Packet Classification Algorithms

V úvodu této bakalářské práce je rozebrána problematika filtrování provozu v síti a podstata klasifikace paketů. Dále se zabývá studiem vlastností několika základních klasifikačních algoritmů. Ve druhé části je detailně představen algoritmus Distributed Crossproducting of Field Labels. V závěru práce je popsán způsob implementace v jazyce Python a vyhodnocení činnosti programu v závislosti na různých množinách vstupních filtračních pravidel.In the beginning of this bachelor's thesis, the packet filtering and a base of the packet classification are discussed. It studies several basic classification algorithms. In the second half of this work, the Distributed Crossproducting of Field Labels algorithm is shown in detail. Finally, the software implementation in Python is described and the evaluation containing the memory dependence on various rule sets is presented.

Development of a location-based service for a Brno City District

There are many different types of places in any city. These places include playgrounds, dog runs, cultural heritage sites and many more. A city usually wants to provide information about location and equipment of these places. The common way is via a city website. However, nowadays a much more common source of information are mobile applications. This article deals with a development of a mobile application for the Brno-North district of Brno city. The application is designed to inform the citizens of the city district about interesting places in their vicinity. The central element of the application is a map which shows where all the interesting places are located. The application is focused primarily on families; however, it can be useful for any citizen of the district.O

Effective Collaborative Mapping Based on Mobile Devices

There are numerous situations when it is utmost important to share efficiently some spatial data among a group of people. Floods can be taken as an obvious example. Many stakeholders including mayor or rescue service workers must have actual information about the conditions in the terrain. And most importantly, all of these can contribute to the information. Among these situations involving the crisis management, we dare to mention especially the inventory process. Traffic signs, road lanes, trees, lights and many other different object must be regularly maintained. Most of the organizations use some kind of geographical information system to keep the information about the maintained property. Our article is focused on development of mobile application that allows to acquire spatial data that are later used in these information systems. Thanks to real-time data synchronization between multiple devices, field workers can cooperate and share data immediately to an operating center or with the other workers. We describe the design of our mobile mapping application, comparison with other existing solutions and problems of real-time synchronization between different devices. Finally, we provide details about application usage in different municipalities
