Dynamic deployment method and device of service function chain and computer equipment

The invention discloses a dynamic deployment method and device of a service function chain and computer equipment. The dynamic deployment method comprises the steps of: acquiring a topological structure of a target service function chain and a physical network; acquiring a plurality of virtual network functions and a plurality of virtual links in the target service function chain, and acquiring a plurality of physical nodes and a plurality of physical links in the topological structure of the physical network; further determining the priority of each virtual network function and the priority of each physical node, and determining a target deployment scheme of the virtual network function; determining all possible mapping paths; establishing an objective function and a target constraint condition according to the plurality of virtual network functions, the plurality of virtual links, the plurality of physical nodes and the plurality of physical links; and determining an optimal path for deploying the target se
