摘　　要：NAT-PT是IPv4过渡到IPv6时互访的关键技术,但单一的NAT-PT负载过重。为了提高跨域访问通信质量,解决其负载过重的问题,特引用NAT-PT簇,详细地设计出NAT-PT簇系统的软件和建立了硬件模型,提出基于DN S-ALG为中心的扩展加权系数的轮转调度算法和动态阀值算法相结合负载平衡策略,实验证明,该方法很好地解决了单一NAT-PT的负载过重问题。NAT-PT （network address translation-protocol translation） is a key technology to implement IPv4/IPv6 intercommunication, and the single NAT-PT should be overload in this environment. In order to improve the communication quality of span domain to solve the overload problem, in this paper, the software and hardware models of load balance for NAT-PT cluster are designed in detail, and then, the load balance strategy based on DNS-ALG is presented, which combines extended weighted round robin algorithm of load balance with dynamic threshold algorithm of load balance. The experiment demonstrates that the overload of the single NAT-PT is solved effectively.
