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.
