Creating a simulation model of the access network
Formánek, Juraj ; Slavíček, Karel (oponent) ; Grenar, David (vedoucí práce)
Thesis deals with generating and monitoring traffic in the GNS 3 simulation tool. The properties of the GNS 3 simulator are defined, including its capabilities for simulating/emulating components. Emphasis is placed on using only open-source tools. After analyzing the capabilities of GNS 3, a suitable traffic generator is found, which is preceded by practical testing of multiple generators. After finding the generator, monitoring tools are practically tested, with Zabbix emerging as the best from the tests. It was linked with the visualization tool Grafana through Zabbix plugin. Part of the work consists of automation, managed by Zabbix along with bash/Python scripts. The thesis evaluates the use of GNS 3 and explores its capabilities, possibilities, and limitations in the area of traffic monitoring and generation. The result is the creation of an access network with one router and two containers that generate and send traffic through this router. Everything is monitored by Zabbix and useful results are displayed in Grafana.

Evaluation of MPLS approach as a WAN technology for data transmissions in critical information infrastructure
Formánek, Juraj ; Blažek, Petr (oponent) ; Fujdiak, Radek (vedoucí práce)
Thesis deals by using MPLS technology in energy critical information infrastructure and its comparison with another modern approach in the area of the WAN management. For this purpose was chosen a Software-defined Wide Area Network technology. This thesis contains theoretical description and practical tests of particular MPLS technologies on the WAN topology, which is considered as a virtual real topology of the EG.D’s company. Test were simulated in GNS3 emulator, using Cisco routers. Practical test were firstly focused on availability test when link or node failure occurs and secondly on route- reflector failures. Conclusion sums up appropriate approach for data transmissions in critical information infrastructure based on informations or practical test in this thesis.
