An attack impairment-aware multicast routing algorithm based on hyper-domain graph model in multi-domain optical network

In order to solve the problem of multicast attack impairment-aware routing in multi-domain optical network, an attack impairment-aware routing algorithm (HGFM) based on hyper -domain graph model is presented. In the proposed algorithm, the state vector and quantum rotation gate of quantum evolutionary is introduced into the polymorphic ant colony algorithm. The simulation experiments and analysis show that the proposed algorithm has better blocking performance compared with other algorithms without considering the attack impairments.
