ip - 为什么 IPv5 从未被使用过？

Question

只是想知道为什么 IPv5 从未被使用过？它是基于 ST-II 的吧？如果我没有 100% 错误的话，这是 IPv4 的 QoS 扩展。

这是否也与RSVP协议(protocol)的比较有关？

Answer 1

来自what ever happened to ipv5:

In the late 1970’s, a protocol named ST — The Internet Stream Protocol — was created for the experimental transmission of voice, video, and distributed simulation. Two decades later, this protocol was revised to become ST2 and started to get implemented into commercial projects by groups like IBM, NeXT, Apple, and Sun. Wow did it differ a lot. ST and ST+ offered connections, instead of its connection-less IPv4 counterpart. It also guaranteed QoS. ST and ST+, were already given that magical “5″. And now as the Internet clock ticks, our PCs don’t use IPv5. So we’re moving onto 6.
