HTTPbis - bis 是什么意思?
我经常看到“bis”附加到协议版本(例如 v.34bis 或 httpbis)。
“bis”是什么意思或代表什么?
我认识的一位电信工程师认为它可能起源于法国。
I've often seen "bis" appended to versions of protocols (eg v.34bis or httpbis).
What does "bis" mean or stand for?
A telecom engineer I know thinks it might be French in origin.

正如其他人已经说过的,“bis”来自“两次”或“重复”。它用于指示某事物的第二种变体(尽管通常只有较小的变化,不保证有新名称)。
在 HTTP 上下文中,HTTPbis 是负责改进 HTTP 的工作组的名称。根据其章程:
最后一段(强调我的)解释了为什么他们在这种情况下使用“bis”,因为他们明确不想要新版本。
As others have already said, "bis" comes from "twice" or "repeat". It's used to indicate a second variant of something (although usually with only minor variations that don't warrant a new name).
In the context of HTTP, HTTPbis is the name of the working group in charge of refining HTTP. According to its charter:
The last paragraph (emphasis mine) explains why they've used "bis" in this context, since they explicitly don't want a new version.
bis
这个词(也用作前缀或后缀) bis 应用于某些调制解调器协议标准,是古拉丁语,意为“重复”(类似于古高地德语“两次”)。当协议以“bis”结尾时,意味着它是该协议的第二个版本。
同样,ter 源自古拉丁语,意思是“三次”。 V.xx 调制解调器协议中的后缀 terbo 是一个基于古拉丁语 ter 和单词 Turbo(拉丁语“旋转顶部”或“旋风”)的发明词,意思是“速度”。 V.32terbo 是 V.32 调制解调器协议开发的第三个版本..

bis
The word (also used as a prefix or suffix) bis , applied to some modem protocol standards, is Old Latin for "repeat" (akin to Old High German "twice"). When a protocol ends with "bis," it means that it's the second version of that protocol.
Similarly, ter is from Old Latin meaning "three times." The suffix terbo in the V.xx modem protocol is an invented word based on the Old Latin ter and the word turbo (Latin for "whirling top" or "whirlwind") meaning "speed." V.32terbo is the third version developed of the V.32 modem protocol..
