In respect of the security routing in optical networks, this paper proposes a new attack-aware routing algorithm for optical networks based on artificial fish swarm optimization in compliance with the Maximum Light path Attack Radius (MaxLAR) criterion, using the fast search and global optimization ability of the artificial fish swarm algorithm. This algorithm can find out the smallest maximum attack radius in light paths under given conditions, enhance the attack prevention ability of optical networks and minimize the possible damage to light paths caused by the potential physical-layer attacks. Algorithm analysis and Benchmark test function experiments indicate that this algorithm is feasible and has good performance.
