Deployment method of virtualized network service function chain based on deep reinforcement learning

Abstract

The invention relates to a virtualized network service function chain deployment method based on deep reinforcement learning, which is used to solve the problem of virtualized network service function deployment under the background of edge computing, and belongs to the technical field of edge computing. This method, by solving the two problems of virtual function placement and traffic routing respectively, realizes the deployment of the service function chain at the minimum cost, and can take advantage of deep reinforcement learning to adapt to the time-varying traffic control requirements. This method uses the neural network as the basis for the accumulated reward Q value. In addition, deep reinforcement learning introduces the concept of an experience pool when inputting samples to a neural network. The present invention considers not only the total cost but also the end-to-end delay, especially the intermediate processing delay, and is suitable for applications in dynamic and complex scenarios requiring high communication cost and delay of the server.
