Application of simulation model of access network
Szymeczek, Andrzej ; Sládok, Ondřej (referee) ; Grenar, David (advisor)
The topic of the diploma thesis is " Application of simulation model of access network". The aim of the thesis was to create a part of the access network in which were tested simulations for TCP and UDP traffic. The theoretical part of the thesis deals with general information about the GNS3 program and the possibilities which this program allows. The next part of the thesis describes the Mikrotik RouterOS program, which was used in the topology. The next section describes the types of routing in IP networks, as well as the types of packet delivery. The practical part deals with the creation of test topologies and verification of the performance of the simulation tool. Furthermore, the practical part deals with the programming of a network generator for TCP and UDP traffic in the network. The generator was created by using a Bash script and a combination of the dd and nc commands. At the end, the thesis describes the results of simulations in terms of transmission speed, network throughput, packet size distribution and in the case of TCP also bidirectional delay – RTT.

Internet television within next generation access networks
Szymeczek, Andrzej ; Sládok, Ondřej (referee) ; Grenar, David (advisor)
The topic of the bachelor thesis is „Internet Protocol Television at the Access Networks of the New Generation“. The aim of the project is to make the network where internet television service is functional and after then to test the facilities and specifications of this network. The theoretical part of the project is focused on the basic characteristics and specifications of the internet television service. Further in the project is description of the network protocols for multimedia data transfer in real time and way of the transmission through the network. The simulation is designed in the simulation program GNS3. The simulation contains functional model of the network and because of the simulation is possible to run video streaming through the network. The transvered data and sideeffects, which have an influence on the function and quality of the stream, are analysed. Also the differences between unicast and multicast streaming are considered.
