Abstract： |
The utility model discloses an IP backbone topology discovery method, pertaining to the field of computer network administration. The method can pre-set the maximal value of the discovery depth and read IP address of the seed router to obtain all of the port address and sub-net mask code of the router. As per the port address and the sub-net mask code, the sub-network address can be calculated. Such sub-network address is connected with the router. Based on the calculated sub-network address, deducing the IP address which is correspondent to the sub-net; the deduced IP address is chosen as the IP address for the router to conduct the respective self-adapting and intelligent judgment & analyzing; the connected relation for the discovered router IP address shall be kept; the discovered depth is added with 1 to judge whether the discovered depth is no less than the maximal value. If yes, it is over, or the router subjecting to the discovered IP address shall be placed in the list to be discovered. The utility model gradually extends from the router to be discovered to the outside, so as to self-adapt and discover various IP backbones' topology connection relation accurately and effectively. |
