Assessing the Safety Risk Grade of Optical Network from the Network Geography Distribution

摘要

From the perspective of network geography distribution,we divide the network into seven parts,and on this condition,we firstly adopt the algorithm of WLGM to the topology of the network,and find out the aggregation of worst line cut of the network,and then we introduce the concept of safety risk rating,assessing the safety risk grade of the seven parts.Then,we obtain simulation results for specific backbone networks,thereby demonstrating the applicability of our algorithms to real-world scenarios.The work is useful to improving the survivability of optical network.
