An attack-aware multicast routing algorithm based on game artificial fish model in multilayer and multi-domain optical networks

In order to solve the problem of multicast security routing in optical network, an attack-aware multicast routing algorithm based on game artificial fish model in multi-layer and multiregion optical networks (GAFM algorithm) is proposed. In the proposed algorithms, the MaxLAR guidelines and the game artificial fish model (GAF) to describe the logical topology are used. The GAFM algorithm not only can find out the smallest light path attack radius in light paths under the given condition, but also can enhance the capacity of optical network attack prevention and reduce the light damage by the potential physical-layer attacks. Finally, the simulation results show that the algorithm is feasible and has achieved good network performance.
