摘　　要：针对很多高校新建了一些IPv6网络而不能实现与原有IPv4网络通信的问题,引入NAT-PT,并与应用层网关(主要为DNS-ALG)结合,实现了IPv6网络和IPv4网络间的互通。通过分析NAT-PT和DNS-ALG的工作原理,阐述了IPv6侧主机发起通信和IPv4侧主机发起通信的工作过程,通过引入NAT-PT簇和修改DNS服务器,从而解决了2个网络的通信质量和负载平衡问题,并通过试验进行验证。For the problem to a lot of colleges and universities building a number of IPv6 networks not to achieve the communication with the existing IPv4 network,this article introduces NAT-PT and Application Layer Gateway（mainly the DNS-ALG） combined to implement the intercommunication between IPv6 networks and IPv4 networks.Through the analysis of NAT-PT and DNS-ALG of the working principle,we explain the working process in host-side IPv6 initiated communication and initiated the communication by the IPv4 host-side,by using NAT-PT Cluster and modifying DNS Server,so as to solve the communication quality and the load balancing between IPv4 and IPv6 networks,and verify through experiments.
