Ethernet OAM for access networks diversity control
Varhola, Oliver ; Grenar, David (referee) ; Slavíček, Karel (advisor)
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.

Design of secure customer data center infrastructure
Linduška, Jan ; Svoboda Vlastimil, Ing., MBA (referee) ; Sedlák, Petr (advisor)
The bachelor thesis focuses on the design of secure customer data center infrastructure. The thesis is divided into four main parts and starts by defining the problems and identifying the objectives. The second chapter deals with the theoretical part discussing the basic technologies and principles on which the infrastructure design is based. The third chapter analyses the current state of the facility and gives the requirements. In the fourth and final chapter, a new design is presented, based on the previous chapters, which is then compared in an economic evaluation. The thesis concludes with a summary of the resulting design, which will serve as documentation, template and input for the contractor selection process.
