摘　　要：从博弈论的角度提出了一种新的流量均衡机制:攻防双方的行为被描述成一种双局中人的、非合作的博弈过程.在此过程中,攻击者欲通过攻击传输路径中的某个节点来最大化自己的收益;传输者则欲通过在网络拓扑中选择一条或数条合适的路径使得自己的传输代价最小.从理论上证明了该博弈过程的纳什均衡解的存在性,给出的实验结果证明了所提出的流量均衡机制优于传统机制.This paper proposes a new load balancing scheme in MPLS （multi-protocol label switching） network under adversarial uncertainty： the actions of the attacker and defender are depicted within a two-person, non-cooperative and nonzero-sum bimatrix game model. In this model, the attacker tries to maximize his utility via attacking some node along the transmission path, while the defender attempts to choose a most suitable path from the network topology to achieve minimum cost. The paper proves the existence of the Nash equilibrium theoretically, and the experimental results show that the superiority of the proposed scheme comparing to the traditional load balancing scheme in MPLS network.
