| description | The invention discloses a routing and spectrum allocation method for spectrum adaptive sensing of a grid-free optical transport network, and belongs to the technical field of elastic optical networks. The method comprises the following steps: collecting network and service features, and generating a state space; determining a frequency spectrum slicing degree and an action space; establishing and training a dual-depth Q network model, and adjusting parameters; and according to the Double-DQN network after the training is completed, carrying out routing and spectrum allocation by adopting the SSD-DDQN. According to the method, the frequency spectrum distribution condition of the service on the link is reflected through the frequency spectrum slicing degree, meanwhile, the double-DQN model is introduced into reinforcement learning and combined with the frequency spectrum slicing degree, frequency spectrum fragment sensing and reinforcement learning are combined, self-adaptive frequency spectrum distribution is |
