described. Then the definitions of metric (as a main instrument, which is used in IT management) and its attributes are described. Following section contains definition of dashboards and basic description about their designing and creating. In the last part of the theoretical section are described metrics, dimensions, applications and their connections in the MBI model. First part of practical section is about designing and creating of new metrics, dimensions and applications or modifying of already existing content. The last part of this thesis contains implementation of a new or (selected) modified content into applications or dashboards. Main benefit of this diploma thesis is enrichment of existing content in the MBI model in IT management (specifically in the metrics, the dimensions, the applications and the dashboards based on those three things), which improved usability of the MBI in practical usage. Thanks to this extended content, the users or mainly the management employees can react in better way on the potential problems, have better overview about level of quality of the IT resources, can manage the employees in better way and can coordinate quality and quantity of the IT outputs in better way in general.

Gottwald, Karel ; Novotný, Ota (advisor) ; Maryška, Miloš (referee)
Diploma thesis focuses on topic of business performance management realized through Business Intelligence application created on the basis of a balanced set of indicators within the Balanced Scorecard method. The first part introduces the reader with theoretical foundations. First, it describes the basic principles of the BSC method and meaning of dividing strategic objectives into four perspectives. Subsequently, it introduces the heart of BI - a multidimensional approach, displays the BI architecture and defines its components. At the end it compares the types of database systems. There is also a comparison of this thesis with other projects dealing with similar themes in the theoretical part. After the theoretical chapters comes a practical part which aims at design and development of BI applications for a real company so as to comply with the requirements of top managers and the corporate strategy. At the beginning it introduces a firm to which the project is applied. This is an existing organization operating in the area of car sales and services. The corporation is called under a fictitious name "AUTO a.s." in this thesis. In cooperation with its managers the SWOT analysis and strategic objectives is defined. This determines the key requirements for setting up the BI application. An example of a BI solution that allows managers to effectively monitor the development objectives, brings the main benefit of the whole work. For this purpose is built data warehouse, which is then filled with transformed data from source systems using Data Pump. Then, above the Data Warehouse, two OLAP cubes can be created. Presentation layer, created in MS Excel 2007, handles the interpretation of the results to end-users.
