Claim 4:
5. A cyberspace coordinate system creation apparatus based on an Autonomous System (AS), comprising a memory and a processor, the memory having a computer program stored therein, and the processor being configured to execute the computer program to perform a method, comprising:
determining a two-dimensional cyberspace coordinate system, by mapping, based on a predetermined algorithm, a one-dimensional AS Number (ASN) to a two-dimensional coordinate space;
constructing a framework for a three-dimensional cyberspace coordinate system, by orthogonalizing a time sequence of Internet Protocol (IP) address allocation under the AS determined as a third-dimension basic vector to a two-dimensional AS coordinate space, and analyzing and mapping an IP address of a key attribute of cyberspace;
constructing a cyberspace map model based on the cyberspace coordinate system and the framework for the three-dimensional cyberspace coordinate system; and
designing an application scenario corresponding to a constructed cyberspace map model, and visualizing the application scenario based on the constructed cyberspace map model,
wherein the framework for the three-dimensional cyberspace coordinate system is a three-dimensional coordinate system that comprises a third-dimension coordinate axis perpendicular to a basic vector of a two-dimensional AS;
said orthogonalizing the time sequence of the IP address allocation under the AS determined as the third-dimension basic vector to the two-dimensional AS coordinate space comprises:
representing the time sequence of the IP address allocation under the AS by a third coordinate axis perpendicular to the two-dimensional coordinate system, a positive direction representing sequence increment; and
said analyzing and mapping the IP address of the key attribute of cyberspace comprises:
modeling the cyberspace by defining a three-dimensional coordinate system space, and locating any cyberspace resource element based on an IP address of a key identifier of communication, wherein a Z-axis mapping algorithm is described as sorting, based on allocation time, all IP addresses under a certain AS in ascending order, and sorting IP addresses under the same allocation time from small to large in decimal, and serial numbers of the sorted IP addresses are mapped to a third-dimension coordinate system; and
analyzing and mapping the IP address by locating a coordinate based on a Hilbert algorithm and the Z-axis mapping algorithm.
