This master thesis deals with self organized Mesh network. It describes routing and particular routing protocols, which are used in these networks. The thesis deals with Mesh network QoS assurance. Analysis and theoretical background of Mesh networks, routing and router protocols are included in the first chapter. Basic models of assuring Quality of Service are also described. Those are Best Effort, IntServ and DiffServ. Second chapter describes the devices used in the specific Mesh network topology - Trospos 5210 MetroMesh router produced by Motorola Canopy. Basic settings and properties required to establish a Mesh network are described. Next part of the thesis is the design implementation, which involves creation and configuration of the Mesh Network. Network configuration consisting of two Gateway points and afterwards behaviors of the network in a steady state versus one gate failure are compared. Furthermore, implementation of QoS according to components that support two types of QoS assurance regarding type of bandwidth reservation and defined traffic classes. In conclusion, the thesis describes measurement methods of QoS parameters for chosen applications, evaluation and comparison of measurement results for both types of Quality of Service assurance.

This master's work deals with the design of laboratory exercises for Cisco Academy courses. Especially is oriented on Cisco technology. The theoretical part describes various devices used in the laboratory and the issue of functionality of these devices, such as switching, routing and solve any problems with the configurations of these elements. The practical part is directly generated designs laboratory exercises, focusing on specific examples of the problems from the configuration and network management with Cisco. An integral part of work consists of supporting the presentation of individual laboratory tasks, including configuration files, settings of the device. Create labs and verify the functionality of their configuration has been realized in the laboratory Cisco Academy Brno.

This work deals with the qualitative requirements on services in IP networks based on technology Ethernet. We describe basic methods for imposing quality control mechanisms on services within networks. We elaborate on the ways, in which packets can be handled, overload controlled and transfer speed in network elements limited. Attention is given also to the Network Layer and Link Layer. Based on concrete specifications of network devices in UTKO laboratory an experimental network was designed and constructed. Network consisting of routers and switches linked several servers with client stations. Various types of data transfers (VoIP, HTTP, FTP, video) were generated. Several techniques for handling packets with different priorities were verified and compared. We observed that, in situations when connections are under full load, implementation of QoS support in the network becomes very important. This observation was confirmed by measurements. We also measured the parameters of the system during simulations of various situations, such as overload of a connection due to unsolicited operations or failure of a connection between routers. In order to guarantee the quality of services it is necessary to create a domain, in which rules are consistently observed in all network elements.

The goal was to get acquainted with the problems of network elements to describe neural networks that can be used to manage such a feature. The theoretical part deals with the neural networks from their inception to the present. It focuses mainly on the network, witch can be used for management control. These are the two network: Hopfield network and Kohonen network. The practical part deals with the network element model and ist implementation. It contains a practical element model using a neural network, witch is controlled by a network element.

The diploma thesis describes theory that is needed for application development for acquisition of communication statistical data from network infrastructure devices. Aplication is called SDSKSI. The project compares protocols suitable for this purpose. Finally SNMP protocol was chosen because it is the most common in network devices. SNMP is described in detail. Each SNMP operation has its own practical demonstration. In the project there is also described MIB database and data types of MIB objects. Application is able to create network topology. Then administrator of network can imagine how the network looks like. For each device that support SNMP protocol are periodically collected and stored statistical data which can be exported to the file. For application development were chosen programming languages according to several criteria. Content of the laboratory exercise is presented. At the end of the project there are some system solutions for collecting statistical data. Diploma thesis contents two attachments. The first is containing the full text of laboratory task. The second is DVD disc. Disc is containing ready to boot aplication SDSKSI.

This thesis deals with the routing of data traffic to multiple gateways with a network operating system MikroTik RouterOS, which has become widespread in the small firms and home users. It is aimed to describe the problem with using multiple gateways. RouterOS description itself and its core components needed to solve this issue, such as routing, packet marking and quality assuranceservices. It also deals with the description of the particular design and testing. The proposedsolution is verified on the example of a real situation. Finally, the proposed solution is compared to alternative solutions, commonly used in practice.

This thesis addresses the issues of network topology mapping, where the network consists of multiple Cisco devices. It includes theoretical knowledge in this field and closely describes possible solutions to this problem. It explains the process of design and implementation of this kind of network mapping software by chosen means. Correct function of the created application is tested on a virtual network.

This work deals with the public data network covering of the locality of the noth-east part of Brno and neighbouring villages.

The thesis concentrates on the network infrastructure problems , its proposal in the civil service area and analyses in detail the present condition of surroundings in the chosen organisation which requirements and needs for the suggested network infrastructure result from subsequently . On the base of the analysis it considers the posibility of realising the network infrastructure which consists in the choice of the suitable technology and the proposal of the computer network structure , including the implementation the solution in the given organisation and the specification of the financing resources.

This master thesis deals with the implementation of the RIPng routing protocol in the OMNeT++/INET environment. It describes the RIPng protocol and its specifics on the Cisco devices. It clarifies important concepts such as IPv6 and distance-vector routing protocols. The thesis also describes the OMNeT++ environment and the INET Framework, where it focuses on the current status of implementation of the components required for the RIPng protocol integration.
