1. A method for obtaining optical distribution network (ODN) logical topology information, comprising:
obtaining identification information of each first optical network unit (ONU) that is connected to a first passive optical network (PON) port and whose optical path changes and feature data of the first ONU in a first time window, wherein the feature data indicates data of a feature of a first ONU;
obtaining, based on the obtained feature data of each first ONU, a feature vector corresponding to the first ONU, wherein the feature vector corresponding to the first ONU indicates a change of the feature data; and
performing cluster analysis on the obtained feature vector corresponding to each first ONU to obtain topology information corresponding to the first PON port, wherein the topology information comprises identification information of at least one group of first ONUs, and identification information of each group of first ONUs indicating that the first ONUs in the group are connected to a same non-level-1 optical splitter,
wherein the performing cluster analysis on the feature vector corresponding to each first ONU to obtain topology information corresponding to the first PON port comprises:
obtaining, based on the feature vector corresponding to each first ONU, a similarity matrix between feature vectors corresponding to any two first ONUs; and
using all the obtained similarity matrices as input of a cluttering algorithm, to obtain the topology information corresponding to the first PON port.
