Claim 2:
3. The method according to claim 1, wherein said constructing the cyberspace map model based on the cyberspace coordinate system and the framework for the three-dimensional cyberspace coordinate system comprises:
determining that a hierarchical structure of a cyberspace is divided into three layers: the AS, a network, and an IP; and
defining a sphere mode of cyberspace, wherein the AS is mapped to another three-dimensional space by adopting a force-directed algorithm and taking the AS as a node in the force-directed algorithm, the AS being denoted as a sphere in the other three-dimensional space, and the sphere having a size positively correlated to a number of IP addresses under the AS.
