Embodiment Construction
[0084] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0085] There are generally two kinds of traditional ODN network planning ideas: top-down, planning from OLT to user terminals; bottom-up, planning from user terminals to OLT. A planning system scheme combining up and down is proposed; specifically, it is an optical access network ODN intelligent clustering planning method for sparse user distribution, which mainly uses the ODN (Passive Optical Network) of PON (Passive Optical Network) in the access network. opticaldistribution network (optical distribution network) network planning, clustering programming algorithm and spanning tree algorithm, etc.
[0086] In the wiring section of the ODN network, the clustering algorithm (k-means) is used to randomly generate the initial centroid, and then the cost function T is constructed. After multiple iterations of the initial centroid, the centroid value that minimize...
