Flexible Ethernet time slot allocation method and device based on improved differential evolution algorithm

The invention discloses a flexible Ethernet time slot allocation method and device based on an improved differential evolution algorithm. Aiming at an internal time slot cross scene of a multi-service mixed device, in order to reduce service transmission time delay and jitter as much as possible, a fitness function oriented to global time delay and jitter performance is designed based on a flexible Ethernet small particle time slot distribution principle; and solving the optimal time slot crossing strategy by adopting an improved differential evolution algorithm fusing a sine and cosine algorithm and a simulated annealing algorithm. According to the algorithm provided by the invention, the global search capability can be increased during problem solving, the algorithm is prevented from falling into a local optimum condition, the network transmission target requirements of minimum jitter and minimum time delay in a multi-service flexible application scene are met, and the network transmission performance is re
