Network slice deployment method based on joint optimization

The invention discloses a network slice deployment method based on joint optimization, belongs to the technical field of network slice deployment, and solves the problem of low network slice resource scheduling and deployment efficiency in the prior art. The method comprises the following steps: for each network slice in a network slice set, respectively calculating the importance of each physical node in a physical network and each virtual node in the network slice based on a multi-attribute decision-making method, and pre-deploying the network slice based on the importance of each node; performing joint optimization on the pre-deployed mapping parameters by taking resource efficiency maximization of the network slice set as an optimization target to obtain optimal mapping parameters; and for each network slice in the network slice set, respectively recalculating the importance of each physical node in the physical network and each virtual node in the network slice based on a multi-attribute decision-making
