摘要
目前NAT64/DNS64已成为IPv6重要过渡技术。在实际项目实践过程我们发现,当IPv6用户访问IPv4资源时,如果某些应用层协议含有IPv4地址,将导致应用层业务无法正常工作。针对该问题本文提出一种基于代理的优化方法,通过中间代理服务器进行应用层地址翻译,实现了应用层业务的正常访问。基于真实实验环境对方案进行验证。实验结果表明,该优化方案能够有效解决原有NAT64/DNS64中应用层业务无法正常访问的问题。
Nowadays, NAT64/DNS64 has become an important IPv6 transition technology . In the progress of practical project, we discover that when an IPv6 user has access to the IPv4 content ,if some application layer protocol contains IPv4, application layer service cannot work correctly.To solve this problem, we propose an proxy-based optimization method, which leverages an intermediate proxy server to perform application layer translation and enable the application layer service. We validate this mechanism under a realexperimentalenvironment. Experimental results reveal that this mechanism can solve the problem that the application layer services with original NAT64/DNS64 technology fail to work .
