Měření a monitorování výkonnostních parametrů sítí nové generace
Grenar, David ; Vlček, Čestmír (oponent) ; Róka,, Rastislav (oponent) ; Smékal, Zdeněk (vedoucí práce)
Práce se věnuje tématu přístupových sítí nové generace. V práci je nejprve proveden rozbor současného stavu poznání zaměřený na aktuální technický ale i legislativní vývoj a trend v přístupových sítích. Práce popisuje aktuální strukturu přístupových sítí a analyzuje stávající stav problematiky přístupových technologií. Dále jsou uvedeny měřící a testovací metody pro jejich ověřování v závislosti na typu sítě či provozu IP služeb. Poté disertační práce představuje matematické metody, které lze využít pro vyhodnocovací model přístupové sítě. Následně jsou vyhodnocena doporučení a metody pro monitorování a modelování dat z přístupové sítě. Předmětem zájmu je zde zejména problematika intenzity provozu. Práce předkládá návrh pro konstrukci matematického modelování provozního profilu a jeho využití.

Ethernet OAM for access networks diversity control
Varhola, Oliver ; Grenar, David (oponent) ; Slavíček, Karel (vedoucí práce)
The Bachelor's thesis describes Ethernet access networks and the specifics of the telecommunication Ethernet Service with a focus on Diversity access. Ethernet OAM (Operation, Administration and Management) link layer protocols IEEE 802.1ag and 802.3ah are described, implemented and tested. Suggested use of OAM for verification of Diversity Single Point of Failure (SPOF) trial is conducted by utilizing Link Trace Message / Link Trace Response (LTM/LTR). Simulation using GNS3 emulator is performed in order to capture Link Layer (L2) traceroute to neighboring MIPs and MEPs (Maintenance Intermediate Points and Maintenance End Points). The resulting traceroute path containing MAC addresses of the ports through which the frame was sent is recorded, analyzed and compared with a sibling diverse circuit. If MAC addresses are equal or from a close range it indicates that the circuits may pass through the same device and thus a potential SPOF is detected.

Utilization of open source tools for access network monitoring
Gmitter, Jakub ; Sládok, Ondřej (oponent) ; Grenar, David (vedoucí práce)
The bachelor thesis deals with the issue of access network monitoring, which is necessary to ensure the stability of access networks. It contains a comparison of suitable monitoring tools for their selection. The work is focused on creating scripts in the Bash language, which analyze data on the access network and implement outputs from selected monitoring tools. In this work were analyzed the transmitted packets and the achieved transmission speeds during monitoring. The final output of this work are databases created in MySQL, which contains data about the analyzed parameters and visualization of data analysis using the Grafana program. Graphs of the transmission speeds of monitoring and basic transmission statistics were created on panels during visualization.
