TCP 兼容性:为什么 TCP 与数据包广播和多播操作不兼容? [英] TCP compatibility: Why is TCP not compatible with packet broadcast and multicasting actions?

问题描述

** http://en.wikipedia.org/wiki/User_Datagram_Protocol:**

与 TCP 不同，UDP 与数据包广播(发送到本地网络上的所有用户)和多播(发送到所有订阅者)兼容."

推荐答案

Compatible"在这里用词非常糟糕.支持"才是真正被描述的东西.TCP 是一种点对点协议，从设计上来说.时期.TCP 多播在术语上是自相矛盾的.

'Compatible' is a very poor choice of words here. 'Supports' is what is really being described. TCP is a point to point protocol, by design. Period. TCP multicast is a contradiction in terms.

我更新了维基百科页面以反映此评论.

I updated the Wikipedia page to reflect this comment.

编辑 2:令人难以置信的是，自从发布这个问题以来，有人已经从维基百科 UDP 页面中删除了所有提到的多播.我修好了它.再次.

EDIT 2: Incredibly enough, somebody has removed all mention of multicast from the Wikipedia UDP page since this question was posted. I fixed it. Again.
