The Internet contains more than 50.000 ISP’s (Internet Service Providers) so it’s very complex and difficult to understand its operation. It’s architecture consists of hundreds of thousands of autonomous systems and millions of BGP (Border Gateway Protocol) routers. The goal of my Thesis was to demonstrate the routers cooperation within the confines of a scheduler educational laboratory. With the help of the measurement configuration it is easier to understand how the system works. During the laboratory the university students had to configure different types of protocols to finish the project that gives an insight into the complexity of global network. The BGP’s set of rules is varied, can be customized and updated based on economical and social interest. I pointed out the differences between Hot Potato and Cold Potato routing, whereby the autonomous systems can customize their relations with their neighbours. It is also demonstrated how the Route Reflector helps to reduce the number of connections in an autonomous system. The last chapter contains the required commands and an exercise solution guide.
