互联网中可用IPv4地址即将耗尽,因此全网过渡到IPv6已越加紧迫.为实现这两个互不兼容协议的通信,需使用IPv4/IPv6翻译机制.然而,人们对IPv4/IPv6翻译器的性能仍知之甚少,这将影响该机制在全网的部署.为了填补这一空缺,我们对典型的IPv4/IPv6翻译机制(IVI)进行测量;由于其已部署于100多所大学,因此测量结果将具有一定的参考价值.我们评估了网络层有效性,应用层可用性,以及端到端性能影响.结果显示,IVI在大多数情况下表现很好,但也存在一些可改进之处,包括:无法翻译某些类型的数据包,对端到端性能有一定的影响,不支持某些网络应用等.
Therefore, it is more and more urgent for the entire network to transition to IPv6. To implement these two incompatible protocols, IPv4 / IPv6 translation mechanism is required. However, IPv4 / IPv6 translator Performance is still poorly understood, which will affect the deployment of this mechanism across the entire network.To fill this gap, we measured a typical IPv4 / IPv6 translation mechanism (IVI); since it was deployed at more than 100 universities, measurements The results will be of some value for reference.We evaluated the effectiveness of the network layer, application layer availability, and end-to-end performance.The results show that IVI performed well in most cases, but there are some improvements that may include : Unable to translate some types of packets, have some impact on end-to-end performance, do not support certain web applications, and more.
