An Experimental Study on the Core Autonomous System of Internet

With the continuous development of the Internet, the structure of the network has also undergone great changes. The Internet is gradually flattening, and the links between autonomous systems are increasing. Many autonomous systems realize direct transmission through Internet switching centers or related links. In order to analyze the transmission changes of the core autonomous system in the Internet. Based on the historical data of actual network routing information, this paper studies and analyzes the development of the Internet and the transmission changes of core autonomous system in the Internet. For further research and analysis, this paper designs the experimental model and related algorithms, constructs the Internet topology relationship according to the actual network routing data, and carries out independent experiments on the core autonomous system. According to the experimental results, we can find that the hierarchical structure of the Internet gradually blurred, AS the core formed dense links between local network and can provide affordable for the Internet, while the core AS the transfer function of the Internet in weakening, but the core AS the stability of the transmission of the Internet is still very important, and even play a crucial role.
