| 摘 要： | NAT-PT是实现IPv4/IPv6互访的关键技术，但单一的NAT-PT存在较多的缺点。该文引入NAT-PT簇来解决单一NAT-PT存在的问题，设计以DNS-ALG为调度中心的硬件结构和3层结构的软件系统，提出扩展加权系数轮转调度算法和动态阈值算法相结合的调度策略。实验证明，该软、硬件结构和调度策略可以弥补单一NAT-PT的缺点。

| Abstract: | NAT-PT is a key technology to implement intercommunication between IPv4 and IPv6, but the single NAT-PT has some defects. This paper proposes NAT-PT cluster to solve the problems of the single NAT-PT. The hardware structure uses DNS-ALG as the schedule center and three layer structure software system is designed. The schedule strategy which combines extended weights round robin algorithm with dynamic threshold algorithm is presented. The relevant experiments prove that the software and hardware structures as well as the schedule strategy are the right resolution for overcoming the defects of single NAT-PT. |
