Multi-domain optical network multipoint crosstalk attack monitoring node selection and monitoring positioning method

The invention belongs to the technical field of multi-domain optical networks, and discloses a multi-domain optical network multipoint crosstalk attack monitoring node selection and monitoring positioning method. According to the method, the influence of the nodes in the network is described by utilizing different feature attribute access degrees and clustering coefficients of the nodes, a monitoring node set conforming to the monitoring density is obtained through a two-round selection mechanism, and the nodes with high influence in the network are selected as much as possible to place monitoring devices; the purposes of monitoring the crosstalk attack in real time and accurately positioning the source node of the crosstalk attack are achieved. 本发明属于多域光网络技术领域，公开了一种多域光网络多点串扰攻击的监测节点选择及监测定位方法。本发明利用节点不同的特征属性出入度和聚类系数描述节点在网络中的影响力大小，通过两轮选择机制得出符合监测密度的监测节点集，尽量选取网络中具有高影响力的节点放置监测器件，达到对串扰攻击实时监测和对串扰攻击源节点准确定位的目的。
