Network function chain deployment method and device, terminal equipment and storage medium

The embodiment of the invention discloses a network function chain deployment method, and the method comprises the steps: receiving a deployment request of a network function chain, obtaining the topological information of a plurality of nodes used for deploying a virtual network function, and building a target function with the shortest end-to-end time delay, wherein the target function meets reliability constraints on nodes, resource capacity constraints of the nodes and reliability constraints on links during virtual network function deployment; when the network function chain is deployed, according to deployment information carried by the virtual network function and topological information of the multiple nodes, searching the nodes satisfying the target function for deployment, thereby effectively ensuring the transmission reliability while satisfying the low-delay network service request. The embodiment of the invention also correspondingly provides a network function chain deployment device, terminal e
