| 摘 要： | NAT-PT只能提供从IPv6到IPv4的单向连接,要实现从IPv4外网到IPv6网络的访问,这就必须结合DNS-ALG进行域名支持.提出了一种IPv4/IPv6转换网关的设计方案,在NAT-PT的基础上封装了一个应用层网关DNS-ALG.在应用层上实现了域名访问的透明性,从而屏蔽了网际协议不同对上层的影响,实现了IPv4与IPv6的双向连接.DNS-ALG是实现IPv4与IPv6网络双向访问的关键技术.

| Abstract: | NAT-PT can only provide the connection from IPv6 to IPv4 in one direction,In order to realize IPv4 network start communication with IPv6 network,DNS-ALG must be included to support name visiting.The article brings forward the scheme of IPv4/IPv6 translation gateway based on NAT-PT which packages an application layer gateway called DNS-ALG,realizes transparent communication in the application layer,shields the impact on the upper layer caused by different internet protocols,achieves the two-way connections b... |
