【摘要】 IPv6是云计算平台基础架构的未来优化趋势之一。针对IPv4Web应用向IPv6云平台的部署的过程,由于IP地址的兼容性问题而导致运行失败的问题,提出了一种利用虚拟代理服务,实现WEB应用向IPv6云计算平台动态部署的机制。通过重新构造HTTP头部实现了访问者真实地址的传递。该机制具有对弹性透明、自助服务的特点。实验结果显示在不同的负载规模下,平均响应时间的延长比率低于8%,对用户的访问影响较小。实验结果证明该机制是有效的。更多还原

【Abstract】 IPv6 is a trend in the cloud infrastructure optimization.In order to overcome limitations of IPv4 Web applications failing in the cloud adopting IPv6,caused by IP address compatibility,this paper designed an elastic and self-service development method.The method deployed and instantiates a custom virtual proxy service for a web application on demand,then the virtual proxy service plays as a middle man in a visitor and a provider,translating the IP address and redirecting the responses and requests,and finally the visitor accesses the web application via the virtual proxy service founded by a domain name specified from a dynamic IPv6 DNS.An HTTP header rebuilding method is adopted for delivering a real source address.Experimental results show the increasing rate of average response time was less than 7%in different load scales.The method was proved to be effective.更多还原
