英文摘要：

According to the vulnerability of the optical network from the geography distribution, the model of accessing the vulnerability of optical network was constructed based on restoration technology. Using binary search algorithm on the parameter I, the minimum of the maximum flow of the residual network was computered. Simulation results show that, compared to the results reported in other references, the scheme can effectively computer the vulnerability of the optical network and simultaneously reduce the time complexity of algorithm.
