摘要

The network architecture has undergone great changes. For example, the network topology of autonomous system level tends to be flattened. In this paper, actual network topology map is constructed through actual network routing data, to study and analyze the network structure changes of the Internet recently and the dependence of the Internet on the core AS. In order to achieve the above goals, the experimental analysis framework and some related algorithms were designed. Experimental results show that the Internet architectures gradually become flattening, and the dependence of the Internet on core AS is gradually reduced but the importance of the core ASes is still indispensable. Most traffic between local ASes can be transited through the local infrastructure (such as IXP) rather than the upper ISPs. The observations may guide the design of inter-domain routing protocols and Internet exchange architectures to achieve higher performance and reliability.
