This masters thesis is about mutlicast. There are explained 2nd and 3th layers of the ISO/OSI model multicast addressing. Routers in a network use multicast routing protocols to optimally route multicast packet through the network, this is also in this project. These multicast protocols are DVMRP, protocol PIM in his two modes, PIM Sparse Mode and PIM Dense Mode. Protocol DVMRP uses protocol IGMP, which is described as well. At practical section of this masters thesis is presented connections, by which tests was executed.

This diploma thesis deals with the design and implementation of a tool for network attack detection from a captured network communication. It utilises the tshark packet analyser, the meaning of which is to convert the input file with the captured communications to the PDML format. The objective of this conversion being, increasing the flexibility of input data processing. When designing the tool, emphasis has been placed on the ability to expand it to detect new network attacks and on integrating these additions with ease. For this reason, the thesis also includes the design of a complex declarative descriptions for network attacks in the YAML serialization format. This allows us to specify the key properties of the network attacks and the conditions for their detection. The resulting tool acts as an interpreter of proposed declarative descriptions allowing it to be expanded with new types of attacks.

The aim of my master’s thesis is a system for control of the light intensity. It is electronic equipment which controls the intensity of the light circuits based on settings and input signals. This equipment could work on single-phase systems or multiphase systems. The equipment is controlled by the signal DMX-512 which is a standard for the control of lighting technologies. The set up of this equipment is based on a personal computer or in a limited form by a small connected display.
