The objective of this Bachelor's Thesis was to explore Intel IXP1200 network processor, which is the best-known network processor at the moment. Its internal design and programming principles were to be examined. Digital Video Broadcasting was the other research subject from the network processor point of view. Example projects were used with the IXP12EB Ethernet Evaluation Kit, which is anexample system with 10/100 Mbps and gigabit Ethernet ports, implemented on top of Intel IXP1200 network processor. The study shows how to use the evaluation system. In this study, the requirements for transmitting the MPEG-2 transport stream were found to be excessive for IXP1200. The processor was still seen suitable for different implementations that contain dynamic properties, like Quality of Service and firewalling systems.
