Abstract

Alias resolution, mapping IP addresses to routers, is a critical step in obtaining a network topology. The latest work on alias resolution is based on special fields in the packet, such as IP ID, port number, etc. However, for security reasons, most network devices block packets for setting options, and some related fields exist only in IPv4, so these methods cannot be used for alias resolution of IPv6. In order to solve the above problems, we propose an alias analysis method based on delay sequence analysis. In this article, we present a new model to describe the distribution of Internet delays and give a mathematical proof. After experimental measurements using the Macroscopic Internet Topology Data Kit (ITDK) and Ark IPv6 Topology Dataset, it was found that the statistical differences in most alias delay models were very small. The statistical differences in the non-alias delay models are spread over a wide range. Using the wavelet decomposition in delay sequence, it was found that the approximate components and the detail components of the delay sequence of aliases were the same after filtering out the noise, which provided a theoretical explanation for the experimental results. This technology is applicable to both IPv4 and IPv6.
