摘要
NAT-PT技术和PROXY技术是HTTP服务从IPv4向IPv6过渡的两种主要技术,文章讨论了基于这两种技术的过渡方案的实现与改进。论文从原理上分析现有方案,提出现有实现方案存在的问题,如NAT-PT中的动态映射地址对过期而导致的访问出错的问题,以及PROXY方案中IPv4端不能通过IPv6地址直接访问的问题。针对上述问题提出了改进方案,并通过实验证明了改进方案的可行性和有效性。
This paper presents some improving mechanisms for two kinds of IPv4/IPv6 transition schemes for HTTP, which are based on NAT-PT and PROXY.A theoretic description of the two schemes is given firstly.Then several problems with the two schemes are discussed,such as access interruption induced by mapping address going out of time in NAT-PT,and the problem that IPv4 client can not access IPv6 server with IPv6 address in PROXY scheme.To resolve these problems,some improving mechanisms are put forward.At last,some experiments are carried out to prove the feasibility and effectivity of the improved IPv4/IPv6 transition schemes for HTTP.
