My thesis is mainly focused on layer 2 networks, switching and their performance. My research consists of 2 parts; theoretically and practically. In theoretical part, I wrote about L1/L2 switching technologies, network simulation and tools, AI implementation on network simulation. In practical part, I created several SDN topologies in Mininet and conducted several test. With help of intelligence of SDN controllers, I extracted data from network and performed several analysis by auto-generated charts.
