Abstract

The invention belongs to the technical field of wireless communication, specifically a decision method for a mapping policy in a virtual network. The method comprises the steps of establishing a Markov decision process optimization model according to mapping resources; solving a centralized optimum mapping policy through adoption of a Markov decision process; defining various virtual network requesters as buyers and defining substrate networks as sellers, and establishing a Stackelberg buying and selling model; solving a current equilibrium solution of a Stackelberg game and taking the currentequilibrium solution as the optimum resource capacity and the optimum selling price in a current phase; predicting a future equilibrium solution, and taking the future equilibrium solution as the optimum resource capacity and the optimum selling price in a future phase; and evaluating a mapping relationship between the buyers and the sellers according to the current equilibrium solution and the future equilibrium solution, thereby determining a distributed optimum mapping policy. According to the method, the load balance of the substrate networks is effectively improved, and the network performance is optimized.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and specifically relates to a decision-making method for a mapping strategy in a virtualized network. Background technique

[0002] With the development of emerging technologies such as cloud computing, the Internet of Things, and future 5G, it has become increasingly difficult for existing infrastructure to meet the needs of different technologies and applications. In the past few decades, in order to meet the needs of communication, the way for governments to solve the above problems is to deploy a large number of infrastructures, which leads to the complexity and heterogeneity of the existing network, and the network becomes rigid and difficult to manage flexibly. If you blindly deploy new networks, in addition to facing high capital investment, it will also affect the deployed infrastructure, resulting in lower resource utilization, unnecessary investment and waste, and conflic...
