摘要： 为解决虚拟数据中心内部虚拟网络间对物理带宽资源的竞争问题,借鉴博弈理论提出了网络资源分配模型.首先给出基于收益最优的整体带宽分配优化目标,然后将其拆分为可以运行于网络内部交换机上的分布式博弈模型,并给出了证明和求解过程,其中虚拟网络作为参与者在给定的定价机制下运行非合作的博弈,在博弈达到纳什均衡点时带宽分配最优.实验结果显示,提出的模型能够实现公平、合理的虚拟网络带宽资源分配.

Abstract: To solve the problem of the competition for physical bandwidth between virtual networks in virtual data center, a resource allocation model was proposed based on the game theory. Firstly, an overall profit optimization objective for bandwidth allocation of virtual networks was brought forward, and then the optimization problem was split into distributed game model, which can be implemented on the switches in the network. Under the given pricing mechanism, virtual networks run a non-cooperative game which achieves optimal bandwidth allocation at Nash equilibrium point. The proof and solution of the game model were also presented. Experimental results showed that the proposed model can achieve fair and rational bandwidth resource allocation among virtual networks.
