网络透明性

The Network Transparency

网络透明性指的是单一全局逻辑地址规范因特网概念,通过这种机制,信息包可以基本不改变地从源点送到目的地。端对端的问题及许多常见的网络设备(防火墙和NAT网关等)破坏了网络透明性。因特网的快速发展,商业网采用TCP/IP技术使用大量的私有地址空间,IPv4的地址空间已不能满足需要,网络透明性因而丢失。虽然采用了一些恢复网络透明性的措施和方案,但都没有很好的解决问题,网络透明性问题的解决需要一种全新的机制。

transparency refers to the original Internet concept of a single universal logical addressing scheme, and the mechanisms by which packets may flow from source to destinationessentially unaltered.The end to end problem and much familiar net device（firewa11 and NAT etc） destroy internet transparency, lntranet adopted the TCP/IP technology occupying much private address space with the speediness development, and IPv4 can not supply it, so the internet transparency lost.Although adopted much scheme to restore it, none do well.It need a entire new mechanism to resolve the problem.
