ISP Network Optimalization
Čech, Ondřej ; Podermański, Tomáš (referee) ; Grégr, Matěj (advisor)
Bachoelor's thesis is focusing on analysis of network local ISP, detecting actual problems and offering a solution for founded problems. There were problems with broadcast-storm, private address space, RSTP protocol settings and DHCP spoofing. The following changes were introduced: OSPF routing, RSTP override, automatic backup, client separation using DHCP. There has been a reduction in broadcast traffic and associated broadcast-storm.

New laboratory exercises in OMNeT++ simulation enviroment
Petrůj, Jakub ; Sládok, Ondřej (referee) ; Langhammer, Lukáš (advisor)
This Bachelor thesis illustrates a draft and creation of two lab exercises in a network simulation environment of OMNeT++ with INET Framework extension on behalf of Communication Technologie course. Initialy, simulated environment itself is defined and, including NED language and its modules, then the process of simulation and analysis of its results are presented and discused. Further more this work describes theoretical network knowledge required to create the simulation and treat its results. The first methodical part of this work compares HTTP, FTP, Telnet and VOIP protocols in simultaneous and non simultaneous running, with increased occurance of errors on line or its complete outage. The second methodical part of this work observes dynamic network configuration using DHCP protocol more in detail. Futhermore, this part studies the question of both non-efective and efective subnetting and handles issues concerning static adressing of network.
