<p>The present invention discloses a method for guaranteeing service continuity on the basis of a "2D matrix-based distributed access network". More particularly, the present invention relates to a method for reducing an overall error and cost-effectively guaranteeing service continuity by separating a configuration of a system into a terminal unit, a distributed access unit, and an original server unit to deal with potential threats to "service availability" due to a distributed denial of service (DDoS) attack or an error in an exposed service interval. According to an embodiment of the present disclosure, the terminal unit communicates with the original server unit through the distributed access unit since an access path is automatically distributed according to a predetermined rule when a security module is installed, and the original server unit communicates with the terminal unit without being exposed to an attacker. According to an exemplary embodiment of the present invention, the convergence of a dynamic operation technology and a security element technology of the distributed access network can solve problems regarding a huge investment in threats such as the DDoS and regarding potential threat factors for various service availabilities at once.</p> |
