Embodiment Construction
[0018] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0019] In the embodiment of the present invention, the existing optical cable section information is recursively queried in terms of depth and breadth until all sites that are directly or indirectly connected with the current site by optical cables are queried to form a site list, and the cable section database is obtained by querying the optical cable section database according to the site list. Information about the complete fiber optic network topology.
[0020] An embodiment of the present invention provides a method for generating an optical cable network topology, such as figure 1 shown, including:
[0021] The optical cable segment information step is to obtain all the optical cable segment information starting from or ending at the first designa...

Embodiments of the invention provide an optical cable network topology generation method and apparatus. The method comprises: obtaining all optical cable section information taking a first specified site as a start or stop point, and taking the first specified site as a current site; a first step of recursion: obtaining the current site and all related sites directly connected with the current site to form a site list; a second step of recursion: taking out one site from the site list as the current site, adding a query mark for the current site, storing the current site carrying the query mark in a site data structure, traversing a next site from the site list, and if the next site is not in the site data structure, adding the next site into the site data structure and adding a non-query mark for the next site; taking the next site as a new current site, and calling the first step of recursion until sites in the site data structure are all marked to be queried; and querying an optical cable section database according to the site data structure to obtain an optical cable network topology.
Description
technical field [0001] The invention relates to optical cable network technology, in particular to a method and device for generating optical cable network topology. Background technique [0002] The status information of the optical cable network is stored in the optical cable section table. When formulating the networking plan, the information of the optical cable section is repeatedly queried according to the sites that need to be networked. Each query can only obtain the information of the adjacent sites that have optical cable connections with the current site. , for the case of jumping through one or more sites to realize intercommunication in the actual networking, multiple queries and manual records are required. [0003] In actual optical cable construction, a considerable part of the optical cable intercommunication between sites is realized by jumping different optical cable segments. In order to realize jump-connection networking, as far as the prior art is conc...
