We consider a fixed/flexible grid optical network. fixed and flexible grid technologies coexist. In such an optical network, fixed grid technology and flexible grid technology coexist. we combine distance adaptive spectrum resource assignment and sub-tree division for multicast services, aiming to improve the process of multicast routing and spectrum allocation, so as to accommodate more multicast sessions. It can be seen from the simulation results that the performance of our proposed method with respect to blocking probability and resource consumption ratio in the simulation environment, which demonstrate an improvement over traditional method.
